A series of nitrate ester analogues of the acetaminophen derivative SCP-1 were prepared by triflic acid catalyzed O-acylation of SCP-1 with chloroalkanoyl chlorides followed by nitration with silver nitrate. The chloroesters and corresponding nitrate esters were obtained in high yields. Preliminary hepatotoxicity studies revealed nitrate esters 5b (MD-38) and 5c (MD-39) to be well tolerated by human
对乙酰氨基酚衍生物SCP-1的一系列硝酸酯类似物的制备是通过三氟乙酸用氯代烷酰氯对SCP-1进行O-酰化,然后用硝酸银硝化来制备的。高产率地获得了氯酯和相应的硝酸酯。初步的肝毒性研究显示,人肝细胞对硝酸酯5b(MD-38)和5c(MD-39)具有很好的耐受性,并且对所测试的三种细胞色素P450酶(CYP3A4,CYP2E1和CYP2D6)的影响很小。另外,硝酸酯5c(MD-39)表现出与对乙酰氨基酚相似的解热活性。
