Purpose: To evaluate the therapeutic potential of new bi-heterocycles containing a 1,3-thiazole and 1,3,4-oxadiazole in the skeleton against Alzheimer’s disease and diabetes, supported by in-silico study. Methods: The synthesis was initiated by the reaction of 4-methyl-1,3-thiazol-2-amine (1) with bromoacetyl bromide (2) in aqueous basic medium to obtain an electrophile,2-bromo-N-(4-methyl-1,3-thiazol-2-yl)acetamide (3). In parallel reactions, a series of carboxylic acids, 4a-r, were converted through a sequence of three steps, into respective 1,3,4-oxadiazole heterocyclic cores, 7a-r, to utilize as nucleophiles. Finally, the designed molecules, 8a-r, were synthesized by coupling 7a-r individually with 3 in an aprotic polar solvent. The structures of these bi-heterocycles were elucidated by infrared (IR), electron ionization-mass spectrometry (EI-MS), proton nuclear magnetic resonance (1H-NMR) and carbon nuclear magnetic resonance (13C-NMR). To evaluate their enzyme inhibitory potential, 8a-r were screened against acetylcholinesterase (AChE), but brine shrimp lethality bioassay. Results: The most active compound against AChE was 8l with half-maximal inhibitory concentration (IC50) of 17.25 ¡À 0.07 muM. Against BChE, the highest inhibitory effect was shown by 8k (56.23 ¡À 0.09 muM). Compound 8f (161.26 ¡À 0.23muM) was recognized as a fairly good inhibitor of urease. In view of its inhibition of alpha-glucosidase, 8o (57.35 ¡À 0.17muM) was considered a potential therapeutic agent. Conclusion: The results indicate that some of the synthesized products with low toxicity exhibit notable enzyme inhibitory activity against selected enzymes compared with the reference drug, and therefore, are of potential therapeutic interest.

Elicitors provide a broad spectrum of systemic acquired resistance by altering the physical and physiological status of the host plants and, therefore, are among the most successful directions in modern pesticide development for plant protection. To develop a novel elicitor with highly systemic acquired resistance, two series of thiazole- and oxadiazole-containing thiadiazole derivatives were rationally designed and synthesized according to the principle of combination of bioactive substructures in this work. Their structures were characterized by 1H nuclear magnetic resonance (NMR), infrared (IR), high-resolution mass spectrometry (HRMS), or elemental analysis. Their potential systemic acquired resistance as an elicitor was also evaluated; bioassay results indicated that, among the 23 compounds synthesized, three compounds, 10a, 10d, and 12b, displayed better systemic acquired resistance than the positive control, tiadinil, a commercialized 1,2,3-thiadiazolebased elicitor. In addition, three other compounds, 10f, 12c, and 12j, exhibited a certain degree of fungus growth inhibition In vitro or In vivo. Our results demonstrated that, in combination of bioactive substructures is an interesting exploration for novel pesticide development, thiazole-and oxadiazole-containing thiadiazole derivatives are potential elicitors with good systemic acquired resistance.

2-Oxazolidinones are saturated heterocyclic compounds, which are highly attractive targets in modern drug design. Herein, we describe a new, single-step approach to 3,4-disubstituted 2-oxazolidinones by aza-Michael addition using CO2 as a carbonyl source and 1,1,3,3-tetramethylguanidine (TMG) as a catalyst. The modular reaction, which occurs between a gamma-brominated Michael acceptor, CO2 and an arylamine, aliphatic amine or phenylhydrazine, is performed under mild conditions. The regiospecific reaction displays good yields (av. 75 %) and excellent functional-group compatibility. In addition, late-stage functionalization of drug and drug-like molecules is demonstrated. The experimental results suggest a mechanism consisting of several elementary steps: TMG-assisted carboxylation of aniline; generation of an O-alkyl carbamate; and the final ring-forming step through an intramolecular aza-Michael addition.

When Au(I) is provided with endocyclic soft thioether or endocyclic hard amine, endocyclic borderline imine and exocyclic hard amine coordination sites, the softer borderline endocyclic imine coordination site is favored. This is demonstrated by the synthesis and structural characterization (IR, MS, 1H, 13C and 31P NMR experiments and single-crystal X-ray diffraction analysis) of 2-aminoazole (2-amino-4-methylthiazole, 2-aminobenzothiazole and 2-aminobenzimidazole) complexes of [AuPPh3]+ (1-3). An unusual ring opening is observed for the reaction of 2-aminothiazoline with [Au(NO3)PPh3] yielding mu2-(2-mercapto-ethyl-cyanamide-kappa,S)bis(triphenylphosphine)gold(I) nitrate (4). Reactions of 2-aminoazoles with Au(C6F5)THT (THT = tetrahydrothiophene) yield [Au(C6F5)2]- stabilized by various cations. The formation of Au(2-aminothiazoline)C6F5 is again the exception.

1603-91-4. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 1603-91-4, Name is 4-Methylthiazol-2-amine. In a document type is Article, introducing its new discovery.

Novel Schiff base ligand based on the condensation of 4,6-diacetyl resorcinol with 2-amino-4-methylthiazole in addition to its metal complexes with Cr (III), Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II) and Cd (II) ions have been synthesized. The structure, electronic properties, and thermal behaviour of Schiff base and its metal complexes have been studied by elemental analysis, mass, 1H NMR, IR spectra, thermal analysis, and theoretically by density function theory. The ligand acted as mononegative bidentate (NO) ligand and all complexes showed octahedral geometry except Cu (II) showed tetrahedral geometry as indicated from the spectral and magnetic studies. The Cu (II), Zn (II) and Cd (II) complexes were non electrolytes while the rest of the complexes were electrolytes. The antibacterial plus anticancer activities of the parent Schiff base and its metal complexes were screened. In addition, the molecular docking study was performed to explore the possible ways for binding to Crystal Structure of Human Astrovirus capsid protein (5ibv) receptor.

This cross-coupling reaction proceeded smoothly and tolerated a broad range of functional groups (46 examples). A variety of functionalized N-alkylated (benzo)thiazoles were obtained in moderate to high yields. Notably, gram-scale synthesis of fanetizole (anti-inflammatory drug) was also realized through this protocol.
