Structure–activity relationship studies of 1-(4-chloro-2,5-dimethoxyphenyl)-3-(3-propoxypropyl)thiourea, a non-nucleoside reverse transcriptase inhibitor of human immunodeficiency virus type-1
摘要:
The reverse transcriptase (RT) of the human immunodeficiency virus type-1 (HIV-1) is still a prime target for drug development due to the continuing need to block drug-resistant RT mutants by new inhibitors. We have previously identified 1-(4-chloro-2,5-dimethoxyphenyl)-3-(3-propoxypropyl)thiourea, compound 1, as a potent RI inhibitor from an available chemical library. Here, we further modified this compound to study structure activity relationships when replacing various groups in the molecule. Different functional groups were systematically introduced on the aromatic ring and the aliphatic chain of the compound was modified. The effect of these modifications on viral infectivity was then evaluated. The most potent compound found was propyl 4-(amino-N-(4-chloro-2,5-dimethoxyphenyl)methanethioamino)butanoate, 45c, which inhibited infectivity with a calculated IC50 of about 1.1 mu M. Docking studies identified potential important interactions between the top scoring ligands and HIV-1 RT, and the predicted relative affinity of the ligands was found to be in agreement with the experimental results.

Pronounced Catalytic Effect of a Micellar Solution of Sodium Dodecyl Sulfate (SDS) on the Efficient C-S Bond Formation<i>via</i>an Odorless Thia-Michael Addition Reaction through the<i>in situ</i>Generation of<i>S</i>-Alkylisothiouronium Salts
Abstractmagnified imageA pronounced catalytic effect of sodium dodecyl sulfate (SDS) was observed on thein situproduction ofS‐alkylisothiouronium saltsviathe reaction of primary, allyl and benzyl halides with thiourea in SDS droplets .Hydrolysis of the generatedS‐alkylisothiouronium salts in the palisade layer of the droplets produces the corresponding thiol moieties which are immediately added to the electron‐deficient olefins that are present in the micellar core to produce the thia‐Michael adducts. The entire route is an almost odorless process. The yields of the products are good to excellent and the method is applicable to large‐scale operation without any problem.
