[PMID: 37307623 DOI: 10.1016/j.ejmech.2023.115548] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 06/03/2023] [Accepted: 06/06/2023] [Indexed: 06/14/2023]
Abstract
A new series of N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) have been synthesized by a cyclo-condensation reaction of 2-bromo-1-(1,3-diphenyl-1H-pyrazol-4-yl)ethanone (6a-f) with N-aryl thiourea, (7a-d). The structure of newly synthesized N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) derivatives was analyzed by 1H NMR, 13C NMR and Mass spectral analysis. The compounds 8a-x were screened for in vitro antimicrobial activity against Escherichia coli, Proteus mirabilis, Bacillus subtilis, Staphylococcus aureus, Candida albicans and Aspergillus niger. and antitubercular activity against M. tuberculosis H37Rv strain. Among the twenty-four pyrazolyl-thiazole derivatives, six compounds 8a, 8b, 8j, 8n, 8o and 8s showed good activity against S. aureus. Against A. niger, all synthesized derivatives showed good antifungal activity. Fifteen pyrazolyl-thiazole derivatives 8a, 8f, 8g, 8h, 8j, 8k, 8n, 8o, 8p, 8q, 8r, 8s, 8t, 8w and 8x showed good antitubercular activity with MIC 1.80-7.34 μM (0.8-3.12 μg/mL), these derivatives have showed more activity than the drugs isoniazid and ethambutol. The active compounds were further screened for cytotoxicity activity against the mouse embryonic fibroblast cells (3t3l1) cell lines at 12.5 and 25 μg/mL concentrations and found less or non-cytotoxicity. To know the plausible mode of action, the synthesized pyrazolyl-thiazole derivatives were studied for pharmacokinetics, toxicity profiles and binding interactions along with an in-depth analysis of structural dynamics and integrity using prolonged molecular dynamics (MD) simulation. The compounds have shown significant docking scores in the range of -7.98 to -5.52 and -9.44 to -7.2 kcal/mol with the M. tuberculosis enoyl reductase (M. tb. InhA) and C. albicans sterol 14-α demethylase (C. ab. CYP51), respectively. Thus, the significant antifungal and antitubercular activity of N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) derivatives incited that, these scaffolds could assist in the development of lead compounds to treat fungal and antitubercular infections.

Abstract
We have synthesized novel pyrazolo-quinoline analogues (P1-10) in an effort to create newer antitubercular drugs against the rising bacterial resistance. NMR, IR and ESI-MS spectra were utilized to characterize the synthesised compounds. The antitubercular activity of the target compounds was evaluated against Mycobacterium tuberculosis. Six derivatives (P1-6) displayed very significant activity at 1.6 µg/mL concentration and were found to be more active than pyrazinamide standard. Thus, as per the drug susceptibility results the MIC value could be considered between 1.6 and 0.8 µg/mL. In addition, all the synthesised compounds were subjected to molecular docking studies against specific protein, Enoyl acyl carrier protein reductase (InhA) in complex with N-(4-methylbenzoyl)-4-benzylpiperidine, PDB ID: 2NSD. Among all the compounds the most effective compounds were found an Autodock score of 11.6 and 11.2 against 2NSD, respectively. Further, Zebrafish larvae have been used to test the teratogenicity of the synthesised compounds. There were no indications of abnormalities with (P2), (P4), (P5), (P6), and (P10) at 0.5 µM.

Abstract
Abstract:
The new series of pyrazolines derivatives containing isoniazid moiety were synthesized from
2-hydroxynaphthyl functionalized chalcones and isoniazid using sodium hydroxide as a base in 2-
ethoxy ethanol. We evaluated their antitubercular activity against Mycobacterium tuberculosis strain
(H37Rv) by Microplate Alamar Blue Assay (MABA). Some of the tested compounds 3a, 3b, and 3c,
were found to have higher antitubercular activity than the selected standard drugs, whereas compounds
3d, 3e, 3i and 3j were found to have higher antitubercular activity than Streptomycin and same as that
of Pyrazinamide and Ciprofloxacin, while remaining compound showed moderate activity. Whereas it
is found that the disubstituted halogen compound and electron-withdrawing group on the phenyl ring
are important substitutions for an increase in antitubercular activity.

Abstract
BACKGROUND Pyrazole scaffolds have gained importance in drug discovery and development for various pharmacological activities like antiviral, antifungal, anticancer, antidepressant, anti-inflammatory, antibacterial, etc. Additionally, the pyrazole moiety has shown potent anti-HIV activity as a core heterocycle or substituted heterocycles derivatives (mono, di, tri, tetra, and fused pyrazole derivatives). To assist the development of further potential anti-HIV agents containing pyrazole nucleus, here we have summarized pyrazole containing anti-HIV compounds that have been reported by researchers all over the world for the last two decades. OBJECTIVE The present review concentrates on an assortment of pyrazole containing compounds, particularly for potential therapeutic activity against HIV. METHODS Google Scholar, Pubmed, and SciFinder were searched databases with ''pyrazol'' keywords. Further, the year of publication and keywords ''Anti-HIV'' filter was applied to obtain relevant reported literature for anti-HIV agents containing pyrazole as a core or substituted derivatives. RESULTS This review article has shown the comprehensive compilation of 220 compounds containing pyrazole nucleus and possessing anti-HIV activity by sorting approximately 40 research articles from 2001 to date. 1-(4-Benzoylpiperazin-1-yl)-2-(4-fluoro-7-(1H-pyrazol-3-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)ethane-1,2-dione (13), 3-(3-(2-(4-benzoylpiperazin-1-yl)-2-oxoacetyl)-4-fluoro-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-pyrazole-5-carboxamide (31), 3-(3-(2-(4-benzoylpiperazin-1-yl)-2-oxoacetyl)-4-fluoro-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-pyrazole-5-carboxamide (88), 3-cyanophenoxypyrazole derivative (130), and 4-(4-chlorophenyl)-5-(4-methyl-5-((4-nitrophenyl)diazenyl)thiazol-2-yl)-3-phenyl-5,6-dihydro-4H-pyrazolo[4,3-d]isoxazole (178) were the most potent mono-, di-, tri-, tetra-substituted, and fused pyrazole derivatives, respectively, which have shown potent anti-HIV activity among all the described derivatives as compared with standard anti-HIV drugs. CONCLUSION This review article provides an overview of the potential therapeutic activity of pyrazole derivatives against HIV that will be helpful for designing pyrazole containing compounds for anti-HIV activity.

Abstract
A facile and efficient one-pot three-component reaction method for the synthesis of thiazine-dicarboxylates is reported. Reaction of an isocyanide and dialkyl acetylenedicarboxylate with 2-amino-4H-1,3-thiazin-4-one derivatives containing both an acidic proton and an internal nucleophile gave the products in good yields of 76-85%. The reactivity of dialkyl acetylenedicarboxylates was further tested in the synthesis of thiazole-pyrimidines where a two-component reaction of 2-aminothiazole with dialkyl acetylenedicarboxylates was successfully converted to a more efficient three-component reaction of a thiourea, α-haloketone and dialkyl acetylenedicarboxylate (DMAD/DEtAD) to give thiazole-pyrimidines in good yields of 70-91%.

Abstract
A total of fourteen pyrazoline derivatives were synthesized through cyclo-condensation reactions by chalcone derivatives with different types of semicarbazide. These compounds were characterized by IR, 1D-NMR (1H, 13C and Distortionless Enhancement by Polarization Transfer - DEPT-135) and 2D-NMR (COSY, HSQC and HMBC) as well as mass spectroscopy analysis (HRMS). The synthesized compounds were tested for their antituberculosis activity against Mycobacterium tuberculosis H37Ra in vitro. Based on this activity, compound 4a showed the most potent inhibitory activity, with a minimum inhibitory concentration (MIC) value of 17 μM. In addition, six other synthesized compounds, 5a and 5c–5g, exhibited moderate activity, with MIC ranges between 60 μM to 140 μM. Compound 4a showed good bactericidal activity with a minimum bactericidal concentration (MBC) value of 34 μM against Mycobacterium tuberculosis H37Ra. Molecular docking studies for compound 4a on alpha-sterol demethylase was done to understand and explore ligand–receptor interactions, and to hypothesize potential refinements for the compound.
