  • Publication number: 20150011513
    Abstract: 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.

  • Patent number: 8930899
    Abstract: A method for building an application installation repository is disclosed herein. In one embodiment a build directory comprising a plurality of application objects is evaluated. Artifact generation rules may also be evaluated with respect to the application objects and the build directory. Object groupings, each comprising one or more application objects of the plurality of application objects, are defined according to the evaluations of the artifact generation rules and the hierarchical directory structure and artifacts are generated according to the object groupings. An installable application is generated that includes the generated artifacts. Artifacts may be further grouped into sharable units and assemblies according to rules and organization of application objects in the build directory. A delta build including only artifacts corresponding to modified files and correspondingly modified metadata may also be generated according to methods disclosed herein.

  • Patent number: 8829942
    Abstract: A comparator is provided and the comparator includes a comparing input unit and a latching unit. Wherein, the comparing input unit has a first input receiving a first comparing signal and has a second input receiving a second comparing signal. The comparing input unit drives a first intermediate node signal at a first intermediate node depending on the first comparing signal according to a first strobe signal, and the comparing input unit drives a second intermediate node signal at a second intermediate node depending on the second comparing signal according to the first strobe signal. The latching unit determines a comparing result according to at least one of the first intermediate node signal and the second intermediate node signal. In addition, the latching unit latches the comparing result according to a second strobe signal.

  • Patent number: 8710097
    Abstract: Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over-expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.

  • Patent number: 8659461
    Abstract: The present invention provides a pipelined-successive approximation register (SAR) analog-to-digital converter (ADC) circuit with decoupled flip-around MDAC, capacitive attenuation solution and self-embedded offset cancellation. The flip-around MDAC architecture is built for low inter-stage gain implementation. A capacitive attenuation solution is provided for minimizing the power dissipation and optimizing conversion speed. The design reuses SAR ADC to perform offset cancellation, which significantly saves calibration area, power and time.
