We herein disclose the microwave-assisted synthesis of previously unreported 6-methoxy-5,6-dihydro-5-azapurines, whose purine-like scaffold is promising for drug discovery. The method is simple, fast, and relies on easily accessible reagents such as trimethyl orthoformate, acetic acid, and aminotriazole-derived ,'-disubstituted formamidines. The preliminary biological evaluation revealed that selected representatives of synthesized 6-methoxy-5,6-dihydro-5-azapurines dose-dependently reduce the viability of HepG2 and A549 cancer cells having little to no influence on five tested purinergic receptors.

The fabrication of dual-quantum dot heterostructures offers a promising strategy to enhance the environmental remediation performance of photocatalysts. Herein, a BiWO-based Z-scheme heterojunction was constructed by incorporating carbonized polymer dots (CPDs) and CdS quantum dots (QDs) via a microwave-assisted solvothermal method. The 1 wt% CPDs/CdS QDs/BiWO (CCBW-1) composite achieved optimal Cr(VI) removal, reaching 97.

General procedures for the rhodium-catalyzed annulation of aryl/heteroaryl -pivaloyl hydroxamic acids and norbornadiene have been developed. Employing norbornadiene as an acetylene equivalent enables utilization of diverse heterocyclic substrates for this transformation which fail to react or undergo competitive Lossen rearrangement under previously reported conditions. Microwave heating significantly reduces reaction times compared to conventional protocols and allows a one-step process to be realized.

Unlabelled: The persistent challenge posed by antibiotic-resistant bacteria and tuberculosis necessitates innovative approaches to antimicrobial treatment. This study explores the synthesis and characterization of NiZrO₃ nanoparticles integrated with graphene nanoplatelets (GNP) and multi-walled carbon nanotubes (MWCNT), using a microwave-assisted green synthesis route, employing fenugreek () seed extract as a gelling agent. The synthesised nanocomposites were systematically analyzed using XRD, FT-IR, Raman spectroscopy, HR-SEM and HR TEM analysis to assess structural, optical, and morphological properties.

In this work, we have adopted an easy route to synthesizing bis-1,2,3-triazole-based benzophenone compounds via a 1,3-dipolar cycloaddition reaction (Click Chemistry). All the target compounds achieved better yields though the microwave-assisted method than the conventional method. Target compounds structure were confirmed based on the IR, 1H NMR, 13C NMR and HR Mass analysis.
