It exhibited higher activity against rodent tumors than indirubin itself. Experiments have shown the improved absorption of meisoindigo, compared to indirubin to be one of the major reasons for the enhancement of antitumor activity. Studies on the mechanism of meisoindigo action indicate that it strongly inhibits DNA biosynthesis in tumor cells. Strong inhibition of the drug on assembly of microtubule protein was also obtained. By means of FCM technique the effects of meisoindigo on mouse leukemia L1210 cell cycle were examined. Experimental results showed that under the action of meisoindigo the S phase cells accumulated and the traverse of the cells in G2 + M phase to G1 phase may also be blocked to some extent.展开更多

Experimental results showed that under the action of meisoindigo the S phase cells accumulated and the traverse of the cells in G2 + M phase to G1 phase may also be blocked to some extent.
文摘Nagilactones are tetracyclic natural products isolated from various Podocarpus species.These lactone-based compounds display a range of pharmacological effects,including antifungal,anti-atherosclerosis,anti-inflammatory and anticancer activities reviewed here.The most active derivatives,such as nagilactones C,E and F,exhibit potent anticancer activities against different cancer cell lines and tumor models.A comprehensive analysis of their mechanism of action indicates that their anticancer activity mainly derives from three complementary action:(i)a drug-induced inhibition of cell proliferation coupled with a cell cycle perturbation and induction of apoptosis,(ii)a blockade of the epithelial to mesenchymal cell transi-tion contributing to an inhibition of cancer cell migration and invasion and(iii)a capacity to modulate the PD-L1 immune checkpoint.Different molecular effectors have been implicated in the antitumor activity,chiefly the AP-1 pathway blocked upon activation of the JNK/c-Jun axis.Nag-C is a potent inhibitor of protein synthesis binding to eukaryotic ribosomes and inhibition of different protein kinases,such as RIOK2 and JAK2,has been postulated with Nag-E.The literature survey on nagilactones highlights the therapeutic potential of these little-known terpenoids.The mechanistic analysis also provides useful information for structurally related compounds(podolactones,oidiolactones,inumakilactones)isolated from Podo-carpus plants.

文摘Biflavonoids are divided in two classes:C-C type compounds represented by the dimeric compound amentoflavone and C-O-C-type compounds typified by hinokiflavone(HNK)with an ether linkage between the two connected apigenin units.This later sub-group of bisflavonyl ethers includes HNK,ochnaflavone,delicaflavone and a few other dimeric compounds,found in a variety of plants,notably Selaginella species.A comprehensive review of the anticancer properties and mechanism of action of HNK is provided,to highlight the anti-proliferative and anti-metastatic activities of HNK and derivatives,and HNK-containing plant extracts.The anticancer effects rely on the capacity of HNK to interfere with the ERK1-2/p38/NFκB signaling pathway and the regulation of the expression of the matrix metalloproteinases MMP-2 and MMP-9(with a potential direct binding to MMP-9).In addition,HNK was found to function as a potent modulator of pre-mRNA splicing,inhibit-ing the SUMO-specific protease SENP1.As such,HNK represents a rare SENP1 inhibitor of natural origin and a scaffold to design synthetic compounds.Oral formulations of HNK have been elaborated to enhance its solubility,to facilitate the compound delivery and to enhance its anticancer efficacy.The review shed light on the anticancer potential of C-O-C-type biflavonoids and specifically on the pharmacological profile of HNK.This compound deserves further attention as a regu-lator of pre-mRNA splicing,useful to treat cancers(in particular hepatocellular carcinoma)and other human pathologies.
