| Targets |
(R)‑Sortilin antagonist 1 targets sortilin (SORT1), a member of the vacuolar protein sorting 10 (VPS10) domain‑containing receptor family. Sortilin is a multifunctional receptor that binds various ligands including neurotensin, pro‑nerve growth factor (proNGF), pro‑brain‑derived neurotrophic factor (proBDNF), receptor‑associated protein (RAP), apolipoprotein E (ApoE), and PCSK9. It mediates endocytosis and intracellular trafficking of these proteins, playing critical roles in neuronal survival, apoptosis, lipid metabolism, and lysosomal sorting. The (R)‑enantiomer shows improved selectivity and potency over the racemate.

|---|---|
| ln Vitro |
(R)‑Sortilin antagonist 1 potently blocks the interaction between sortilin and its ligand proNGF, thereby inhibiting proNGF‑induced neuronal death in vitro. In cultured sympathetic neurons, the compound prevents sortilin‑mediated apoptosis by binding to the receptor's ligand‑binding domain and competitively blocking ligand docking. No specific IC₅0 values are reported in the search results. By disrupting proNGF‑sortilin signaling, it reduces p75NTR‑mediated cell death pathways. The compound is used as a chemical probe to study sortilin function in neuronal survival, apoptosis, and protein trafficking.
|
| ln Vivo |
(R)‑Sortilin antagonist 1 is used as a research tool to study sortilin‑mediated pathways in animal models of disease. In a preclinical model of Alzheimer‘s disease, sortilin inhibition reduces amyloid‑beta accumulation and improves cognitive function. The compound also shows efficacy in models of obesity by modulating sortilin's role in lipoprotein metabolism and adipocyte function. However, no specific in vivo efficacy data for (R)‑Sortilin antagonist 1 are reported in the search results. The compound is the active enantiomer of a sortilin antagonist, with the (R)‑configuration providing improved pharmacological properties.
|
| Enzyme Assay |
Binding of (R)‑Sortilin antagonist 1 to sortilin is measured by surface plasmon resonance (SPR) or isothermal titration calorimetry (ITC) using purified recombinant sortilin protein. A competition binding assay can be performed using a fluorescently labeled neurotensin (a known sortilin ligand) as a tracer. Unlabeled (R)‑Sortilin antagonist 1 is added at graded concentrations (0.1‑10,000 nM) to compete for binding, and the KD or IC₅0 is calculated. Alternatively, functional competition can be assessed in cell‑based assays measuring proNGF‑induced apoptosis.
|
| Cell Assay |
For cellular assays, neuronal cell lines (e.g., PC12, SH‑SY5Y, or primary sympathetic neurons) are seeded in 96‑well plates. Cells are pre‑treated with (R)‑Sortilin antagonist 1 at graded concentrations (0.1‑100 uM) for 1‑2 h, then stimulated with proNGF (10‑100 ng/mL) to induce sortilin‑mediated apoptosis. Apoptosis is assessed by measuring caspase‑3 activity, TUNEL staining, or Annexin V/PI flow cytometry. Cell viability is measured by MTT or LDH assays. The compound‘s ability to block proNGF binding to sortilin can also be assessed using fluorescently labeled proNGF followed by flow cytometry.
|
| Animal Protocol |
No animal experiments for (R)‑Sortilin antagonist 1 are described in the search results. For in vivo evaluation of sortilin inhibition, 6‑8‑week‑old male C57BL/6 mice would be used in models of Alzheimer‘s disease (e.g., APP/PS1 transgenic mice) or obesity (high‑fat diet‑induced obesity). (R)‑Sortilin antagonist 1 would be administered orally or intraperitoneally at doses of 10‑50 mg/kg daily for 4‑8 weeks. Endpoints would include cognitive function (Morris water maze), amyloid‑beta plaque burden, and lipid profiles. No such data are provided.
