Anti-AIDS agents 72. Bioisosteres (7-carbon-DCKs) of the potent anti-HIV lead DCK
摘要:
Three 9, 10-di- O-(-)-camphanoyl-7,8,9, 10-tetrahyd to -benzo [h]chromen-2- one (7-carbon-DCK) analogs (3a-C) were synthesized and evaluated for inhibition of HIV-1 replication in H9 lymphocytes. All three new carbon bioisosteres of the anti-HIV lead DCK showed anti-HIV activity. Compound 3a had an EC50 value of 0.068 pM, which was comparable to that of DCK in the same assay. The preliminary results indicated that 7-carbon-DCK analogs merit attention as potential HIV-1 inhibitors for further development into clinical trials candidates. (c) 2007 Elsevier Ltd.

out under mild conditions in the presence of N-tosyl-l-threonine (NTsLT) as an acidic additive using chloramine T trihydrate, 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) or N-bromoacetamide (AcNHBr) as the halogen source, respectively, affording the corresponding vicinal halohydrins in good to high yields with excellent regio- and stereoselectivities.
