Benzene Ring Bonded Directly To One Of The Chalcogens Patents (Class 558/210)
  • Patent number: 8658600
    Abstract: Disclosed is a general methodology to create nano fibers of therapeutic molecules that have a dual role, as both the delivery vehicle and the drug itself. It is shown that with proper molecular design, the integration of enzymatic reaction and self-assembly provides a powerful method to create molecular hydrogels of clinically-used therapeutics without compromising their bioactivities. In addition, the results disclosed herein demonstrate enzyme-instructed self-assembly as a facile strategy for generating the supramolecular hydrogels of molecules that inherently have poor solubility in water. For example, by covalently connecting paclitaxel with a motif that is prone to self-assemble, a hydrogel of paclitaxel can be formed without compromising the activity of the paclitaxel.

  • Patent number: 8022239
    Abstract: A novel class of compounds to inactivate autotaxin enzymes is provided. Such compounds include mono- and di-fluoromethylphenyl C12-C18 phosphodiesters and exhibit reactivity with autotaxin to ultimately reduce the size of the reactive sites thereon to prevent conversion of lysophosphatidyl choline to lysophophatidic acid. Furthermore, such compounds are non-cytotoxic, and can be incorporated within delivery forms for human ingestion. As such, these compounds accord an excellent manner of potentially reducing generation of certain cancers attributable to the presence of naturally occurring autotaxin within the human body. Methods of producing such novel compounds are encompassed within this invention as well as methods of inactivating autotaxin to certain degrees therewith.
