Synthesis and methemoglobinemia-inducing properties of benzocaine isosteres designed as humane rodenticides
摘要:
A number of isosteres (oxadiazoles, thiadiazoles, tetrazoles and diazines) of benzocaine were prepared and evaluated for their capacity to induce methemoglobinemia-with a view to their possible application as humane pest control agents. It was found that an optimal lipophilicity for the formation of methemoglobin (metHb) in vitro existed within each series, with 1,2,4-oxadiazole 3 (metHb% = 61.0 +/- 3.6) and 1,3,4-oxadiazole 10 (metHb% = 52.4 +/- 0.9) demonstrating the greatest activity. Of the 5 candidates (compounds 3, 10, 11, 13 and 23) evaluated in vivo, failure to induce a lethal end-point at doses of 120 mg/kg was observed in all cases. Inadequate metabolic stability, particularly towards hepatic enzymes such as the CYPs, was postulated as one reason for their failure. (C) 2014 Elsevier Ltd. All rights reserved.
(NAPE-PLD) is a membrane-associated zinc enzyme that catalyzes the hydrolysis of N-acylphosphatidylethanolamines (NAPEs) into fatty acid ethanolamides (FAEs). Here, we describe the identification of the first small-molecule NAPE-PLD inhibitor, the quinazoline sulfonamide derivative 2,4-dioxo-N-[4-(4-pyridyl)phenyl]-1H-quinazoline-6-sulfonamide, ARN19874.

The present invention is further directed to pharmaceutical compositions comprising the compounds of the present invention and to methods for treating conditions such as cancers and other cell proliferative disorders.
and 40 have pivotal anticancer activity. Among these, compounds 22 and 27 have significant cytotoxic activity in all three cell lines; the in silico docking studies also reveal that compounds 22, 27 and 36 have good dock scores, binding affinities and binding energies towards human epidermal growth factor receptor 2. This is the first report to demonstrate theophylline hybrids containing 1,2,3-triazoles
recent developments, this work demonstrates the utilization of a chelating template backbone bearing covalently attacheddirecting groups, which enables site‐selective remote C−H functionalization of heterocycles. The observed selectivity is the outcome of non‐covalent interactions between the heterocycles and bifunctional template backbone.
