longirostrerone C
An azaphilone that is 9,9a-dihydro-6H-furo[2,3-h]isochromene-6,8(6aH)-dione substituted by a 6-methyl-2-oxocyclohex-3-en-1-yl group at position 3, a methyl group at position 6a and a 4,6,8-trimethyldeca-2,4-dienoyl group at position 9. Isolated from Chaetomium longirostre, it exhibits cytotoxic and antimalarial activities.
