Synthesis and photophysical properties of N-styrylazinones

(Chemical Equation Presented) N-Styrylazinones and 1-styrylbenzotriazine were synthesized, and their photophysical properties were investigated. (Z)- and/or (E)-N-Styrylazinones (or azine) 4 were prepared from the corresponding heterocycles 1 and benzaldehyde (3) by four methods. The absorption maxima of (Z)- and/or (E)-4a – 4j were measured in four solvents. Their absorption maxima showed a moderate dependence upon solvents. The absorption maxima of (Z)-isomers were blue-shifted as compared the corresponding (E)-isomers. Emission maxima, fluorescence band half-widths, 0,0 transition energies, Stokes shifts, and quantum yields of (Z)- and/or (E)-4a, 4b, 4d, 4e and 4j were measured in organic solvents. The fluorescence spectra show moderate solvatochroism. The fluorescence properties of N-styrylheterocycles vary with every heterocycles.

An efficient and eco-friendly synthesis, computational assay and antimicrobial evaluation of some novel diastereoselective monocyclic cis-beta-lactams

This paper outlines the efficient and eco-friendly synthesis of twenty monocyclic cis-beta-lactam derivatives, their spectral analysis, X-ray crystallographic study, computational analysis and antimicrobial activity assay. This is the first time that, 2-methoxy carbonyl DCPN has been used as an activator of acid to generate in situ ketene in synthesis of beta-lactams. The synthesis of beta-lactam derivatives was completely diastereoselective leading to the formation of cis-stereoisomers exclusively. All these novel cis-beta-lactam derivatives were fully characterized by FT-IR, 1H NMR, 13C NMR, HRMS, CHNS and X-ray crystallography study. we use quantum chemical analysis on selected derivatives from both the series to explore their potential optical and nonlinear optical (NLO) properties by calculating their absorption energies and third-order NLO polarizability, respectively. The third-order NLO polarizability values for derivatives 5ad and 5bd (with NO2 fragments) are found to be as large as 205.05 ¡Á 10?36 and 203.88 ¡Á 10?36 esu, respectively, which are about 10 times larger than that of p-NA (a prototype NLO molecule). The calculation of frontier molecular orbitals (FMOs) and molecular electrostatic potential (MEPs) maps indicates the intramolecular charge process as origin of larger NLO amplitudes. Additionally, all this novel compound was also evaluated for their antimicrobial activities against certain strains of bacteria and fungi. These derivatives displayed, comparatively good to moderate activity against selected microbial strains. Thus, it is believed that the present newly synthesized monocyclic cis-beta-lactam derivatives are multifunctional in nature and prove to be very important in material science and chemistry.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 932-22-9, help many people in the next few years.category: pyridazine

Biological evaluation and molecular docking studies of synthesized 5-substituted-2-chlorophenyl-4-chloro derivatives bearing pyridazinone moiety

Chemical modification of pyridazinone may lead to a potent therapeutic agent. In this study, biological properties of pyridazinone derivatives were evaluated by assessing their antimicrobial and in-vitro antioxidant activities. The reaction of a mucochloric acid and 3-chloro-phenylhydrazine hydrochloride led to the formation of 5-aryl-4-chloro-2-(3-chloro-phenyl)-2H-pyridazin-3-one derivatives 2(a-j). The target compounds were synthesized using nucleophilic substitution reaction. In-silico molecular docking studies of the synthesized compounds were carried out with the help of V-Life Science MDS 4.6 software using GRIP batch docking method to find out which derivative had a better docking. The newly synthesized compounds were characterized by FTIR,1HNMR,13C-NMR, MS, and elemental analysis. Antimicrobial and in-vitro antioxidant activity study of the novel synthesized compounds were screened. Compounds 2f and 2g showed good antimicrobial having an MIC 12.5 mug/mL against Staphylococcus aureus and Candida albicans and in-vitro antioxidant activities having an IC50 50.84. The experimental results were further supported by molecular docking analysis with better interaction patterns.

N-phenyl-4-pyrazolo[1,5-6]pyridazin-3-ylpyrimidin-2-amines as potent and selective inhibitors of glycogen synthase kinase 3 with good cellular efficacy

Glycogen synthase kinase 3 regulates glycogen synthase, the rate-determining enzyme for glycogen synthesis. Liver and muscle glycogen synthesis is defective in type 2 diabetics, resulting in elevated plasma glucose levels. Inhibition of GSK-3 could potentially be an effective method to control plasma glucose levels in type 2 diabetics. Structure-activity studies on a N-phenyl-4-pyrazolo[1,5-b]pyridazin-3-ylpyrimidin-2-amine series have led to the identification of potent and selective compounds with good cellular efficacy. Molecular modeling studies have given insights into the mode of binding of these inhibitors. Since the initial leads were also potent inhibitors of CDK-2/CDK-4, an extensive SAR was performed at various positions of the pyrazolo[1,5-b] pyridazin core to afford potent GSK-3 inhibitors that were highly selective over CDK-2. In addition, these inhibitors also exhibited very good cell efficacy and functional response. A representative example was shown to have good oral exposure levels, extending their utility in an in vivo setting. These inhibitors provide a viable lead series in the discovery of new therapies for the treatment of type 2 diabetes.
