Abstract
Two 3β-methoxy secosteroids, named jereisterol A (I) and B (II) were isolated from the pacific sponge J. graphidiophora. Their structures, which combine rare 3β-methoxy and seco features, were detd. as (24R) 24-methyl-3β-methoxy-8α,9α-oxido-8,9-secocholesta-7,9(11)-diene and (24R) 24-methyl-3β-methoxy-8,14-secocholesta-8,14-dione, resp.File in questo prodotto:
