Fosaprepitant dimeglumine (MK-0517) is the dimeglumine salt form of fosaprepitant, a water-soluble, N-phosphorylated prodrug of aprepitant with antiemetic activity. Upon intravenous administration and rapid conversion to aprepitant, this agent selectively binds to human substance P neurokinin 1 (NK1) receptors in the central nervous system (CNS), inhibiting receptor binding of endogenous substance P and preventing substance P-induced emesis.

Aprepitant is a Substance P Neurokinin-1 Receptor Antagonist. The mechanism of action of aprepitant is as a Neurokinin 1 Antagonist, and Cytochrome P450 3A4 Inhibitor, and Cytochrome P450 2C9 Inducer, and Cytochrome P450 3A4 Inducer.

gamma-preprotachykinin amide (72-92) acetate is a 21 amino acid peptide belonging to the tachykinin (TK) family and including neurokinin A (NKA) in its C-terminal sequence. gamma-preprotachykinin amide (72-92) acetate possesses higher affinity than NKA for central NK-2 receptors; it shows lower affinity for NK-1 receptors, however, it potently stimulates salivary secretion, which is mediated by NK-1 receptor activation.

Prepro VIP (111-122), human acetate is a prepro-vasoactive intestinal polypeptide (VIP)–derived peptide, corresponding to residues 111-122.

Prepro-Atrial Natriuretic Factor (26-55) (human) is a polypeptide that increases cyclic GMP levels in the renal cortex and medulla, and enhances renal guanylate cyclase activity [1].

Prepro-TRH-(160-169), a connecting peptide of the thyrotropin-releasing hormone prohormone (pro-TRH), enhances TRH-induced thyrotropin (TSH) release [1].

gamma-preprotachykinin amide (72-92) is a useful organic compound for research related to life sciences. The catalog number is T9417 and the CAS number is 114882-65-4.

Prepro VIP (111-122), human, is a peptide derived from prepro-vasoactive intestinal polypeptide (VIP), corresponding to residues 111-122.

Prepro VIP (81-122), human, is a peptide derived from prepro-vasoactive intestinal polypeptide (VIP), corresponding to residues 81-122.

rac-Aprepitant-d4 (enantiomer) is a deuterated compound of rac-Aprepitant. rac-Aprepitant has a CAS number of 170729-80-3.

Preprosomatostatin (25-34) is a peptide.

Fosaprepitant-d4 Dimeglumine is a deuterated compound of Fosaprepitant Dimeglumine. Fosaprepitant Dimeglumine has a CAS number of 265121-04-8. Fosaprepitant Dimeglumine is the dimeglumine salt form of fosaprepitant, the water-soluble, N-phosphorylated prodrug of aprepitant, with antiemetic activity. Upon intravenous administration and rapid conversion to aprepitant, this agent binds selectively to the human substance P neurokinin 1 (NK1) receptors in the central nervous system (CNS). This inhibits receptor binding of the endogenous substance P and prevents substance P-induced emesis.

Prepro-ANF (56-92), human, a precursor to the human atrial natriuretic factor, activates guanylate cyclase by specifically enhancing particulate guanylate cyclase activity within the renal membrane and unit [1].

Preptin, an osteogenic peptide derived from pancreatic beta-cells, spans amino acids Asp 69 to Leu 102 within pro-IGF-II [1].

Salidroside is a bioactive phenolic glycoside compound isolated from Rhodiola rosea and is a prolyl endopeptidase inhibitor. Salidroside can alleviate cachexia symptoms in a tumor cachexia mouse model by activating mTOR signaling and protect dopaminergic neurons by enhancing PINK1 Parkin-mediated mitochondrial autophagy. Salidroside can also inhibit the growth of cancer cells by regulating the CDK4-cyclin D1 pathway to block the G1 phase and or regulating the Cdc2-cyclin B1 pathway to block the G2 phase.

KYP-2047 is a very potent, selective Prolyl oligopeptidase (POP) inhibitor.

NH2-UAMC1110 TFA is a derivative of UAMC1110 bearing an aminobutoxy group for the synthesis of FAPI-QS. UAMC1110 is a novel selective fibroblast-activated protein (fap) inhibitor exhibiting low nanomolar inhibition of the related dipeptidyl peptidases (dpps), dppiv, dpp9, dppii, and (prep). dppiv, dpp9, dppii, and (prep).
