Benzydamine hydrochloride ameliorates ethanol-induced inflammation in RAW 264.7 macrophages by stabilizing redox homeostasis

Objective:To evaluate the protective effect of benzydamine hydrochloride against ethanol-induced oxidative stress and inflammation in RAW 264.7 macrophages.Methods:RAW 264.7 macrophages were treated with ethanol(100 mM)and benzydamine hydrochloride(7.5μM).The imflammatory status was confirmed by measuring pro-(TNF-αand IL-6)and anti-inflammatory(IL-10)cytokines through ELISA and RT-PCR assays.Reactive oxygen species generation and mitochondrial membrane potential were investigated to study the protective role of benzydamine hydrochloride against ethanol-induced oxidative stress.Apoptosis detection was also investigated using flow cytometry and acridine orange/ethidium bromide staining.Results:Benzydamine hydrochloride significantly decreased the secretion of TNF-αand IL-6,as well as the generation of reactive oxygen species inside the cells,thereby stabilizing the mitochondrial membrane potential and reducing DNA fragmentation.The ethanol-induced cellular necrosis was also reversed by the administration of benzydamine hydrochloride.Conclusions:Benzydamine hydrochloride ameliorates ethanol-induced cell apoptosis and inflammation in RAW macrophages.

Design and optimization of a greener sinomenine hydrochloride preparation process considering variations among different batches of the medicinal herb

The current methods used to industrially produce sinomenine hydrochloride involve several issues,including high solvent toxicity,long process flow,and low atomic utilization efficiency,and the greenness scores of the processes are below 65 points.To solve these problems,a new process using anisole as the extractant was proposed.Anisole exhibits high selectivity for sinomenine and can be connected to the subsequent water-washing steps.After alkalization of the medicinal material,heating extraction,water washing,and acidification crystallization were carried out.The process was modeled and optimized.The design space was constructed.The recommended operating ranges for the critical process parameters were 3.0–4.0 h for alkalization time,60.0–80.0℃ for extraction temperature,2.0–3.0(volume ratio)for washing solution amount,and 2.0–2.4 mol·L^(-1) for hydrochloric acid concentration.The new process shows good robustness because different batches of medicinal materials did not greatly impact crystal purity or sinomenine transfer rate.The sinomenine transfer rate was about 20%higher than that of industrial processes.The greenness score increased to 90 points since the novel process proposed in this research solves the problems of long process flow,high solvent toxicity,and poor atomic economy,better aligning with the concept of green chemistry.

Method Verification and Validation of Hydralazine Hydrochloride: Spectrophotometric Analysis in Pure and Pharmaceutical Formulations

The new method proposed is based on the formation of hydralazine-Bromophenol blue ion pair simply and without further extraction or heating. The ion pair was prepared in the presence of pH 3 citrate buffer forming a yellow-colored chromogen. A new maximum UV-visible band formed at 416 nm. The color was stable for more than 10 hours and obeyed Beer’s Law over the concentration range of 10 - 50 µg/mL. The calculated molar absorptivity and Sandell’s sensitivity were 1.01 × 104 L∙mol−1∙cm−1 and 0.0514 µg/mL, respectively. The elements of method validation stipulated by The International Conference on Harmonization [Q2 (R1)] were applied for hydralazine hydrochloride assay in pure and pharmaceutical tablet formulation. The average recoveries of the pure solution and the pharmaceutical formulation were 98.94% and 99.50%, respectively. The results were statistically compared by F-test, which indicates that the method can be precise and repeatable for both pure and pharmaceutical solutions. The method was found to be accurate, reproducible, and cost-effective, and validated for the assay of hydralazine in terms of the routine quality control.

Carbon-doped CuFe_(2)O_(4) with C-O-M channels for enhanced Fenton-like degradation of tetracycline hydrochloride: From construction to mechanism

Carbon-doped copper ferrite(C–CuFe_(2)O_(4))was synthesized by a simple two-step hydrothermal method,which showed enhanced tetracycline hydrochloride(TCH)removal efficiency as compared to the pure CuFe_(2)O_(4) in Fenton-like reaction.A removal efficiency of 94%was achieved with 0.2 g L^(-1) catalyst and 20 mmol L^(-1) H_(2)O_(2) within 90 min.We demonstrated that 5%C–CuFe_(2)O_(4) catalyst in the presence of H_(2)O_(2) was significantly efficient for TCH degradation under the near-neutral pH(5–9)without buffer.Multiple techniques,including SEM,TEM,XRD,FTIR,Raman,XPS M€ossbauer and so on,were conducted to investigate the structures,morphologies and electronic properties of as-prepared samples.The introduction of carbon can effectively accelerate electron transfer by cooperating with Cu and Fe to activate H_(2)O_(2) to generate·OH and·O_(2)^(-).Particularly,theoretical calculations display that the p,p,d orbital hybridization of C,O,Cu and Fe can form C–O–Cu and C–O–Fe bonds,and the electrons on carbon can transfer to metal Cu and Fe along the C–O–Fe and C–O–Cu channels,thus forming electron-rich reactive centers around Fe and Cu.This work provides lightful reference for the modification of spinel ferrites in Fenton-like application.

Clinical effect of acupuncture at ghost points combined with fluoxetine hydrochloride on mild-to-moderate depression

BACKGROUND Depression is a common,chronic,and recurrent mood disorder that has become a worldwide health hazard.Fluoxetine hydrochloride,a common treatment method,can inhibit 5-hydroxytryptamine(5-HT)recycling in the presynaptic membrane;however,the efficacy of a single drug is inadequate.At present,mildto-moderate depression can be treated with acupuncture of ghost caves,but the clinical curative effect of combined therapy with fluoxetine hydrochloride has not been sufficiently reported.AIM To evaluate the clinical effect of acupuncture at ghost points combined with fluoxetine hydrochloride in the treatment of mild-to-moderate depression.METHODS This retrospective study included 160 patients with mild-to-moderate depression who were admitted to Shanghai Hospital of Integrated Traditional Chinese and Western Medicine,Affiliated to Shanghai University of Traditional Chinese Medicine,between January 2022 and June 2023.Patients were separated into a single-agent group(fluoxetine hydrochloride treatment,n=80)and a coalition group(fluoxetine hydrochloride treatment combined with acupuncture at ghost points,n=80).Pre-treatment symptoms were recorded,and the clinical curative effect and adverse reactions[Asberg Antidepressant Side Effects Scale(SERS)]were assessed.Depression before and after treatment[Hamilton Depression Scale(HAMD)-24],neurotransmitter levels[5-HT,norepinephrine(NE),dopamine(DA)],oxidative stress indicators[superoxide dismutase(SOD),malondialdehyde(MDA)],and sleep quality[Pittsburgh Sleep Quality Index(PSQI)]were compared.RESULTS The total efficacy rate was 97.50%in the coalition group and 86.25%in the single-agent group(P<0.05).After 2,4,6,and 8 wk of treatment,the HAMD,self-rating depression scale,and SERS scores of the coalition and single-agent groups decreased compared with pre-treatment,and the decrease was more significant in the coalition group(P<0.05).After 8 wk of treatment,the levels of NE,DA,5-HT,and SOD in the coalition and single-agent groups increased,while the levels of MDA decreased;the increases and decrease in the coalition group were more significant(P<0.05).The PSQI scores of the coalition and single-agent groups decreased,and the decrease was more significant in the coalition group(P<0.05).CONCLUSION Acupuncture at ghost points combined with paroxetine tablets can safely improve depressive symptoms and sleep disorders,regulate neurotransmitter levels,and reduce stress responses in patients with mild-to-moderate depression.

Hypidone hydrochloride(YL-0919)ameliorates functional deficits after traumatic brain injury in mice by activating the sigma-1 receptor for antioxidation

Traumatic brain injury involves complex pathophysiological mechanisms,among which oxidative stress significantly contributes to the occurrence of secondary injury.In this study,we evaluated hypidone hydrochloride(YL-0919),a self-developed antidepressant with selective sigma-1 receptor agonist properties,and its associated mechanisms and targets in traumatic brain injury.Behavioral experiments to assess functional deficits were followed by assessment of neuronal damage through histological analyses and examination of blood-brain barrier permeability and brain edema.Next,we investigated the antioxidative effects of YL-0919 by assessing the levels of traditional markers of oxidative stress in vivo in mice and in vitro in HT22 cells.Finally,the targeted action of YL-0919 was verified by employing a sigma-1 receptor antagonist(BD-1047).Our findings demonstrated that YL-0919 markedly improved deficits in motor function and spatial cognition on day 3 post traumatic brain injury,while also decreasing neuronal mortality and reversing blood-brain barrier disruption and brain edema.Furthermore,YL-0919 effectively combated oxidative stress both in vivo and in vitro.The protective effects of YL-0919 were partially inhibited by BD-1047.These results indicated that YL-0919 relieved impairments in motor and spatial cognition by restraining oxidative stress,a neuroprotective effect that was partially reversed by the sigma-1 receptor antagonist BD-1047.YL-0919 may have potential as a new treatment for traumatic brain injury.

Design and optimization of purification process of sinomenine hydrochloride

Sinomenine hydrochloride is generally produced from Caulis Sinomenii. At present, the purification process in industrial production suffers from large amount of solid waste, high solvent toxicity, and low sinomenine hydrochloride yield. In this study, a new purification process for sinomenine hydrochloride was proposed by using the extract obtained from acid extraction of Caulis Sinomenii as the starting material.The process included the following steps: alkalization, extraction, water washing, acid–water stripping,drying, and crystallization. 1-Heptanol was used as the extractant. The distribution coefficients of sinomenine and sinomenine hydrochloride in 1-heptanol–water system were 27.4 and 0.0167, respectively.The dissociation constants of sinomenine hydrochloride were 8.27 and 11.24, respectively. Process parameters of the new purification process were optimized with experimental design. The extractant1-heptanol and sinomenine hydrochloride in the crystallization mother solution can be recycled in the new process. The purity of the obtained sinomenine hydrochloride crystals exceeded 85%, and the yield was about 70%. Compared with current industrial processes, safer extractant, less solid waste, and higher sinomenine hydrochloride yield can be achieved using the new purification process of sinomenine hydrochloride provided in this study.

Doxycycline hydrochloride and florfenicol combination(DoxHcl&FF)is an effective treatment for respiratory diseases.In the study,our objective Was to evaluate the activity of DoxHcl&FF against Actinobacillus pleuropneumoniae(APP)in porcine pulmonary epithelial lining fluid(PELF)and the optimal dosage scheme to avoid the development of resistance.The DoxHcl&FF Was administered intramuscularly(IM)at 20mg/kg,and the PELF was collected at differ-ent time points.The minimum inhibitory concentration(MIC)and time-mortality curves were also included in the study.Based on the sigmoid Emax equation and dose equations,the study integrated the in vivo pharmacokinetic data of infected pigs and ex vivo pharmacodynamic data to obtain the area under concentration time curve(AUCo-24h)MIC values in PELF and achieve bacteriostatic activity,bactericidal activity and the virtual eradication of bacteria.The study showed that the combination of DoxHcl and FF caused no significant changes in PK parameters.The peak concentration(Cmax)of FF in healthy and diseased pigs was 8.87±0.08 and 8.67±0.07μg/mL,the_AUCo-24h were.172.75±2.52 and 18022±3.13 h-μg/mL,the Cmax of DoxHcl was 7.91±0.09 and 7.99±0.05μg/mL,and the AUCo-24h was 129.96±3.70 h-μg/mL and 169.82±4.38 h-μg/mL.DoxHcl&FF showed strong concentra-tion-dependent tendencies.The bacteriostatic,bactericidal,and elimination activity were calculated as 5.61,18.83 and 32.68 h,and the doses were 1.37(bacteriostatic),4.59(bactericidal)and 7.99(elimination)mg/kg.These findings indicated that the calculated recommended dose could assist in achieving more precise administration,increasing the effectiveness of DoxHcl&FF treatment for APP infections.

Volumetric and ultrasonic properties of thiamine hydrochloride drug in aqueous solutions of choline-based deep eutectic solvents at different temperatures

Important efforts have been made over the past years to improve the drug acts,which leads to the discovery of novel drug preparations and delivery systems.The optimal design of such processes requires a molecular-level understanding of the interactions between drug molecules and biological membranes.The thermodynamic investigation provides deep and complete knowledge of interactions and the choice of appropriate and suitable production compounds in pharmaceutical fields.Particularly,the analysis of drugs+co-solvents in aqueous media is the central issue in many types of research because they exert their impact by interacting with biological membranes.This work is aimed to measure the density and speed of sound for the thiamine hydrochloride in water+deep eutectic solvents(DESs)mixtures(choline chloride/urea,choline chloride/ethylene glycol and choline chloride/glycerol)at temperature range(293.15-308.15)K.By correlation of the evaluated parameters in some standard relations,the partial molar parameters i.e.apparent molar volumes,Vφ,m,and apparent molar isentropic compression,κ_(s,φ,m),are calculated.In addition,apparent molar isobaric expansion,E^(0)_(φ,m),and Hepler’s constant are computed from the density and speed of sound data.For fitting the experimental Vφ,m andκ_(s,φ,m)the Redlich-Meyer equation was employed that the important quantities;standard partial molar volume,V^(0)_(m),and partial molar isentropic compression,κφ,m0,were obtained.The thermodynamic analysis of the studied system also plays a crucial role in the pharmaceutical industry.

Application of sintilimab combined with anlotinib hydrochloride in the clinical treatment of microsatellite stable colorectal cancer

BACKGROUND Microsatellite stable(MSS)colorectal cancer(CRC)is a common type of tumor with limited treatment options.Sintilimab and anlotinib hydrochloride are two extensively studied anticancer drugs.AIM To probe the clinical value of combining sintilimab with anlotinib hydrochloride in MSS CRC treatment.METHODS During the period spanning from April 2019 to April 2022,Zhejiang Provincial People’s Hospital accommodated a cohort of 92 patients diagnosed with MSS CRC who were classified into two distinct groups in our study,the observation group and the control group.The control group was administered anlotinib hy-drochloride as their designated therapy,whereas the observation group received the additional treatment of sintilimab in conjunction with the therapy assigned to the control group.The administration of treatment occurred in cycles consisting of a duration of 3 wk,and the evaluation of effectiveness took place subsequent to the completion of two consecutive cycles of treatment within both groups.A comparative analysis between the two groups was conducted to assess the short-term efficacy and ascertain the incidence of adverse events transpiring throughout the duration of the treatment period.Changes in the levels of carcinoembryonic Life Questionnaire-Core 30 were compared between the two groups prior to and subsequent to therapy.Finally,a 1-year follow-up was conducted for both groups of patients,and the survival status was recorded and analyzed.RESULTS The short-term effectiveness displayed by the observation group surpassed that exhibited by the control group,with a statistically significant discrepancy(76.09%vs 50.00%),reaching a significance level denoted as P<0.05.Following the administration of treatment,the observation group manifested a considerable reduction in numerous serum indicators,which were found to be lower than the corresponding pretreatment levels within the same group as well as the post-treatment levels observed in the control group(P<0.05).Post-treatment,the T lymphocyte subset levels within the observation group demonstrated a remarkable amelioration,surpassing the corresponding pre-treatment levels observed within the same group as well as the post-treatment levels observed in the control group(P<0.05).Subsequent to the therapeutic intervention,the observation group showcased a notable amelioration in the scores associated with multiple dimensions of life quality.These scores outperformed the pretreatment scores within the same group as well as the post-treatment scores observed in the control group(P<0.05).The safety levels of drug use in the two group were comparable(19.57%vs 13.04%),and no distinct difference was observed upon comparison(P>0.05).After the completion of treatment,both groups of patients underwent a 1-year follow-up outside the hospital.Throughout this period,1 patient within the observation group and 2 patients within the control group became untraceable and were lost to follow-up.During the follow-up period of the observation group,12 patients died,resulting in a survival rate of 73.33%(33/45),while in the control group,21 patients died,resulting in a survival rate of 52.27%(23/44).The implementation of Kaplan-Meier survival analysis revealed a conspicuous contrast in survival rates exhibited by the two groups(log-rank=4.710,P=0.030).CONCLUSION The combination of sintilimab and anlotinib hydrochloride demonstrated favorable efficacy in the treatment of MSS CRC patients,leading to improvements in patient immunity and prognosis.Additionally,it exerted inhibitory effects on the expression of carcinoembryonic antigen,CA199,and CA125.

Physico-chemical parameters for the assembly of moxifloxacin hydrochloride and cetyltrimethylammonium chloride mixture in aqueous and alcoholic media

The aggregation behavior of the mixture of cetyltrimethylammonium chloride(CTAC), a cationic surfactant, and moxifloxacin hydrochloride(MFH), a fourth-generation fluoroquinolone antibiotic drug, has been studied using the conductivity technique in aqueous and alcoholic(EtOH, 1-PrOH, and 2-BuOH)media. The study was performed at several temperatures between 298.15 and 323.15 K at 5 K intervals.The assembly has been characterized by evaluating the micellar parameters, such as the critical micelle concentration(CMC) and the counter ion binding(β), of the CTAC + MFH mixture. The values of the CMC for the assembly of the CTAC + MFH mixture were reliant on the composition of alcohols in the mixed solvents and the temperature. The CMC values of the CTAC + MFH mixture increased with increasing temperature;that is, assembly was delayed by increased temperature. The micellization of the CTAC + MFH mixed system was delayed in alcoholic media. The observed-ΔG0mvalues for the association of the CTAC + MFH mixed system demonstrated a spontaneous aggregation process under all study conditions.Based on the-ΔH^(0)_(m) and +ΔS^(0)_(m) values, the association of the CTAC + MFH mixture is exothermic and the interaction forces acting between the CTAC and MFH species are hydrophobic, ion–dipole, and electrostatic interactions. The transfer properties and enthalpy–entropy compensation were also assessed and described comprehensively.
