Biological Activity for (S)-(+)-Dimethindene maleate

(S)-(+)-Dimethindene maleate is an enantiomer that is a subtype-selective M2 muscarinic receptor antagonist (pKi values are 7.08, 7.78, 6.70 and 7.00 for M1, M2, M3 and M4 receptors respectively). Also H1 histamine receptor antagonist (pKi = 7.48). Allows formation of extended pluripotent stem (EPS) cells in combination with CHIR 99021 (Cat.No. 4423), minocycline hydrochloride (Cat.No. 3268) and human leukemia inhibitory factor.

For more information about how Dimethindene maleate may be used, see our protocol: Generation and Propagation of EPS cells (LCDM Cocktail).
