Based on 1 Customer Validation

CP-96,345 is a non-peptide selective NK-1 receptor antagonist (K_i = 0.31 nM). CP-96,345 inhibits cell rolling, adhesion, and plasma extravasation, and inhibits degranulation and pancreatic MPO activity. CP-96,345 attenuates neurogenic inflammation, edema, and adhesion molecule expression. CP-96,345 attenuates static contraction- and muscle stretch-evoked pressor reflexes through blockade of NK-1 receptors in the dorsal horn. CP-96,345 impairs post-ischemic recovery of LVDevP, HR, and CF in isolated hearts and increases reperfusion fibrillation. CP-96,345 can be used for research on chronic colitis, myocardial ischemia-reperfusion injury, smoke inhalation and burn injury, acute pancreatitis, oxazolone colitis, and neurogenic inflammation.

Adaptive ImmunityRegulation of Cardiac Pump FunctionLocal Vascular Regulation

Adaptive Immunity

CP-96,345 (0.1 μM; 5 days) inhibits intestinal antigen-stimulated proliferation of CD4⁺CD25^- T cells from BALB/c mice and, to a lesser extent, the proliferation of CD4⁺ T cells from colitic SCID mice^[1].
CP-96,345 (0.01 mM; 1 h) completely inhibits neurotensin-mediated mast cell degranulation in rat colonic explants, indicating that colonic mast cell activation in response to neurotensin involves substance P release^[8].

Regulation of Cardiac Pump Function

CP-96,345 (1 μM) abolishes the beneficial effects of SP on post-ischemic recovery of ischemic contracture, LVDevP, HR, and CF, reduces the anti-fibrillatory effect of SP, and prevents the SP-mediated decrease in CK release in isolated perfused rat hearts, whereas CP-96,345 alone impairs post-ischemic recovery (LVDevP is 39% of the pre-ischemic level)^[3].

Local Vascular Regulation

CP-96,345 (1-100 nM; 15 min) competitively antagonizes Substance P (HY-P0201)-induced relaxation in noradrenaline-precontracted rabbit aortic rings, with a pA₂ of 8.15^[6].

CP 96,345 (1 µg/g; subcutaneous injection; three times per week; 8 weeks) attenuates mucosal inflammation in T cell transfer colitis, reducing the median colitis score to 3, but does not prevent weight loss^[1].
CP 96,345 (10 mg/kg; i.v.; 1 h before injury and every 12 h; 48 h) attenuates lung injury and inflammation in SB-injured mice, significantly reducing Evans blue extravasation by 31%, wet/dry weight ratio by 23%, hemoglobin by 46%, and myeloperoxidase activity by 54%^[4].
CP-96,345 (2.5 mg/kg; i.p.; single dose; 30 min before or 1 h after the first caerulein injection) effectively reduces the expression of adhesion molecules and leukocyte recruitment in the pancreas and lung in caerulein (HY-A0190)-induced acute pancreatitis in mice^[5].
CP-96345 (2.5 μg/g; i.p.; twice daily; 4 days) abolishes Oxazolone (HY-126360) colitis in CGRP^−/− mice^[7].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
