Maytansinol inhibits microtubule assembly and induces microtubule disassembly in vitro. Maytansinol disrupts the mitotic spindle and prevents mitotic exit in Drosophila. Maytansinol is used in the preparation of site-specific trastuzumab maytansinoid antibody-drug conjugates with improved therapeutic activity.Product Details:Name: MaytansinolCAS#: 57103-68-1Chemical Formula: C28H37ClN2O8Exact Mass: 564.2238Molecular Weight: 565.06Elemental Analysis: C, 59.52; H, 6.60; Cl, 6.27; N, 4.96; O, 22.65Specification:Related CAS #: 57103-68-1? ??Synonym: Maytansinol; Ansamitocin P-0; Ansamitocin P 0; Antibiotic C 15003P 0; NSC 239386; NSC-239386; NSC239386; maytansine derivative;IUPAC/Chemical Name: (14S,16S,32S,33S,2R,4S,10E,12E,14R)-86-chloro-14,4-dihydroxy-85,14-dimethoxy-33,2,7,10-tetramethyl-7-aza-1(6,4)-oxazinana-3(2,3)-oxirana-8(1,3)-benzenacyclotetradecaphane-10,12-diene-12,6-dioneInChi Key: QWPXBEHQFHACTK-RZKXNLMUSA-NInChi Code: InChI=1S/C28H37ClN2O8/c1-15-8-7-9-22(37-6)28(35)14-20(38-26(34)30-28)16(2)25-27(3,39-25)21(32)13-23(33)31(4)18-11-17(10-15)12-19(36-5)24(18)29/h7-9,11-12,16,20-22,25,32,35H,10,13-14H2,1-6H3,(H,30,34)/b9-7+,15-8+/t16-,20+,21+,22-,25+,27+,28+/m1/s1SMILES Code: O=C1O[C@@]([C@@H](C)[C@H]2[C@](C)([C@@H](O)CC3=O)O2)([H])C[C@@]([C@H](OC)/C=C/C=C(CC4=CC(OC)=C(Cl)C(N3C)=C4)\C)(O)N1Appearance: Solid powderPurity: >98% (or refer to the Certificate of Analysis)Shipping Condition: Shipped under ambient temperature as non-hazardous chemical.
