Discovery, biological evaluation and docking studies of novel N-acyl-2-aminothiazoles fused (+)-nootkatone from Citrus paradisi Macf. as potential alpha-glucosidase inhibitors

Nowadays, the discovery and development of a-glucosidase inhibitors from natural products or their derivatives represents an attractive approach. Here we reported studies on a series of novel N-acyl-2-aminothiazoles fused (+)-nootkatone and evaluation for their alpha-glucosidase inhibitory activities. Most of (+)-nootkatone derivatives exhibited more potent a-glucosidase inhibitory ability than the positive drug acarbose. In particular, compounds II7 and II14 showed the most promising alpha-glucosidase inhibitory ability with IC50 values of 13.2 and 13.8 mu M. II7 and II14 also exhibited relatively low cytotoxicities towards normal LO2 cells. Kinetic study indicated that compounds II7 and II14 inhibited the alpha-glucosidase in a noncompetitive manner, and molecular docking results were in line with the noncompetitive characteristics that II7 and II14 did not bind to the known active sites (Asp214, Glu276 and Asp349). Based on our findings, these (+)-nootkatone derivatives could be used as antidiabetic candidates.

Thiazole-based and thiazolidine-based protein tyrosine phosphatase 1B inhibitors as potential anti-diabetes agents

As a disease closely related to the metabolic syndrome, diabetes has become a public health issue that severely affects many people’s quality of life. The search for novel anti-diabetic agents remains the cornerstone to control this challenging disease. Protein tyrosine phosphatase 1B (PTP1B), a negative regulator of insulin and leptin signaling pathways, has turned out to be a potential target of type II diabetes mellitus (T2DM) and obesity. In recent years, the development of novel anti-diabetic drugs based on PTP1B inhibitors has captured the attention of many researchers. Thiazole, a five-membered heterocycle containing sulfur and nitrogen atoms, has been considered as an essential core skeleton for various active compounds. Furthermore, thiazolidines, representing a series of compounds with saturated thiazole rings, widely exist in natural products and synthetic compounds with a variety of pharmacological activities. Here, we focus on the emphasis of PTP1B in diabetes and the development of PTP1B inhibitors based on thiazole and thiazolidine derivatives in the past decade. Many PTP1B inhibitors and their chemical structures, selectivity, potency, and structure-activity relationship have been elaborated. The great majority of PTP1B inhibitors containing thiazole and thiazolidine moieties described in this review exhibit preferable activities, which would be of importance for the rational design and efficient application of PTP1B inhibitors with anti-diabetes activity.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 64359-81-5, you can contact me at any time and look forward to more communication. Product Details of 64359-81-5.

Ruthenium (II) Catalyzed C(sp(2))-H Bond Alkenylation of 2-Arylbenzo[d]oxazole and 2-Arylbenzo[d]thiazole with Unactivated Olefins

Functionalization of the bio-relevant heterocycles 2-arylbenzo[d]oxazole and 2-arylbenzo[d]thiazole has been achieved through Ru(II)-catalyzed alkenylation with unactivated olefins leading to selective formation of the mono-alkenylated products. This approach has a broad substrate scope with respect to the coupling partners, affords high yields, and works for gram scale synthesis using a readily available Ru-based catalyst. Mechanistic studies reveal a C-H activation pathway for the dehydrogenative coupling leading to the alkenylation. However, the results of the ESI-MS-guided deuterium kinetic isotope effect studies indicate that the C-H activation stage may not be the rate-determining step of the reaction. The use of a radical scavenging agent such as TEMPO did not show any detrimental effect on the reaction outcome, eliminating the possibility of the involvement of a free-radical pathway.

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.

Diradicalar Character and Ring Stability of Mesoionic Heterocyclic Oxazoles and Thiazoles by Ab Initio Mono and Multi-Reference Methods

Mesoionics are neutral compounds that cannot be represented by a fully covalent or purely ionic structure. Among the possible mesomeric structures of these compounds are the diradical electronic configurations. Theoretical and experimental studies indicate that some mesoionic rings are unstable, which may be related to a significant diradical character, that until then is not quantified. In this work, we investigated the diradical character of four heterocycles: 1,3-oxazol-5-one, 1,3-oxazol-5-thione, 1,3-thiazole-5-one, and 1,3-thiazole-5-thione. The oxazoles are known to be significatively less stable than thiazoles. DFT and ab initio single (B3LYP, MP2, CCSD, and QCISD) and ab initio multi-reference (MR-CISD) methods with three basis sets (6-311+G(d), aug-cc-pVDZ, and aug-cc-pVTZ) were employed to assess the diradical character of the investigated systems, in gas phase and DMSO solvent, from three criteria: (i) HOMO-LUMO energy gap, (ii) determination of energy difference between singlet and triplet wave functions, and (iii) quantification of the most significant diradical character (y(0), determined in the unrestricted formalism). All of the results showed that the diradical character of the investigated systems is very small. However, the calculated electronic structures made it possible to identify the possible origin of the oxazoles instability, which can help the design of mesoionic systems with the desired properties.

3-Aryl-2-(thiazol-2-yl)acrylonitriles assembled with aryl/hetaryl rings: Design of the optical properties and application prospects

New fluorescent thiazoles were designed and synthesized based on a 3-aryl-2-(thiazol-2-yl)acrylonitrile core. Three synthetic approaches were developed to introduce specific combinations of substituents at the 2-, 4- and 5-thiazole positions. The obtained thiazolyl-2-acrylonitriles exhibited a wide range of fluorescent colours (from green to red), long wavelength maxima and intensity depending on the combination of the substituents located at rings A, B and C. The expanded photophysical investigation established the best substituent combinations to increase their emission. Absorption and emission were studied in solvents with different polarities, as well as in DMSO-water and dioxane-water mixtures. The thiazoles showed multifunctional properties and exhibited good emission in the solid phase and in suspension (aggregation induced enhancement emission/AIEE effect). Photophysical investigations revealed a large Stokes shift, significant positive solvatochmmism, and the tunability of the colour and intensity. Sharp strengthening of the emission intensity of the thiazoles was observed upon stimulation with some acid (H2SO4 and BF3 center dot OEt2) in solvents and in the solid phase (HCl). State-of-the-art quantum mechanical calculations were performed to interpret the experimental findings. Biological experiments revealed the good penetration of the thiazoles into living cells and the accumulation both in lysosomes and, to a lesser extent, near membranes.

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.

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.
