title: 2'-Chloropentostatin: discovery, fermentation and biological activity.
abstract: 2'-Chloropentostatin (2-CP) is a new nucleoside antibiotic produced by Actinomadura sp. ATCC 39365. A selectively sensitive assay organism, Enterococcus faecalis PD 05045 (MIC 0.005 micrograms/ml) was instrumental in the discovery of this compound. 2-CP is a tight-binding inhibitor of adenosine deaminase (Ki = 1.1 X 10(-10) M).
