Girinimbine, a carbazole alkaloid has drawn an attention due to its wide range of pharmacological effects such as antiplatelet, antibacterial and anticancer activities. Five new derivatives of girinimbine were successfully semi-synthesized via modification on N-terminal of naturally isolated girinimbine. N-Benzylgirinimbine, N-butylgirinimbine and N-isopentylgirinimbine were obtained from alkylation reaction,whereas, N-butyrylgirinimbine and N- methylbutyrylgirinimbine were obtained from acylation reaction.The structures of synthesized girinimbine derivatives were confirmed by spectroscopic techniques.
