Quantitative Structure–Activity Relationship Modeling of Kinase Selectivity Profiles

Bisphosphonate inhibition of phosphoglycerate kinase: quantitative structure-activity relationship and pharmacophore modeling investigation.

We report the results of a three-dimensional quantitative structure-activity relationship (3D-QSAR) and pharmacophore modeling investigation of the interaction of the enzyme 3-phosphoglycerate kinase (PGK) with aryl and alkyl bisphosphonates. For the human enzyme, the IC50 values are predicted within a factor of 2 over the 240x experimental range in activity, while for the yeast enzyme, binding...

Quantitative Structure-Pproperty Relationship Modeling of the Redox Potential for Some Phenolic Antioxidants

In this work, quantitative structure-property relationship (QSPR) approaches were used to predict the redox potential of 42 phenolic antioxidants. The structures of all compounds optimized by the AM1 semi-empirical method and then a large number of molecular descriptors were calculated for each compound in the data set. Subsequently, stepwise multilinear regression was applied to select the mos...

Structural insight into selectivity and resistance profiles of ROS1 tyrosine kinase inhibitors.

Oncogenic ROS1 fusion proteins are molecular drivers in multiple malignancies, including a subset of non-small cell lung cancer (NSCLC). The phylogenetic proximity of the ROS1 and anaplastic lymphoma kinase (ALK) catalytic domains led to the clinical repurposing of the Food and Drug Administration (FDA)-approved ALK inhibitor crizotinib as a ROS1 inhibitor. Despite the antitumor activity of cri...

Quantitative structure-selectivity relationship for M2 selectivity between M1 and M2 of piperidinyl piperidine derivatives as muscarinic antagonists.

Muscarinic M2 receptor antagonists with high subtype selectivity (M2/M1) will decrease the toxicity in central nervous system in treatment of AD. The exploration of quantitative structure-selectivity relationship (QSSR) to muscarinic M2 receptor antagonists will provide design information for drug with fewer side effects. In this paper, CoMFA models of pK(i)(M1), pK(i)(M2) and p[K(i)(M2)/K(i)(M...
