2'-Chloropentostatin is a new inhibitor of adenosine deaminase isolated from the fermentation broth of an unidentified actinomycete, ATCC 39365. It contains the aglycone of coformycin, i.e. 3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-o1, coupled to the unusual carbohydrate, 2'-chloro-2'-deoxyribose. 2'-Chloropentostatin is a slightly weaker inhibitor of rat and human adenosine deaminases than coformycin, and considerably weaker than pentostatin. Unlike pentostatin, which appears to undergo a two-stage interaction with adenosine deaminase, 2'-chloropentostatin forms a single enzyme-inhibitor complex. The enzyme-inhibitor complex between adenosine deaminase and 2'-chloropentostatin was much more rapidly dissociable than the complex with pentostatin. |
