1. FR65814, a novel immunosuppressant isolated from a Penicillium strain. Taxonomy, fermentation, isolation, physico-chemical and biological characteristics and structure assignment
H Hatanaka, T Kino, M Hashimoto, Y Tsurumi, A Kuroda, H Tanaka, T Goto, M Okuhara J Antibiot (Tokyo). 1988 Aug;41(8):999-1008. doi: 10.7164/antibiotics.41.999.
FR65814, a novel immunosuppressant, was isolated from the cultured broth of Penicillium jensenii F-2883. The structure was assigned to be 5,6-dihydroxy-4-(1,2-epoxy-1,5-dimethyl-4-hexenyl)-1-oxaspiro++ +[2,5]octane by spectroscopic analyses. The compound suppressed the immune response at low concentration. In addition, a structually related component fumagillol, a known carcinolytic agent, was also isolated and found to show immunosuppressive activity.
