General description

A cell-permeable biphenylcarbamoylbenzoate compound that potently induces the differentiation of human mesenchymal stem cells (hMSCs) into chondrocytes (EC50 = 100 nM). Reversibly binds to the FC-1 fragment of filamin A and disrupts its association with CBFβ leading to nuclear localization of CBFβ and binding to runt-related transcription factor (RUNX) to regulate chondrogenesis. Also reported to inhibit cytokine-induced release of nitric oxide (NO) and glycosaminoglycan (GAG). Exhibits chondroprotective properties and promotes cartilage repair in murine osteoarthritis models. Shown to up-regulate the levels of TIMP1, collagen, and aggrecan thereby blocking further matrix breakdown without affecting the activities of MMP-3, MMP-13, and aggrecanase in primary chondrocytes or hMSCs.
