Abstract: In this study, a 2D-QSAR (quantitative structure–activity relationship) was performed on 54 new 2-Styrylquinoline derivatives as anticancer substances capable of inhibiting the p53 protein in the cell HCT116++. The 54 2-Styrylquinoline derivatives was calculated applying DFT 6- 31G basis to calculate Quantum descriptors, using MM2 for: Topological, Physico-chemical, Geometrical and Constitutional. The study was carried out by performing multiple linear regression (R2 = 0.90), the QSAR model achieved was tested by artificial neural networks method, which is showed high predictability (R2 ANN = 0.89). A DFT study was performed to determine the reactivity of the 2-Styrylquinoline derivatives using frontier molecular orbital analysis and analysis of the molecular electrostatic potential (MEP). Derivatives of 2–4 Styrylquinoline are studied for their synthetic accessibility and their similarity to drug. The obtained results show that all the evaluated compounds have similar properties to drug and are accessible to synthesize. A molecular docking analysis was performed for three compounds: 14, 34, and 54, having various reactivities against the p53 HCT116++ protein (identified by PDB ID: 2GEQ). The results showed strong interactions between the three ligands and the 2GEQ protein, the amino acids HIS 176, SER A180, PRO A188 and ARG A178 are the most active sites of the 2GEQ protein, and based on these result we performed a molecular dynamics simulation to evaluate the stability of our complexes. The MD demonstrates the thermodynamic stability of select compounds during 40 and 100 ns, with all three complexes showing a high level of structural stability
