αvβ6 Ligand

ανβ6 Integrin ligand-1 (the ligand part of Compound 136) is a ανβ6 integrin ligand.

Tri-SM6.1 is a tridentate small-molecule ligand targeting integrin αvβ6. Tri-SM6.1 binds to integrin αvβ6 on epithelial cells to deliver conjugated α-ENaC RNAi agents.

ATTO 740 NHS ester is a near-infrared fluorescent dye and a multimodal fluorescence/photoacoustic contrast agent with excellent near-infrared emission properties and extremely high photostability. The photoacoustic signal of ATTO 740 NHS ester shows no significant decrease after continuous irradiation with a 750 nm laser for 30 min, making it suitable for in vivo fluorescence imaging and photoacoustic contrast imaging. When conjugated with the cystine knot peptide R01, ATTO 740 NHS ester enables precise detection of integrin αvβ6-positive cells and tumors in nude mouse xenograft models.

Cyclic αvβ6 (Compound c(FRGDLAFp(NMe)K)) is a αvβ6-integrin-specific cyclic nonapeptide. Cyclic αvβ6 can be coupled with ⁶⁸Ga-labeled monomeric triazacyclononane-triphosphinate (TRAP). Cyclic αvβ6 can be used in PET imaging studies for cancers including head and neck cancer and pancreatic cancer.
