CCK (26-30) is an N-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. The sulfated form of CCK (26-30) inhibits binding of [125I]CCK-33 to guinea pig cortical membranes by 10% when used at a concentration of 0.1 mM.
CCK (26-31) is an N-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. The sulfated form of CCK (26-31) inhibits binding of [125I]CCK-33 to guinea pig cortical membranes by 21% when used at a concentration of 0.1 mM.
Acetyl-Hirudin (54-65) (sulfated) directly binds to thrombin-rHCII(L444R) and hinders the interaction between the N-terminal acidic domain of rHCII and anion-binding exosite I of thrombin, which stabilizes the complex.
Hirudin (54-65; non-sulfated) is a desulfated peptide fragment of hirudin, an anticoagulant produced byH. medicinalis.1It inhibits fibrin clot formation induced by isolated bovine thrombin with an IC50value of 3.7 μM.2 1.Niehrs, C., Huttner, W.B., Carvallo, D., et al.Conversion of recombinant hirudin to the natural form by in vitro tyrosine sulfation.

CCK (27-33) is a C-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. Non-sulfated CCK (27-33) inhibits binding of [3H]naloxone in rat cerebellum membranes (IC50 = 4 uM) and inhibits electrically-stimulated contraction of isolated guinea pig ileum (IC50 = 17 uM), an effect that can be reversed by naloxone. Unlike sulfated CCK (27-33), the non-sulfated form does not reduce exploratory behavior in mice when administered at doses up to 1 uMol/kg.
Caerulein, desulfated TFA is Caerulein after desulfurization.Caerulein is a deceptide with the same five carboxy-terminating amino acids as gastrin and cholecystatin (CCK)..
AZ1366 is a potent tankyrase inhibitor that enhances irinotecan activity in tumors that exhibit elevated tankyrase and irinotecan resistance. Combination AZ1366 and irinotecan achieved greater anti-tumor effects compared to monotherapy. Activity was limited to CRC explants that displayed irinotecan resistance and increased protein levels of tankyrase and NuMA.
Indoxyl sulfate-d5 is intended for use as an internal standard for the quantification of indoxyl sulfate by GC- or LC-MS. Indoxyl sulfate is a uremic toxin and a metabolite of tryptophan. It is formed via sulfation of indole, an intermediate generated from tryptophan by intestinal bacteria, by the sulfotransferase (SULT) isoform 1A1 variant 2 (SULT1A1*2) in the liver. Indoxyl sulfate activates the aryl hydrocarbon receptor (AhR) in HepG2 40 6 hepatoma cells (EC50 = 12.1 nM in a reporter assay). It also inhibits the organic anion transporter (OAT) isoforms OAT1 and OAT3 (Kis = 34.2 and 74.4 µM, respectively for the rat transporters) in S2 proximal tubule cells. Indoxyl sulfate (0.2 and 1 mM) increases superoxide anion and nitric oxide levels in isolated human mononuclear blood cells. It increases serum creatinine and blood urea nitrogen (BUN) levels in the 5 6 nephrectomized rat model of chronic renal failure when administered at a dose of 50 mg kg.
