In a document, author is Karrouchi, Khalid.

(E)-N’-(2,4-dichlorobenzylidene)-5-phenyl-1H-pyrazole-3-carbohydrazide (E-DPPC) has been synthesized and characterized by FT-IR, H-1-NMR, ESI-MS, and single-crystal X-ray diffraction. The structures and properties of this new pyrazole-3-carbohydrazide derivative were studied in gas phase and aqueous solution by using Functional hybrid B3LYP/6-311++G** calculations in gas phase and in aqueous solution to study. Two stable structures (C1 and C2) with similar energies were found in the PES. C2 evidence a higher dipole moment and a volume contraction in solution attributed to the presence of donors and acceptors H bonds. Besides, the changes in orientation and direction of dipole moment vector in solution are attributed to the hydration of E-DPPC with water molecules. The repulsion existent between the negative MK, Mulliken and NPA charges on the N12 and 015 atoms explain the diminishing of N12-C14-015 angle from 123.77 degrees in gas phase to 123.03 degrees in solution. Nucleophilic sites are visibly observed on the acceptor H bonds groups (N10, 015 and N22 atoms) while on the N18-H21, N12-H13, C11-H23, C2-H3, C17-H20 bonds characteristics electrophilic sites were found, being the N18-H21 bond the most labile donor of H bond with the lowest MEP and bond order values. NBO calculations suggest that C2 is clearly most stable in solution than in gas phase. AIM studies show that C2 is stable in both media due to new H bonds formed. Harmonic force fields in both media were calculated together with the scaled force constants while the 102 vibration normal modes expected for C2 were completely assigned. The comparisons of experimental NMR and UV-visible spectra with the corresponding predicted evidence reasonable correlations. Docking results also displayed that E-DPPC possessed good binding profile against receptor molecule and interacted with core residues of target protein. (C) 2020 Elsevier B.V. All rights reserved.

Copper(II) complexes containing N ‘-aromatic group substituted N,N ‘,N-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)amines: Synthesis, structures, polymerization of methyl methacrylate and ring opening polymerization of rac-lactide

A series of Cu(II) complexes, [LnCuCl2] (L-n = L-A-L-F), supported by N’-aromatic-group-substituted N,N-bis ((3,5-dimethyl-1H-pyrazol-1-yl)methylamine ligands have been synthesized. Variations of substituents at the ortho position of the aniline moiety influenced the solid-state structures of these complexes. The X-ray structures of [LnCuCl2] (L-n = L-A-L-C and L-F) revealed that ligands are coordinated in a N,N,N-tridentate fashion to Cu(II) center and adopted a distorted square-pyramidal geometry, while [LDCuCl2] with N,N-bidentate coordination adopts distorted tetrahedral geometry. These complexes were capable of polymerizing methyl methacrylate (MMA) in the presence of modified methylaluminoxane (MMAO), with [LFCuCl2] displaying the highest activity (2.81 x 10(4) g PMMA (mol Cu)(-1)h(-1)). Regardless of ligand architecture, syndio-enriched PMMAs have been furnished with a slightly broader polydispersity index (PDI). Additionally, the in situ generated dimethyl derivatives, polymerized rac-LA and furnished PLA with mediocre heterotacticities at room temperature. Importantly, the catalytic efficiencies of the Cu(II) complexes studied have been found to be influenced by the steric and electronic properties of ligand. (C) 2020 Elsevier Ltd.

2D-QSAR Modeling and Molecular Docking Studies on 1H-Pyrazole-1-carbothioamide Derivatives as EGFR Kinase Inhibitors

Epidermal growth factor receptor (EGFR) kinase has been commonly associated with cancers such as lung, ovarian, hormone-refractory prostate, metastatic colorectal, glioblastoma, pancreatic, and breast cancers. A series of 1H-pyrazole-1-carbothioamide derivatives and their EGFR inhibitory activities were subjected to two-dimensional (2D) quantitative structure-activity relationship (2D-QSAR) studies. The 2D-QSAR models were constructed based on a forward selection of partial least-squares (PLS) and stepwise multiple linear regression (SW-MLR) methods validated by leave-one-out (LOO) and external test set prediction approaches. The stepwise multiple linear regression (SW-MLR) method presented an encouraging result as compared to other methods. The results of the study indicated that the activity of 1H-pyrazole-1-carbothioamide derivatives as an EGFR kinase inhibitor was more influenced by adjacency distance matrix descriptors. The models were improved after outlier removal through the applicability domain. Based on the resultant models, 11 new compounds with high potency were designed as EGFR kinase inhibitors. Molecular docking studies were performed for designing compounds, and they were compared with erlotinib as a reference to predict their interactions in the active site and identify structural features necessary for producing biological activities.

Quinoline-Pyrazole Scaffold as a Novel Ligand of Galectin-3 and Suppressor of TREM2 Signaling

Galectin-3 has been identified as a critical player in driving the neuroinflammatory responses in Alzheimer’s disease (AD). A key feature of this function of galectin-3 is associated with its interaction with the triggering receptor expressed on myeloid cells-2 (TREM2). Herein, we report a high-throughput screening (HTS) platform that can be used for the identification of inhibitors of TREM2 and galectin-3 interaction. We have utilized this HTS assay to screen a focused library of compounds optimized for the central nervous system (CNS)-related diseases. MG-257 was identified from this screen as the first example of a small molecule that can attenuate TREM2 signaling based on its high affinity to galectin-3 (endogenous ligand of TREM2). Remarkably, MG-257 reduced the levels of proinflammatory cytokines in activated microglial cells, which highlights its ability to inhibit the neuroinflammatory response associated with AD.

Study on the Reaction of Acetone Cyanohydrin with 3,5-Dimethyl-N-alpha,beta-unsaturated Acyl Pyrazole

Cyano compounds are a class of organic compounds with great value. Two different kinds of reactions have been reported using acetone cyanohydrin as reagent and substituted 3,5-dimethyl-N-alpha,beta-unsaturated acyl pyrazole as substrate. The reaction pathway depends on the basic catalysts used when aromatic substituted 3,5-dimethyl-N-alpha,beta-unsaturated acyl pyrazole was used as the substrate. Michael addition reaction occurred in the presence of MgBu 2 with the product yield up to 95%, while alcoholysis reaction of amide occurred in the presence of 1,1,3,3-tetramethvlguanidine (TMG), producing beta-substituted phenyl cyanoacrylates with 84% yield. However, fatty substituted 3,5-dimethyl-N-alpha,beta-unsaturated acyl pyrazole and acetone cyanohydrin underwent Michael addition reaction in the presence of MgBu2 or TMG, the product yield was up to 99%. The possible reaction mechanism when using different basic catalysts was discussed.
