Alchem. free energy methods have gained much importance recently from several reports of improved ligand-protein binding affinity predictions based on their implementation using mol. dynamics simulations. A large number of variants of such methods implementing different accelerated sampling techniques and free energy estimators are available, each claimed to be better than the others in its own way. However, the key features of reproducibility and quantification of associated uncertainties in such methods have barely been discussed. Here, we apply a systematic protocol for uncertainty quantification to a number of popular alchem. free energy methods, covering both absolute and relative free energy predictions. We show that a reliable measure of error estimation is provided by ensemble simulation-an ensemble of independent MD simulations-which applies irresp. of the free energy method. The need to use ensemble methods is fundamental and holds regardless of the duration of time of the mol. dynamics simulations performed. This study involved multiple reactions and reactants, such as 1-(tert-Butyl)-3-(2-((4-(diethylamino)butyl)amino)-6-(3,5-dimethoxyphenyl)pyrido[2,3-d]pyrimidin-7-yl)urea (cas: 219580-11-7Recommanded Product: 219580-11-7).
1-(tert-Butyl)-3-(2-((4-(diethylamino)butyl)amino)-6-(3,5-dimethoxyphenyl)pyrido[2,3-d]pyrimidin-7-yl)urea (cas: 219580-11-7) belongs to pyrimidine derivatives. The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.Recommanded Product: 219580-11-7
