SAR3419

anti-CD19-DM4 immunoconjugate SAR3419 is an immunoconjugate consisting of an anti-CD19 monoclonal antibody conjugated to the maytansinoid DM4, a derivative of the cytotoxic agent maytansine (DM1), with potential antineoplastic activity. Anti-CD19-DM4 conjugate SAR3419 targets the cell surface antigen CD19, found on a number of B-cell-derived cancers. Upon antibody/antigen binding and internalization, the immunoconjugate releases DM4, which binds to tubulin and disrupts microtubule assembly/disassembly dynamics, resulting in inhibition of cell division and cell growth of CD19-expressing tumor cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

About maytansine: maytansine is an ansamycin antibiotic originally isolated from the Ethiopian shrub Maytenus serrata. Maytansine binds to tubulin at the rhizoxin binding site, thereby inhibiting microtubule assembly, inducing microtubule disassembly, and disrupting mitosis. Maytansine exhibits cytotoxicity against many tumor cell lines and may inhibit tumor growth in vivo. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus). The chemical name of maytansine is L-alanine, N-acetyl-N-methyl-, 11-chloro-21-hydroxy-12,20-dimethoxy-2,5,9,16-tetramethyl-8,23-dioxo-4,24-dioxa-9,22-diazatetracyclo[19.3.1.110,14.03, 5]hexacosa-10,12,14(26),16,18-pentaen-6-yl ester, [1S-(1R*,2S*,3R*,5R*,6R*,16E,18E,20S*,21R*)].
