A new unsymmetrical N2O2-tetradentate Schiff-base complex of zinc(II) was synthesized by the template reaction of pyridoxal-S-methylthiosemicarbazone and 2-hydroxy-4-methoxy-benzaldehyde as starting compounds. S-methylthiosemicarbazone (1) and zinc(II) complex [Zn(L)CH3OH] ( 2) were characterized by elemental analysis, FT-IR, UV-visible, H-1, and C-13 NMR spectra. The molecular structure of the complex (2) was determined by single crystal X-ray diffraction technique. The structure consists of a distorted square-pyramidal geometry around the central metal, Zn(II). Quantum chemical calculations were carried out using density functional theory DFT/B3LYP, 6-31G (d), and LanL2DZ basis sets for theoretical characterization of the compounds. The experimental and theoretical data were compared comprehensively. The potential energy distribution (PED) analysis was performed for the assignment of vibration frequencies. In order to support in vitro studies, molecular docking studies have been carried out so that the title compound can be an inhibitor of Epidermal Growth Factor Receptor (1 m17), and the relationship between calculated HOMO energies and docking studies has been examined. In addition, the total antioxidant capacity (as TEAC value) and free radical scavenging activity of the compounds were determined by Cupric Reducing Antioxidant Capacity (CUPRAC) and 1,1-diphenyl-2-picryl hydrazyl (DPPH) methods, respectively.

A new imidazo [1,5-alpha]pyridine-based fluorescent probe, named MZC-AC, is developed for the detection of cysteine (Cys) based on an excited state intramolecular proton transfer (ESIPT) mechanism. The probe MZC-AC uses an acrylate moiety as the ESIPT blocking group as well as the recognition site. Upon the treatment with Cys, MZC-AC exhibits a dramatic fluorescence enhancement (85-fold) and a large Stokes shift (166 nm). The limit of detection obtained from fluorescent titration was as low as 0.07 mu M. MZC-AC displays highly sensitive and selective response to Cys over homocysteine (Hcy) and glutathione (GSH). Significantly, MZC-AC could be used to detect Cys in living cells.

A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

The combined influence of structural factors (Y, Z substituents) on the rate of catalyzed by Z-substituted pyridines reactions of phenyloxirane with Y-substituted N-aroylbenzenesulfonamides in acetonitrile at 293 K was studied. A cross-correlation analysis of the results of a multifactor kinetic experiment was carried out. A polylinear regression, that adequately describes the non-additive effects of substituents Y and Z, was calculated. Due to the interaction of the joint effects of structure, the cross-reaction series exhibits isoparametric properties. The mechanism of the catalytic process has been discussed.

Hydrocyanation in the absence of toxic HCN gas is highly desirable. Addressing that challenge, transition-metal-catalyzed transfer hydrocyanation using safe HCN precursors has been developed, but these reagents generally require a Lewis acid for activation, and the control of regioselectivity often remains problematic. In this Letter, a Ni-catalyzed highly Markovnikov-selective transfer hydrocyanation that operates in the absence of any Lewis acid is reported. The readily prepared pro-aromatic 1-isopropylcyclohexa-2,5-diene-1-carbonitrile is used as the HCN source, and the reaction shows a broad substrate scope and high functional group tolerance. Terminal styrene derivatives, dienes, and internal alkynes are converted with good to excellent selectivities. Mechanistic studies provide insights into the origin of the regioselectivity.

Heterocyclic compounds are of particular importance among pharmacologically active compounds. In this study, some piperonyl-based 4-thiazolidinone derivatives (2a-i) were synthesized and characterized by spectroscopic assays. All molecules were tested as enzyme inhibitory factors. These compounds were effective inhibitors of the enzymes acetylcholinesterase (AChE), alpha-glycosidase (alpha-Gly), and the human carbonic anhydrase I and II isoforms (hCA I and II), with K-i values in the range of 8.90-66.51 nM for alpha-Gly, 94.8-289.5 nM for hCA I, 106.3-304.6 nM for hCA II, and 0.55-2.36 nM for AChE. The synthesized molecules were also studied theoretically. Molecular docking calculations were performed to investigate the interaction between the target protein and molecules. CA inhibitor compounds have been clinically used for almost 60 years as antiglaucoma and diuretic drugs. The inhibition of the AChE enzyme results in the blockage of ACh hydrolysis. On the contrary, the design of inhibitor compounds or/and modulators for AChE is of major interest as it is one of the most popular tools to prevent Alzheimer’s disease.

Direct alkylation and arylation of allylic C(sp3)-H bonds are straight-forward approaches for accessing allylic C-C products. However, the engagement of allylic C-C bond- forming reaction without introducing extraneous functional groups and stoichiometric oxidant or reductant has proved difficult. Here, we report a general and mild strategy using semiconductor quantum dots (QDs) as photocatalysts for coupling a broad range of available allylic C(sp(3))-H bonds with alpha- amino C-H bonds or heteroarenes, respectively, under sunlight irradiation (> 85 examples). The protocol bypasses stoichiometric oxidant or reductant and pre-functionalization of both the coupling partners and produces hydrogen (H-2) as the byproduct. The outstanding efficiency and selectivity and step- and atom-economy represents the first direct alkylation and arylation of allylic C(sp(3))-H bonds with hydrogen evolution powered by solar energy.
