Product Description
ENMD-1068 is a selective protease-activated receptor 2 (PAR2) antagonist. ENMD-1068 reduces hepatic stellate cell activation and collagen expression by inhibiting TGF-β1/Smad signaling. ENMD-1068 can also inhibit the proliferation of endometrial cells and cause apoptosis of epithelial cells in lesions. ENMD-1068 may be utilized in study/research of endometriosis and liver fibrosis.
ENMD-1068 HCl (CAS#: 789488-77-3), also known as ENMD-1068 hydrochloride, is a selective protease-activated receptor 2 (PAR2) antagonist with anti-angiogenic and anti-inflammatory activities. It reduces hepatic stellate cell activation and collagen expression by inhibiting TGF-β1/Smad signal transduction. ENMD-1068 HCl inhibits the development of endometriosis in a mouse model. The compound has a molecular weight of 283.41 g/mol and a molecular formula of C15H29N3O2.
Biological Activity I Assay Protocols (From Reference)
Targets
ENMD-1068 targets protease-activated receptor 2 (PAR2), a G protein-coupled receptor that is activated by proteolytic cleavage and is involved in inflammation, pain, angiogenesis, and fibrosis. By acting as a selective antagonist at PAR2, ENMD-1068 blocks PAR2-mediated signaling pathways. The compound reduces hepatic stellate cell activation and collagen expression through the inhibition of TGF-β1/Smad signal transduction. ENMD-1068 also inhibits the proliferation of endometrial cells and induces apoptosis in lesional epithelial cells.
ln Vitro
EnMD-1068 (10 mM; 24 hours) reduces the release of calcium from HSCs induced by trypsin or SLIGRL-NH2. TGF-β1/Smad signaling is important for HSC activation and collagen synthesis. ENMD-1068 (10 mM) prevents this signaling in primary HSCs [1].
In vitro, ENMD-1068 HCl acts as a selective antagonist at PAR2 with an IC50 of 5000 μM. It reduces hepatic stellate cell activation and collagen expression by inhibiting TGF-β1/Smad signaling. The compound inhibits the proliferation of endometrial cells and induces apoptosis in lesional epithelial cells. These in vitro studies confirm the compound's anti-inflammatory, anti-fibrotic, and anti-angiogenic activities. ENMD-1068 HCl has also been used to determine the pathway responsible for paw edema induced by venom serine protease.
ln Vivo
Mice's liver fibrosis is inhibited by ENMD-1068 (25, 50 mg/kg; intraperitoneal injection; twice weekly for 4 weeks) [1]. One intraperitoneal injection of ENMD-1068 (25, 50 mg/kg) administered once daily for five days suppresses the proliferation of platelets controlled by endometriosis and dose-dependently lowers MCP-1 and IL-6 levels [2]. lasting five days) will cause mice's cell transplantation index to rise and their epithelial cell swelling to decrease [2].
In vivo, ENMD-1068 HCl has demonstrated efficacy in animal models. It inhibits the development of endometriosis in a mouse model. The compound has been used as a PAR2 antagonist to determine the pathway responsible for paw edema induced by Crotalus durissus terrificus venom serine protease (Cdtsp 2). ENMD-1068 HCl's anti-angiogenic and anti-inflammatory activities support its potential for treating endometriosis and fibrotic diseases. Further in vivo studies would be required to fully characterize its therapeutic potential.
Enzyme Assay
In vitro enzyme/receptor binding assays for ENMD-1068 HCl are radioligand binding assays using membrane preparations from cells expressing recombinant human PAR2. The compound's binding affinity is determined by its ability to displace a labeled PAR2 ligand. Functional assays such as calcium mobilization assays can also be used to measure the compound's antagonist activity at PAR2. The IC50 for inhibition of PAR2-mediated signaling is determined from dose-response curves. These assays confirm the compound's selective PAR2 antagonism.
Cell Assay
Western Blot Analysis[1]
Cell Types: Hepatic stellate cells (HSC) (stimulated by TGF-β1)
Tested Concentrations: 10 mM
Incubation Duration: 24 hrs (hours)
Experimental Results: Inhibition of TGF-β1-induced α-SMA, Col α1(І), Col Expression of α1(III) and Smad2/3 C-terminal phosphorylation.
In vitro cellular assays for ENMD-1068 HCl are performed using various cell types, including hepatic stellate cells, endometrial cells, and other PAR2-expressing cells. Cells are treated with ENMD-1068 HCl and stimulated with PAR2 agonists (e.g., trypsin or SLIGRL peptide). Calcium mobilization is measured using fluorescent calcium indicators to assess PAR2 activation. Hepatic stellate cell activation is assessed by measuring collagen expression and TGF-β1/Smad signaling by Western blotting or quantitative PCR. Endometrial cell proliferation is measured using MTT assays, and apoptosis is evaluated using annexin V staining.
Animal Protocol
Animal/Disease Models: ICR mouse (8 weeks old; CCl4-induced liver fibrosis model) [1].
Doses: 25, 50 mg/kg
Route of Administration: intraperitoneal (ip) injection; twice a week for 4 weeks.
Experimental Results: Collagen deposition was Dramatically weakened.
Animal/Disease Models: Mice with surgically induced endometriosis [2].
Doses: 25, 50 mg/kg
Route of Administration: intraperitoneal (ip) injection; one time/day for 5 days
Experimental Results: Reduction in observed lesion volume in a dose-dependent manner. Inhibits the expression of IL-6 and MCP-1. Reduce the proliferation rate of endometriotic cells and increase the percentage of apoptotic epithelial cells in the lesions.
In vivo animal experiments for ENMD-1068 HCl have been conducted in mouse models of endometriosis and inflammation. In the endometriosis model, mice are administered ENMD-1068 HCl via intraperitoneal or oral administration, and the development of endometriotic lesions is assessed. In the paw edema model, mice are injected with venom serine protease, and paw swelling is measured in the presence or absence of ENMD-1068 HCl. These studies evaluate the compound's efficacy in reducing inflammation and disease progression.
ADME/Pharmacokinetics
ENMD-1068 HCl has a molecular weight of 283.41 g/mol and a molecular formula of C15H29N3O2. The compound is soluble in DMSO at concentrations up to 245 mg/mL (864.47 mM). For in vivo administration, it can be formulated in 10% DMSO + 90% Saline at concentrations up to 10 mg/mL (35.28 mM). The compound is stable as a pure form at -20°C for up to 3 years and in solution at -80°C for up to 1 year. Detailed pharmacokinetic properties have not been extensively reported.
Toxicity/Toxicokinetics
ENMD-1068 HCl has been evaluated in preclinical studies and has been reported to be well-tolerated at effective doses. No significant toxicity has been reported in the available literature. As a selective PAR2 antagonist, ENMD-1068 HCl may have a favorable safety profile with reduced risk of off-target effects. However, comprehensive toxicology studies would be necessary to fully assess the compound's safety for clinical development. The compound is a research tool for studying PAR2 biology.
