Cryptophycins

Webcryptophycins can be divided into the four building blocks unit A–D being amino or hydroxycarboxylic acids, respectively. Unit A is an α,β-unsaturated δ-hydroxy carboxylic acid typical for cryptophycins. In cryptophycin-1, this building block contains a benzylic β-epoxide, while many cryptophycin derivatives isolated WebThe cryptophycins appear to be additive with fractionated radiation therapy in the human H460 non-small cell lung carcinoma. In the human HCT116 colon carcinoma, the cryptophycins resulted in a greater than additive tumor response when administered sequentially with 5-fluorouracil or irinotecan.
