Article Synopsis
  • - Imported fire ants are major agricultural nuisances, and repellents can protect sensitive areas like hospitals from them.
  • - Research identified (-)-α-copaene from gurjun balsam as a key repellent agent, with a minimum effective dose of 15.6 μg/g against these fire ants.
  • - Modifying this compound through chemical processes led to the discovery of new derivatives with even greater repellency, achieving minimum effective doses as low as 3.9 μg/g.

Monoamine oxidases (MAOs) are a family of flavin adenine dinucleotide-dependent enzymes that catalyze the oxidative deamination of a wide range of endogenous and exogenous amines. Multiple neurological conditions, including Parkinson's disease (PD) and Alzheimer's disease (AD), are closely correlated with altered biogenic amine concentrations in the brain caused by MAO. Toxic byproducts of this oxidative breakdown, including hydrogen peroxide, reactive oxygen species, and ammonia, can cause oxidative damage and mitochondrial dysfunction in brain cells.

Dengue fever is a mosquito-borne viral disease that has become a serious health issue across the globe. It is caused by a virus of the Flaviviridae family, and it comprises five different serotypes (DENV-1 to DENV-5). As there is no specific medicine or effective vaccine for controlling dengue fever, there is an urgent need to develop potential inhibitors against it.

Pancreatic Lipase (PL) is a key enzyme responsible for the digestion of 50%-70% of dietary triglycerides, hence its inhibition is considered as a viable approach for the management of obesity. A series of indole-TZD hybrid analogues were synthesized, characterized and evaluated for their PL inhibitory activity. Knoevenagel condensation of various substituted indole-3-carboxaldehyde with substituted thiazolidinediones resulted in the formation of titled analogues.

Due to the pharmacological activities of quinazoline and quinazolinone scaffolds, it has aroused great interest in medicinal chemists for the development of new drugs or drug candidates. The pharmacological activities of quinazoline and its related scaffolds include anti-cancer, anti-microbial, anti-convulsant, and antihyperlipidaemia. Recently, molecular hybridization technology is used for the development of hybrid analogues with improved potency by combining two or more pharmacophores of bioactive scaffolds.

is an important indole alkaloid rich medicinal plant with diverse pharmacological activity. To understand the effect of extraction techniques, the stem bark sample of was subjected to continuous hot percolation, ultrasonic extraction, and cold maceration techniques. Continuous hot percolation technique extractive exhibited a potential pancreatic lipase (PL) inhibitory activity and further bio-assay guided fractionation resulted in the isolation of echitamine with a PL inhibitory activity (IC = 10.

A series of rhodanine-3-acetic acid derivatives were synthesized via Knoevenagel condensation of rhodanine-3-acetic acid with various substituted aromatic aldehydes. The synthesized derivatives were screened in vitro for understanding the inhibitory potential towards pancreatic lipase (PL), a key enzyme responsible for the digestion of dietary fats. Derivative 8f exhibited a potential inhibitory activity towards PL (IC = 5.

A series of twenty four 2-(carbazol-3-yl)-2-oxoacetamide analogues were synthesized, characterized and evaluated for their pancreatic lipase (PL) inhibitory activity. Porcine PL was used against 4-nitrophenyl butyrate (method A) and tributyrin (methods B and C) as substrates during the PL inhibition assay. Compounds 7e, 7f and 7p exhibited potential PL inhibitory activity (IC values of 6.
