New series of hydrazones 5-18 were synthesized, in good yields, by reacting 4-methyl-2-(4-(trifluoromethyl)phenyl)thiazole-5-carbohydrazide with differently substituted benzaldehyde. The resulting compounds were characterized via elemental analysis, physico-chemical and spectral data. An antimicrobial screening was done, using Gram (+), Gram (-) bacteria and one fungal strain. Tested molecules ...

An alternative approach toward the simple and robust synthesis of highly substituted peptidic thiazole derivatives using Ugi-multicomponent reaction (U-MCR) is described. Thus, we introduced the enantiopure (R)-2-methyl-2-isocyano-3-(tritylthio)propanoate as a novel class of isocyanide in MCR. This bifunctional isocyanide was found to undergo mild cyclodehydration to afford thiazole containing ...

4-Hydroxy-2-methyl-N-(2-thiazole)-2H-1,2-benzothiazine-3-carboxamide-1,1-dioxide (EX15) as nonsteroidal antiinflammatory drug (NSAIDs) of oxicam family has been synthesized bearing high selectivity for cyclooxygenase-2 (COX-2) inhibition and high ability to chelate with Cu(II) ions. The EX15Cu(II) complex, and [Cu(EX15)(OAc)(H2O)2], were synthesized and characterized by using elemental analysis...

The biosynthesis of thiamine appears to be accomplished with the initial formation of the pyrimidine and thiazole moieties by independent biosynthetic pathways, followed by a final step in which 2-methyl-4-amino-5-hydroxymethylpyrimidine and 4methyl-5-(/3-hydroxyethyl) thiazole are joined together to give thiamine. This conclusion was indicated originally from the observations that certain thia...

Thiazoles and thiazolyl-pyrazole derivatives have been efficiently synthesized under neat reaction conditions in excellent yields. Condensation of 3-(2-bromoacetyl)-4-hydroxy-6-methyl-2H-pyran-2-one (1), thiosemicarbazide (2) and various carbonyl compounds (3 & 5) gave corresponding thiazole (4) and thiazolylpyrazole derivatives (6) in excellent yields by using Hantzsch-Thiazole synthesis. The ...

Waste tires from traffic are a well-known environmental problem today. For this reason, the toxicity and potential biodegradation of crushed were tested in respiration test with microorganisms. A non-specific soil microbial community was used. Two experimental designs their effect on results compared—a eluate contact test, i.e., solution containing tire particles during test. The consumption di...

We present the synthesis and characterization of well-defined polycationic copolymers containing thiazole dyes in the side chain. Atom transfer radical polymerization (ATRP) was used for the copolymerization of 3-azidopropyl methacrylate (AzPMA) and N,N-dimethylaminoethyl methacrylate (DMAEMA) of different composition. Thiazole-based alkyne-functionalized dyes (e.g., 5-methyl-4-(prop-2-yn-1-ylo...

TiNi shape memory alloy (SMA) prepared by laser solid forming (LSF) has wide application prospect and research value. In this work, LSF-Ti49.2Ni50.8 was tested X-ray diffraction (XRD), differential scanning calorimetry (DSC), transmission electron microscopy (TEM). The microscopic characterization results show that there is a small amount of martensitic slat in besides the substrate. Lenticular...
