Novel substituted aminoalkylguanidines as potential antihyperglycemic and food intake-reducing agents.

We report the synthesis and evaluation of aminoalkylguanidine analogues and derivatives in C57BL/KsJ db/db diabetic mice, following identification by random screening of 1a and 1b as potential antihyperglycemics and/or modulators of food intake. These compounds are related to galegine, a gamma,gamma-dimethylallylguanidine. Between the newly identified compounds, 1h N-(cyclopropylmethyl)- N'-(4-(aminomethyl)cyclohexylmethyl)guanidine showed the most balanced activity as antihyperglycemic and food intake-reducing agent.
