Biological Activity

DM4 has anticancer properties of maytansinoids due to their ability to disrupt microtubule function. Maytansinoid DM4 can be use to make antibody drug conjugates such as Anetumab ravtansine (BAY 94-9343) and Indatuximab ravtansine (BT062). Maytansinoids inhibit tubulin polymerization and microtubule assembly and enhance microtubule destabilization, so there is potent suppression of microtubule dynamics resulting in a mitotic block and subsequent apoptotic cell death.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Batabulin sodium

Batabulin (T138067) sodium is a synthetic pentafluorophenylsulfonamide with potential antineoplastic activity, covalently binds to and selectively modifies the beta 1, beta 2, beta 3, and beta 4 isotypes of beta tubulin at a conserved cysteine residue, resulting in disruption of microtubule polymerization, collapse of the cytoskeleton, an increase in chromosomal ploidy, cell cycle arrest, and tumor cell apoptosis.
