ItemBioactive metabolites produced by pseudonocardia endophytica VUK-10 from mangrove sediments: Isolation, chemical structure determination and bioactivity( 2015-01-01) Mangamuri, Usha Kiranmayi ; Vijayalakshmi, Muvva ; Poda, Sudhakar ; Manavathi, Bramanandam ; Bhujangarao, C. H. ; Venkateswarlu, Y.Chemical investigation of the actinobacterial isolate Pseudonocardia endophytica VUK-10 has led to the segregation of two known bioactive compounds, namely 4-(2-acetamidoethyl) phenyl acetate and 4-((1, 4-dioxooctahydropyrrolo [1, 2-a] pyrazin-3-yl) methyl) phenyl acetate. The strain was isolated from a sediment sample of the Nizampatnam mangrove ecosystem, south coastal Andhra Pradesh, India. The chemical structure of the active compounds was established on the basis of spectroscopic analysis, including < sup > 1 < /sup > H NMR and < sup > 13 < /sup > C NMR spectroscopies, FTIR, and EIMS. The antimicrobial and cytotoxic activities of the bioactive compounds produced by the strain were tested against opportunistic and pathogenic bacteria and fungi and on MDA-MB-231, OAW, HeLa, and MCF-7 cell lines. The compounds exhibited antimicrobial activities against gram-positive and gram-negative bacteria and fungi and also showed potent cytotoxic activity against MDA-MB-231, OAW, HeLa, and MCF-7 cell lines. This is the first example for this class of bioactive compounds isolated from Pseudonocardia of mangrove origin.
