esperamicin a1
esperamicin A1: from Actinomadura verrucosospora; RN refers to (1S,(1R*,4Z,8S*,12S*,13E))-isomer. esperamicin A1 : A naturally occurring antibiotic and antitumor agent isolated from Actinomadura verrucosopora. Its chemical structure consists of a core bicyclo[7.3.1]tridecadiynene moiety containing a 1,5-diyn-3-ene as part of a ten-membered ring, a alpha,beta-unsaturated ketone with a bridgehead double bond and an attached allylic trisulfide. This ring system is attached at one end by a trisaccharide moiety and at the opposite end by a 2-deoxy-L-fucose-anthranilate moiety. The trisaccharide consists of a hydroxyamino sugar which is connected to a isopropylamino sugar through a glycosidic linkage and a thiomethyl sugar through an NH-O linkage. | 2 | 1 | 0 | | |
