A synthetic route to 2-O-(diphenylacetyl)salicylic acid derivatives was developed and the effects of the products on the heat-denaturation of albumin and on heat-induced erythrocytolysis were examined (in vitro anti-inflammation test). Trichloroethyl salicylate was acylated with diphenylacetic acid and its derivatives in the presence of methanesulfonyl chloride and pyridine, and the products were deprotected with zinc-acetic acid to give 2-O-(diphenylacetyl)salicylic acid derivatives. Their biological effects resembled those of ibuprofen.
开发了一条合成2-O-(二苯乙酰基)水杨酸衍生物的路线,并考察了产品对白蛋白热变性及热致红细胞溶血的影响(体外抗炎试验)。水杨酸三氯乙酯在甲磺酰氯和吡啶存在下与二苯乙酸及其衍生物进行酰化反应,产物用乙酸锌脱保护得到2-O-(二苯乙酰基)水杨酸衍生物。它们的生物效应与布洛芬相似。
