Novel Substituted Aminoalkylguanidines as Potential Antihyperglycemic and Food Intake-Reducing Agents
摘要:
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.

carbamate-protected guanidines with various alkyl halides and mesylates is described. This protocol proceeds via deprotonation of the acidic N-carbamate hydrogen of the guanidine under biphasic conditions using a catalytic amount of a tetrabutylammonium salt as a phase-transfer catalyst. In this manner, highly functionalizedguanidines can be obtained. The reaction is tolerant of a wide range of functional groups
