Summary: Enzyme inhibition is an active area of research in drug design and development. Chalcone derivatives have potential as new drugs with broad enzyme inhibitory activity. In this study, halogenated chalcones were synthesized and evaluated for their inhibitory activity against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and human erythrocyte carbonic anhydrase I (hCA I) and II (hCA II). The results showed potent inhibition against AChE and BChE, indicating their potential in the development of new drugs to treat global disorders such as Alzheimer's disease, glaucoma, and diabetes.

Summary: This study found that exposure to BPA exacerbates hypertension-induced pathological changes, including renal fibrosis, oxidative stress, elevated angiotensin-converting enzyme activity, dysfunction of antioxidant and tricarboxylic acid cycle enzymes, tissue lipid abnormalities, and expression of inflammatory factors. In addition, high levels of BPA have dose-dependent effects on kidney cells, including oxidative stress, mitochondrial dysfunction, and lipid peroxidation. Therefore, a precise investigation of BPA exposure in hypertensive populations is highly recommended during risk assessment.
