Pyrimidine Thioethers: A Novel Class of HIV-1 Reverse Transcriptase Inhibitors with Activity Against BHAP-Resistant HIV
摘要:
A series of pyrimidine thioethers was synthesized and evaluated for inhibitory properties against wild-type HIV-1 reverse transcriptase (RT) and an RT carrying the resistance-conferring mutation P236L. Modifications of both the pyrimidine and the functionality attached through the thioether yielded several analogues, which demonstrated activity against both enzyme types, with IC50 values as low as 190 nM against wild-type and 66 nM against P236L RT. Evaluation of a select number of pyrimidine thioethers in cell culture showed that these compounds have excellent activity against HIV-1(IIIB)-WT and retain good activity against a laboratory-derived HIV-1(MF) delavirdine-resistant variant.
Exploring the Scope for Scale-Up of Organic Chemistry Using a Large Batch Microwave Reactor
摘要:
A new batch microwave reactor has been evaluated in the context of palladium-mediated transformations, condensation reactions, nucleophilic aromatic substitution reactions, and alkylations. Importantly, a linear scaling approach was taken, no changes being made to the protocol when moving from the small, developmental scale to larger scales. In some cases reactions were scaled over 18,000-fold when moving from small (0.1-1 nmol) to large (1-18 mol) runs.

2-Substituted 4-arylamino-6-methylpyrimidines were synthesized by stepwise modification of the structure of 6-methyl-2-thiouracyl through the intermediate 2-(ar)alkylthio-6-methyl-4-chloropyrimidines. Some of the compounds synthesized exhibit expressed antimycobacterial activity.
