A series of phenyl-substituted pyrones, pyridines, and pyrimidines bearing a 5-tetrazolyl or N-(5-tetrazolyl) carbamoyl group as an acidic moiety was synthesized. The compounds were tested for antiallergic activity by passive cutaneous anaphylaxis (PCA) assay in rats after oral administration. Among the compounds synthesized. N-(5-tetrazolyl)-6-phenylpyridine-2-carboxamides (53, 54 and 55) were found to display remarkably high potency.

The present invention relates generally to pharmaceutical agents containing a heterocyclic moiety, and in particular, to heterocyclic metalloprotease inhibiting compounds. More particularly, the present invention provides a new class of heterocyclic MMP-3, MMP-8 and/or MMP-13 inhibiting compounds with a squaramide or benzoxazinone moiety, that exhibit an increased potency and selectivity in relation to currently known MMP-13, MMP-8 and MMP-3 inhibitors.

Piperazinyl-glutamate-pyrimidines were prepared with oxygen, nitrogen, and sulfur substitution at the 4-position of the pyrimidine leading to highly potent P2Y(12) antagonists. In particular, 4-substituted piperidine-4-pyrimidines provided compounds with exceptional potency. Pharmacokinetic and physicochemical properties were fine-tuned through modi. cations at the 4-position of the piperidine ring leading to compounds with good human PRP potency, selectivity, clearance and oral bioavailability.
