THIOCHROME Usage And Synthesis

Uses

Thiochrome is a selective M4 muscarinic receptor enhancer of acetylcholine affinity.

Purification Methods

Crystallise thiochrome from chloroform. The monohydrochloride has m 235-236o(dec) (from EtOH) and the dihydrochloride has m 237o(dec). [Beilstein 27 III/IV 9599.]
