2-Phenylpyridine
CAS :2-Phenylpyridine is a heterocyclic organic compound that has been shown to have x-ray crystal structures. It has redox potentials, nitrogen atoms, and a fatty acid group attached. 2-Phenylpyridine has been shown to have nmr spectra that are characteristic of a transfer reaction mechanism. The steric interactions and the biphenyl groups have been shown to have ancillary effects on the reaction mechanism. 2-Phenylpyridine is also known to coordinate in a geometric shape called octahedral, which is most likely due to hydrogen bonding and photophysical properties. The analytical chemistry of this molecule consists of determining its melting point, boiling point, and density. 2-phenylpyridineFormule :C11H9NDegré de pureté :Min. 95%Masse moléculaire :155.2 g/molAF-2
CAS :AF-2 is a potent, selective and competitive antagonist at the nicotinic acetylcholine receptor (nAChR). AF-2 binds to the extracellular domains of the nAChR and prevents agonists from binding. It has been shown to inhibit acetylcholine release in isolated heart preparations with high affinity and selectivity. The drug has been tested as an anthelmintic against Caenorhabditis elegans and found to be effective. AF-2 is a cholinergic compound that binds to ganglia, leading to a biphasic response. It also has significant effects on the central nervous system, inhibiting both nicotinic and muscarinic acetylcholine receptors. AF-2 is sequenced according to the following formula: H-Lys-His-Glu-Tyr-Leu-Arg-Phe NH2Formule :C47H70N14O10Degré de pureté :Min. 95%Masse moléculaire :991.15 g/molAngiotensin I-Converting Enzyme (ACE) Inactivator Cyanoac-Phe-Phe-OH
CAS :Cyanoac-Phe-Phe-OH is a hydrolytic enzyme that irreversibly inactivates the ACE enzyme. It acts as an inhibitor of angiotensin-converting enzyme and inhibits the conversion of angiotensin I to angiotensin II, which is involved in blood pressure regulation. Cyanoac-Phe-Phe-OH has been shown to be more potent than captopril, another ACE inhibitor. It also has a longer half life and greater selectivity for ACE over other serine proteases.Formule :C21H21N3O4Degré de pureté :Min. 95%Masse moléculaire :379.41 g/molSuc-Ala-Ala-Pro-Nva-pNA
CAS :Suc-Ala-Ala-Pro-Nva-pNA is a tetrapeptide. It is one of the most potent trypsin inhibitors that has been identified to date and it has been shown to inhibit pancreatic trypsin with a potency similar to that of the synthetic inhibitor benzamidine. Suc-Ala-Ala-Pro-Nva-pNA binds to the active site of trypsin, preventing proteolysis of peptides. This inhibition is reversible because it does not bind covalently to any other sites on the enzyme. Suc-Ala-Ala-Pro-Nva-pNA inhibits proteases by binding to their active site and blocking access by the substrate. The binding occurs through noncovalent hydrophobic interactions with amino acids in the active site, including valine, leucine, phenylalanine, and methionine.

CAS :H-D-Ala-Gln-OH is a modified structural analog of l-fucose that has been shown to be a potent immunostimulant in vitro. The hydrocarbon chain on this molecule is substituted with an H-D-Ala moiety, which provides the molecule with a hydroxyl group. This modification increases the solubility of the molecule, thereby making it more suitable for in vivo administration. Additionally, modifications to the hydrocarbon chain may have functional consequences on the molecule's activity (e.g., substitutions may increase or decrease its ability to induce interleukin).Formule :C8H15N3O4Degré de pureté :Min. 95%Masse moléculaire :217.22 g/molH-Thr-Leu-OH
CAS :L-threonine is an amino acid that can be found in proteins. It is a dipeptide of the essential amino acid l-threonine and the nonessential amino acid l-serine. L-Threonine can be metabolized to generate adenosylhomocysteine, which can serve as a substrate for S-adenosylmethionine synthetase. This enzyme converts S-adenosylmethionine to 5'-methylthioadenosine, which is then converted to HMTPA by methyltransferase. HMTPA is subsequently converted to homocysteine through the action of cystathionase or serine hydroxymethyltransferase. Homocysteine may then be converted back into methionin by methylenetetrahydrofolate reductase (MTHFR).Formule :C10H20N2O4Degré de pureté :Min. 95%Masse moléculaire :232.28 g/molpTH (1-44) (human)

CAS :Enkephalin is a peptide belonging to the group of opioid drugs. It is a neurotransmitter that binds to kappa-opioid receptors and μ-opioid receptors. Enkephalin has been shown to inhibit voltage-dependent calcium channels and mitochondrial membrane potential in neurons, which leads to neuronal death. This drug also inhibits the production of cyclic guanine monophosphate (cGMP) by inhibiting guanine nucleotide-binding proteins at the plasma membrane, leading to a decrease in the synthesis of proteins and DNA. The dextran sulfate test can be used to measure enkephalin activity by precipitating it from solution with sodium sulfate. Additionally, this drug can be used as a p-gp inhibitor for the treatment of cancer cells.Formule :C29H39N5O7Degré de pureté :Min. 95%Masse moléculaire :569.65 g/molMeOSuc-Ala-Ala-Pro-Ala-chloromethylketone
CAS :MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone is a peptidyl substrate for the enzyme carboxypeptidase A. This substrate has a high specificity for carboxypeptidase A and does not bind to other enzymes such as carboxypeptidase B, D, or L. The hydrophobic nature of this substrate has been shown in both hamsters and macaques. MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone also shows cardiovascular effects in both animal models.

CAS :Neurotensin (NT) is a peptide hormone that belongs to the family of amides and is found in the stomach, small intestine, and central nervous system. NT is an agonist of the neurotensin receptor and binds to allosteric binding sites on the receptor. Neurotensin (NT) is modified by proteolysis, which may be due to its acidic residue at position 9. This modification leads to increased affinity for the neurotensin receptor binding site. The pharmacokinetic properties of NT are not well-understood as it has been shown to have both high lipophilicity and low plasma protein binding rates. Neurotensin (NT) receptors have been shown to be G protein coupled receptors with different subtypes, such as NT1, NT2A, NT2B, and NT3.Formule :C32H52N8O7Degré de pureté :Min. 95%Masse moléculaire :660.81 g/molPyr-Trp-OH
CAS :Pyr-Trp-OH is a derivative of tryptophan. It has been found to be active in the brain and its metabolites have been shown to inhibit superoxide production by inhibiting the activity of hydroxylase and dismutase. Pyr-Trp-OH also inhibits serotonin synthesis, which may contribute to its antidepressant properties. Pyr-Trp-OH is an inhibitor of indoleamine 2,3 dioxygenase, an enzyme that converts tryptophan into kynurenine. This process generates hydrogen peroxide, which can lead to cell death. The conversion of tryptophan into serotonin also produces hydrogen peroxide, so it is possible that Pyr-Trp-OH may have antioxidant effects as well as antidepressant effects.Formule :C16H17N3O4Degré de pureté :Min. 95%Masse moléculaire :315.32 g/molH-Met-2-chlorotrityl resin (200-400 mesh) (Low Substitution)
