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.

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.

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.

Chemoselective synthesis of 3-trifluoromethylpyrazole-deoxybenzoin hybrids

A simple method of the synthesis of alpha-(3(5)-trifluommethylpyrazol-5(3)-yl)-2-hydroxydeoxybenzoins by a chemoselective reaction of 2-(1,1,1-trifluoroacetonyl)chromones with hydrazine dihydrochloride was developed. This approach involves the initial attack of hydrazine at the carbonyl atom of the CF3C(O)CH2 group followed by the chromone ring opening at C-2 atom and subsequent cyclization to pyrazoles. Such synthetic strategy provides easy access to the novel type of pharmaceutically attractive 3-(trifluomethyl)pyrazole-deoxybenzoin hybrids in high yields.

Coinage metal metallacycles involving a fluorinated 3,5-diarylpyrazolate

Copper(I) and silver(I) pyrazolate complexes {[3,5-(3,5-(CF3)(2)Ph)(2)Pz]Cu}(3) and {[3,5-(3,5-(CF3)(2)Ph)(2)Pz]Ag}(3) have been synthesized using the fluorinated 3,5-(diaryl)pyrazole 3,5-(3,5-(CF3)(2)Ph)(2)PzH and copper(I) oxide and silver(I) oxide, respectively. The gold(I) analog was obtained from a reaction between Au(THT)Cl and [3,5-(3,5-(CF3)(2)Ph)(2)Pz]H/NaH. The X-ray crystal structures show that the coinage metal complexes {[3,5-(3,5-(CF3)(2)Ph)(2)Pz]M}(3) (M = Cu, Ag, Au) are trinuclear in the solid state. They feature distorted nine-membered M3N6 metallacyclic cores. The M-N distances follow Cu o Au o Ag, which is the trend expected from covalent radii of the corresponding coinage metal ions. The 3,5-(3,5-(CF3)(2)Ph)(2)PzH forms hydrogen bonded trimers in the solid state that are further organized by p-stacking between aryl rings. Solid samples of {[3,5-(3,5-(CF3)(2)Ph)(2)Pz]M}(3) display blue photoluminescence. The copper complex {[3,5-(3,5-(CF3)(2)Ph)(2)Pz]Cu}(3) is an excellent catalyst for mediating azide-alkyne cycloaddition chemistry.

Aggregation induced emission (AIE)-active N-arylated ferrocenyl pyrazole-based push-pull chromophores: Structural, photophysical, theoretical and effect of substitution on second-order non-linear optical properties

In this study, we report the synthesis and structural characterization of N-arylated ferrocenyl pyrazole [Fc-Pz-(CF3)-C6H5-R] (R = CH3, 1; OCH3 2), where Pz = pyrazole and Fc = ferrocenyl = Fe(eta(5)-C5H5)(eta(5)-C5H4) chromophores with D-pi-A-pi-D system. The solvatochromic behaviour of compounds 1 and 2 was investigated in various solvents from non-polar to polar. When solvent polarity increases, the charge transfer process produces the more polarized excited state, and consequently, positive solvatochromism was observed. The emission performance of the compounds is weak luminescence in CH3CN solution but becomes high emissive in a mixture of water/CH3CN fraction at (f(w)) 90%, demonstrating aggregation-induced emission (AIE) characteristics, and the mechanism of AIE has been attributed to restricted intramolecular rotation (RIR) process. The time-resolved fluorescence lifetime studies have been demonstrated in water/CH3CN mixture at 90%, as it shows three relaxation pathways in their fluorescence decay. In addition, density functional theory calculations have been employed to optimize the geometry of the molecules, followed by computation of dipole moment (mu), first hyperpolarizability (beta) using various functionals (B3LYP, long-range corrected CAM-B3LYP and LC-BLYP) and frontier molecular orbital levels for understanding the charge transfer, electrochemical and non-linear optical (NLO) properties. The second-order non-linear optical properties were studied by hyper-Rayleigh scattering (HRS) technique using an incident wavelength at 1064 nm. The chromophores exhibited the first hyperpolarizability (beta(HRS) = 38.6 x 10(-30) e.s.u. for 1 and beta(HRS) = 116.8 x 10(-30) e.s.u. for 2) and were found to be 6.8 times greater than that of the reference material, p-nitroaniline (pNA) (beta(HRS) = 17.1 x 10(-30) e.s.u.). Also, compound 2 shows higher NLO effect because the presence of -OCH3 group makes effective charge transfer process by mesomeric effect (+M).

Synthesis, biological activities, and SAR studies of novel 1-(2-chloro-4,5-difluorophenyl)-1H-pyyrazole derivatives

In order to search for the new ryanodine receptor (RyR) regulator, a series of 35 novel fluoro-substituted compounds introduced 1-(2-chloro-4,5-difluorophenyl)-1H-pyrazole moiety containing modified pyrazole heterocycle were designed and synthesized. Then, they were tested for the insecticidal activities against Mythimna separata and Plutella xylostella in our greenhouse. After a systematic biological screening, it was found out that I/c showed 50% larvicidal activities against Mythimna separata at 0.1 mg L-1, equivalent to that of chlorantraniliprole (36%, 0.1 mg L-1). The activity of I/c against Plutella xylostella was 90% at 10(-5) mg L-1, whereas the chlorantraniliprole was 70% at the same concentration. Then, insect electrophysiology experiments were conducted to study the pattern of action of I/c and I/e. It was confirmed by the experimental results that both compounds could lead to the release of calcium from the endoplasmic reticulum of neurons as classical anthranilic diamide insecticides.

Bright NIR-luminescent Nd3+ complexes with pyrazole-substituted 1,3-diketones demonstrated an unusual spectral lines branching ratios

A series of novel highly NIR-emitting Nd3+ complexes with specially designed 1,3-diketones bearing a pyrazole moiety and a linear CxF2x+1 group (x = 1, 3,6) was obtained and exhaustively investigated. It was demonstrated that for the complexes with an increased number of fluorine atoms, the triplet level energy of the ligands is decreased and phonon relaxation processes are suppressed. This provides a remarkable increase in the photoluminescence quantum yield up to 1.1%, which is close to the highest values reported for Nd3+ complexes with 1,3-diketones. The photoluminescence spectra of the complexes exhibited the Stark splitting indicative of non-cubic symmetry. Low symmetry of coordination environment was confirmed by the X-ray structural data and analysis of calculated Judd-Ofelt intensity parameters. Besides, it was revealed that the most intense band in the PL spectrum is attributed to the F-4(3/2) -> I-4(9/2) transition (at 880 nm) which is commonly rather weak for simple diketonate complexes. The calculations showed that the unexpectedly high branching ratio of the F-4(3/2) -> (4)I9/ transition raises with elongation of the fluorinated chain and reaches 59% for the complex with x = 6. The studies were conducted for solutions of the complexes as well as for solid samples, and the corresponding changes in their optical behavior were discussed. Uncommon properties of the synthesized Nd3+ complexes make them promising materials for various state-of-the-art luminescent applications, e.g., luminescent markers with an unusual spectral intensity distribution. Based on the electroluminescence studies, we also estimated the potential of the complexes for purely NIR-emitting OLEDs fabrication.
