Product Overview:
4-Methylumbelliferone (4-ΜU) is a synthetic coumarin with diverse biological activities.{52251,52252,27251} It inhibits hyaluronic acid synthesis in PC3-ML and DU145 cells (IC50s = ~0.4 mM for both).{52251} 4-MU inhibits the growth of PC3-ML, DU145, C4-2B, LNCaP, and LAPC-4 prostate cancer cells (IC50s = 0.2-0.4 mM) and invasion and chemotactic motility of PC3-ML and DU145 cells in vitro. It reduces tumor growth and microvessel density in a PC3-ML mouse xenograft model when administered at doses of 225 and 450 mg/kg twice per day. 4-ΜU is active against H. pylori and V. cholerae in vitro (MICs = 59 and 100-200 μg/ml, respectively).{52252} Derivatives and conjugates of 4-ΜU have been used as fluorogenic substrates to measure enzyme activity.{39610,26284,47304} Upon enzymatic cleavage, 4-ΜU is released and its fluorescence can be used to quantify enzyme activity. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high pH (7.12-10.3), respectively, and an emission maximum ranging from 445 to 455 nm, increasing as pH decreases.{27251}

Cayman Chemical's mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.

Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.

Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.

Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
