Keeping in view various pharmacological attributes of indole and coumarin derivatives, a new series indolindione-coumarin molecular hybrids was rationally designed synthesized. All synthesized hybrid molecules were evaluated for their antimicrobial potential against Gram-negative bacterial strains (Escherichia coli Salmonella enterica), Gram-positive (Staphylococcus aureus Mycobacterium smegmatis), four fungal (Candida albicans, Alternaria mali, Penicillium sp., Fusarium oxysporum) by using...

Keeping in view various pharmacological attributes of curcumin, coumarin, and isatin derivatives, triazole-tethered monocarbonyl curcumin-coumarin curcumin-isatin molecular hybrids have been synthesized evaluated for their antibacterial potential against Gram-positive (Enterococcus faecalis Staphylococcus aureus) Gram-negative (Pseudomonas aeruginosa Escherichia coli) human pathogenic bacterial strains. Among all hybrid molecules, A-4 B-38 showed the most potent activity with inhibition...

A novel series of triazole-linked isatin-indole-3-carboxaldehyde hybrids based on the febuxostat skeleton and its binding site interactions were rationally designed synthesized as potential xanthine oxidase inhibitors. Among hybrids, A19 showed most potent inhibition (IC50 = 0.37 µM) with mixed-type inhibitory scenario. Structure-activity relationship studies revealed that methoxy (OCH3 ) substitution position 5 isatin nucleus a two-carbon distance between triazole moiety is tolerable for...

Breast cancer is the most common among women. Currently, it poses a significant threat to healthcare system due emerging resistance and toxicity of available drug candidates in clinical practice, thus generating an urgent need for development new potent safer anti-breast candidates. Coumarin (chromone-2-one) elite ring widely distributed natural products possesses broad range pharmacological properties. The unique distribution efficacy coumarins attract product hunters, resulting...

Keeping in view the emerging need for potent and safer anti-breast cancer agents as well pharmacological attributes of isatin, quinolone, morpholine derivatives, novel hydrazine-linked morpholinated isatin-quinoline hybrids were designed, synthesized, evaluated agents. The synthesized hybrid compounds preliminarily screened against two breast cell lines (MCF-7 MDA-MB-231). Almost all synthetics showed inhibitory potential hormone-positive MCF-7 cells while being inactive hormone-negative...

Nanoformulation-based combinational drug delivery systems are well known to overcome resistance in cancer management. Among them, nanoemulsions well-known and thermodynamically stable suitable for carrying hydrophobic drugs phytoconstituents tackle drug-resistant cancers. In the present study, we have investigated effect of paclitaxel combination with erucin (natural isothiocyanate isolated from seeds Eruca sativa) loaded frankincense oil-based nanoemulsion formulation. The choice oil...
