Chemical Structure
Pittsburgh Compound B
Synonym(s): PiB; 6-OH-BTA-1
- CAS No.: 566169-93-5
- Formula:C14H12N2OS
- Molecular Weight:256.33
IUPAC Name: 2-(4-(methylamino)phenyl)benzo[d]thiazol-6-ol
InChIKey: ZQAQXZBSGZUUNL-UHFFFAOYSA-N
SMILES: OC1=CC=C2N=C(SC2=C1)C3=CC=C(C=C3)NC
Biological Activity: Pittsburgh Compound B (PiB) is a blood-brain barrier-permeable, specific Aβ deposition PET tracer that binds to Aβ(1-40) fibrils with a Ki value of 678.4 nM. Through click chemical modification (a clickable Pittsburgh Compound B derivative is prepared by introducing a PEG3 linker and an alkynyl group at the 6-hydroxy site of Pittsburgh Compound B, followed by covalent conjugation with azide-labeled fluorescent dyes or affinity tags via copper-catalyzed azide-alkyne cycloaddition (CuAAC)), Pittsburgh Compound B and its conjugates can be used for fluorescence imaging, ultrastructural studies, and enrichment and characterization of Aβ complexes. Pittsburgh Compound B is applicable to Alzheimer's disease research[1][2].
