Activated Protein C (390-404), human is a peptide of the activated protein C (a vitamin K-dependent serine protease), potently inhibits APC anticoagulant activity.

CCR2 antagonist 4 (Teijin compound 1) is a potent and specific CCR2 antagonist, with IC50s of 180 nM for CCR2b. CCR2 antagonist 4 potently inhibits MCP-1-induced chemotaxis with an IC50 of 24 nM.

CALP3, a Ca2+-like peptide, is a potent Ca2+ channel blocker that activates EF hand motifs of Ca2+-binding proteins. CALP3 can functionally mimic increased [Ca2+]i by modulating the activity of Calmodulin (CaM), Ca2+ channels and pumps. CALP3 has the potential in controlling apoptosis in diseases such as AIDS or neuronal loss due to ischemia.

L-655708 is a potent α5 subunit-selective GABAA receptor inverse agonist (Ki=0.45 nM).

NBI-74330 is a potent antagonist for CXCR3, and exhibits potent inhibition of (125I)CXCL10 and (125I)CXCL11 specific binding with Ki of 1.5 and 3.2 nM, respectively.

HET0016 is a potent and selective 20-hydroxyeicosatetraenoic acid (20-HETE) synthase inhibitor, with IC50 values of 17.7 nM, 12.1 nM and 20.6 nM for recombinant CYP4A1-, CYP4A2- and CYP4A3-catalyzed 20-HETE synthesis, respectively. HET0016 also is a selective CYP450 inhibitor, which has been shown to inhibit angiogenesis and tumor growth.

Z-Ala-Ala-Asn-AMC (Cbz-Ala-Ala-Asn-AMC) is the legumain substrate. Overexpressed legumain in 293 HEK-Leg cells potently cleaved CBZ-Ala-Ala-Asn-AMC.

JNJ16259685 is a selective antagonist of mGlu1 receptor, and inhibits the synaptic activation of mGlu1 in a concentration-dependent manner with IC50 of 19 nM.

USP7/USP47 inhibitor is a selective ubiquitin-specific protease 7/47 (USP7/USP47) inhibitor, with EC50s of 0.42 μM and 1.0 μM, respectively.

MK-2894 is a potent, selective, orally active and high affinity (Ki=0.56 nM) full antagonist against E prostanoid receptor 4 (EP4 receptor) (IC50=2.5 nM). MK-2894 possesses potent anti-inflammatory activity in animal models of pain/inflammation and can be used for the research of arthritis.
