Eco-friendly Cu/NiO nanoparticle synthesis: Catalytic potential in isatin-based chalcone synthesis for anticancer activity.

Isatin (1H-indole-2,3‑dione) is a natural heterocyclic compound extracted from various plants and has biological activity as an anticancer agent. Chalcones with the addition of several functional groups (hydroxyl, carboxyl, phenyl, etc.) may become useful templates for the development of new anticancer agents.

Preparation of azachalcone derivatives l-proline/ EtN-catalyzed aldol condensation and study of their antioxidant potential.

Chalcones, with two connected aromatic rings through an α,β-unsaturated carbonyl skeleton, display diverse biological roles like antimalarial, antibacterial, anticancer, and antioxidant activities. This research focuses on crafting azachalcone derivatives from 2-acetylpyridine and aromatic aldehydes using l-proline/EtN as a catalyst. Refinements encompass catalyst dosage, solvents, temperature, and post-reaction treatments.

Synthesis of camphor thiazole derivates from and its bioactivity as antioxidants and antidiabetes against alpha glucosidase enzymes.

Camphor is synthesized from the Sumatran camphor plant () in previous experiments. It can be synthesized with thiosemicarbazide, ethy-2‑chloro acetoacetate, and sodium acetate (catalyze) to form camphor derivate with thiazole ring structure. Hydrazine and phenylhydrazine were both used to make the thiazole ring variations.

A convenient method for the construction of triazole-bonded chalcone derivatives from acetophenone: Synthesis and free radical scavenging investigation.

The substituted 1,2,3-triazole core is prevalent in numerous commercially available drugs utilized for a wide range of clinical applications. Simultaneously, chalcone represents a privileged framework discovered in natural products exhibiting intriguing bioactivities. In this study, we synthesized triazole-bonded chalcone compounds (-), starting from a simple aromatic ketone, acetophenone, which underwent aldol condensation to give hydroxychalcone intermediate.

Synthesis of antioxidant and antimicrobial bioactive compounds based on the quinoline-hydrazone and benzimidazole structure.

Quinoline and its derivatives are known to have various biological activities such as antibacterial and antioxidant. Therefore, this study aims to synthesize quinoline moiety from isatin and ethyl acetoacetate by Pfitzinger reaction under acidic conditions. The benzimidazole derivative was synthesized from quinoline and o-phenylenediamine by a solvent-less reaction, while the hydrazone derivative was formed by the reaction with hydrazine hydrate and aromatic aldehyde.

Synthesis, α-Glucosidase Inhibitory Activity and Molecular Docking Study of Chalcone Derivatives Bearing a 1H-1,2,3-Triazole Unit.

Diabetes mellitus (DM) is a metabolic condition that is a major health concern around the world. The current study investigates the synthesis of a series of chalcone and 1H-1,2,3-triazole hybrid compounds and their in vitro inhibitory potential against α-glucosidase. The antidiabetic analysis revealed that compounds 4a and 4b are highly active agents with IC of 3.
