Latest Patents

Kirchhoff holds a patent titled "Methods and systems for estimating binding affinity." This patent outlines methods and systems for predicting the binding affinity between a ligand and a receptor. In one embodiment, the predicted binding affinity (pKj) is determined using a formula that incorporates various interaction energies. The formula is expressed as pKj = C0 + C1*vdW + C2*Att_pol + C3*(Att_pol*Att_pol + Rep_pol*Rep_pol). Here, vdW represents the van der Waals interaction energy, Att_pol denotes the surface area of the ligand forming complimentary polar interactions, and Rep_pol indicates the surface area of the ligand forming uncomplimentary polar interactions. Additionally, the patent describes an improved process for calculating linear interpolation of grid-based vdW energy, which enhances accuracy in estimating binding affinities.
