Fistulains A and B (1 and 2), two novel bischromones with unique coupling patterns, alone with their biosynthetic related compound 3, were isolated from the bark of Cassia fistula. Fistulain A represents a new type of dimeric chromone alkaloid biogenetically derived from a chromone and a tricyclic alkaloid through an unusual C-14-N linkage. Fistulain B has a new carbon skeleton with a C-14-C-5' linkage formed between two different chromone units. Fistulain A displayed anti-TMV activity, and… CONTINUE READING
