Light activated acyl-enzymes of the formula: ##STR1## are disclosed. In the compounds of Formula (III), ENZ is an enzyme, X is O or S, Y is --NR.sub.3 R.sub.4, --OR.sub.5, or --SR.sub.5, and Z is a nucleophile. m is 0 to 3 and n is 1 or 2. Y is substituted on the ring at either or both of the 4 and 6 position. R.sub.1 and R.sub.2 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. R.sub.3 and R.sub.4 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl, except that R.sub.3 and R.sub.4 are not simultaneously both H. R.sub.5 is C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. Methods of using the acyl-enzymes and intermediates for making the acyl-enzymes are disclosed. A preferred intermediate is 2-Propenoic acid, 3-(2-hydroxy-4-diethylaminophenyl)-2-methyl-,4-(aminoiminomethyl)phenyl ester,(E)-, monohydrochloride salt, which is preferably reacted with thrombin to form an acyl-thrombin.
本发明公开了化学式为:##STR1## 的光敏活化酰基酶。在化合物中,公式(III)中,ENZ是酶,X是O或S,Y是--NR.sub.3 R.sub.4,--OR.sub.5或--SR.sub.5,Z是亲核试剂。m为0到3,n为1或2。Y在环上的4和6位置中的任一或两个位置被取代。R.sub.1和R.sub.2各自独立地是H、C1到C4烷基、C3到C4非共轭烯烃或C3到C4非共轭炔烃。R.sub.3和R.sub.4各自独立地是H、C1到C4烷基、C3到C4非共轭烯烃或C3到C4非共轭炔烃,但R.sub.3和R.sub.4不同时为H。R.sub.5是C1到C4烷基、C3到C4非共轭烯烃或C3到C4非共轭炔烃。公开了使用酰基酶和制备酰基酶的中间体的方法。首选中间体是2-丙烯酸,3-(2-羟基-4-二乙基氨基苯基)-2-甲基-,4-(氨基亚甲基)苯酯,(E)-,单盐酸盐,最好与凝血酶反应形成酰基凝血酶。
