Tuning emissive color of trivalent terbium ion through environmental factors: optoelectronic insights from theoretical, spectral and computational studies.

The combination of 4,4,4-trifluoro-1-phenyl-1,3-butanedione (TFPB) and pyrazine (pyz) with Tb ions forms two distinct types of complexes, represented by the formulas [Tb(TFPB)(L)], where L is either HO or pyz, and [(Tb(TFPB))pyz]. A detailed examination of the impact of the surrounding environment on the photophysical properties of these synthesized complexes was conducted. Photoluminescence (PL) analysis indicated that the magnetic dipole transition (D → F) is dominant in Tb(iii)-based systems.

Multicomponent Synthesis of 2,4,5-Trisubstituted Thiazoles Using a Sustainable Carbonaceous Catalyst and Assessment of Its Herbicidal and Antibacterial Potential.

Herein, a novel, biocatalyzed, and on-water microwave-assisted multicomponent methodology have been developed for the synthesis of trisubstituted thiazoles (-). The reaction was catalyzed using a sulfonated peanut shell residue-derived carbonaceous catalyst (). The developed catalyst was characterized using Fourier transform infrared (FTIR), a Brunauer-Emmett-Teller (BET) surface area analyzer, a field emission scanning electron microscope (FE-SEM), energy-dispersive X-ray (EDX), and a particle size analyzer (PSA).

Environment benign synthesis of 5-acyl-4-hydroxypyridin-2(1)-one derivatives as antioxidant and -amylase inhibitors.

Aim: Oxidative stress, caused by postprandial activities, is a major global health issue causing chronic diseases like diabetes mellitus, cancer, and asthma. Therefore, it was envisaged to design and synthesize a series of substituted 4-hydroxypyridine-2(1 h)-ones in order to develop new molecules that can reduce oxidative stress and modulate α-amylase activity also.

Materials & Methods: An environmentally benign, solvent and catalyst free, natural product inspired synthesis of 4-hydroxypyridin-2(1 h)-one derivatives has been developed.

Diastereomeric pure pyrazolyl-indolyl dihydrofurans: Unveiling isomeric selectivity in antibacterial action via in vitro and in silico insights.

Developing pure diastereoisomeric molecular hybrids for the selective inhibition of bacterial growth opened new avenues for combating the ever-increasing microbial resistance. Considering this, a series of diastereoisomeric pure pyrazolyl-dihydrofurans (7a-7y) were synthesized and characterized using NMR, LCMS, and X-ray crystallography. DFT based method was used to explore the configurational stability of cis over trans isomeric form.

Naphthoquinone fused diazepines targeting hyperamylasemia: potential therapeutic agents for diabetes and cancer.

Elevated levels of amylase in the blood, known as hyperamylasemia, have been correlated with diabetes and cancer. To investigate the impact of hyperamylasemia on cellular proliferation, it is imperative to design dual inhibitors targeting both α-amylase activity and cancer progression. Naphthoquinone fused diazepines have been synthesized using multicomponent reaction with high Eco-score of 87 and evaluated for bio efficacy using antioxidant and α-amylase inhibition assay.
