SAP15 acetate  (Synonyms: Synthetic anti-inflammatory peptide 15 acetate)

SAP15 (Synthetic anti-inflammatory peptide 15) acetate is a synthetic anti-inflammatory peptide consisting of 15 amino acids designed from human beta-defensin 3. SAP15 acetate has the ability to penetrate cells and is able to induce downregulation of intracellular inflammation. SAP15 acetate inhibits inflammation by inhibiting the phosphorylation of HDAC5 and thereby reducing the phosphorylation of NF-κB p65. SAP15 acetate inhibits HDAC5 and NF-κB p65 phosphorylation in LPS (HY-D1056)-induced macrophages. SAP15 acetate increases the expression of aggrecan and type II collagen and decreases the expression of osteocalcin in LPS-induced chondrocytes. SAP15 acetate can be used in the study of inflammation regulation and anti-inflammatory therapy of biomaterials^[1].
