Abstract

Several N-methyl-N″-alkylguanidinium derivatives were synthesized and used as simplified analogues of niphimycin (NM), a guanidylpolyol macrolide, in structure–activity relationship studies. The C16-alkylated derivative exerted fungicidal activity by directly damaging the fungal plasma membrane and inducing oxidative stress in a manner similar to niphimycin. These results indicate that the N-methyl-N″-alkylguanidinium moiety is required for antifungal activity by NM.
