ABSTRACT
New 36-membered polyol macrolides deplelides A and B were isolated from the culture of Streptomyces MM581-NF15 by bioassay-guided fractionation using an ATP depletion assay. The planar structures of these novel compounds were identified by interpretation of the spectroscopic data (1D/2D NMR, MS, and IR). The relative stereochemistry was partially established using the universal NMR database method and J-based configuration analysis using 1H-1H and long-range 1H-13C coupling constants determined by 1H NMR or E.COSY and J-resolved HMBC analysis or another HMBC-based technique, respectively. The absolute stereochemistry was partially determined by a modified Mosher's method. These new compounds displayed highly potent ATP depletion activities (IC50 33 nM) and antiproliferative activities against several tumor cell lines, such as HGC-27 (IC50 47 nM).
