The new series of asymmetrical pyrazole curcumin analogues 4a-g were synthesized by using polyethylene glycol (PEG-400) as a green reaction medium and evaluated for their in vivo analgesic and in vitro antioxidant (H2 O2 , DPPH, Ferrous reducing power and Nitric oxide scavenging activity) and anti-inflammatory activities. All the compounds synthesized 4a-g showed the potential to demonstrate analgesic activity as compared to the standard ibuprofen. Among the tested series, compounds 4e and 4b exhibited good hydrogen peroxide scavenging activity as compared to the standard butylated hydroxy toluene (BHT). Compounds 4b, 4d, 4f, and 4g showed good DPPH free radical scavenging activity. Compounds 4b, 4c, 4d, 4e and 4g showed excellent ferrous-reducing power activity, whereas all the compounds showed better nitric oxide scavenging activity than standard ascorbic acid. Additionally, all the synthesized compounds were also screened for their in vitro anti-inflammatory activity. Compounds 4b, 4d, 4f and 4g showed good anti-inflammatory activity as compared to standard diclofenac sodium.

By understanding the rampant infections of Mycobacterium tuberculosis (Mtb) and inflammations caused due to the generation of radical species during the Mtb infection, a series of (E)‐2‐(2‐allylidenehydrazinyl)thiazole derivatives, with dual‐action properties, was designed. The molecules were designed with a considerable variation in LogP, one of the critical parameters in physicochemical properties, and analyzed for their drug‐likeness. For the synthesis, a simple, green, and multicomponent one‐pot synthesis method was developed. The in vitro inhibition potentials were evaluated against Mtb H37Rv by the microplate Alamar Blue assay. The results reveal that compound 6 was potent, with a MIC value of 6.5 µg/ml, and showed better interactions with the KasA protein with binding free energy (ΔG) of −9.4 kcal/mol. Also, the radical scavenging properties were studied to establish the dual‐action properties of the molecules. Compound 9 exhibited promising antioxidant and nitric oxide radical scavenging activities, with 81.7% and 81.0%, respectively, at 1,000‐μg/ml concentration.

The efficient metal-free oxidative coupling of arylmethylamines with indoles has been developed using molecular oxygen as a green oxidant towards a novel rout of 3,3′-bis(indolyl)methanes (BIMs) synthesis.

Thiazole derivatives were prepared by one-pot procedure by the reaction ofα-haloketones, thiourea and substitutedo-hydroxybenzaldehyde under environmentally solvent free conditions.

An efficient and convenient approach for the synthesis of thiazole derivatives from α-halo ketones, thiosemicarbazide, and o-hydroxybenzaldehydes in poly(ethylene glycol) (PEG-400) is described. The preparation procedure presented is operationally simple and environmentally benign. Some of the major advantages of this procedure are high yields and ease of operation.
