ALKYNE-, AZIDE- AND TRIAZOLE-CONTAINING FLAVONOIDS AS MODULATORS FOR MULTIDRUG RESISTANCE IN CANCERS
Publication number: 20150011513Abstract: A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-containing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRP1-overexpressed cell line (2008/MRP1) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRP1- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRP1 and BCRP transporters.Type: ApplicationFiled: March 1, 2013Publication date: January 8, 2015Inventors: Larry Ming Cheung Chow, Tak Hang Chan, Kin Fai Chan, Iris Lai King Wong, Man Chun Law -

Publication number: 20070016037Abstract: Flow information (e.g., velocity and acceleration) and/or pressure gradient information are determined with ultrasound. Both velocity and acceleration are simultaneously estimated using a model and least squares analysis. Anti-aliasing of velocity information may be provided using the model and least squares analysis. Pressure gradient is calculated from velocity information automatically, more likely providing consistent measurements. Consistency may be increased further by automatically positioning a region of interest in either a multidimensional spatial image or a spatial-temporal image. A parametric image of pressure gradient for each spatial location within the image is generated as well as a delta pressure curve. Any single one or combinations of two or more of the features described above may be used.Type: ApplicationFiled: June 6, 2005Publication date: January 18, 2007Inventors: Helene Houle, Liexiang Fan, Matthew Holladay, King Wong, Wayne Gueck
