Synonyms: Dextran 3; Dextran D3; Dextran T3(MW 2400-3600)
Dextran T3 (Dextran 3; Dextran T3(MW 2400-3600)) is a neural tracer and intestinal permeability probe that can move anterogradely and retrogradely in neuronal axons by passive diffusion. Dextran T3 (MW 3,000) is able to permeate across the intestinal epithelial cell membrane in the presence of cholera toxin-induced cytoskeletal disturbance. Dextran T3 (MW 3,000) is used as a fluorescent marker to rapidly label developing neurons (such as Xenopus retinal ganglion cells) and to assess intestinal barrier function. It can be used to study axonal transport in neuroanatomy and permeability changes in intestinal pathophysiology. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .

Kumatakenin is an orally active apoptosis inducer and autophagy inhibitor, with a Kd value of 2.94 μM for mouse ATG5. Kumatakenin increases the activities of caspase-3, caspase-8 and caspase-9, thereby inducing caspase-dependent apoptosis in ovarian cancer cells. Kumatakenin reduces the expression of chemokines and pro-oncogenic factors in ovarian cancer cells, and inhibits M2 macrophage polarization. Kumatakenin inactivates TRIM65 function, reduces the expression and stability of FASN, and thus inhibits the proliferation, migration, invasion and tumor progression of esophageal cancer cells. Kumatakenin interacts with ATG5 to reduce its protein level, decrease LC3 level, and reduce the number of autophagosomes in the hippocampus. Kumatakenin binds to Eno3 to upregulate its expression, reduce the stability and expression level of IRP1 mRNA, inhibit ferroptosis, alleviate intestinal inflammation, and restore epithelial barrier function. Kumatakenin enhances the efficacy of antibiotics against pathogenic bacteria, inhibits SARS-CoV-2 replication, and reduces cytokine production. Kumatakenin is applicable to research related to ovarian cancer, esophageal cancer, depression and colitis .

Target:  

CRFR

Astressin 2B TFA is a blood-brain barrier-impermeable, highly selective CRFR2 antagonist (rCRFR2, IC50=0.57 nM). Astressin 2B TFA blocks the protective effects mediated by CRFR2, thereby exacerbating indomethacin (HY-14397)-induced hemorrhagic intestinal injury in rats. Astressin 2B TFA reverses the protective effects of Urocortin 1 against intestinal hypermotility, bacterial invasion and upregulation of inflammatory mediators. Astressin 2B TFA also blocks the anxiogenic effect of Urocortin 2 and attenuates stress-induced anxiety-related behaviors. In the Clostridioides difficile toxin A (C. difficile toxin A)-mediated enteritis model, Astressin 2B TFA mimics the phenotype of CRFR2-deficient mice, significantly exacerbating intestinal epithelial damage, edema, neutrophil migration and the expression of multiple proinflammatory cytokines. Astressin 2B TFA is an important tool molecule for investigating the intestinal protective mechanisms of CRFR2 .

CAS No.: 82375-29-9
Humantenine is a highly toxic indole alkaloid from Gelsemium elegans (Gardn. & Champ.) Benth. that binds to RNA m6A modification regulatory proteins (ALKBH5, METTL). Humantenine stably binds via hydrogen bonding and hydrophobic interactions and disrupts the m6A methylation level of target genes, thereby impairing the expression of intestinal epithelial cell tight junction and cytoskeleton-related genes, causing intestinal barrier dysfunction and significant intestinal cytotoxicity. The intraperitoneal injection LD50 values of Humantenine are <1 mg/kg in mice, 1.2 mg/kg in male rats and 1.5 mg/kg in female rats, respectively. Species differences exist in the metabolism of Humantenine in human, porcine, goat and rat liver microsomes, and demethylation, dehydrogenation and oxidation occur in liver microsomes .
