Chemical Structure
TPT-260
Synonym(s): TPU260
- CAS No.: 769856-81-7
- Formula:C8H12N4S3
- Molecular Weight:260.40
IUPAC Name: thiophene-2,5-diylbis(methylene) dicarbamimidothioate
InChIKey: XGDUNTSTRCLVLN-UHFFFAOYSA-N
SMILES: NC(SCC1=CC=C(CSC(N)=N)S1)=N
Biological Activity: TPT-260 (TPU260), a thiophene thiourea derivative, is a retromer complex stabilizer against thermal denaturation (Kd = ~5 µM). TPT-260 increases the levels of retromer proteins, shifts amyloid-precursor protein (APP) away from the endosome, and decreases the pathogenic processing of APP. TPT-260 inhibits TLR4 upregulation, IKKβ phosphorylation, NF-κB p65 nuclear translocation, and NLRP3 inflammasome formation. TPT-260 improves retromer-mediated cargo trafficking, reduces brain infarct area, and decreases amyloid plaque deposition. TPT-260 exhibits minimal cytotoxicity to primary microglia at tested concentrations. TPT-260 can be used for the research of inflammatory bowel disease, ischemic stroke and Alzheimer's disease[1][2][3][4].
