Synthesis, Molecular Docking Screening and Anti-Proliferative Potency Evaluation of Some New Imidazo[2,1-b]Thiazole Linked Thiadiazole Conjugates

Background: Imidazo[2,1-b]thiazole scaffolds were reported to possess various pharmaceutical activities. Results: The novel compound named methyl-2-(1-(3-methyl-6-(p-tolyl)imidazo[2,1-b]thiazol-2-yl)ethylidene)hydrazine-1-carbodithioate 3 acted as a predecessor molecule for the synthesis of new thiadiazole derivatives incorporating imidazo[2,1-b]thiazole moiety. The reaction of 3 with the appropriate hydrazonoyl halide derivatives 4a-j and 7-9 had produced the respective 1,3,4-thiadiazole derivatives 6a-j and 10-12. The chemical composition of all the newly synthesized derivatives were confirmed by their microanalytical and spectral data (FT-IR, mass spectrometry, H-1-NMR and C-13-NMR). All the produced novel compounds were screened for their anti-proliferative efficacy on hepatic cancer cell lines (HepG(2)). In addition, a computational molecular docking study was carried out to determine the ability of the synthesized thiadiazole molecules to interact with active site of the target Glypican-3 protein (GPC-3). Moreover, the physiochemical properties of the synthesized compounds were derived to determine the viability of the compounds as drug candidates for hepatic cancer. Conclusion: All the tested compounds had exhibited good anti-proliferative efficacy against hepatic cancer cell lines. In addition, the molecular docking results showed strong binding interactions of the synthesized compounds with the target GPC-3 protein with lower energy scores. Thus, such novel compounds may act as promising candidates as drugs against hepatocellular carcinoma.

An enzyme-free DNA circuit-assisted MoS2 nanosheet enhanced fluorescence assay for label-free DNA detection

A fluorescence strategy for highly sensitive and selective detection of H5N1 DNA was proposed based on MoS2 nanosheets and catalytic hairpin assembly. This platform not only avoided any labeling but also reduced the background signal. In the absence of target, CHA could not be triggered and the thiazole orange and MBs complexes were adsorbed on the surface of MoS2 to quench the fluorescence of TO, resulting in low background signal. However, upon addition of target DNA, the CHA was initiated and produced plenty of MBs duplex which could be far away from the surface of MoS2 and bind to TO to enhance its fluorescence. This approach exhibited excellent sensitivity and specificity for H5N1 DNA with a detection limit of 7.5 pM, and realized the assay of H5N1 DNA in human serum samples. Furthermore, this platform could be expanded to detect other virus DNA by changing the corresponding molecular beacons, holding the potential of clinical application.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 121-66-4 is helpful to your research. COA of Formula: C3H3N3O2S.

Rapid oxidation of histamine H-2-receptor antagonists by peroxymonosulfate during water treatment: Kinetics, products, and toxicity evaluation

Peroxymonosulfate (PMS) is an appealing oxidant for organic contaminant destruction relying on radical generation after activation. Herein, we report PMS-promoted rapid degradation of histamine H-2-receptor antagonists (HRAs) through non-radical process for the first time. Five commonly used HRAs, i.e., ranitidine (RNTD), cimetidine (CMTD), famotidine (FMTD), nizatidine (NZTD) and roxatidine (RXTD), were examined their reactivity towards PMS. Results show that HRAs (except RXTD) exhibit high reactivity towards PMS, with apparent second-order rate constants from 403 to 872 M(-1)s(-1) at pH 7.0. Radical scavenging experiments excluded the contribution of radicals to PMS-promoted degradation of HRAs, and this non-radical process was unaffected by the real water matrices. Structure-activity assessment and theoretical calculation indicated that the thioether sulfur in HRAs (except RXTD) was the main reactive site for PMS oxidation. Transformation product analysis further elucidated oxidation of the thioether sulfur to sulfoxide product through an oxygen atom transfer process. Moreover, the thioether sulfur on the straight chain was more susceptible to oxygen transfer with PMS than that on the thiazole ring of HRAs. Toxicity evaluation indicated the ecotoxicity of HRAs could be remarkably reduced after PMS oxidation. Hence, this work provides a promising strategy to rapidly remove HRAs and significantly reduce their toxicity in water treatment. (C) 2020 Elsevier Ltd. All rights reserved.

Novel approach of multi-targeted thiazoles and thiazolidenes toward anti-inflammatory and anticancer therapy-dual inhibition of COX-2 and 5-LOX enzymes

It is well established that cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) play a vital role in the initiation and progression of inflammatory reactions. Hence, thiazole and thiazolidene-based pharmacophore molecules were synthesized to obtain dual COX-2 and 5-LOX inhibitory activity. The synthesis of target compounds has been achieved by a novel green strategy. In vitro COX-1, COX-2, and 5-LOX evaluation of these molecules have shown the potential for an improved anti-inflammatory profile. Most promising compound among the series (2-(diphenylamino)-4-(4-nitrophenyl)thiazol-5-yl)(naphthalen-1-yl)methanone 7h (IC50 = 0.07 +/- 0.02 mu M) showed equivalent COX-2 inhibitory potency as that of positive control etoricoxib (IC50 = 0.07 +/- 0.01 mu M) and an enhanced selectivity index of 115.14. Compound 7h exhibited 5-LOX IC50 of 0.29 +/- 0.09 mu M and reference drug zileuton showed IC50 of 0.15 +/- 0.05 mu M. In vivo studies of 7h including carrageenan-induced paw edema assay (63% inhibition of paw edema), antiulcer studies, biochemical assays, qRT-PCR analysis, and anticancer studies indicated that the present study has identified a good lead compound for the development of a potential anti-inflammatory drug having improved gastric safety profile.

Synthesis and Some Reactions of 2-(Thien-2-yl)naphtho[1,2-d]thiazole

Condensation of 1-aminonaphthalene with thiophene-2-carbonyl chloride in 2-propanol furnished N-(1-naphthyl)thiophene-2-carboxamide, the treatment of which with an excess of P2S5 in anhydrous pyridine led to the corresponding thioamide. Oxidation of the latter with potassium ferricyanide in an alkaline medium according to the Jacobson method yielded 2-(thien-2-yl)naphtho[1,2-d]thiazole. The latter was introduced into the electrophilic substitution reactions: nitration, bromination, formylation, and acylation. The reactions occur exclusively at the position 5 of the thiophene ring.

Synthesis, characterization, molecular docking and in vitro screening of new metal complexes with coumarin Schiff base as anticholine esterase and antipancreatic cholesterol esterase agents

In this work, Combining coumarin and thiazole with 3-tertiary butyl salicylaldehyde into in a single molecule, new Schiff base (CTS), and its metal complexes with palladium and platinum were synthesized and characterized by using well-known spectroscopic techniques such as H-1-NMR, C-13-NMR, FT-IR and LC-MS. And also, the formation of these complexes were confirmed by magnetic moment and conductivity measurements. The photophysical properties of CTS were studied and it was observed that the Schiff base has a sensitivity to CN-, F-, and AcO- anions. The quantum chemical calculations based on density functional theory (DFT) were done for explaining some experimental, structural, and spectroscopic data of the dyes. Also, to evaluate the binding interactions between the ligand (CTS) and its metal complexes and enzymes, molecular docking studies were performed and all the compounds tested to determine its inhibition potential against the cholinesterase (AChE and BChE) and pancreatic cholesterol esterase (CEase) enzymes. Both in vitro and in silico the results showed that all of the compounds could act as potent inhibitors of AChE, BChE, and CEase. The Pt (II) complex showed the most potent inhibitory property against all of the enzymes with IC50 values of 12 mu M for AChE, 23 mu M for BChE, and 21 mu M for CEase.
