Angstrom6

Angstrom6 (A6 Peptide) is an 8 amino-acid peptide derived from single-chain urokinase plasminogen activator (scuPA) and interferes with the uPA/uPAR cascade and abrogates downstream effects. Angstrom6 binds to CD44 resulting in the inhibition of migration, invasion, and metastasis of tumor cells, and the modulation of CD44-mediated cell signaling[1][2].
