with tetralin or an oxygen-containing heterocyclic compound as a N alpha-substituent showed an inhibition with an I50 less than 10(-5) M. N-Monosubstituted derivatives of N alpha-dansyl-L-arginine amide were not hydrolyzed at all by thrombin and were hydrolyzed very slowly by trypsin, and N,N-disubstituted derivatives were not hydrolyzed at all by both enzymes.
制备了一系列具有取代或未取代的萘和杂环化合物作为Nα取代基的Nα-(芳基磺酰基)-L-精氨酸酰胺衍生物,并测试了它们作为凝血酶凝血活性的抑制剂。Nα-丹磺酰基-L-精氨酸酰胺的Nn-丁基和Nn-丁基-N-甲基衍生物对Nα-丹磺酰基-L-精氨酸酰胺的N-烷基和N,N-二烷基衍生物的抑制作用最大。它们的抑制作用与I50为2 X 10(-6)M的Nα-丹磺酰基-L-精氨酸-正丁酯的抑制作用一样。Nα-取代的4-甲基萘他磺酰基-L-精氨酸酰胺衍生物-和4-乙基哌啶也显示出有效的抑制作用,I50为10(-7)至10(-6)M。在该研究中,最有效的抑制作用是1- [Nα-(4,6-二甲氧基萘-2-磺酰基]-精氨酰基] -4-甲基哌啶,I50为7。

Thrombin inhibitors. 3. Carboxyl-containing amide derivatives of N.alpha.-substituted L-arginine
N alpha-(arylsulfonyl)-L-arginine amide derivatives having carboxamide N-substituents with a carboxyl group was prepared and tested as inhibitors of the clotting activity of thrombin. The most inhibitory compounds were obtained when a carboxyl group was introduced into the carbon next to the amide nitrogen of N alpha-(arylsulfonyl)-L-arginine amide derivatives, e.g., N alpha-(arylsulfonyl)-L-arginyl-N-butyl-
制备了一系列具有羧基羧基酰胺N-取代基的Nα-(芳基磺酰基)-L-精氨酸酰胺衍生物,并测试了它们作为凝血酶凝血活性的抑制剂。当在Nα-(芳基磺酰基)-L-精氨酸酰胺衍生物(例如Nα-(芳基磺酰基)-L-精氨酸-N-丁基)的酰胺氮旁的碳原子中引入羧基时,获得最具抑制性的化合物。 -,N-(甲氧基乙基)-或N-(四氢糠基)甘氨酸和4-烷基-1- [Nα-(芳基磺酰基)-L-精氨酰基] -2-哌啶甲酸,I50为1-3 X 10( -7)M.
