| An inhibitor of trehalase. Validamycin A is an antifungal agent used to protect rice plants against sheath blight caused by the pathogenic fungus, R. solani, due to its ability to inhibit trehalase, a trehalose-hydrolizing enzyme (Ki = 1.9nM, IC50 = 0.7uM).1 It is also effective against the growth and sporulation of R. cerealis, F. culmorum, and other fungi.2 This compound has also been used to study trehalase activity and trehalose biosynthesis.3 Synonyms: 1,5,6-Trideoxy-4-O-beta-D-glucopyranosyl-5-(hydroxymethyl)-1-[[(1S,4R,5S,6S)-4,5,6-trihydroxy-3-(hydroxymethyl)-2-cyclohexen-1-yl]amino]-D-chiro-inositol, Cepex 10SL, Jinganmycin A, Jinggang, Jinggangmycin, Jinggangmycin A, Validacin, Validamycin, Validamycin A, [1S-(1alpha,4alpha,5beta,6alpha)]-1,5,6-Trideoxy-4-O-beta-D-glucopyranosyl-5-(hydroxymethyl)-1-[[4,5,6-trihydroxy-3-(hydroxymethyl)-2-cyclohexen-1-yl]amino]-D-chiro-inositol CAS No: 37248-47-8 Molecular Formula: C20H35NO13 Molecular Weight: 497.49 Appearance: Off-white to yellow powder Purity: 64% pH: 2.5-5.0 Water: 5% Water Insoluble: 0.2% Solubility: DMSO, Methanol (Slightly), Water (Slightly) Storage: -20C.
