Herein, we report the design, synthesis and biological evaluation of the anti-inflammatory activities of N-phenyl sulfonamide linked N-acylhydrazones (NPS-NAH), using the molecular hybridization approach. Hybrid compounds were further validated by theoretical studies. Compound 1f from series-1 and compound 2a from series-2 exhibited strong selective COX-2 enzyme inhibition at IC50 = 8.9 μM and 8.4 μM respectively. Effective in vivo anti-inflammatory profiling of potent and selective COX-2 inhibitors, including compound 1f and 2a was carried out and compared with known COX-2 inhibitors. Subsequently, these compounds were tested for antioxidant activity, and 1h (IC50 = 28.62 μM) from series-1 and compound 2d (IC50 = 25.34 μM) from series-2 were found to be potent anti-oxidants. Additionally, these compounds were screened for antibacterial activity, and compound 1l and 2b exhibited better Gram +ve and -ve anti-bacterial activity than the reference standards, Ciprofloxacin and Norfloxacin. These results validated the idea of exploiting the hybridization strategy for the identification of new N-phenyl sulfonamide-NAH derivatives for optimizing anti-inflammatory, antioxidant and anti-bacterial activities.

A site-selective direct arylation reaction of carbazole and other N-heterocycles with diazo-naphthalen-2(1H)-ones has been developed. While Au(i)-NHC catalysts lead to selective C3-arylation, palladium acetate allows for selective N-H arylation, displaying complete site-selectivity each. To show the applicability of these arylation reactions, one-pot, two-fold diarylation reactions of carbazole were demonstrated.

A new series of benzenesulphonamide linked-1,3,4-oxadiazole hybrids (6a–s) has been synthesized and tested for their carbonic anhydrase inhibition against human (h) carbonic anhydrase (CA) isoforms hCA I, II, IX, and XIII. Fluorescence properties of some of the synthesized molecules were studied. Most of the molecules exhibited significant inhibitory power, comparable or better than the standard drug acetazolamide (AAZ) on hCA XIII. Out of 19 tested molecules, compound 6e (75.8 nM) was 3 times more potent than AAZ (250.0 nM) against hCA I, whereas compound 6e (15.4 nM), 6g (16.2 nM), 6h (16.4 nM) and 6i (17.0 nM) were found to be more potent than AAZ (17.0 nM) against isoform hCA XIII. It is anticipated that these compounds could be taken as the potential leads for the development of selective hCA XIII isoform inhibitors with improved potency.
