ABSTRACT
Novel anticancer drugs of natural origin have increased tremendously due to the resistance of multiple chemotherapeutic drugs in breast cancer therapy and their high toxicity with undesirable side effects. The study investigates the bioactivity of secondary metabolites derived from Bacillus cereus PSMS6 isolated from marine soil sediment in the Velar estuary, Parangepattai, Cuddalore district, Tamil Nadu, and India. Strains were isolated and antagonistic activity was screened using the agar well diffusion method. B. cereus PSMS6 exhibited potency, and its crude extract was tested for antioxidant, anticancer, and cytotoxic MTT assay potential. The methanolic extract of B. cereus PSMS6 was analyzed by mass spectrometry HRLC-MS and FT-IR to determine the bioactive compounds. A drug interaction study with the anti-breast cancer protein HER2 was performed by molecular docking analysis. Antioxidant activities were determined using total antioxidant scavenging assay, ABTS and DPPH free radical scavenging assays. The total antioxidant scavenging assay of the crude extract of B. cereus methanol had an IC50 value of 28.33±1.01, in ABTS IC50 value of the extract was 29.00±0.28 and in DPPH the IC50 of the extract was 34.91±0.09. The negative ion compound Palmitoylglycerone phosphate had a LibDock score of 149.487 and the positive ion compound N5-(4-Methoxybenzyl) glutamine had 120.116. These compounds show promising anticancer activity. The current study reported that the bioactive secondary metabolite of B. cereus PSMS6 retains anti-cancer, and antioxidant properties. This is the first report to show the production of the Palmitoylglycerone phosphate metabolite from B. cereus PSMS6.
