ChEBI: 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 lpha,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-anthra ilate 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 NH1O linkage.

Esperamicin A1, as an extremely potent antitumor antibiotic, is isolated from cultures of Actinomadura verrucosospora. Esperamicin A1 can be used for the research of antitumor[1]. Eesperamicin A1 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
