Maytansinoid DM4, a naturally occuring maytansine analogue, is a highly potent/cytotoxic antitubulin agent with anticancer properties. Maytansinoids have been shown to be able to disrupt microtubule function. Maytansinoid DM4 can be used for the preparation of antibody drug conjugates such as Anetumab ravtansine (BAY 94-9343) and Indatuximab ravtansine (BT062).

Biological Activity
| ln Vitro | A novel thiol-containing powerful maytansinoid is DM4, a structural analogue of maytansine. A cytotoxic maytansinoid medication is DM4. It is synthesized to form disulfide bonds between maytansinoids and antibodies. Maytansinoids potently suppress microtubule dynamics, causing a mitotic block and consequent apoptotic cell death. They do this by inhibiting tubulin polymerization and microtubule assembly and by enhancing microtubule destabilization[1]. |

| Additional Infomation |
Ravtansine is an organic molecular entity. Ravtansine is a tubulin-binding maytansinoid. Ravtansine binds to tubulin at the maytansine-binding site, which disrupts microtubule assembly/disassembly dynamics and inhibits mitosis. An ansa macrolide isolated from the MAYTENUS genus of East African shrubs. See also: Maytansine (annotation moved to). |
Solubility Data

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (3.20 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (3.20 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly..
