A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

Recently I am researching about 1,5-BENZOTHIAZEPINE DERIVATIVES; ANTICANCER; ANTIOXIDANT, Saw an article supported by the Dean’s office of College of Pharmacy and Health Sciences, Ajman University, UAE.

A series of twenty new chloropyrazine conjugated benzothiazepines (22-41) have been synthesized with 58%-95% yields. The compounds were characterized by using different spectroscopic techniques including FT-IR, H-1 NMR, C-13 NMR spectroscopy and mass spectrometry. The synthesized compounds (22-41) and their precursor chalcones (2-21) were evaluated for antitubercular and cytotoxic activities. Additionally, compounds 22-41 were also tested for antimicrobial activity. Among the chalcone series (2-21), compounds 7 and 14 showed significant antitubercular activities (MICs 25.51 and 23.89 mu M, respectively), whereas among benzothiazepines (22-41), compounds 27 and 34 displayed significant antimicrobial (MICs 38.02 mu M, 19.01 mu M) and antitubercular (MIC 18.10 mu M) activities. Compounds 7 and 41 displayed cytotoxic activities with IC50 of 46.03 +/- 1 and 35.10 +/- 2 mu M respectively. All the compounds were evaluated for cytotoxic activity on normal human liver cell lines (L02) and found to be relatively less selective towards this cell line. The most active compounds identified through this study could be considered as potential leads for the development of drugs with possible antimicrobial, antitubercular, and cytotoxic activities.

This paper aimed to provide an insight into the mechanism of transdermal penetration of drug molecules with respect to their physicochemical properties, such as solubility (S), the presence of enantiomer (ET) and logarithm of octanol-water partition coefficient (log P), molecular weight (MW), and melting point (MP). Propionic acid derivatives were evaluated for their flux through full-thickness skin excised from hairless mice upon being delivered from silicone-based pressure-sensitive adhesive (PSA) matrices in the presence or absence of various enhancers. The skin fluxes of model compounds were calculated based on the data obtained using the method engaged with the diffusion cell system. The statistical design of experiments (DoE) based on the factorial approach was used to find variables that have a significant impact on the outcomes. For the prediction of skin flux, a quantitative equation was derived using the data-mining approach on the relationship between skin permeation of model compounds (similar to 125 mg/ml) and involved physicochemical variables. The most influential variables for the skin flux of propionic acid derivatives were the melting point (0.97) followed by the presence of enantiomer (0.95), molecular mass (0.93), log P values (0.86), and aqueous solubility (0.80). It was concluded that the skin flux of molecular compounds can be predicted based on the relationship between their physicochemical properties and the interaction with cofactors including additives and enhancers in the vehicles.

A composite film with multiple anti-counterfeiting features was demonstrated by superposing quantum dots (QDs) polymer matrix (film A) and cholesteric liquid crystal film (film B) together. The first-line and second-line anti-counterfeiting characteristics were successfully implemented by employing thermochromic, angular photochromic, and circularly polarized discoloration of film B, respectively. By initiatively utilizing the different relative positions between the fluorescence emission peak (lambda(em)) of film A and the central selective reflection wavelength (lambda(em)) of film B at different temperatures, which resulted in changes in the fluorescence spectra or the different presence of latent patterns, the most important third-line anti-counterfeiting feature was successfully achieved.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

The morphology and size of Co-MOF-74 were effectively controlled by adjusting the water portion in DMF-H2O mixed solvent system, and six different Co-MOF-74 samples were successfully obtained. The water content can alter the deprotonation rate of the organic ligand and then change the nucleation rate of crystal, thus regulate morphology and size of Co-MOF-74. The discrepancy of morphology and size has significant effect on texture structure of Co-MOF-74 but without changing their composition. The formation mechanism of crystal growth was proposed by studying the change of reaction solution pH value. These samples exhibit morphology and size dependent catalytic activity in toluene oxidation. The flower-like sample has the best catalytic performance with 12.1% toluene conversion and 63.8% benzaldehyde selectivity. Additionally, the influence of reaction parameters on the catalytic oxidation reaction was also examined. Rearserch on the structure-property relationship of catalyst would be useful for rationally synthesizing novel MOF in heterogeneous catalysis.

A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding Ni-II pincer carbene complex, which afforded highly enantioenriched beta-hydroxynitriles. This highly atom-economical process paves the way for exploiting inexpensive acetonitrile as a promising C2 building block in a practical synthetic toolbox for asymmetric catalysis.

Wheat bran, which contains a large amount of cellulose, is used as a raw material to produce soy sauce, but it is hard to degrade during fermentation. Steam explosion (SE) is efficient in hydrolyzing the cellulose for enhancing enzymatic digestion and solvent accessibility. In this study, we applied a SE at a sufficiently high pressure to damage the integrity of the wheat bran structure and modify it to assume a layered form. We found that cellulose, hemicellulose, and lignin structures were collapsed by SE pretreatment, which was indicated by their changes in Fourier transform infrared spectroscopy (FTIR). The amounts of cellulose, hemicellulose, and lignin decreased by 5.8%, 21.4%, and 43.4%, respectively, under 1.5 MPa, resulting in the significant reduction of sugar and amino acid nitrogen. The co-reaction of nonenzymatic browning after SE pretreatment resulted in an intense increase in flavor (overall feeling), as determined by electronic nose analysis and sensory evaluation. In conclusion, SE pretreatment under 1.0 MPa was proven to be the most optimal state for the production of aroma compounds (volatile compounds), which are essential for soy sauce production.

New 2-pyridone derivatives bearing p-methoxyphenyl and p-bromophenyl substituents at C-4 and C-6 were prepared smoothly by the one-pot reaction in high yield, and in a comparatively short time, it reacted with phosphorous oxychloride to produce the corresponding chloro compound. The latter was reacted with several nitrogen nucleophiles such as sodium azide, hydrazine, acetohydrazide, and benzohydrazide to give tetrazolo, hydrazino, and triazolo derivatives, respectively. The reaction of hydrazino derivative with cyclopentanone, furan-2-carbaldehyde afforded the corresponding hydrazone derivatives. Cyclocondensation of the latter compounds with thioglycolic acid afforded the nicotinamide derivatives. 2-Pyridone reacted with ethyl chloroacetate to afford chloroacetate and ethyl acetate derivatives. Ethyl acetate-derivative reacted with hydrazine hydrate and gave the acetohydrazide derivative, it was condensed with p-anisaldehyde and gave the 4-methoxybenzylidene acetohydrazide derivative. Also, 2-pyridone reacted with chloroacetic acid and or benzoyl chloride, afforded the benzoate derivative and 2-((6-(4-bromophenyl)-3-cyano-4-(4-methoxyphenyl) pyridin-2-yl) oxy) acetic acid, respectively. Structures of the products were confirmed using spectroscopic data and elemental analyses. Antibacterial activity of the synthesized compounds was evaluated against Escherichia coli and Staphylococcus aureus.
