Özet: In our screening for antitubercular leading compounds, an endophytic Streptomyces sp. YIM65484 was selected by biological assay. Four bioactive metabolites were isolated from this strain. Their structures were determined as (2E,4E)-5-(3-hydroxyphenyl)- penta-2,4- dienamide (1), ergosterol (2), ergosterol peroxide (3) and halolitoralin B (4) by spectral analysis. Compound 1 is a new phenylpentadienamide with its rarely encountered skeleton in natural products. Compounds 1-4 showed selectivity for anti-M. Tuberculosis activity in comparison with other antimicrobial activity. Compound 4 was first isolated from Streptomyces.
