Prostaglandin-H synthase inhibition by malonamides. Ring-opened analogs of phenylbutazone
摘要:
Recent reports of serious concern regarding the safe clinical use of phenylbutazone and its hydroxylated metabolite (oxyphenbutazone) as antiinflammatory agents have prompted the further investigation of ring-opened (malonamide) derivatives as potentially preferable therapeutic derivatives. Earlier reports have claimed reduced toxicity among similar derivatives. These studies reveal the relative degree of prostaglandin-H (PGH) synthase inhibitory activity among a series of malonamide derivatives. Contrary to observations in the pyrazolidinedione series, incorporation of a nonpolar butyl side chain in these malonamides was not beneficial but, rather, detrimental to enzyme-inhibitory activity. Although none of the reported nonbutylated malonamides was as potent an inhibitor of this enzyme as phenylbutazone, they all showed some inhibitory activity. PGH synthase inhibitory activity was especially pronounced in the bis(p-hydroxy anilide) derivatives, even extending to succinamide and adipamide derivatives. Of some interest is the observation that all of these p-hydroxy anilide derivatives were more potent inhibitors of this enzyme than acetaminophen.

The present invention is directed to substituted 2-arylmethylene-N-aryl-N′-aryl-malonamides and analogs thereof. The present invention also relates to the discovery that the compounds are activators of caspases and inducers of apoptosis. Therefore, the activators os caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
