Sulfamic acid catalyzed synthesis of new 3,5-[(sub)phenyl]-1H-pyrazole bearing N-1-isonicotinoyl: And their pharmacological activity evaluation

A sustainable synthesis of new 3,5-[(sub)phenyl]-1H-pyrazole bearing N-1-isonicotinoyl derivatives from substituted chalcones and isoniazid by using sulfamic acid and their pharmacological activity evaluation is reported. An anti-oxidant study is performed by using DPPH assay. In vitro anti-mycobacterial activity of compounds bearing R/R’ = 4-CH3/4-F and 3-OCH3/4-Cl showed complete inhibition (99%) at the MIC of 31 and 34 mu M respectively. Antibacterial screening of compounds bearing R/R’ = 4-CH3/4-F; 4-OCH3/4-Br; and 4-OCH3/4-Cl has shown noticeable inhibition (27 mm) against Staphylococcus aureus. The anti-cancer bioassay demonstrated that the five compounds were active on human breast cancer cell line MCF-7; however on HeLa cervical cancer cells only two compounds are active in comparison to standard drug Doxorubicin. Higher inhibitory effects observed in this study appear to be dependent on the chloro, bromo, fluoro and methoxy functionality present on the aromatic nucleus. The structures of all the compounds are established using NMR (H-1 and C-13), FT-IR, Mass and elemental analysis.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 4233-33-4. The above is the message from the blog manager. SDS of cas: 4233-33-4.

Effect of oxic/anoxic conditions on the removal of organic micropollutants in the activated sludge process

Among the emerging issues in the field of wastewater treatments, reducing energy consumption and removal of new organic pollutants have become of primary concern. With respect to the first goal, alternating oxic/anoxic conditions in the bioreactor has demonstrated to be a feasible way to ensure the required efficiency of carbon and nitrogen removal along with energy saving. The aim of the present study was to investigate if these alternating oxic/anoxic conditions are also capable of boosting organic micropollutants degradation, by stimulating the appropriate enzymes. Three different aeration frequencies were tested in a laboratory scale activated sludge reactor and the effects evaluated in terms of removal of carbon, nitrogen and a mixture of OMPs (Sulfamethoxazole, Sulfadiazine, Lincomycin, Carbamazepine, Pyrazole, Naproxen, Atrazine and Sucralose). It was also evaluated if these aeration strategies could change the microbial community composition with respect to the control test conducted under continuous air supply. Among the tested strategies, the longest and shortest durations of anoxic conditions promoted the best removal for the majority of OMPs. This enhancement was statistically well correlated to the activity increase of Lignin Peroxidase and Cellulase enzymes whereas the microbial speciation did not change statistically. The same durations were also capable of maintaining high carbon and nitrogen removal rates within the same biological reactor. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis, characterization, X-ray structure and in vitro antifungal activity of triphenyltin complexes based on pyrazole dicarboxylic acid derivatives

A series of new ditriphenyltin(IV) dicarboxylate complexes of general formula (Ph3SnOOC-Pz)(2)R with Pz: pyrazole and R: alkyl or ether, have been synthesized from bipyrazoledicarboxylic acid and hydroxytripheyltin. These complexes, noted C1 C7, have been characterized by IR, H-1 and C-13 NMR spectroscopies. The molecular structures of C3 : 1,3 Bis[(5-methyl-2-H-3-triphenyltincarboxylate pyrazol)]propane and C7: Bis[( 2 methyl-2-H-3-triphenyltincarboxylate pyrazol)ethyl]oxide have been confirmed by single crystal X-ray diffraction. Both compounds crystallize in the monoclinic symmetry: C3 in P2(1) space group with a = 15.915(1) angstrom, b = 10.0791(8) angstrom, c = 13.823(1) angstrom, alpha = 90 degrees, beta = 100.459(3)degrees, gamma = 90 degrees and C7 in P21/n space group, with a = 15.0951(7) angstrom, b = 8.9847(3) angstrom, c = 34.244(1) angstrom, alpha = 90 degrees, beta = 101.421(2)degrees, gamma = 90 degrees. The two cristallographically independent Sn1 and Sn2 atoms are tetra coordinated within distorted tetrahedral environments, very similar in the two compounds. The antifungal activity of these organotin complexes and their corresponding bipyrazoledicarboxylic acid (ligands) has been evaluated against the pathogenic Fusarium oxysporum f. sp. albedinis. This activity greatly depends on the nature of ligands and on the dose used. The presence of triphenyltin moiety improves considerably the antifungal activity becoming close to that of the benomyl (fungicide). (C) 2020 Elsevier B.V. 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.

Effect of Urethane Crosslinking by Blocked Isocyanates with Pyrazole-Based Blocking Agents on Rheological and Mechanical Performance of Clearcoats

A novel blocked isocyanate crosslinker was synthesized, and its applicability was investigated for the low-temperature curing of automotive clearcoats. Various pyrazole derivatives were prepared as blocking agents in isocyanate crosslinkers, which strongly affect the deblocking and curing properties of the urethane-bonded coating systems. The thermal curing properties of clearcoat samples containing a pyrazole-based blocked isocyanate crosslinker and polyol resin were characterized under two different temperature conditions (120 and 150 degrees C). The decrease in the amount of hydroxyl groups in the polyol before and after curing was expressed by the change in OH stretching frequency in the Fourier transform infrared (FT-IR) spectra. The real-time rheological storage moduli of the bulk clearcoat mixtures were measured via a rotational rheometer to determine the effect of pyrazole-based blocking agents on the curing dynamics. In addition, a rigid-body pendulum tester (RPT) was employed to investigate the curing behavior in the thin film form. The nano-indentation and the nano-scratch tests were conducted to examine the surface hardness and scratch resistance characteristics of the cured clearcoat films. The results show that a low-temperature curing system of clearcoats can be realized by tuning the curing temperature and reactivity of isocyanate crosslinkers blocked with pyrazole-based substituents.

Improving iodine adsorption performance of porous organic polymers by rational decoration with nitrogen heterocycle

Four kinds of porous aminal-linked organic polymers (PAOPs) were synthesized via one-step condensation between cheap melamine and respective aldehydes decorated with different nitrogen heterocycle, to evaluate the influence of nitrogen heterocycle on the adsorption performance of target polymer toward iodine. Though having the smallest surface area of 209.9 m(2)/g, PAOP-4 decorated with pyridine group exhibits an adsorption capacity of 108 wt% (iodine/adsorbent weight%), surpassing other three PAOPs with Brunauer-Emmett-Teller area varying from 305.8 to 533.0 m(2)/g. Based on Raman spectral analyses, the characteristic band of I(3)(-)and I(5)(-)was used to evaluate the electronic interaction between iodine and the nitrogen heterocycle, giving an order of pyridine > tetrazole > pyrazole > imidazole. This manifests the vital role of chemical interaction playing in the iodine adsorption by PAOP-4, which is much helpful for designing high-performance organic adsorbent toward iodine.
