In Silico Studies of Two Biphenyl Based Oxime Containing Ligands

Two biphenyl based ligands were tested for their molecular docking, ADME and toxicity properties in silico. Molecular docking studies performed with two factors (VEGFR-2 and EGFRK) which are known to be effective in tumor growth. Two ligands were similar in structure except one atom difference between ligands which is H and Cl. This small difference made an important impact on the molecular docking energy scores of ligand protein couples. The Cl atom containing ligand-protein complexes showed drastically elevated energy levels which might be due to higher electronegativity of Cl atom. ADME properties of two ligands were also alike except a few parameters as the inhibition of two conjugation enzymes (CYP2C19 ve CYP2C9). The biggest difference shown by the ligands were the elimination of carcinogenicity and mutagenicity of H containing ligand by Cl atom containing ligand. Druglikeness of two biphenyl based oxime containing ligands was also tested and the results of a single atom exchange were evaluated in terms of new drug design and discovery.
