WYRGRLC
WYRGRLC is a type II collagen-targeting peptide. WYRGRLC specifically binds to type II collagen α1 in articular cartilage in a sequence-dependent manner. WYRGRLC inhibits the binding of WYRGRL-displaying phage (C1-3) to articular cartilage in a sequence-specific manner. WYRGRLC can act as a retention enhancer to improve the cartilage-targeting ability of polymeric nanoparticles and liposomal nanoplatforms, facilitating the delivery of Rapamycin (HY-10219) to chondrocytes. WYRGRLC can be used in studies related to osteoarthritis.

Biological Activity
WYRGRLC (0-1 μM) potently and sequence-specifically inhibits the binding of phage displaying WYRGRL to bovine cartilage, with an IC50 of 140 nM[1].
WYRGRLC (15 mg; 1 h) specifically binds to type II collagen α1 chain, which is an abundant extracellular matrix protein in bovine cartilage[1].
WYRGRLC-modified C6@PEG-PA@P-Lipo enhances targeted cellular uptake by rat chondrocytes (RCCs)[2].
WYRGRLC-modified P-Lipo can adhere to the surface layer of porcine cartilage tissue, but its deep penetration ability is limited due to its large particle size[2].
