WebOct 17, 1997 · Total Synthesis of Cryptophycins-1, -3, -4, -24 (Arenastatin A), and -29, Cytotoxic Depsipeptides from Cyanobacteria of the Nostocaceae. The Journal of Organic Chemistry 1999, 64 (17) , 6206-6216. WebOct 20, 2009 · Cryptophycins are a family of highly cytotoxic, cyclic depsipeptides. They display antitumour activity that is largely maintained for multi-drug-resistant tumour cells. Cryptophycins are composed of four building blocks (units A–D) that correspond to the respective amino and hydroxy acids.

WebCryptophycin styrenes 7 and β-epoxides 6, bearing diverse side chains in fragment “B”, were evaluated for cytotoxic activity. β-Epoxides 6, in general, were significantly more potent than the corresponding α-epoxides 17 and styrenes 7. Web本发明涉及her2阳性乳腺癌的辅助治疗。提供了人患者中的可手术的her2阳性原发性乳腺癌的辅助治疗的方法,其通过在化疗和曲妥珠单抗以外还施用帕妥珠单抗。与在没有帕妥珠单抗的情况下施用曲妥珠单抗和化疗相比,该方法为诊断有her2阳性早期乳腺癌(ebc)的患者降低侵入性乳腺癌复发或死亡的风险。 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 depsipeptide family. 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 subsequently identified as See more Cryptophycins are potent microtubule inhibitors, with a mechanism of action similar to that of vinca alkaloids. Treatment of cells with cryptophycins depletes … See more Cryptophycins were first isolated from cyanobacteria but have subsequently been produced by chemical synthesis. Chemoenzymatic syntheses have also been reported. See more Members of the cryptophycin family have been studied as anti-tumor agents.
