  • Publication number: 20090276359
    Abstract: Described herein is a multi-product-multi-channel payment platform system and apparatus that extends the capability of current online banking/funds-transfer systems. Different types of financial accounts are modeled in a financial management system to enable types of online, electronic funds transfer transaction that were not previously possible. Among novel elements of the system and apparatus disclosed is the enablement of real-time application of rules to different types of financial accounts and/or products across channels, such as how much money may be deposited or withdrawn in a period of time.

  • Publication number: 20090220786
    Abstract: Methods for modulated degenerative transfer living polymerization and isotactic-atactic stereoblock and stereogradient poly(olefins) thereby Abstract A method of producing a multiblock, stereoblock polyolefin having substantially uniform microstructure is disclosed. The method includes contacting a Ziegler-Natta pre-catalyst with a co-catalyst and an olefin to polymerize the olefin and form a first stereoblock, adding a methyl donator that changes the stereoregularity of the polymerization, and polymerizing the olefin to form a second stereoblock. The methods of the present invention allow for the production of poly(olefin)s having predictable degrees of incorporation of stereoerrors of a known type. The methods allows for the production of a variety of poly(olefin) microstructures, ranging from stereoblock to stereogradient poly(olefin)s and poly(olefin)s having fully isotactic to fully atactic microstructures.

  • Publication number: 20080318906
    Abstract: Bisphosphonate compounds and related methods of making and using are disclosed, including pyridinium-1-yl, quinolinium-1-yl, and related compounds. The activity of compounds is disclosed in the context of functional assays such as Leishmania major farnesyl diphosphate synthase (FPPS) inhibition, Dictyostelium discoideum growth inhibition, human gamma delta T cell activation, and bone resorption. The applicability of bisphosphonate compounds in the context of parasitic infections, for example against trypanosomes, is disclosed. Further potential applications of the invention are disclosed regarding the treatment of one or more conditions such as bone resorption disorders, cancer, bone pain, infectious diseases, and in immunotherapy.

  • Publication number: 20080255070
    Abstract: The disclosure provides, inter alia, novel bisphosphonate compounds and methods of making and using such compounds. In certain embodiments, compounds of the invention include bisphosphonates that are capable of selectively inhibiting one or more of farnesyl diphosphate synthase (FPPS), geranylgeranyl diphosphate synthase (GGPPS), and decaprenyl pyrophosphate synthase (DPPS). In preferred embodiments, compounds of the invention are capable of selectively inhibiting two or more of FPPS, GGPPS, and DPPS. In embodiments, compounds and methods of the invention demonstrate superior activity levels, such as in the anti-cancer context, immunostimulation context, and other contexts, which in several cases exceed the activity levels of previous generation bisphosphonate drugs by orders of magnitude. In embodiments, the invention provides compounds and methods in connection with research and therapeutic applications, e.g.

  • Publication number: 20070275931
    Abstract: The invention provides, inter alia, novel bisphosphonate compounds and methods of making and using. In embodiments, the invention provides compounds and methods in connection with research and therapeutic applications, e.g., for tumor cell growth inhibition, activation of gammadelta T cells, inhibition of farnesyldiphosphate (FPPS) and/or undecaprenyldiphosphate synthase enzymes, bone resorption diseases, cancer, immune disorders, immunotherapy, and infectious diseases. In regards to certain embodiments, a surprising advance has been the recognition that certain structural features can significantly enhance the activity of the compounds. For example, the presence of particular cationic species e.g., phosphonium, sulfonium, and arsonium moieties can contribute to desirable functional activity when positioned near a bisphosphonate moiety. In other embodiments of non-nitrogen containing bisphosphonates, terphenyl and benzyl bisphosphonate compounds and methods are provided. Further variations are also provided.
