Methenol DM1 is a tubulin inhibitor that binds to the end of microtubules and inhibits microtubule dynamics. N2'-deacetyl-N2'-(3-Mercapto-1-oxopropyl)-Maytansine can be synthesized by multi-step reactions with 2 steps: First: 32%/dicyclohexylcarbodiimide; ZnCl2/CH2Cl2; diethyl ether/2h/20 °C; Second: 76% dithiothreitol; EDTA/methanol; ethyl acetate; aq. phosphate buffer/3h/pH 7.5.

Yield:139504-50-0 4.1 g

Reaction Conditions:

with 1,4-dithio-L-threitol in methanol;ethyl acetate at 20; for 3.5 h;Inert atmosphere;

Steps:

1.4 Step (4)
The crude compound DM1-3L (5g) and DL-dithiothreitol (5.1g) were mixed and dissolved with ethyl acetate (120ml) and methanol (120ml), and phosphate buffer (120mM, pH=7.5, 120ml) was added, Under argon protection, react at room temperature for 3.5 hours, add phosphate buffer (pH=6.0, 240ml), extract with ethyl acetate, wash the organic phase with water, concentrate under reduced pressure to dryness, and separate by column chromatography to obtain compound DM1 (4.1g) ).
