Particularly, a great amount of natural active molecules have been reported to possess promising therapeutic effects on inflammatory diseases, including asthma, rheumatoid arthritis, hepatitis, enteritis, metabolic disorders and neurodegenerative diseases. However, these natural active molecules with various molecular structures usually exert anti-inflammatory effects through diversiform pharmacological mechanisms, which is necessary to be summarized systematically. In this review, we introduced the current major anti-inflammatory natural active molecules based on their chemical structures, and discussed their pharmacological mechanisms including anti-inflammatory molecular signaling pathways and potential target proteins, which providing a referential significance on the development of novel anti-inflammatory drugs, and also revealing new therapeutic strategies for inflammatory diseases.展开更多

A “deuterated” drug is a drug in which the hydrogen atom in one or more of the carbon-hydrogen bonds in its chemical structure is replaced by deuterium (“heavy hydrogen”, a hydrogen isotope that has a neutron, i.e., one neutron instead of the usual no neutrons). A carbon-deuterium (C-D) bond is more stable in the body than a carbon-hydrogen (C-H) bond. If the deuterium is strategically located in a drug’s chemical structure, the extra stability of the bond will be more resistant to metabolic breakdown, and the duration of drug action will be prolonged. We review the general concept of deuterated drugs, historical examples of the classes of application, and the new approval.展开更多
