A process for the preparation of solid amine salts of aromatic substituted carboxylic acid herbicides by reaction of the aromatic substituted carboxylic acid herbicide with an amine comprising reacting the aromatic substituted carboxylic acid herbicide in an ether solvent with an amine to form the amine salt and collecting the amine salt of the aromatic substituted carboxylic acid herbicide as a precipitate from the ether solvent reaction mixture wherein the ether is a dialiphatic ether comprising at least one primary aliphatic group.

The present invention is a mitochondria-targeted antioxidant prodrug useful for the prevention or treatment of diseases or conditions associated with mitochondrial dysfunction resulting from changes in the mitochondrial redox environment. Antioxidant prodrugs of the invention are produced by modifying an antioxidant to a fatty acid so that the resulting prodrug is targeted to and activated by an enzyme of mitochondrial fatty acid beta-oxidation.
MDH1 and MDH2 enzymes play an important role in the survival of lung cancer. In this study, a novel series of dual MDH1/2 inhibitors for lung cancer was rationally designed and synthesized, and their SAR was carefully investigated. Among the tested compounds, compound 50 containing a piperidine ring displayed an improved growth inhibition of A549 and H460 lung cancer cell lines compared with LW1497

Enoyl acyl carrier protein reductase (ENR) is an essential type II fatty acid synthase (FAS-II) pathway enzyme that is an attractive target for designing novel antitubercular agents. Herein, we report sixty-eight novel pyrrolyl substituted aryloxy-1,3,4-thiadiazoles synthesized by three-step optimization processes. Three-dimensional quantitative structure-activity relationships (3D-QSAR) were established for pyrrolyl substituted aryloxy-1,3,4-thiadiazole series of InhA inhibitors using the comparative molecular field analysis (CoMFA). Docking analysis of the crystal structure of ENR performed by using Surflex-Dock in Sybyl-X 2.0 software indicates the occupation of pyrrolyl substituted aryloxy 1,3,4-thiadiazole into hydrophobic pocket of InhA enzyme. Based on docking and database alignment rules, two computational models were established to compare their statistical results. The analysis of 3D contour plots allowed us to investigate the effect of different substituent groups at different positions of the common scaffold. In vitro testing of ligands using biological assays substantiated the efficacy of ligands that were screened through in silico methods. (C) 2015 Elsevier Inc. All rights reserved.
