R-M-1192	(Tyr⁸)-Substance P,CAS:55614-10-3	(Tyr⁸)-Substance P,CAS:55614-10-3 from ruixi.This analog of substance P was synthesized for iodination.	price>
R-M-1193	Substance P (1-7),CAS:68060-49-1	This amino-terminal fragment of substance P exerts depressor and bradycardic effects when applied to the nucleus tractus solitarius. It was also shown that this fragment, contrary to substance P, may reduce signs of opioid withdrawal in mice.	price>
R-M-1194	Substance P (1-9),CAS: 57468-17-4	Substance P (1-9) is nonapeptide, which decreases the inactivation of substance P by the guinea-pig ileum and urinary bladder. Subtance P is responsible for a number of excitatory effects on both central and peripheral neurons.	price>
R-M-1196	Substance P (4-11),CAS: 53749-60-3	The octapeptide substance P (4-11), PQQFFGLM-amide, seems to be more active than the natural peptide in various pharmacological tests in vitro and in vivo. Octa-substance P was shown to be an agonist of the NK1 receptor, IC₅₀ 15 nM.	price>
R-M-1198	Suc-Val-Pro-Phe-SBzl,CAS: 95192-51-1	The thiobenzyl ester substrate Suc-VPF-SBzl is significantly more sensitive than the corresponding p-nitroanilide, with kcat/Km values ranging from 0.5 to 8.3 · 10⁶ M⁻¹s⁻¹ for chymotrypsin, human leukocyte cathepsin G, human skin chymase, and rat mast cell proteases.	price>
R-M-1200	Syntide 2 trifluoroacetate salt,CAS:108334-68-5	Ca²⁺ calmodulin-dependent protein kinase II and Ca²⁺ phospholipid-dependent protein kinase (PKC) were selectively assayed using syntide 2 as substrate. The sequence of syntide 2 is homologous to phosphorylation site 2 in glycogen synthase.	price>
R-M-1256	Z-His-Phe-Phe-OEt,CAS : 13053-61-7	zHFFe, a good substrate for pepsin. Hertel et al identified zHFFe as a potent inhibitor of zero-trans glucose flux with a Ki of 26 μM. Similar to HIV protease inhibitors, transport inhibition by this peptide was acute, non-competitive, and reversible. Within a Xenopus oocyte expression system, zHFFe acutely and reversibly inhibited GLUT4-mediated glucose uptake, whereas GLUT1 activity was unaffected at concentrations as high as 1 mM.	price>
R-M-1258	Z-Ile-Glu-Thr-Asp-AFC,CAS :219138-02-0	The fluorogenic substrate Z-IETD-AFC corresponds to one of the cleavage sites of the inactive 32 kD caspase-3 precursor (amino acids 172-175). Substrate for granzyme B.	price>
R-M-1264	Z-Tyr-Lys-Arg-pNA·2 TFA,CAS:108318-36-1	The chromogenic substrate Z-YKR-pNA is cleaved by proteinase yscF, now known as the Kex2 endoprotease kexin, a membrane-bound yeast enzyme responsible for processing of the α-factor precursor protein.	price>
R-M-1311	Leu-Enkephalin Amide Peptide,Cas:60117-24-0	Enkephalin, one of several naturally occurring morphinelike substances (endorphins) released from nerve endings of the central nervous system and the adrenal medulla.This is an endogenous neurotransmitter.	price>
