  • Patent number: 9842474
    Abstract: Methods, systems, and computer programs are presented for adjusting bonus winning odds while playing an online slots game. One method includes an operation for receiving user input during a session of an online slots game, where the user input is defined to spin wheels of the online slots game. In addition, the method includes an operation for defining an initial tier and one or more additional tiers for play of the online slots game during the session, each tier being assigned an odds value that changes with each assigned tier, and each tier being defined to have a set of spins. Further, the method includes operations for assigning tiers with changed odds when an option to play a bonus game is not presented during the predefined set of spins for each tier, and for assigning the initial tier upon determining that the bonus game was played during the session.

  • Publication number: 20170291887
    Abstract: Filamenting temperature-sensitive mutant Z (FtsZ) protein plays a crucial role in the bacterial cell division machinery and is a validated drug target for antibacterial agents. The present invention relates to FtsZ-interacting compounds that possess a 2,4,6-trisubstituted pyrimidine scaffold. Some of these compounds possess potent anti-staphylococcal properties and potent antibacterial activities against clinically isolated MRSA strains. Compounds have been identified to exhibit low spontaneous frequency of resistance, low toxicity as well as the ability to rescue G. mellonella larvae infected with lethal dose of the MRSA ATCC 43300 strain. Characterization by saturation transfer difference NMR, light scattering assay and GTPase hydrolysis assay with purified S. aureus FtsZ protein verified the interaction of 2,4,6-trisubstituted pyrimidine with the FtsZ protein, further confirmed by observations of iconic filamentous cell phenotype and mislocalization of the Z-ring formation.

  • Patent number: 9611256
    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.
