Benzimidazolone derivatives were discovered as novel CB2 selective agonists. Structure Activity Relationship (SAR) studies around them were examined to improve metabolic stability. Compound 39 exhibited excellent metabolic stability in human liver microsomes (HLM) and significant attenuation of the chronic colonic allodynia in the TNBS-treated rats by po administration.

While soundscapes shape the structure and function of auditory systems over evolutionary timescales, there is limited information regarding the adaptation of wild fish populations to their natural acoustic environments. This is particularly relevant for freshwater ecosystems, which are extremely diverse and face escalating pressures from human activities and associated noise pollution. The Siamese fighting fish is one of the most important cultured species in the global ornamental fish market and is increasingly recognized as a model organism for genetics and behavioural studies.

Herein, novel thiazolo[4,5-]quinoxalin-2-ones 2-6 and thiazolo[4,5-]quinoxalin-2(3)-imines 7-9 were synthesized and characterized using elemental analysis, IR spectroscopy, and H/C NMR to confirm their structures. The efficacy of the newly designed thiazolo-quinoxalines 2, 3, 4, 5, 7, 8, and 9 against the cotton leafworm (2nd and 4th instar larvae) was evaluated, and results revealed insecticidal activity with variable and good mortality percentages. A SAR study was also discussed.

The biological nitrogen removal process in wastewater treatment inevitably produces nitrous oxide (NO), a potent greenhouse gas. Coarse bubble mixing is widely employed in wastewater treatment processes to mix anoxic tanks; however, its impacts on NO emissions are rarely reported. This study investigates the effects of coarse bubble mixing on NO emissions in a pilot-scale mainstream nitrite shunt reactor over a 50-day steady-state period.

Natural products (NPs) play a crucial role in drug discovery, with over 30% of recent FDA-approved drugs derived from them. Plants from the genus Goniothalamus, belonging to the Annonaceae family, have garnered significant interest as potential sources of active lead compounds. Over the past five decades, researchers have isolated 357 compounds from Goniothalamus species (GCs), which exhibit a wide range of pharmacological properties, including cytotoxicity, antibacterial, antifungal, antiplasmodial, antioxidant, and other activities.

Skeletal muscle plays a significant role in both local and systemic energy metabolism. The current investigation aims to explore the role of the Bambi gene in skeletal muscle, focusing on its implications for muscle hypertrophy and systemic metabolism. We hypothesize that skeletal muscle-specific deletion of Bambi induces muscle hypertrophy, improves metabolic performance, and activates thermogenic adipocytes via the reprogramming of progenitor of iWAT, offering potential therapeutic strategies for metabolic syndromes.
