Maytansinoids
|
S-methyl DM1 is the primary cellular or liver metabolite of antibody-maytansinoid conjugates prepared with thiol-containing maytansinoids DM1.
The half-maximal concentration for inhibition of microtubule assembly for for S-methyl DM1 is 4 μM. At 100 nM S-methyl-DM1 (84%) suppresses dynamic instability more strongly than Maytansine (45%). Tritiated S-methyl-DM1 bound to 37 high-affinity sites per microtubule (K
d
of 0.1 μM).
The concentration dependence curves for the inhibition of cell proliferation by S-methyl DM1 is sigmoidal in shape in MCF7 cells. Minimal inhibition occurred at 200 pM S-methyl DM1, and inhibition is maximal at 3 nM. S-methyl DM1 (IC
50
of 330 pM) is slightly more potent than Maytansine (IC
50
of 710 pM).
S-methyl DM1 induces maxima of 80% accumulation of cells in G2/M as compared with only 30% in controls in MCF7 cells.
