Abstract:
A unique approach for the synthesis of new thiazole O-glycosides is presented in this work. 2-Amino-4-hydroxy-phenyl-1,3-thiazole-5-carboxaldehyde (3a) was reacted with phenyl glyoxal and benzil to form 4-(4-hydroxy-phenyl)-5-(4-phenyl-1H-imidazol-2-yl)-thiazol-2-amine (4a) and 4-(4-hydroxy-phenyl)-5-(4,5-diphenyl-1H-imidazol-2-yl)-thiazol-2-amine (4b), respectively. A series of substituted Schiff bases of 4a and 4b were synthesized reacting with various aryl aldehyde to form 2-(imino substituted benzal)-4-(4-hydroxy-phenyl)-5-(4-phenyl-1H-imidazol-2-yl)-thiazoles (5a-e) and 2-(imino substitut

The products of double carbonylation were obtained from bis(chloromethyl)tetrafluorobenzenes and benzal fluorides. For benzal chloride derivatives, the possibility of selective mono- or dicarbonylation was shown to depend on the amount of antimony pentafluoride. In the case of polyfluori

Abstract:
Abstract Copper alloys are utilized in industrial cooling systems because of their excellent heat transfer properties. However, a corrosion inhibitor is needed to prevent equipment failures and, very importantly, to reduce the discharge of toxic copper compounds into the environment. Azoles, such as benzotriazole (BZT) and tolyltriazole (TTA), have been used for this purpose but they do not protect copper in the presence of oxidizing halogens which are commonly added to cooling systems to control microbiological activity. The halogens react with BZT and TTA and destroy their corrosion inhibiti

Abstract:
This research aims to design anticancer molecules using the hybridization concept based on molecular derivatives of salicylic acid. The investigation explores structures with and without linked amino acid alanine through an in-silico docking approach. The research conducts screenings of the designed salicylic acid derivative molecules against receptors, including MMP9, MMP2, CDK2, P53, BAK EGFR, and ADP Ribose Polymerase. The most promising docking results for multitarget cancer compounds were observed in salicylic acid derivatives with amino acid linkages, specifically salicylic acid-curcumin

Abstract:
Laser induced fluorescence techniques can be used to obtain rotationally resolved electronic spectra of moderately large aromatic and organometallic radicals cooled to &lt;2 K in a supersonic free jet expansion. Aromatic organic radicals studied include cyclopentadienyl, benzyl, triphenyl methyl, and substituted derivatives thereof. Organometallic radicals studied include Cd and Zn monomethyl as well as group IIA and IIB derivatives of cyclopentadienyl, methylcyclopentadienyl, and pyrrolyl radicals.

Abstract:
This work synthesized various novel benzo[c]quinoline compounds, detailed their structural features, and examined their anticancer activity in vitro. First, the nitrogen atom in benzo[c]quinoline is quaternized, and the in situ-formed ylide is then subjected to a [3+2] dipolar cycloaddition reaction. A detailed investigation was conducted to determine how successful traditional thermal heating (TH) synthesis was in comparison to microwave (MW) and ultrasonic (US) irradiation. FTIR, HRMS, and NMR were the three spectral techniques that were used to prove the structure of all the obtained compou
