Synthesis, Cytotoxicity Evaluation, Molecular Docking and Utility of Novel Chalcones as Precursors for Heterocycles Incorporating Pyrazole Moiety

Background: Chalcones, 2-pyrazolines and thiazoles have been reported to possess various pharmacological activities. Objective: Synthesis of new chalcones and utilizing them as a building block for constructing a series of thiazole derivatives and evaluating some of them as anticancer agents. Method: The new compounds were synthesized via stirring at room temperature or thermal heating. Cytotoxic evaluation of the new synthesized compounds was tested using the method of Skehan et al. Moreover, the computational studies were performed using MOE 2014.09 software. Result: A series of new chalcones were prepared by the reaction of ethyl 3-acetyl-1-aryl-5-methyl-1H-pyrazole-4-carboxylate with a number of substituted benzaldehydes. One of these chalcones was used as a building block for constructing a pyrazoline ring via its reaction with thiosemicarbazide. The produced carbothioamide derivative was used for the preparation of two series of thiazole derivatives by its reaction with a number of hydrazonoyl chlorides. Moreover, reaction of 3-acetylpyrazole thiosemicarbazone derivative with a number of N-aryl-2-oxopropane hydrazonoyl chlorides afforded 5-arylazothiazole derivatives. The assigned structures for all the newly synthesized compounds were confirmed on the basis of elemental analyses and spectral data. Some of the newly synthesized chalcones and thiazoles were tested for their cytotoxicity against human colon carcinoma cell line (HCT-116) and the molecular docking was carried out on the most active compound 3f. Conclusion: The results of the anticancer activity revealed that compounds 3f, 3e, 3c and 3b have promising activities compared with the standard drug Doxorubicin. Moreover, the computational studies confirm the results of biological activity. Also, the ADME profile study showed that compound 3f can be considered as a promising drug by conducting good pharmacokinetic and medicinal chemistry tests.

Targeting SARS-CoV-2: Novel Source of Antiviral Compound(s) against COVID-19?

SARS-CoV-2 remains a significant burden on human health. Several lines of evidence suggest that surveillance of sewage and waste can provide an early warning sign for COVID-19 recurrence in a community. In support, SARS-CoV-2 traces were found in sewage in several countries. With this in mind, it is notable that pests, such as cockroaches, are exposed to pathogenic microbes routinely, yet thrive in polluted environments. Such species have likely developed mechanisms to protect themselves against pathogens. In support, recent studies showed that cockroaches possess potent antibacterial molecules to shield themselves from pathogenic bacteria. Among hundreds of molecules, some contained thiazine groups, imidazoles, chromene derivatives, isoquinoline group, sulfonamides, pyrrole-containing analogs, flavanones, and furanones. Here, we propose that cockroaches are a potential source of antiviral molecules to thwart infections. Because this is an unexploited resource for potential antivirals, we believe that cockroaches offer a unique source for novel bioactive molecule(s) to counter COVID-19 with huge clinical impact worldwide.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5460-09-3, you can contact me at any time and look forward to more communication. Recommanded Product: Sodium 4-Amino-5-hydroxy-2,7-naphthalenedisulfonate.

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 147118-35-2, Name is (R)-Methyl 3-((tert-butyldimethylsilyl)oxy)-5-oxo-6-(triphenylphosphoranylidene)hexanoate, belongs to thiazines compound, is a common compound. In a pantent, author is Sirakanyan, Samvel N., once mentioned the new application about 147118-35-2, HPLC of Formula: https://www.ambeed.com/products/147118-35-2.html.

On the reactivity of pyrido[3 ‘,2 ‘:4,5]furo(thieno)[3,2-d]pyrimidin-7(8)-ones with some alkyl mono- and di-halides: synthesis of new heterocyclic systems containing thiazolo[3,2-a]pyrimidine and pyrimido[2,1-b]thiazine moiety

Ethyl 1-aminofuro(thieno)[2,3-b]pyridine-2-carboxylates 1 reacted with benzoyl isothiocyanate and gave the relevant thioureido derivatives 2, whose intramolecular cyclization under the action of potassium hydroxide furnished the relevant 9(10)-thioxopyrido[3′,2′:4,5]furo(thieno)[3,2-d]pyrimidin-7(8)-ones 3. Compounds 3 with methyl iodide could give the S-methyl 4 and S,N-dimethyl 5 derivatives. Interestingly 3 by alkylation with alkyl dichlorides (bifunctional reagents) the cyclization to a thiazoline or to a thiazine ring on the [a] side of the pyrimidine ring occurs, with formation of the new pentacyclic systems: furo(thieno)[3,2-d][1,3]thiazolo[3,2-a]pyrimidin-7(8)-ones 6 and furo(thieno)[3′,2’:4,5]pyrimido[2,1-b] [1,3]thiazin-7(8)-ones 7. Moreover compounds 3 by alkylation with p-chlorophenacyl bromide (again a bifunctional reagent) led to the formation of the corresponding S-alkylated compounds 9, whose cyclization furnished structural analogues of compounds 6: p-chlorophenyl-substituted thiazolo[3,2-a] pyrimidin-7(8)-ones 10. The structure of the obtained compounds has been unambiguously confirmed by using a wide spectrum of physico-chemical methods and, in the instance of compounds 6 and 7, also by an alternative synthesis via a double-annelation reaction using a BMMA reagent. Biological tests have shown promising antimicrobial activity against Staphylococcus aureus for some of the synthesized compounds. (C) 2015 Elsevier Ltd. All rights reserved.

Photocatalytic degradations of three dyes with different chemical structures using ball-milled TiO2

Cibacron Brilliant Red 3B-A (BR 3B-A) was photocatalytically degraded by TiO2 (A) ball milled (BM) at different milling time. TiO2 (A) BM for 2 h (BM2 TiO2 (A)) showed the best photocatalytic degradation efficiency and was utilized to photcatalytically degrade commercial dyes of different chemical nature by breaking down the bond between chloride and the hydrocarbon chain. In the three dyes, i.e., Cibacron Brilliant Red BR 3B-A, Cibacron Brilliant Yellow 3G-P (BY 3G-P), and Astron Pink FG, chloride (Cl) is linked to carbon atom of different conformation. The experimental results suggested that the Cl connected to the aliphatic carbon is much easier and faster to disintegrate than the other two bonding with benzene and thiazine. Production rates of Cl- after 60-min irradiation were 99.7%, 78.1%, and 73.2%, respectively, for Astron Pink FG, BY 3G-P, and BR 3B-A. The changes in the structure characteristics, including the more amorphous surface morphology, the increased specific surface area, the growth in the percentage of high-index crystal faces, etc., were proposed to be the possible reasons for the promoted photocatalytic capability of BM2 TiO2 (A). Ball milling was found a handy approach to modify TiO2 (A) and boost catalytic degradation efficiency of dyes. This research lay out basis for application of photocatalyst in semiconductor industries.
