The syntheses of alpha-mono- and alpha-difluoromethyl derivatives of tryptophan and 5-hydroxytryptophan are described. In an attempt to selectively regulate serotonin synthesis, alpha-(mono- and difluoromethyl)tryptophan were tested in vivo as precursors (or prodrugs) of their 5-hydroxy analogues. Although alpha-(mono- and difluoromethyl)-5-hydroxytryptophans are potent irreversible inhibitors of aromatic
描述了色氨酸和5-羟基色氨酸的α-单-和α-二氟甲基衍生物的合成。为了选择性调节5-羟色胺的合成,在体内对α-(单和二氟甲基)色氨酸作为其5-羟基类似物的前体(或前药)进行了测试。尽管α-(单和二氟甲基)-5-羟基色氨酸是芳香族氨基酸脱羧酶的有效不可逆抑制剂(与α-二氟甲基-多巴等效),但只有α-(一氟甲基)色氨酸会影响体内5-羟色胺的水平(降低幅度很小) α-(二氟甲基)色氨酸是活化(或辅助)酶色氨酸羟化酶的非常差的底物。
