CX-659S (1) [(S)-6-amino-5-(6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxamido)-3-methyl-1-phenyl-2,4-(1H,3H)-pyrimidinedione], has been developed as a new type anti-inflammatory agent for the treatment of dermatitis. The structure of a major metabolite of CX-659S was determined as (S)-6-amino-5-[2-hydroxy-2-methyl-4-(2,4,5-trimethyl-3,6-dioxo-1,4-cyclohexadienyl)butanamide]-3-methyl-1-phenyl-2,4-(1H,3H)-pyrimidinedione (2) by direct comparison with the synthesized authentic compound. The anti-inflammatory activity of 2 was equipotent with that of 1 on the contact hypersensitivity reaction (CHR) induced by picryl chloride (PC) in mice, suggesting that compound 2 contributes, at least in part, to the anti-inflammatory activity of CX-659S.
CX-659S (1) [(S)-6-氨基-5-(6-羟基-2,5,7,8-四甲基苯并二氢吡喃-2-甲酰胺基)-3-甲基-1-苯基-2,4-( 1H,3H)-嘧啶二酮]已被开发为治疗皮炎的新型抗炎剂。 CX-659S的主要代谢物的结构被确定为(S)-6-amino-5-[2-羟基-2-甲基-4-(2,4,5-trimethyl-3,6-dioxo-1) ,4-环己二烯基)丁酰胺]-3-甲基-1-苯基-2,4-(1H,3H)-嘧啶二酮(2)通过与合成的真实化合物直接比较。在小鼠体内由苦基氯 (PC) 诱导的接触性超敏反应 (CHR) 中,2 的抗炎活性与 1 的抗炎活性相当,表明化合物 2 至少部分有助于 CX 的抗炎活性-659S。
