A Streptomyces Sp. NLKB45 was isolated from the Nellore coastal region. After checking antimicrobial and antifungal activity the strain was subjected to fermentation in starch casein broth medium. HPLC was used to purify the culture filtrate after it had been extracted with ethyl acetate. The extract showed antibacterial and anticancer properties. The extract was processed and the compound isolated was further analyzed using FTIR, mass spectroscopic method and one- and two-dimensional NMR techniques. Based on the data gathered the compound was identified as 7-((5-methylpyridin-2-ylamino) (phenyl) methyl) quinolin-8-ol with a weight-average molecular weight of about 341 Da.
