Recent advances demonstrate phytochemicals to be a potent anticancer therapeutic agent as various anti-cancer targets. This study depicts the anti-cancer potential against certain crucial common cancer targets leading to cancer cell proliferation and survival. The main objective of this study is to study the anti-cancer potential of phloretin against certain cancer targets. Ligand analysis was performed and Phloretin was chosen as the experimental ligand and Bcl-2, NF Kappa B, Carbonic anhydrase I (CA-1), Inducible Nitric Oxide Synthase (iNOS), Endothelial Nitric oxide synthase (eNOS), Caspase 3, and Caspase 9 proteins were chosen as targets. Induced fit molecular docking was performed by the use of Glide 6.5 software (Schrodinger - 2015). The docked poses were further evaluated based on binding energy, Conformational changes, and the amino acid residues involved in the protein-ligand interaction. The docking results depicted that phloretin showed notable binding affinity especially with carbonic anhydrase I, ENOS, and INOS. It also showcased significant potential against Caspase 3 and NF Kappa, thereby showing its potential as an effective anti-cancer therapeutics. During this study, the Inhibitory potential of Phloretin was studied as a result of this molecular docking study. This Insilico study revealed the binding efficiency of phloretin against the aforementioned targets. In vitro analysis is required for further validation of this data.

<p><strong>Objective</strong>:<strong> </strong>The present work aimed to synthesize a new series of 1-methylsulphonyl-3-indolyl heterocycles and study their cytotoxic activity. In addition, we attempted to explore the mode of the interaction of anti-proliferative compounds with the active site of carbonic anhydrase IX (CA IX) theoretically <em>via</em> molecular docking study.</p><p><strong>Methods</strong>:<strong> </strong>Novel series of pyrazole, pyrimidine and triazole derivatives bearing 1-methylsulphonyl-1<em>H</em>-indole were prepared <em>via</em> a series of hetero cyclization reactions utilizing 3-(1-methylsulphonyl-1<em>H</em>-indol-3-yl)-1-(substituted phenyl)-1<em>H</em>-pyrazole-4-carboxaldehydes 3a-d and 3-chloro-3-(1-methylsulphonyl-1<em>H</em>-indol-3-yl)propenal (6) and evaluating their anti-proliferative activity. The structures of the newly synthesized compounds were confirmed by elemental analyses, IR, NMR and mass spectral data. In addition, molecular docking study of the most promising antiproliferative compounds against the active site of carbonic anhydrase IX (PDB ID: 4BCW) theoretically is discussed.</p><p><strong>Results</strong>:<strong> </strong>Compounds 5c, 7 and 12 revealed potent anti-proliferative effects against A-549 cancer cell line with IC<sub>50</sub> of 44.3, 17.2 and 38.7 µmol/l, respectively compared to the reference drug doxorubicin (IC<sub>50</sub> of 48.8 µmol/l). While compound <strong>5c</strong> was found to be highly active with IC<sub>50</sub> of 5.66 µmol/l against HCT-116 cancer cell line than doxorubicin (IC<sub>50</sub> of 65.00 µmol/l).</p><p><strong>Conclusion</strong>:<strong> </strong>Further work is recommended to confirm the inhibition of CA IX in a specific bioassay.</p>
