The molecule is a polyene antibiotic that is 2-amino-4,5-dihydroxycyclohex-2-en-1-one in which the hydrogen at position 4 is replaced by a by an all-E-6-carboxyhexa-1,3,5-trien-1-yl group; in which the amino group has been acylated by a (2E)-2,4-dimethyloct-2-enoyl group; and in which the carboxy group of the resulting carboxylic acid has been condensed with the amino group of 2-amino-3-hydroxycyclopent-2-en-1-one to give the corresponding carboxamide. TMC-1A is an antitumour antibiotic isolated from Streptomyces sp. A-230. It has a role as an antineoplastic agent and a bacterial metabolite. It is a secondary alcohol, a tertiary alcohol, an enol, a cyclic ketone, a polyene antibiotic, an enone, an enamide and a secondary carboxamide.
