The heteronemin, a marine sesterterpene isolated from the sponge Hyrtios sp., inhibits NF-[kappa]B activation and activates both initiator caspase-8 and caspase-9, which are implicated in the extrinsic and intrinsic apoptotic pathway, respectively, in chronic myelogenous leukemia cells [82].
Examples include salinamides A and B, which are depsipeptides produced by a marine streptomycete [23]; the cyclomarins, which are cyclic peptides that are also produced by a marine streptomycete [24]; lobophorins A and B, which are complex macrolides isolated from marine actinomycete cultures [25]; mangicols A and B, which are sesterterpenes isolated from the marine fungus Fusarium heterosporum [26]; and mycoepoxidiene, which is produced by a fungus in the genus Diaporthe [27].
