Synonyms: DHEA sulfate-d6 sodium dihydrate; Prasterone sulfate-d6 sodium dihydrate
Dehydroepiandrosterone sulfate sodium dihydrate-d6 sodium dihydrate is the deuterium labeled Dehydroepiandrosterone sulfate sodium dihydrate. Dehydroepiandrosterone sulfate (DHEA sulfate; Prasterone sulfate) sodium dihydrate is a neurosteroid and the main secretion product of the adrenal gland. Dehydroepiandrosterone sulfate sodium dihydrate has both non-competitive antagonist activity of GABAA receptor and agonist activity of σ1 receptor. Dehydroepiandrosterone sulfate sodium dihydrate can partially penetrate the blood-brain barrier, inhibit GABAA receptor-mediated chloride influx, enhance NMDA receptor activity through σ1 receptors, exert anti-inflammatory, anti-glucocorticoid and antidepressant effects, and increase convulsive sensitivity. Dehydroepiandrosterone sulfate sodium dihydrate participates in neuroprotection, neurite growth regulation and catecholamine secretion regulation, and can be used in the study of depression, post-traumatic stress disorder (PTSD), Alzheimer's disease, etc. Dehydroepiandrosterone sulfate sodium dihydrate may also be a biomarker for cardiovascular disease mortality, and its concentration is independently and negatively correlated with mortality .

SKF 104976 is a 3,2-carboxylic acid derivative with potent 14-alpha-demethylase (14 alpha DM) inhibitory activity. SKF 104976 inhibited 14 alpha DM activity by 50% at 2 nM in Hep G2 cell extracts. SKF 104976 inhibited the incorporation of [14C]acetate into cholesterol in intact cells at similar concentrations, accompanied by accumulation of lanosterol, and resulted in a 40-70% decrease in 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) activity. SKF 104976 did not affect the uptake and degradation of low-density lipoprotein in Hep G2 cells, indicating that HMGR and low-density lipoprotein receptor activities are not coordinately regulated under these conditions. The inhibitory effect of SKF 104976 on HMGR activity remained unchanged even when the flux of carbon units in the sterol synthesis pathway was reduced by 80%. SKF 104976 did not inhibit HMGR activity under conditions where sterol synthesis was almost completely blocked by lovastatin .

SL-017 is a novel photoacoustic sensitizer and a derivative of photofrin B. It can be taken up by cells to the maximum extent within 30 minutes and is mainly localized in mitochondria. After being activated by visible light or ultrasound, SL-017 can significantly increase the production of reactive oxygen species (ROS). Low concentrations of SL-017 can rapidly cause the loss of mitochondrial membrane potential. SL-017 can also cause mitochondrial fragmentation, a process that occurs after the loss of membrane potential. Epoxyeicosatrienoic acids (EETs) can alleviate the loss of mitochondrial membrane potential caused by SL-017, but the antioxidant ascorbic acid has no such effect. These characteristics indicate that SL-017 mainly targets mitochondria and exerts its cytotoxic effect by triggering the collapse of mitochondrial membrane potential, generating ROS, and causing mitochondrial fragmentation. As a novel photoacoustic sensitizer, SL-017 has potential application value in photodynamic therapy and sonodynamic therapy.

CAS No.: 26647-82-5
Succinyl phosphonate is a α-Ketoglutarate Dehydrogenase Complex (KGDHC) modulator with neuroprotective activity. Succinyl phosphonate protects this complex, reduces cellular succinyl-CoA concentration, downregulates protein succinylation levels, and inhibits the activity of the α-ketoglutarate dehydrogenase complex. Succinyl phosphonate corrects hypoxic or ethanol-induced behavioral impairments, modulates exploratory behavior and emotional stress responses, and improves hypoxia tolerance. Succinyl phosphonate reduces glutamate excitotoxicity, restores the activity of the α-ketoglutarate dehydrogenase complex, reverses the changes in glutamate dehydrogenase and glutamine synthetase activities induced by β-amyloid (Amyloid-β), modulates cognitive function, and prevents β-amyloid-induced neuronal damage. Succinyl phosphonate improves microglial senescence, alleviates neuroinflammation, reactive oxygen species (ROS) production, lipid peroxidation, and the expression of proinflammatory cytokines. Succinyl phosphonate can be used in the research of Alzheimer's disease, aging-related neuroinflammation, and Parkinson's disease .

Chlorpromazine (Standard) is the analytical standard of Chlorpromazine (HY-12708). This product is intended for research and analytical applications. Chlorpromazine is an orally active, blood-brain barrier-transparent antipsychotic agent that effectively antagonises D2 dopamine receptors and 5-HT2A, which is widely used in schizophrenia and other psychiatric disorders. Chlorpromazine exerts anti-cancer activity through a variety of pathways, including anti-proliferation, induction of autophagy and cycle arrest (G2-M phase), inhibition of cytochrome c oxidase (CcO), inhibition of tumour growth and metastasis, and inhibition of tumour immune escape. Chlorpromazine also blocks hNav1.7 channels (IC50=25.9 μM; concentration-dependent) and HERG potassium channels (IC50=21.6 μM), which has potential for analgesic and cardiac arrhythmic studies. Chlorpromazine also can inhibit clathrin-mediated endocytosis .

ZXX2-77 is a cyclooxygenase-1 (COX-1) selective inhibitor belonging to the benzenesulfonylanilide class of compounds. It is reported as a novel analgesic that does not cause gastric damage. ZXX2-77 has a weak analgesic effect but exhibits potent COX-1 inhibitory activity in vitro. The low oral absorption rate of ZXX2-77 leads to its weak analgesic effect in vivo. At a dose of 30 mg/kg, the maximum plasma concentration of ZXX2-77 (1.2 mM) did not reach its COX-1 IC50 value (3.2 mM). In contrast, its derivative ZXX2-79, although weaker in vitro COX inhibitory activity, is better absorbed, exhibits stronger analgesic effect and hardly causes gastric damage. These findings suggest that ZXX2-77 and its derivatives as COX-1 selective inhibitors may become effective analgesics that do not cause gastric damage.

IRE1 Apoptosis FGFR

Research Areas:  

Inflammation/Immunology

PAIR2 is a highly selective inhibitor targeting the kinase domain of human IRE1α, with a Ki value of 8.8 nM against human IRE1α. PAIR2 fully occupies the ATP-binding site of the IRE1α kinase domain, partially antagonizes the ribonuclease activity of IRE1α, specifically inhibits regulated IRE1α-dependent decay (RIDD) and its mediated substrate cleavage, while preserving the splicing function of Xbp1 mRNA. PAIR2 also promotes the differentiation of B cells into plasma cells, blocks IRE1α-induced cell apoptosis, and restores the expression of Fgfr2 mRNA in AT2 cells. PAIR2 effectively reaches a steady-state concentration in the lung tissues of Mus musculus, and serves as an important tool for investigating the function of the IRE1α signaling pathway in diseases such as pulmonary fibrosis .

I-A09 and its derivatives, specifically 1,2,3-triazole-adamantylacetamide hybrids (5a–u), exhibit significant antitubercular activity. These hybrids were synthesized using copper-catalyzed click chemistry, combining bioactive fragments from antitubercular I-A09 and substituted adamantyl urea. The compound N-(1-adamantyl)-2-azido acetamide was reacted with various alkyl/aryl acetylenes to produce new analogues. Among them, N-(1-adamantan-1-yl)-2-(4-(phenanthren-2-yl)-1H-1,2,3-triazol-1-yl)acetamide (5t) showed the most promise with a minimum inhibitory concentration (MIC) of 3.12 μg/mL against Mycobacterium tuberculosis H37Rv, and a selectivity index greater than 15 .

TCM-4COOH is an AIE-active fluorescent probe for calcium ions. TCM-4COOH relies on aggregation-induced emission activity, and its carboxyl chelating group can bind to Ca 2+ and Mg 2+ to form insoluble aggregates, triggering fluorescence enhancement via restricting intramolecular motion (Ex/Em = 477/603 nm). TCM-4COOH shows pH independence in physiological environments (pH 4-9), can be strongly activated at Ca 2+ concentrations ranging from low nM to mM, and has a stronger binding ability to Ca 2+ than to Mg 2+. TCM-4COOH, as its acetoxymethyl ester derivative TCM-AM, can penetrate cell membranes for intracellular detection.
