Description

CHEMBL558541 belongs to the class of organic compounds known as harmala alkaloids. Harmala alkaloids are compounds with a structure based on harmaline, harmine, harmalol, harman or a derivative of those parents. These parents are beta-carbolines, consisting of a pyrimidine fused to the pyrrole moiety of an indole to form a pyrido[3,4-b]indole. 1-ethyl-8-methoxy-9h-pyrido[3,4-b]indole is found in Picrasma quassioides. CHEMBL558541 is a very strong basic compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as harmala alkaloids. Harmala alkaloids are compounds with a structure based on harmaline, harmine, harmalol, harman or a derivative of those parents. These parents are beta-carbolines, consisting of a pyrimidine fused to the pyrrole moiety of an indole to form a pyrido[3,4-b]indole.
