Most drugs used to treat pain and inflammation act through inhibition of the enzymes prostaglandin G/H synthase, commonly known as cyclooxygenase (COX). Among these, the simultaneous inhibition of cyclooxygenase 1 (COX-1) would explain the unwanted side effects in the gastrointestinal tract and many adverse cardiovascular effects, such as high blood pressure, myocardial infarction and thrombosis. These side effects led in time to the development of NSAIDs that behave as selective COX-2 inhibitors. This manuscript highlights the structure-activity relationships which characterize the chemical scaffolds endowed with selective COX-2 inhibition. Additionally, the role of COX-2 inhibitors in the pain phenomenon and cancer is discussed.
大多数用于治疗疼痛和炎症的药物通过抑制前列腺素G/H合酶(通常称为环氧化酶(COX))发挥作用。其中,同时抑制环氧化酶1(COX-1)会导致胃肠道出现不良副作用以及许多不良心血管效应,如高血压、心肌梗死和血栓形成。这些副作用促使了非甾体抗炎药(NSAIDs)的发展,这类药物表现为选择性COX-2抑制剂。本手稿重点介绍了具有选择性COX-2抑制作用的化学支架所具有的构效关系。此外,还讨论了COX-2抑制剂在疼痛现象和癌症中的作用。
