Background: The main aim of the study was to evaluate the bioactive properties of ethyl acetate crude extract of Streptomyces sp. VITASP with a view to assess their therapeutic potential.Methods: The morphological, physiological and the biochemical properties of the strain Streptomyces sp. VITASP were confirmed by conventional methods. The present study evaluated the antibacterial, antioxidant and cytotoxic activities. Results: The isolate was identified to be Streptomyces sp. (Genbank accession number: KR233807). The ethyl acetate extract of Streptomyces sp. VITASP showed maximum antibacterial activity of two Gram- positive and Gram- negative bacteria at 0.5mg/mL. The antioxidant potential of the crude extract exhibited strong reducing power activity at 0.5 mg/mL with 93±0.05% inhibition. The antiinflammatory and anti-diabetic properties were identified at 0.5 mg/mL concentration. The cytotoxic effect was found with an IC50 of 500
