SIRT1
SIRT1 is a NAD\\+-dependent deacetylase that functions as a central regulator of cellular metabolism, stress responses, genomic stability, and aging through deacetylation of histones and multiple transcriptional regulators[1][2]. Mechanistically, SIRT1 integrates nutrient and energy signals with transcriptional programs that control mitochondrial biogenesis, fatty acid oxidation, glucose metabolism, autophagy, and cellular adaptation to metabolic stress[1][3]. Through coordinated interactions with metabolic signaling networks, SIRT1 contributes to maintenance of metabolic health across liver, skeletal muscle, adipose tissue, heart, and other organs[1]. In disease-related contexts, altered SIRT1 activity has been associated with aging, chronic inflammatory conditions, obesity, metabolic dysfunction, cardiovascular disorders, neurodegenerative diseases, and cancer-related processes, making it a widely used experimental target in translational research[2][4][5]. Compared with related sirtuin isoforms, SIRT1 is the most extensively characterized mammalian sirtuin and primarily mediates transcriptional regulation through deacetylation of nuclear histone and non-histone substrates, whereas other family members display distinct cellular localization and substrate preferences[1][2][4]. For experimental applications, SIRT1 activity can be modulated by small-molecule activators and inhibitors, and naturally occurring polyphenols such as resveratrol have been reported to activate SIRT1 in multiple model systems, providing useful tools for mechanistic studies of metabolism, inflammation, oxidative stress, and aging biology[3][4].

Acanthoic acid
0 ImagesCat. No.: HY-116136CAS No.: 119290-87-8Synonyms: NP1302Acanthoic acid (NP1302) is an orally active pimarane-type diterpenoid. Acanthoic acid is isolated from the root bark of Araliaceae family plant Eleutherococcus senticosus (Siberian ginseng). Acanthoic acid activates LXR and FXR. Acanthoic acid activates the AMPK-LKB1, SIRT1, and p38 MAPK signaling pathways and increases the phosphorylation level of ACC. Acanthoic acid downregulates the expression of SREBP-1, CYP2E1, HIF-1α, and PPARγ, and upregulates the expression of PPARα. Acanthoic acid induces Apoptosis by activating Caspase-3, promoting PARP cleavage, and downregulating Bcl-xL. Acanthoic acid exhibits antioxidant, anti-fibrotic, and hepatoprotective effects. It reduces lipid accumulation and lipogenesis. Acanthoic acid is used in studies on non-alcoholic fatty liver disease, alcoholic liver disease, acute promyelocytic leukemia, and Acetaminophen-induced hepatotoxicity.
