In silico bimolecular characterization of anticancer phytochemicals from Fagonia indica.

The in silico molecular dynamics and structure-based site-specific drug design of indigenous plant biomolecules and selected proteins have remarkable potential for cancer therapy. A set of five proteins included for this research were epidermal growth factor protein (PDB ID; 1M17), crystal structure of mutated EGFR kinase (PDB ID; 2EB3), crystal structure of Bcl-xl (PDB ID; 2YXJ), apoptosis regulator protein MCL-1 BH3 (PDB ID; 3MK8) and apoptosis proteins (PDB ID; 5C3H). The present study on in silico investigation of fifteen indigenous medicinal plants were selected there one hundred thirty four ligands available literature were docked against five proteins involved in carcinogenesis. The highest scoring in silico plant, Fagonia indica was subjected to in vitro cytotoxic effects on HCT116, HepG-2 and HeLa human carcinoma cell lines. Molecular dynamics showed best ligand-protein inhibition interaction between Coumarin-2xyj and Kaempferol-2eb3 with promising binding affinities. Whereas, on HeLa human cervical cancer cell line IC50 was 28.3±0.102/ml. Fagonia indica could be potential source from natural products that have cytotoxic properties against cervical cancer cells by blocking mutant epidermal growth factor tyrosine or peroxisome proliferators activated receptor proteins.

In vitro antimutagenic, cytotoxic and anticancer potential of Fagonia indica phytochemicals.

Cancer is one of the most diagnosed and life threatening disease throughout the world. Nevertheless present day clinical management for cancers are surgery, radiations which are insufficient to contain the disease burden. In the past two decades, more than half of chemotherapeutic drugs developed are either directly or indirectly dependent on medicinal base phytocompounds or their derivative. The present study aims to provide the base for chemotherapeutic phytochemicals. Fagonia indica showed significant antimutagenic potential with reference to control IC50 values were calculated as 146.33±5.2µg/ml, TA100 (AZS) 105.33±4.0µg/ml, TA98 (2AA) 113.6±5.2µg/ml followed and TA98 (AZS) 112.6±4.4 in Ames test. For this reason, the antiproliferation effect of extracts on cancer cell lines was studied through resazurin fluorescence. On HepG-2 cell lines 50% cytotoxic concentration (CC50) of (FIWM) was recorded as 128.3±,2.43µg/ml. On the homo sapiens epithelial cell of lung tissue (A549), the high throughput instrumental analysis of Fagonia indica depicts maximum cytotoxic effect in 30hr. The electrical impedance displays the real-time evidence about qualitative apoptosis expressed. The impedance results were supported as palmitic acid from Fagonia indica virtually that inhibits Cyclin Dependent Kinase 2 (CDKs 2) in silico molecular docking studies. Fagonia indica extract possesses substantial antimutagenic, cytotoxic and anticancer activity which supports the potential of its phytochemicals for drug development.
