Abstract

Heliotropamide (1), a new alkaloid with a novel oxopyrrolidine-3-carboxamide central moiety, has been isolated as the major product of the dicholoromethane extract of Heliotropium ovalifolium aerial parts. Its structure was elucidated by spectrometric methods including ESI-HR, EI, D/CI mass spectrometry, H-1, C-13, and 2D NMR experiments, and chemical derivatization. Neither heliotropamide nor its acetylated derivative (1a) showed any antifungal activity against Cladosporium cucumerinum and Candida albicans, antibacterial activity against Bacillus subtilis, radical-scavenging properties in the DPPH test, or inhibitory potential toward acetylcholinesterase.
