WebThis invention concerns methods of treating a patient diagnosed with glioblastoma comprising administering to said patient a therapy comprising an effective amount of an anti-VEGF antibody and a chemotherapeutic. Cryptophycins are potent microtubule inhibitors, with a mechanism of action similar to that of vinca alkaloids. Treatment of cells with cryptophycins depletes microtubules through interaction with tubulin, thereby preventing cell division. Cryptophycins are capable of inducing apoptosis, possibly … See more Cryptophycins are a family of macrolide molecules that are potent cytotoxins and have been studied for potential antiproliferative properties useful in developing chemotherapy. They are members of the See more Cryptophycins were originally discovered in 1990 in cyanobacteria of the genus Nostoc. Cryptophycins were patented as antifungal agents with an unknown mechanism of action and … See more Cryptophycins were first isolated from cyanobacteria but have subsequently been produced by chemical synthesis.

WebCryptophycin is a potent antitumor agent that depletes microtubules in intact cells, including cells with the multidrug resistance phenotype. To determine the mechanism of action of cryptophycin, its effects on tubulin function in vitro were analyzed. Cryptophycin reduced the in vitro polymerization of bovine brain microtubules by 50% at a drug:tubulin ratio of 0.1.
