2,5-diamino-1,4-benzoquinones: Promising candidates against HT-29 human colorectal cancer cell line and as HSP90 inhibitors

Herein reporting the synthesis of seven 2,5-diamino-1,4-benzoquinones to act as potent anti-cancer agents against HT-29 human colorectal adenocarcinoma cell line via MTT assay, fluorescence microscopy and flow cytometric assays. All the aminobenzoquinones shows promising activity and 2,5-dibenzylamino-1,4-benzoquinone exhibits best results (IC50 12.5 μg/mL). Flouresence microscopic and cell cycle analysis were carried out to study the pathway of their activity. Molecular docking analysis using Schrodinger software were carried out to study the ability of these compounds to act as HSP90 inhibitors
