New disazo dyes derived from aminopyrazoles: synthesis, spectroscopic properties, computational study and structural properties

In this study, five new pyrazolyazo pyrazole dyestuff syntheses are reported. For this purpose, 5-amino-4-arylazo-3-methyl-1H-pyrazoles were diazotised and coupled with 3-amino-5-hydroxy-1H-pyrazole. Fourier Transform-infrared, ultraviolet-visible and proton nuclear magnetic resonance spectroscopy were used to investigate the properties of aminopyrazole-based dyes obtained in this study. The maximum absorption wavelengths of these dyes in various solvents were determined. The theoretical calculations of the molecules in the ground state were performed with the density functional theory/Becke 3-parameter and Lee-Yang-Parr/6-311G(d,p) method by using the Gaussian 0.9 W program. The results were compared with the corresponding experimental data. Acid-base and substituent effects on the absorption spectra of dyes were also examined and reported.

Recent advancements in the development of heterocyclic anti-inflammatory agents

Most of the anti-inflammatory drugs in clinical practice are becoming outdated owing to their potential side and adverse effects. These are found to be highly unsafe for long term use. Thus, since last few years, new anti-inflammatory agents are being developed and number of them are in advanced stages of clinical trials. Heterocyclic molecules have gained great attention of chemists due to their similarity to different biological precursors. In the current review, we have highlighted the recent developments (2015 onwards) in designing and synthesis of various heterocyclic anti-inflammatory molecules along with detailed SAR studies. The principal objective of this review is to provide a profound overview of the recently explored heterocyclic anti-inflammatory agents belonging to various classes such as pyrazole, pyrimidine, benzimidazole, indole, and other related heterocyclic compounds. In addition, an enlarged view on potential interactions of synthetic preparations with target inflammatory enzymes or cytokines has been provided. We have also enlisted lead compounds undergoing different clinical trials against inflammation. The elementary aim of this review is to provide restructured knowledge regarding heterocyclic molecules which will be valuable for the scientists working in the field of anti-inflammatory chemistry. The authors believe that lead compounds mentioned in the report will help to design and develop novel anti-inflammatory drug molecules targeting various factors involved in the progression of inflammation.

Antiparasitic Behavior of Trifluoromethylated Pyrazole 2-Amino-1,3,4-thiadiazole Hybrids and Their Analogues: Synthesis and Structure-Activity Relationship

A series of trifluoromethylated pyrazole thiosemicarbazone, trifluromethylated pyrazole isothiosemicarbazone, and trifluoromethylated pyrazole 2-amino-1,3,4-thiadiazole hybrids were synthesized and evaluatedin vitroagainst the promastigote form ofLeishmania amazonensisand the epimastigote form ofTrypanosoma cruzi, the pathogens causing the neglected tropical diseases leishmaniasis and Chagas disease, respectively. The results show the potential of these compounds regarding their antiparasitic properties. Studies on the structure-activity relationship demonstrated that compounds containing a bulky group at theparaposition of the phenyl ring attached to the 5-position of the pyrazole core had better antiparasitic effects. Among the substituents attached at the 3-position of the pyrazole ring, the insertion of the 2-amino-1,3,4-thiadiazole nucleus led to the most potent compounds compared to the thiosemicarbazone derivative.

Study of the in vivo antiviral activity against TMV treated with novel 1-(t-butyl)-5-amino-4-pyrazole derivatives containing a 1,3,4-oxadiazole sulfide moiety

A series of new 1-tert-butyl-5-amino-4-pyrazole bioxadiazole sulfide derivatives containing a 1,3,4-oxadiazole moiety were designed and synthesized. The bioactivity results showed that some title compounds exhibited excellent protective activity against TMV and certain insecticidal activity. Among the tested compounds, the EC50 values of 5d, 5j, 5k and 5l were 165.8, 163.2, 159.7 and 193.1 mg/L, respectively, which are better than the EC50 value of ningnanmycin (271.3 mg/L). The chlorophyll contents and the defense enzyme activities of the tobacco leaves after treatment with 5j were significantly increased, which indicated that this series of title compounds may induce the systemic acquired resistance of host to defend against diseases. Further in vivo protective activity research on 5j using TMV with a GFP gene tag found that it can effectively inhibit the spread of TMV in inoculated tobacco. A morphological study with TEM revealed that title compound 5h can cause a distinct break of the rod-shaped TMV. Moreover, the insecticidal activity revealed that the fatality rates of 5a, 5b and 5m against aphidoidea were 85%, 83% and 87%, respectively, which indicated that the title compounds can effectively block the common carrier of plant viruses, thereby effectively reducing the TMV infection risk of tobacco. This series of synergistic effects provide key information for the research and development of antiviral agents.

Transition-Metal-Free C-S Bond Forming Strategy towards Synthesis of Highly Diverse Pyrazole Tethered Benzothiazoles: Investigation of their Photophysical Properties

A metal-free domino approach has been devised towards construction of two C-S bonds for the synthesis of bioactive N, S-heterocycles. The developed method was extended for the preparation of structurally diverse pyrazole tethered benzothiazole frameworks by using one-pot operation of pyrazole C-3/4/5 carbaldehydes, electron rich aromatic amines and elemental sulfur. This protocol provides excellent fluorophores with several additional advantages such as transition metal-free approach, inexpensive and odorless sulfur source, superior atom economy, and broad substrate scope including gram scale synthesis. The synthesized pyrazole tethered benzothiazole fluorophores were evaluated for their luminescent properties including absorbance, excitation, emission, molar extinction coefficient, brightness, and Stokes shift. The photophysical studies revealed that these pyrazole and benzothiazole hybrids emerged as excellent fluorophores and could exhibit fluorescence quantum yield up to 66%.

Design, synthesis, biological evaluation, and docking studies of some novel chalcones as selective COX-2 inhibitors

A new series of chalcones (1-9) possessing an SO2CH3 COX-2 pharmacophore at the para position of the C-1 phenyl ring was synthesized via the Claisen-Schmidt condensation reaction and examined for their inhibition potential against cyclooxygenase (COX) enzymes. Their structures were elucidated by infrared, H-1 NMR (nuclear magnetic resonance), C-13 NMR, and high-resolution mass spectroscopic methods. Enzyme inhibition studies revealed that most of the compounds showed a moderate-to-strong inhibitory activity (IC50 = 0.18-0.34 mu M) against the COX-2 enzyme as compared with celecoxib (IC50 = 0.12 mu M), ibuprofen (IC50 = 5.33 mu M), and nimesulide (IC50 = 1.68 mu M). Among these compounds, 1-[4-(methylsulfonyl)phenyl]-3-(2,3-dichlorophenyl)prop-2-en-1-one (5), 1-[4-(methylsulfonyl)phenyl]-3-(2,4-dichlorophenyl)prop-2-en-1-one (6), and 1-[4-(methylsulfonyl)phenyl]-3-(2-chloro-6-fluorophenyl)prop-2-en-1-one (8) became prominent with IC50 values of 0.21, 0.19, and 0.18 mu M, respectively. According to molecular docking studies of the most effective compounds, it was found that the compounds interact with amino acids that are important in COX-2 selectivity, such as Arg499 and Phe504.
