white crystals were obtained from methanol and water, with melting points of 220-225 ° C. And melting points of 204-209.5 ° C., which turned black at> 150 ° C., respectively. UV maximum absorption (pH 7 water):282nm(E 8000); (pH 11 water):283nm(E 7970); (Ph 2 water):273nm (initially Δ50, 7570, after 3143 H).
each was prepared by a fermentation method, and the selected medium was implanted into a water-soluble nutrient solution and incubated under aseptic conditions to obtain pentostatin.
developed by Parke Davis, Inc., launched in 1991. It is an adenosine deaminase (ADA) inhibitor. For hairy cell leukemia in response to alpha-interferon therapy.
