Cryptophycin 中文
WebA highly convergent synthesis of cryptophycins in their enantiomerically-pure forms was achieved. Our strategy consists of the synthesis of the two units 3 and 4 and linking them together to form the macrocyclic ring. The upper unit 3 was prepared from 10 in four steps, and the lower unit 4 was prepared from 20 in three steps. Enantioselective biocatalytic … WebApr 8, 2005 · Abstract. Cryptophycin is a promising drug in many cancer therapies. Unfortunately, cryptophycin is expensive to produce synthetically because of its complex structure; however, certain strains of micro-algae naturally produce cryptophycin. This work studies the production of cryptophycin from two strains of Nostoc sp., ATCC 53789 and …
