WebCryptophycin-309 (C-309) is a glycinate ester of the chlorohydrin Cryptophycin-296. The glycinate derivative provided both chemical stability and improved aqueous solubility. After the examination of 81 different Cryptophycin analogs in tumor bearing animals, C-309 has emerged as superior to all others. WebCryptophycins were found to induce apoptosis due to inhibition of the microtubule dynamics. Consequently, cryptophycin analogues are considered as potential antitumour agents. Retrosynthetically, cryptophycins can be subdivided into four building blocks, namely units A–D, to be assembled in the total synthesis.
