We have previously reported that persenone A, isolated from avocado fruit, is an effective inhibitor of both nitric oxide (NO) and superoxide (O2-) generation in cell culture systems. In this study, we have prepared four persenone A-related compounds and examined their inhibition of NO and O2- generation from inflammatory leukocytes. Some structural importance in persenone A to attenuate free radical generation is discussed.
我们以前曾报道过,从鳄梨果实中分离出来的柿内酯 A 是细胞培养系统中一氧化氮(NO)和超氧化物(O2-)生成的有效抑制剂。在本研究中,我们制备了四种柿酮 A 相关化合物,并考察了它们对炎症白细胞产生一氧化氮和一氧化氮-的抑制作用。本文讨论了柿酮 A 在抑制自由基生成方面的一些重要结构。
