An array of six pyridyl-substituted fused bicyclic piperidines was prepared as novel cores for medicinal chemistry. For maximum diversity, the size of the fused ring varied from three to six atoms and contained up to two oxygen atoms. The pyridine ring was incorporated to improve physicochemical properties and to challenge the robustness of the chemistry. The presence of the pyridine did interfere with our initial approaches to these molecules, and in several instances, a blocking strategy had to be employed. These new scaffolds possess high sp3 character and may prove useful in multiple medicinal chemistry applications.

Replacement of the amide functionality in IM491 (N-hydroxy-(5S,6S)-1- methyl-6-{[4-(2-methyl-4-quinolinylmethoxy)anilinyl]carbonyl} -5-piperidinecarboxamide) with a sulfonyl group led to a new series of α,β-cyclic and β,β-cyclic γ-sulfonyl hydroxamic acids, which were potent TNF-α converting enzyme (TACE) inhibitors. Among them, inhibitor 4b (N-hydroxy-(4S,5S)-1-methyl-5-{[4-(2-methyl-4- quinolinylmethoxy)phenyl]sulfonylmethyl}-4-pyrrolidinecarboxamide) exhibited IC50 values of 1 nM and 180 nM in porcine TACE (pTACE) and cell assays, respectively, with excellent selectivity over MMP-1, -2, -9 and -13 and was orally bioavailable with an F value of 46% in mice.
