Biochem./physiol. Wirkung

(S)-(+)-Dimethindene maleate is an antagonist of muscarinic M2 and histamine H1 receptors, recently used as part of part of four-component chemical cocktail shown to convert pluripotent stem cells (PSCs) into extended pluripotent stem (EPS). (S)-(+)-Dimethindene is up to 40-fold more potent than the (R)-(-) enantiomer, with pKi values of 7.78 for M2, and lower affinities for M1, M3 and M4 (7.08, 6.7 and 7.0, respectively). (S)-(+)-Dimethindene has lower affinity for H1 than (R)-(-)- Dimethindene, with pA2 values of 7.48 vs. 9.42, respectively.

The present study was designed to determine to determine the in vitro affinity profile of (R)-(-)-dimethindene and (S)-(+)-dimethindene at muscarinic receptor subtypes using both functional and binding assays. In addition, the racemate was investigated in functional studies. The functional muscarinic

Of all known cultured stem cell types, pluripotent stem cells (PSCs) sit atop the landscape of developmental potency and are characterized by their ability to generate all cell types of an adult organism. However, PSCs show limited contribution to the
