C20H35NO13 (497.21083000000004)
A member of the class of validamycins that is (1R,2S,3S,4S,6R)-4-amino-6-(hydroxymethyl)cyclohexane-1,2,3-triol in which the hydroxy group at position 1 has been converted to its beta-D-glucoside and in which one of the hydrogens attached to the nitrogen is replaced by a (1R,4R,5R,6S)-4,5,6-trihydroxy-3-(hydroxymethyl)cyclohex-2-en-1-yl group. It is the major validamycin produced by Streptomyces hygroscopicus. Validamycin A, a fungicidal, is an agricultural antibiotic. Validamycin A is originally isolated from Streptomyces hygroscopicus var. limoneus. Validamycin A inhibits the growth of A. flavus, with a MIC of 1?μg/mL[1]. Validamycin A shows potent inhibitory activity against trehalase of Rhizoctonia solani, with an IC50 of 72 μM[2]. Validamycin A is a reversible tyrosinase inhibitor, with a Ki of 5.893 mM[3].
