Nα-(tert-Butyloxycarbonyl)peptide p-guanidinophenyl esters were synthesized by amidination of Nα-(tert-butyloxycarbonyl)peptide p-aminophenyl esters with 1-[N, N'-bis(benzyloxycarbonyl)amidino]pyrazole, followed by deprotection by catalytic hydrogenation, in good total yields. These synthetic esters were characterized as specific substrates for trypsin, and kinetic parameters for the trypsin-catalyzed hydrolysis are presented.
Nα-(叔丁氧羰基)肽p-氨基苯酯通过Nα-(叔丁氧羰基)肽p-氨基苯酯与1-[N, N'-二(苄氧羰基)氨基]吡唑进行酰胺化合成,随后通过催化氢化去保护,获得了良好的总体产率。这些合成的酯被表征为酶胰蛋白酶的特定底物,并提供了胰蛋白酶催化水解的动力学参数。
