Thiophene and bioisostere derivatives as new MMP12 inhibitors.

A new MMP12 inhibitor series has been identified containing a thiophene moiety. Different approaches have been considered to replace this potential toxicophore. α-Fluorothiophene derivatives were the most interesting compounds.

Structure-based design and synthesis of novel non-zinc chelating MMP-12 inhibitors.

A new class of MMP-12 inhibitors was discovered and optimized using structure-based drug design methods. Modeling studies using a known MMP-12 crystal structure identified a new interaction mode for these new MMP-12 inhibitors. Further optimization resulted in the discovery of a compound displaying nanomolar activity against MMP-12 and which was co-crystallized with MMP-12.

4-benzyl- and 4-benzoyl-3-dimethylaminopyridin-2(1H)-ones, a new family of potent anti-HIV agents: optimization and in vitro evaluation against clinically important HIV mutant strains.

The 4-benzyl and 4-benzoyl-3-dimethylaminopyridinones 13 and 14 are representatives of a new class of highly potent non nucleoside type inhibitors of HIV-1 reverse transcriptase. To conduct SAR studies on these two lead compounds, 102 new analogues were prepared. Thirty-three compounds displayed nanomolar range activity in vitro against wild-type HIV-1, and among these, 18 were active against the 103N, Y181C, and Y188L mutant strains with IC50 values inferior to 1 microM.
