AdipoGen 4-Methylumbelliferone
Chemical. CAS 90-33-5. Formula C10H8O3. MW 176.17. 4-Methylumbelliferone 4-MU is a selective inhibitor of hyaluronan HA by depletion of UDP-glucuronic acid, the common substrate for HA synthesis and downregulation of hyaluronan synthase 2 and 3, MMP2 and MMP9. Since hyaluronan HA is a major component of the extracellular matrix that is synthesized in excess in cancer tissues, 4-MU has been shown to have anti-cancer activity and is involved in angiogenesis, invasion and metastasis of cancer. Fluorescent pH indicator, that is highly fluorescent in alkaline solution. Exhibits a blue fluorescence at pH7. The fluorescence intensity is pH dependent and increases to a maximum at pH10 plateau above pH10. The fluorescence at pH10.3 is approximately 100 times as intense as at pH7. Spectral data lambdaex=360nm lambdaem=448nm pH > 9.
