Gustatory receptors required for sensing umbelliferone in Drosophila melanogaster
Insect Biochemistry and Molecular Biology, 2015Studies of taste modality using the animal model Drosophila melanogaster have elucidated a number of uncharacterized mechanisms of sensory responses. Gustatory receptors expressed in taste organs are not only responsible for the acceptance and rejection of different foods, but are also involved in the process of selecting an oviposition site.

Anti-inflammatory and proapoptotic effects of umbelliferone in colon carcinogenesis
Human & Experimental Toxicology, 2016Colorectal cancer (CRC) is a serious health problem throughout the world. 5-Flurouracil, the first-line chemotherapy of colorectal cancer often produces more toxicity to neighboring cells; however, it is still used for CRC treatment. To overcome this, umbelliferone (UMB), a less toxic bioflavonoid has been used to test its anticancer effects on animal ...

Determination of Coumarin and Umbelliferone Mixtures in Whole Blood by Spectrophotofluorometry
Journal of Pharmaceutical Sciences, 1976A spectrophotofluorometric method is described for the quantitative analysis of coumarin, umbelliferone, and mixtures thereof in whole blood. The two drugs were selectively isolated from blood by solvent extraction. Analysis of the isolated coumarin was based on the measurement of the fluorophore at activation and emission wavelengths of 361 and 491 nm,

Umbelliferone Alleviates Myocardial Ischemia: the Role of Inflammation and Apoptosis
Inflammation, 2017The present study was to investigate cardioprotective effects of umbelliferone (Umb) on coronary artery ligation-induced myocardial ischemia. The model of myocardial ischemia (MI) was induced by ligatured the left anterior descending coronary artery of SD rats.

The Metabolism of Umbelliferone and Herniarin in Rats and by the Rat Intestinal Microflora
Xenobiotica, 19711. The metabolism of umbelliferone (7-hydroxycoumarin) and herniarin (7-methoxycoumarin) was studied in rats after oral and intraperitoneal administration.2. Umbelliferone was excreted in the urine partly unchanged but mainly as a glucuronide and/or sulphate conjugate.

Magnetic activated release of umbelliferone from lipid matrices
International Journal of Pharmaceutics, 2010Lipid matrices containing dispersed superparamagnetic iron oxide (SPIO) particles were investigated as a magnetic field-responsive drug delivery system. Lipid matrices were prepared by combining myristyl alcohol, fatty acid coated SPIO particles, and umbelliferone (UMB).

Fluorescence of some simple umbelliferone derivatives
Collection of Czechoslovak Chemical Communications, 1979The absorption and fluorescence spectra of umbelliferone were studied; it was found that in the excited state the basicity of the α-pyrone part of the molecule increases to such an extent that it exceeds that of the phenolate oxygen of the molecule. This is responsible for the neutral nondissociated form of umbelliferone being only in nonpolar medium ...
