Abstract
Two new limonoids, chukrasone A (1) incorporating a highly rearranged A/B ring system and chukrasone B (2) possessing the first 16,19-dinor limonoid backbone with an extended C3 unit at C-15, were isolated from Chukrasia tabularis. Their structures were characterized on the basis of detailed spectroscopic analysis. Compounds 1 and 2 exhibited potential inhibition of the delayed rectifier (I(K)) K(+) current.
