![]() ![]() ![]() W.r.t ratio of actives to decoys, there are no specific rules as such but most studies usually use about 1000 decoys and ~100-300 actives if available. Validation with known actives is absolutely necessary for a pharmacophore hypothesis, to see if it can distinguish the actives from random molecules or not. Are the other 4-5 known actives which you plan to use for validation different from these two? Ideally you should have more known actives for validation, but since you don't I suggest at least go ahead with the molecules you have for validation. Characterization of the binding behavior plays an important role in the rational design of drugs and elucidating fundamental biochemical processes.Īs I understand it, you've derived the pharmacophore from two known actives co-crystallised with your protein structure. Molecular docking is one of the most frequently used methods in structure-based drug design due to its ability to predict the binding conformation of small-molecule ligands to the appropriate target binding site. Therefore, docking is useful for predicting both the strength and type of signal produced. ![]() Furthermore, the relative orientation of the two interacting partners may affect the type of signal produced (e.g., agonism vs. The associations between biologically relevant molecules such as proteins, peptides, nucleic acids, carbohydrates, and lipids play a central role in signal transduction. Knowledge of the preferred orientation, in turn, may be used to predict the strength of association or binding affinity between two molecules using, for example, scoring functions. ![]() Introduction: In the field of molecular modeling, docking is a method that predicts the preferred orientation of one molecule to a second when bound to each other to form a stable complex. ![]()
