were synthesized specifically as prodrugs, including benzoylcyanamide (2), pivaloylcyanamide (3), and 1-adamantoylcyanamide (4), as well as long- and medium-chain fatty acyl derivatives such as palmitoyl- (6), stearoyl- (7), and n-butyrylcyanamide (5). N-Protected alpha-aminoacyl and peptidyl derivatives of cyanamide were also synthesized, and these include N-carbobenzoxyglycyl- (10), hippuryl- (13)
氰胺(H2NC与N相同)是一种有效的醛脱氢酶(AlDH)抑制剂,在治疗上用作一种醇类威慑剂,已知会以乙酰氰胺的形式快速代谢并排泄到尿液中(1)。根据我们的观察结果,即1在体内被脱乙酰基化为氰胺,尽管非常轻微,从而作为后者的前药形式的前体,专门合成了几种氰胺的酰基衍生物作为前药,包括苯甲酰基氰酰胺(2),新戊酰氰胺( 3),1-金刚烷基氨酰胺(4),以及长链和中链脂肪酰基衍生物,例如棕榈酰-(6),硬脂酰基-(7)和正丁酰氰胺(5)。还合成了N-保护的氰酰胺的α-氨基酰基和肽基衍生物,包括N-碳苯甲氧基甘氨酰-(10),马尿酰基-(13),N-苯甲酰基-L-亮氨酸-(14),N-碳苯甲氧基氧基-L-亮氨酰-(18),N-碳苯甲氧基-L-焦谷氨酰-(22),L-焦谷氨酰基-L-亮氨酰-(19)和L-焦谷氨酰基-L-苯丙氨酰氰胺(20)。腹膜内给药后3小时,所有这些氰胺前药在大鼠体内均显着提高了
