2-Acetylbenzimidazole: a Valuable Synthon for the Synthesis of Biologically Active Molecules

Benzimidazole is an important moiety from a medicinal chemistry perspective due to its various biological activities such as antimicrobial, anti-cancer, anti-diabetic, anti-Alzheimers, and anti-inflammatory, etc. 2-acetylbenzimidazole is exploited to obtain various heterocyclic compounds of pharmacological interest. This review’s main motive is to present the literature on 2-acetylbenzimidazole chemistry and provide valuable and up-to-date information for its applications. The present review is carried out by compiling literature from 1964 to 2020 concerning the synthesis and biological aspects of various heterocyclic compounds derived from 2-acetylbenzimidazole. Literature was collected from various online search engines viz. Google Scholar, PubMed, Science Direct, Core, and Semantic scholar. 2-acetylbenzimidazole has been successfully employed as a synthon to obtain heterocyclic system viz. oxirane, pyrazoline, thiazole, pyrazole, isoxazoline, isoxazole, pyridine, pyrimidine, thiazine, diazepine, and other miscellaneous rings. 2-acetylbenzimidazole has shown promise for the convenient synthesis of various heterocyclic compounds. The reactions can be carried out on various reactive sites of 2-acetylbenzimidazole, which are the carbonyl group and the amino group. This review will help to explore various heterocyclic compounds and particularly in the synthesis of biologically useful compounds.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 645-05-6, you can contact me at any time and look forward to more communication. HPLC of Formula: C9H18N6.

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.

Multiple biological active 4-aminopyrazoles containing trifluoromethyl and their 4-nitroso-precursors: Synthesis and evaluation

4-Nitroso-3-trifluoromethyl-5-alkyl[(het)aryl]pyrazoles were synthesized via one-pot nitrosation of 1,3-diketones or their lithium salts followed by treatment of hydrazines. Reduction of nitroso-derivatives made it possible to obtain 4-amino-3-trifluoromethylpyrazoles chlorides. According to computer-aided calculations, all synthesized compounds are expected to have acceptable ADME profile for drug design. Tuberculostatic, antibacterial, antimycotic, antioxidant and cytotoxic activities of the compounds were evaluated in vitro, while their analgesic and anti-inflammatory action was tested in vivo along with acute toxicity studies. N-Unsubstituted 4-nitrosopyrazoles were the most effective tuberculostatics (MIC to 0.36 mu g/ml) and antibacterial agents against Streptococcus pyogenes (MIC to 7.8 mu g/ml), Staphylococcus aureus, S. aureus MRSA and Neisseria gonorrhoeae (MIC to 15.6 mu g/ml). 4-Nitroso-1-methyl-5-phenylpyrazole had the pronounced antimycotic action against a wide range of fungi (Trichophyton rubrum, T. tonsurans, T. violaceum, T. interdigitale, Epidermophyton floccosum, Microsporum canis with MIC 0.38-12.5 mu g/ml). N-Unsubstituted 4-aminopyrazoles shown high radical-scavenging activity in ABTS test, ORAC/AAPH and oxidative erythrocyte hemolysis assays. 1-Methyl-5-phenyl-3-trifluoromethylpyrazol-4-aminium chloride revealed potential anticancer activity against HeLa cells (SI > 1351). The pronounced analgesic activity was found for 4-nitroso- and 4-aminopyrazoles having phenyl fragment at the position 5 in hot plate test. The most of the obtained pyrazoles had a moderate acute toxicity. (c) 2020 Elsevier Masson SAS. All rights reserved.

Iron(ii) coordination pyrazole complexes with aromatic sulfonate ligands: the role of ether

Four novel heteroleptic mononuclear Fe(ii) coordination complexes including 3,5-dimethyl-1-(2 ‘-pyridyl)-pyrazole (DMPP) and aromatic sulfonate ligands were synthesized and characterized using single crystal-XRD, SQUID magnetometry and(57)Fe Mossbauer spectroscopy. The crystal structures of the complexes revealed the unusual coordination of sulfonate groups to Fe(ii) ions, leading to an Fe-N(4)O(2)coordination environment. This specific molecular layout is presumably caused by diethyl ether, which was vapour diffused into the complexation medium to obtain crystalline complexes. Alongside yielding single crystals, diethyl ether also altered the self-assembly process of a usual FeN(6)homoleptic coordination environment. All the complexes remain paramagnetic at all temperatures as suggested by magnetic susceptibility measurements. All are stable in air except [Fe(DMPP)(2)(tos)(2)] which got partially oxidized to Fe(iii) over time as suggested by(57)Fe Mossbauer spectroscopy.

Evaluating the electronic properties of ditopic and hetero-ditopic ligands derived from benzimidazole and pyrazole by C-13 NMR spectroscopy

Huynh’s electronic parameter (HEP) was applied to distinguish the electronic properties of benzimidazole and pyrazole donors in (NN)-N-boolean AND ditopic and (NN)-N-boolean AND’ hetero-ditopic, dinucleating ligands by C-13 NMR spectroscopy of their dipalladium complexes bearing terminal Pr-i(2)-bimy reporter ligands. The C-13(carbene) NMR resonances of the Pr-i(2)-bimy ligand (HEPs) indicate stronger donation of the symmetrical dibenzimidazole compared to that of the dipyrazole with a Delta HEP value of 1.5(4) ppm. Based on this benchmark value, the effect of spacer groups on the electron donation of the mixed benzimidazole-pyrazole ligands was investigated for the first time. The donicity gap between the benzimidazole and pyrazole donors increases with alkylene spacers, but shrinks with the 1,4-phenylene linker, suggesting electronic communication between the two different heterocycles via pi-electron conjugation. Furthermore, these complex probes could also be used to catalyze the direct arylation of pentafluorobenzene, which showed that the unsymmetrically bridged, dinuclear complexes with alkylene linkers are more reactive.

Synthesis of new arylazopyrazoles as apoptosis inducers: Candidates to inhibit proliferation of MCF-7 cells

New 4-arylazo-3,5-diamino-1H-pyrazole derivatives substituted in the 4-aryl ring with the acetyl moiety were designed and synthesized. The antiproliferative activity of the novel arylazopyrazoles was examined against the MCF-7 cell line. Among all target compounds,8b(IC(50)3.0 mu M) and8f(IC(50)4.0 mu M) displayed higher cytotoxicity as compared with the reference standard imatinib (IC(50)7.0 mu M). Further studies to explore the mechanism of action were performed on the most active hit of our library,8b, via anti-CDK2 kinase activity. It demonstrated good inhibitory effects for CDK2 (IC(50)0.24 mu M) with 62.5% inhibition, compared with imatinib. The cell cycle analysis in the MCF-7 cell line revealed apoptosis induction by8band cell cycle arrest at the S phase. Docking in the CDK2 active site and pharmacophore modeling confirmed the affinity of8bto the CDK2 active site. Absorption, distribution, metabolism, and excretion studies revealed that our target compounds are orally bioavailable, with no permeation through the blood-brain barrier.
