A series of fourteen (A1 - A14) qunioline based chalcones were screened for reverse transcriptase inhibitors (RT) and found potentially active against RT. Bioassay, theoretical and dockings studies with RT (the enzyme required for reverse transcription of viral RNA) results showed that the type and positions of the substituents seemed to be critical for their inhibition against RT. The bromo and chloro substituted chalcone displayed high degree of inhibition against RT. The A4 andA6 showed high interaction with RT, contributing high free binding energy (ΔG -9.30 and -9.13kcal) and RT inhibition value (IC50 0.10μg/ml and 0.11μg/ml).

This study presents a comprehensive exploration of the synthesis of novel compounds targeting Chagas Disease (CD) caused by Trypanosoma cruzi. It is a global health threat with over 6-7 million infections worldwide. Addressing challenges in current treatments, the investigation explores diverse compound classes, including thiazoles, thiazolidinone, imidazole, pyrazole, 1,6-diphenyl-1H-pyrazolo[3,4-b] pyridine, pyrrole, naphthoquinone, neolignan, benzeneacyl hydrazones, and chalcones-based compounds.

Given the ease of synthetic accessibility and the promising biological profile demonstrated by both imidazo[1,2-a]pyridine and Chalcone derivatives, a series of Chalcone-based imidazo[1,2-a]pyridine derivatives were synthesized and characterized using H NMR, C NMR, Mass Spectrometry and FTIR techniques. Density functional theory (DFT) was employed to investigate the structural and electronic properties, providing insights into potential reactive sites. The synthesized compounds were evaluated in vitro for their antiviral properties against human immunodeficiency virus type-1 (HIV-1) and human immunodeficiency virus type-2 (HIV-2) in MT-4 cells.

is an important medicinal plant, rich in flavonoid, with various pharmacological activities such as stomachic and antioxidant properties. In this study, we integrated metabolome and transcriptome analyses to reveal metabolite and gene expression profiles of both green (GDd) and purple-red (RDd) of semi-annual and annual stems. A total of 244 flavonoid metabolites, mainly flavones and flavonols, were identified and annotated.

Objective: Based on Toll Like Receptor 4 (TLR4)/Nuclear Factor-κB (NF-κB) Exploring the effects of Licochalcone A (LCA) on the proliferation, invasion, and drug resistance of glioma cells through signaling pathways.
Methods: Cultivate human glioma cell line U251 in vitro, induce drug-resistant cell line U251/TMZ with Temozolomide (TMZ), and validate the results. Different concentrations of licorice chalcone A were used to treat U251 cells and U251/TMZ cells, and were named as control group, low-dose group, medium-dose group, and high-dose group, respectively.

Chitosan is a bio-based material that is more environmentally friendly than traditional petroleum-based materials, but its biofilms often suffer from brittleness and limited antioxidant and antibacterial properties. To overcome these challenges, chemically modified chitosan is a key solution. Herein, a novel CS-LA/CHA films were prepared through a radical reaction of chitosan (CS), lipoic acid/chalcone derivative (LA/CHA) and N,N-methylene bisacrylamide (MBA).
