A novel one-pot multicomponent reaction to synthesize substituted imidazopyrazines is described. In brief, 1H-(imidazol-5-yl)-N-substituted methanamines react with aldehydes and isocyanides in methanol at room temperature to give imidazopyrazine derivatives in excellent yields. The imidazole nitrogen atom was able to intercept the nascent nitrilium ion, channeling the reaction toward to the sole formation of imidazopyrazines, suppressing the competitive formation of other possible side products deriving from the reaction with the high-energy nitrilium ion. The number of examples and the variability of the nature of isocyanides, aldehydes, and amine components herein employed, witness the robustness of this novel methodology.

An efficient water-based bismuth-mediated addition reaction of carbonyl compound with cyclic allylic halide was developed. The reactions proceeded smoothly in aqueous DMF in the presence of ammonium iodide to afford the corresponding syn-homoallylic alcohols in moderate to good yields with excellent diastereoselectivities (>99:1 syn:anti). Reversal of product diastereoselectivity was observed when heteroaryl aldehyde possessing an adjacent chelating nitrogen atom was employed as substrate. 2019 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

An environmentally benign, robust and straightforward protocol has been developed for the synthesis of a diverse array of 2,3-dihydroquinazolin-4(1H)-ones using 2-aminobenzamide and various aldehydes or ketones. Water, a green solvent was adopted in this methodology replacing hazardous reaction mediums. Further, ascorbic acid, an organocatalyst has been accepted to meet the role of catalyst, thus bypassing the use of noxious metals or hazardous materials, which is another asset of this protocol. The activity of this novel methodology has been further being broadened using an oxidant oxone to synthesize 2-substituted quinazolin-4(3H)-one from aldehyde.

In 2020.0 BIOORG CHEM published article about BIOLOGICAL EVALUATION; INHIBITORY-ACTIVITY; 15-LIPOXYGENASE-1; BIOSYNTHESIS; EXPRESSION; DESIGN; POTENT in [Omar, Yasser M.; Abdel-Moty, Samia G.; Abdu-Allah, Hajjaj H. M.] Assiut Univ, Fac Pharm, Dept Pharmaceut Organ Chem, Assiut 71526, Egypt in 2020.0, Cited 40.0. The Name is 3-Pyridinecarboxaldehyde. Through research, I have a further understanding and discovery of 500-22-1. Formula: C6H5NO

Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.

Herein, a highly stable, porous, multifunctional and metal-free catalyst was developed, which exhibited significant catalytic performance in the oxidation of amines and transfer hydrogenation of nitriles under mild conditions; this could be attributed to the presence of numerous active sites and their outstanding BET surface area. The obtained results showed that most of the yields of imines exceeded 90%, and the cycling performance of the catalyst could be at least seven runs without any decay in the reaction activity, which could be comparable to those of metal catalysts. Subsequently, a kinetic study has demonstrated that the apparent activation energy for the direct synthesis of imines from amines is 67.39 kJ mol(-1), which has been performed to testify that the catalytic performances are rational. Via catalyst characterizations and experimental data, graphitic-N has been proven to be the active site of the catalyst. Hence, this study is beneficial to comprehend the mechanism of action of a metal-free N-doped carbon catalyst in the formation of imines.

The present paper is designed to explore the potential of an important class of heterocycles coumarinylthiazolyl iminothiazolidinone to inhibit jack bean urease. The final products 6a-j were prepared by condensation of substituted aldehydes with intermediate 5 in sodium methoxide/methanol mixture. The synthesized compounds were characterized by their FTIR, H-1, C-13 NMR and mass spectral data. The synthesized coumarinylthiazolyl iminothiazolidinone hybrids 6 a-j were evaluated for their potential to inhibit urease activity. All the synthesized derivatives showed remarkable inhibitory activity with IC50 ranging 8 to 34 nM, while IC50 of standard thiourea is 18.5 nM. The compound 5-(2,4-Dichlorobenzylidene)-2-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl imino) thiazolidin-4-one 6 h bearing 2,4-di-chloro substituted phenyl ring exhibited excellent activity with IC50 value 8 nM. In silico molecular docking studies was performed against urease enzyme PDBID 4H9 M and predicted possible binding modes in catalytic site for these active compounds. The thiazole nitrogen in compound 6 h formed a strong hydrogen bonding interaction with side chain Gln635 having distance 2.01 angstrom and rest part of this inhibitor is present close to Val640. The most potent derivative 6 h have highest binding affinity with binding energy -6.178 kcal/mol. It is concluded based upon our results that 6 a and 6 h are most promising compounds from this series and provide a basis for rationale design of most potent urease inhibitors.
