ABSTRACT
AIM:
This study aimed to use one strain many compounds approach (OSMAC) to investigate the cytotoxic potential of Aspergillus terreus associated with soybean versus several cancer cell lines, by means of in-silico and in vitro approaches. METHODS ANDRESULTS:
Fermentation of the isolated strain was done on five media. The derived extracts were investigated for their inhibitory activities against three human cancer cell lines; mammary gland breast cancer (MCF-7), colorectal adenocarcinoma (Caco-2), and hepatocellular carcinoma (HepG2) using MTT Assay. The fungal mycelia fermented in Modified Potato Dextrose Broth (MPDB) was the most cytotoxic extract against HepG2, MCF-7, and Caco-2 cell lines with IC50 4.2 ± 0.13, 5.9 ± 0.013 and 7.3 ± 0.004 µg mL-1, respectively. MPDB extract was scaled up resulting in the isolation of six metabolites; three fatty acids (1, 2, and 4), one sterol (3) and two butenolides (5 and 6) by column chromatography. The isolated compounds (1-6) were screened through a molecular docking approach for their binding aptitude to various active sites. butyrolactone-I (5) revealed a significant interaction within the CDK2 active site, while aspulvinone E (6) showed promising binding affinity to FLT3 and EGFR active sites that was confirmed by in vitro CDK2, FLT3 and EGFR inhibitory activity. Finally, the in vitro cytotoxic activities of butyrolactone-I (5) and aspulvinone E (6) revealed the antiproliferative activity of butyrolactone-I (5), against HepG2 cell line (IC50 = 17.85 ± 0.32 µM).CONCLUSION:
Molecular docking analysis and in vitro assays suggested the CDK2/A2 inhibitory potential of butyrolactone-I (5) in addition to the promising interaction abilities of aspulvinone E (6) with EGFR and FLT3 active sites as a possible mechanism of their biological activities.Palabras clave
