Synthesis and biological activity of N-(aminoiminomethyl)-1H-indole carboxamide derivatives as Na+/H+ exchanger inhibitors

Article abstract of DOI:10.1248/cpb.47.1538

A series of N-(aminoiminomethyl)-1H-indole carboxamide derivatives were synthesized and their inhibitory potencies against the Na⁺/H⁺ exchanger were measured. Variation of the carbonylguanidine group at the 2- to 7- position of the indole ring system showed that a substitution at the 2- position improved the Na⁺/H⁺ exchanger inhibitory activity the most in vitro. This led to the synthesis and evaluation of an extensive series of N- (aminoiminomethyl)-1H-indole-2-carboxamide derivatives. Derivatives having an alkyl or substituted alkyl group at the 1-position of the indole ring system showed higher levels of in vitro activities. N-(aminoiminomethyl)-1-(2- phenylethyl)-1H-indole-2-carboxamide (49) had the strongest activity.
