Michael;Witt, Ken A. research published 《 Synthesis and structure-activity relationships of 3,4,5-trisubstituted-1,2,4-triazoles: high affinity and selective somatostatin receptor-4 agonists for Alzheimer′s disease treatment》, the research content is summarized as follows. Somatostatin receptor-4 (SST₄) is highly expressed in brain regions affiliated with learning and memory. SST₄ agonist treatment may act to mitigate Alzheimer′s disease (AD) pathol. An integrated approach to SST₄ agonist lead optimization is presented herein. High affinity and selective agonists with biol. efficacy were identified through iterative cycles of a structure-based design strategy encompassing computational methods, chem., and preclin. pharmacol. 1,2,4-Triazole derivatives of our previously reported hit (4) showed enhanced SST₄ binding affinity, activity, and selectivity. Thirty-five compounds showed low nanomolar range SST₄ binding affinity, 12 having a K_i < 1 nM. These compounds showed >500-fold affinity for SST₄ as compared to SST_2A. SST₄ activities were consistent with the resp. SST₄ binding affinities (EC₅₀ < 10 nM for 34 compounds). Compound 208 (SST₄K_i = 0.7 nM; EC₅₀ = 2.5 nM; >600-fold selectivity over SST_2A) display a favorable physiochem. profile, and was advanced to learning and memory behavior evaluations in the senescence accelerated mouse-prone 8 model of AD-related cognitive decline. Chronic administration enhanced learning with i.p. dosing (1 mg kg^-1) compared to vehicle. Chronic administration enhanced memory with both i.p. (0.01, 0.1, 1 mg kg^-1) and oral (0.01, 10 mg kg^-1) dosing compared to vehicle. This study identified a novel series of SST₄ agonists with high affinity, selectivity, and biol. activity that may be useful in the treatment of AD.

A new method for the synthesis of substituted quinazolines by the condensation of 2-nitrobenzyl alcs. with arylacetic acids.

Nope, Eliana;Sathicq, Angel G.;Martinez, Jose J.;Rojas, Hugo;Romanelli, Gustavo research published 《 Hydrotalcites as catalyst in suitable multicomponent synthesis of uracil derivatives》, the research content is summarized as follows. In this work, the multicomponent synthesis of uracil derivatives assisted by layered double hydroxides (LDH) was studied under green chem. conditions. The incorporation of Ni²⁺ or Co²⁺ was successfully performed by co-precipitation method. The yields to uracil derivatives were associated with the presence of weak basic sites and a better interaction of the reagents when the reaction was carried out in solvent-free conditions. The reaction pathway involved the formation of an enone between benzaldehyde and Et cyanoacetate, and subsequent reaction with urea, which was assisted by the presence of a basic catalyst. The scope of this synthesis was illustrated with nine examples.

L.;Maxwell, Anthony;McPhillie, Martin J.;Fishwick, Colin W. G. research published 《 De novo design of type II topoisomerase inhibitors as potential antimicrobial agents targeting a novel binding region》, the research content is summarized as follows. By 2050, it is predicted that antimicrobial resistance will be responsible for 10 million global deaths annually, more deaths than cancer, costing the world economy $100 trillion. Clearly, strategies to address this problem are essential as bacterial evolution is rendering our current antibiotics ineffective. The discovery of an allosteric binding site on the established antibacterial target DNA gyrase offers a new medicinal chem. strategy. As this site is distinct from the fluoroquinolone binding site, resistance is not yet documented. Using in silico mol. design methods, we have designed and synthesized a novel series of biphenyl-based inhibitors inspired by a published thiophene-based allosteric inhibitor. This series was evaluated in vitro against Escherichia coli DNA gyrase and E. coli topoisomerase IV with the most potent compounds exhibiting IC₅₀ values towards the low micromolar range for DNA gyrase and only ∼2-fold less active against topoisomerase IV. The structure-activity relationships reported herein suggest insights to further exploit this allosteric site, offering a pathway to overcome developing fluoroquinolone resistance.
