A cell-permeable biphenyl carbamoyl benzoate compound that potently induces the differentiation of human mesenchymal stem cells (hMSCs) into chondrocytes (EC500nM). Reversibly binds to the FC-1 fragment of filamin A and disrupts its association with CBFB leading to nuclear localization of CBFB 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 breaown without affecting the activities of MMP-3, MMP-13, and aggrecanase in primary chondrocytes or hMSCs. Group: Biochemicals. Grades: Highly Purified. Pack Sizes: 25mg. Molecular Formula: C??H??NO?, Molecular Weight: 317.3. US Biological Life Sciences.
