Nicotinic Acid Derivatives As Novel Noncompetitive α-Amylase and α-Glucosidase Inhibitors for Type 2 Diabetes Treatment.

A library of novel nicotinic acid derivatives, focusing on the modification of position 6 of the pyridine ring with (thio)ether functionalities, was mostly produced through an innovative green synthetic approach (Cyrene-based) and evaluated for their α-amylase and α-glucosidase inhibitory activity. Compounds and demonstrated micromolar inhibition against α-amylase (IC of 20.5 and 58.

Elimination of damaged mitochondria during UVB-induced senescence is orchestrated by NIX-dependent mitophagy.

Skin aging is the result of two types of aging, "intrinsic aging" an inevitable consequence of physiologic and genetically determined changes and "extrinsic aging," which is dependent on external factors such as exposure to sunlight, smoking, and dietary habits. UVB causes skin injury through the generation of free radicals and other oxidative byproducts, also contributing to DNA damage. Appearance and accumulation of senescent cells in the skin are considered one of the hallmarks of aging in this tissue.

CLCA2: A Potential Guardian against Premature Senescence and Skin Aging.

Cellular senescence, a state of irreversible growth arrest, is implicated in various age-related pathologies, including skin aging. In this study, we investigated the role of CLCA2, a calcium-activated chloride channel accessory protein, in cellular senescence and its implications for skin aging. Utilizing UVB and Nutlin3a-induced senescence models, we observed the upregulation of CLCA2 at both transcriptomic and proteomic levels, suggesting its involvement in senescence pathways.

Bioequivalence of a New Pediatric Paracetamol Oral Suspension Compared With a Marketed Formulation in Healthy Adults: A Randomized, Open-Label Study.

Background: A new oral paracetamol formulation with the same paracetamol quantity (24 mg/mL) as a marketed formulation but with finer active ingredient particle size and lower amounts of maltitol (5.85 g/dose in the test formulation vs 7.25 g/dose in the reference formulation) and sorbitol (2.

Mitochondrial dysfunction and cisplatin sensitivity in gastric cancer: GDF15 as a master player.

Gastric cancer, a major global health concern, poses challenges in effective treatment, notably due to chemoresistance. This study investigates the role of growth/differentiation factor-15 (GDF-15) in mitochondrial dysfunction and its impact on cisplatin sensitivity in gastric cancer cells. In this issue of The FEBS Journal, Wang et al.
