Alternatives to the use of pressurized hydrogen (H-2) in chemical syntheses are of growing interest and importance in developing safer protocols. Ammonia borane (AB), with its high hydrogen content and ability to release H-2 under mild conditions, is one potential solution. However, optimization of AB dehydrogenation and further the use of AB as a H-2 source to facilitate tandem one-pot reactions with both high activity and stability is an ongoing research challenge. In this work, monodisperse AuPd nanoparticle (NP) catalysts were synthesized and systematically studied for AB dehydrogenation, and Au-rich NPs were found to be the most active composition for AB methanolysis with a turnover frequency (TOF) of 160 min(-1) surpassing most Pd-based NP catalysts to date. More importantly, Au-rich NPs were also active in the one-pot tandem reduction of a series of nitro-groups and the hydrodehalogenation of mono- and polyhalogenated persistent chemical pollutants under mild reaction conditions using only a 2:1 molar ratio of AB to substrate. The AuPd catalyst was stable after ten reaction runs for AB methanolysis and five reaction runs for tandem one-pot reactions without a loss of activity or change in NP structure and morphology.

HPLC of Formula: C7H4Cl2O2. I found the field of Pharmacology & Pharmacy very interesting. Saw the article The Triazole Ring as a Privileged Scaffold for Putative Antifungals: Synthesis and Evaluation of a Series of New Analogues published in 2021, Reprint Addresses Zoidis, G (corresponding author), Natl & Kapodistrian Univ Athens, Dept Pharm, Athens 15771, Greece.. The CAS is 50-84-0. Through research, I have a further understanding and discovery of 2,4-Dichlorobenzoic acid.

The significant antifungal activity of a series of novel 1,2,4-triazole derivatives against different strains ofCandida albicans,Candida kruseiandAspergillus fumigatus, compared to the commercial fungicides ketoconazole and itraconazole, is reported. Systemic mycosis and invasive fungal infections, whether from immunodeficiency or hospital-acquired infection, have been on an upward trend for several years. The 1,2,4-triazole ring substituted with other aromatic and heteroaromatic systems plays an important role in the field of antifungal drug discovery and development. Thus, an extensive series of 29 triazoles, substituted in different positions with a variety of aromatic rings, has been designed, synthesized, and evaluated for their fungicidal activity. Almost all the agents testedin vitroshowed high activity against all examined fungal strains. It is noteworthy that, in the case ofA. fumigatus, all the examined compounds achieved equal or higher antifungal activity than ketoconazole, but less activity than itraconazole. Among all the derivatives studied, the dichlorourea analogue and bromo-substituted triazole stand out as the most promising compounds. Quantitative structure-activity relationship (QSAR) models were built for a systematic structure-activity relationship (SAR) profile to explain and potentially explore the potency characteristics of 1,2,4-triazole analogues.

Pyrazinamide is an important first-line drug used in shortening TB therapy. In our current work, a series of novel substituted-N-(6-(4-(pyrazine-2-carbonyl)piperazine/homopiperazine-1-yl)pyridin-3-yl)benzamide derivatives were designed, synthesized, and evaluated for their anti-tubercular activity against Mycobacterium tuberculosis H37Ra. Among the tested compounds, five compounds (6a, 6e, 6h, 6j and 6k) from Series-I and one compound (7e) from Series-II exhibited significant activity against Mycobacterium tuberculosis H37Ra with 50% inhibitory concentrations (IC50) ranging from 1.35 to 2.18 mu M. To evaluate the efficacy of these compounds, we examined their IC90 values. Five of the most active compounds were found to be more active with IC(90)s ranging from 3.73 to 4.00 mu M and one compound (6e) showed an IC90 of 40.32 mu M. Moreover, single crystals were developed for 6d, 6f and 6n. In addition, most active compounds were evaluated for their cytotoxicity on HEK-293 (human embryonic kidney) cells. Our results indicate that the compounds are nontoxic to human cells. The molecular interactions of the derivatised conjugates in docking studies reveal their suitability for further development.

A divergent approach has been successfully developed for the synthesis of N-1,2,4-oxadiazole substituted sulfoximines starting from N-cyano sulfoximines. This method has a wide degree of substrate scope that includes aryl, heteroaryl, alkyl, fluoroalkyl and saturated heterocyclic compounds. Excellent functional group tolerability was also observed. Extension of this methodology to nucleosides, amino acids and dipeptides was found to be successful. A gram scale reaction was also established. The major part of this method is metal free and the utility of environmentally friendly solvents such as 2-methyl THF and ionic liquids is an added advantage.

The A-type Aurora kinase is upregulated in many human cancers, and it stabilizes MYC-family oncoproteins, which have long been considered an undruggable target. Here, we describe the design and synthesis of a series of pyrimidine-based derivatives able to inhibit Aurora A kinase activity and reduce levels of cMYC and MYCN. Through structure-based drug design of a small molecule that induces the DFG-out conformation of Aurora A kinase, lead compound 13 was identified, which potently (IC50 < 200 nM) inhibited the proliferation of high-MYC expressing small-cell lung cancer (SCLC) cell lines. Pharmacokinetic optimization of 13 by prodrug strategies resulted in orally bioavailable 25, which demonstrated an 8-fold higher oral AUC (F = 62.3%). Pharmacodynamic studies of 25 showed it to effectively reduce cMYC protein levels, leading to >80% tumor regression of NCI-H446 SCLC xenograft tumors in mice. These results support the potential of 25 for the treatment of MYC-amplified cancers including SCLC.

Mycobacterium tuberculosis (M.tb), the etiologic agent of tuberculosis, remains the leading cause of death from a single infectious agent worldwide. The emergence of drug-resistant M.tb strains stresses the need for drugs acting on new targets. Mycolic acids are very long chain fatty acids playing an essential role in the architecture and permeability of the mycobacterial cell wall. Their biosynthesis involves two fatty acid synthase (FAS) systems. Among the four enzymes (MabA, HadAB/BC, InhA and KasA/B) of the FAS-II cycle, MabA (FabG1) remains the only one for which specific inhibitors have not been reported yet. The development of a new LC-MS/MS based enzymatic assay allowed the screening of a 1280 fragment-library and led to the discovery of the first small molecules that inhibit MabA activity. A fragment from the anthranilic acid series was optimized into more potent inhibitors and their binding to MabA was confirmed by F-19 ligand-observed NMR experiments. (C) 2020 Elsevier Masson SAS.
