PhiKan 083 is a critical p53 stabilizing agent by bonding its mutation Y220C
The mutation Y220C of p53 exists a surface cavity that destabilizes the protein by 4 kcal/mol, at a site that is not functional. A p53 stabilizing agent binding it is able to slow rate of thermal denaturation .
In vitro: Isothermal titration of PhiKan083 with T-p53C-Y220C exhibited 1:1 stoichiometry and a Kd of 125 ± 10 M. PhiKan083 stabilized T-p53C-Y220C in a concentration-dependent manner. In a simple binding model for PhiKan083 (T-p53C-Y220C at 310 K (37°C)), in the absence of ligand, the protein gave a half-life of 3.8 min, while it increased to 15.7 min at saturating concentrations of PhiKan083. This is a proposed anticancer drug that could be developed for the Y220C mutant using p53 stabilizing agent. The site of mutation in the oncogenic Y220C mutant PhiKan083 binds with reasonable affinity is a druggable target. Interestingly, the site of mutation does not exist in a region of the protein that is functionally important, it will be an excellent target for drug stabilization therapy. This suggests the crystal structure of the complex will be a fresh start for further rounds of drug design and refinement .
