Abstract

Actinobacteria isolated from marine sources are a potential source of novel natural products. In this study, we report isolation, biological activity and characterization of secondary metabolites from strain Nocardiopsis sp. SCA30, isolated from marine sediments of Havelock Islands, Andaman and Nicobar, India. The ethyl acetate extracts of the isolate on screening for biological activity demonstrated antibacterial potency and antiproliferative activity. The extracts showed anticancer activity in a panel of cell lines, including HCT 15, HT 29, MCF 7 and MDA-MB 468, at concentrations ranging from 62.5 to 1000 µg/ml. A dose-dependent reduction in cell viability was observed in all the tested cell lines. The extract at 15 µg/ml and 30 µg/ml inhibited growth of methicillin-resistant Staphylococcus aureus ATCC NR-46071 and NR-46171 with MIC’s of 15.62 and 7.81 µg/ml, respectively. LC–MS and NMR studies revealed that the antibacterial and anticancer compound isolated from Nocardiopsis sp. SCA30 is 1-acetyl-4-4(hydroxyphenyl)piperazine.
