Development of Dual-Acting Agents for Thromboxane Receptor Antagonism and Thromboxane Synthase Inhibition. 3. Synthesis and Biological Activities of Oxazolecarboxamide-Substituted ω-Phenyl-ω-(3-pyridyl)alkenoic Acid Derivatives and Related Compounds
摘要:
A novel series of oxazolecarboxamide-substituted omega-phenyl-omega-(3-pyridyl)alkenoic acid derivatives was discovered as potent dual-acting agents to block the TXA(2) receptor and to inhibit the thromboxane synthase (TRA/TSI). Synthesis, structure-activity relationship (SAR), and in vitro and in vivo pharmacology of this series of compounds are described. Modification of the series revolved around the oxazole moiety to increase the hydrophilicity of the compounds and to correlate the biological activity with lipophilicity of the compounds. The most potent in the series was (E)-7-[4-[4-[[(4-cyclohexylbutyl)amino]carbonyl]-2-oxazolyl]phenyl]-7-(3-pyridyl)hept-6-enoic acid (14) with K-d = 9.9 +/- 0.4 nM for the thromboxane receptor antagonism and IC50 = 55.0 +/- 17.9 nM for thromboxane synthase inhibition. The compound 14 was a selective TRA/TSI which exhibited desirable characteristics for oral activity, "shunt" effect to elevate PGI(2) level, and absence of agonist activity.
