Copper borate (CuB 4O 7)-promoted multi-component green synthesis of 2,4,5-triarylimidazole derivatives and evidence of in situ conversion of copper borate (CuB 4O 7) into Cu(OAc) 2 in the presence of NH 4OAc. RSC Adv 2023; 13:19846-19855. [PMID: 37409029 PMCID: PMC10318610 DOI: 10.1039/d3ra03183g] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Accepted: 06/19/2023] [Indexed: 07/07/2023] Open
Abstract
A green, efficient, and straightforward methodology for the three-component synthesis of 2,4,5-triarylimidazole has been developed under solvent-free conditions using unconventional CuB4O7 as a promoter. This green approach encouragingly provides access to a library of 2,4,5-tri-arylimidazole. Also, we have been able to isolate the compound (5) and (6) in situ, which provides an insight into the direct conversion of CuB4O7 into copper acetate in the presence of NH4OAc under solvent-free condition. The main advantage of this protocol includes an easy reaction procedure, short reaction time, and easy work up of the product without using any tedious separation method.

Abstract
Background:
Second generation or “atypical” antipsychotics demonstrate an improved
therapeutic profile over conventional neuroleptics. These are effective in both positive and negative
symptoms of the disease and have a lower propensity to induce adverse symptoms.
Objective:
The main objective of the research was in silico design and synthesis of potential atypical
antipsychotics with combined antiserotonergic / antidopaminergic effect.
Methods:
A one pot synthesis of aryl substituted imidazole derivatives was carried out in green
solvent PEG-400 and the prepared compounds were evaluated for atypical antipsychotic activity in
animal models for dopaminergic and serotonergic antagonism. The compounds were designed
based on their 3D similarity studies to standard drugs and in silico (docking studies) with respect to
5-HT2A and D2 receptors.
Results:
Results from the docking studies with respect to 5-HT2A and D2 receptors suggested a potential
atypical antipsychotic profile for the test compounds. Theoretical ADME profiling of the
compounds based on selected physicochemical parameters suggested an excellent compliance with
Lipinski’s rules. The potential of these compounds to penetrate the blood brain barrier (log BB) was
computed through an online software program and the values obtained for the compounds suggested
a good potential for brain permeation. Reversal of apomorphine induced mesh climbing behaviour
coupled with inactivity in the stereotypy assay indicates antidopaminergic effect and a potential
atypical profile for the test compounds 1-5. Further, the activity of compounds in DOI assay
indicated a 5-HT2 antagonistic profile (5-HT2 antagonism).
Conclusion:
Compound 5 emerged as important lead compound showing combined antidopaminergic
and antiserotonergic (5-HT2A) activity with a potential atypical antipsychotic profile.

Abstract
BACKGROUND SO3H-functionalized zeolite-Y was prepared and used as a catalyst for the synthesis of 2-aryl-N-benzimidazole-4-thiazolidinones and tri-substituted imidazoles at ambient conditions. OBJECTIVE The goals of this catalytic method include excellent yields and high purity, inexpensive procedure and ease of product isolation, the use of nontoxic and heterogeneous acid catalyst, shorter reaction times and milder conditions. MATERIALS AND METHODS NMR spectra were recorded on Brucker spectrophotometer using Me4Si as internal standard. Mass spectra were recorded on an Agilent Technology 5975C VL MSD with tripe-axis detector. FTIR spectra were obtained with KBr disc on a galaxy series FT-IR 5000 spectrometer. The surface morphology of nanostructures was analyzed by FE-SEM (EVO LS 10, Zeiss, Carl Zeiss, Germany). BET analysis were measured at 196 °C by a Japan Belsorb II system after the samples were vacuum dried at 150°C overnight. RESULTS The NSZ was characterized by FT-IR, FESEM, EDX, XRF, and BET. The catalytic activity of NSZ was investigated for synthesis of 1,3-tiazolidin-4-ones in H2O/Acetone at room temperature. Moreover, NSZ was used for synthesis of tri-substituted imidazoles at 60 °C via solvent-free condensation. Different kinds of aromatic aldehydes were converted to the corresponding of products with good to excellent yields. CONCLUSION Sulfonated zeolite-Y was as an efficient catalyst for the preparation of N-benzimidazole-2-aryl-1,3- thiazolidin-4-ones and 2,4,5-triaryl-1H-imidazoles. High reaction rates, elimination toxic solvent, simple experimental procedure and reusability of the catalyst are the important features of this protocol.

Abstract
The α-amino phosphonates exhibit a wide range of biological properties which create demand for simple and efficient synthetic routes of new molecules. In this study synthesis of a new series of derivatives of α-amino chromone phosphonates (ACPs) was reported using RhBT catalyst. The RhBT was first prepared by simply mixing boron nitride in a solution of rhodium acetate, under inert atmosphere for a week followed by filtration (yield: 92%). The catalyst can be re-used for up to four times and showed minimal loss of activity. The ACPs was prepared in a one pot reaction containing chromone based aldehydes, aniline derivatives and diethyl phosphite. The structures of these compounds were characterized by IR, 1H NMR, 13C NMR, 31P NMR and high resolution mass spectral analysis. The synthesized ACPs were evaluated for their antimicrobial activities against three bacteria B. cereus, M. luteus, E. coli and one fungus C. albicans. The ACPs displayed selective toxicity toward the brine shrimp (Artemia salina). Compounds 8j and 8m was found to be less toxic to the brine shrimp and may have more valuable biological application. Furthermore, molecular docking studies were conducted to predict the possible therapeutic potential of ACPs. The compounds (8i, 8j, 8k and 8m) were predicted as highly active HIV-1 reverse transcriptase inhibitors.

Abstract
Syntheses of a new series of biologically potent α-aminophosphonates were accomplished by one-pot Kabachnik-Fields reaction using TiO2-SiO2 as solid supported catalyst under microwave irradiation conditions. The chemical structures of all the newly synthesized compounds were confirmed by analytical and spectral (IR, 1H, 13C, 31P NMR, and mass) data. Their anticancer nature was evaluated by screening the in vitro activity on two human cancer cell lines, HeLa and SK-BR-3. Compounds 4i and 4o showed the best activity on these cancer cells even though the majority of the compounds, and particularly 4l and 4p, have good cytotoxic activity against them.
