Practical access to four stereoisomers of naftidrofuryl and their binding affinity towards 5-hydroxytryptamine 2A receptor
摘要:
Naftidrofuryl oxalate (Praxilene (R), 1) has been used for the treatment of intermittent claudication for more than 30 years. It selectively blocks vascular and platelet 5-hydroxytryptamine 2 (2-HT2) receptors. This drug is marketed as a mixture of four stereoisomers, and so far there is no individual biological evaluation on the single isomers. The purpose of this study is to provide an improved method for the preparation of all four stereoisomers of naftidrofuryl, and more importantly, to distinguish them in terms of their binding affinity to 5-hydroxytryptamine 2A (5-HT2A) receptor. The bioassay results revealed that the C-2S configuration of naftidrofuryl was crucial for the binding affinity with 5-HT2A receptor, and the C-2' configuration was less important for binding. In conclusion, our study may pave the way to develop single naftidrofuryl isomers with C-2S configuration as inhibitors of 5-HT2A receptor that have clinical significance as vasodilators and CNS agents.

The development of selective CB2 receptor agonists is a promising therapeutic approach for the treatment of inflammatory diseases, without CB1 receptor mediated psychoactive side effects. Preliminary structure-activity relationship studies on pyrazoylidene benzamideagonists revealed the -ylidene benzamide moiety was crucial for functional activity at the CB2 receptor.
