  • Publication number: 20150018566
    Abstract: The invention provides combretastatin A-4 like compounds that are modified to have enhanced tubulin binding activity and in some embodiments the ability to promote accumulation in the vasculature undergoing angiogenesis (homing activity). The compounds are based on the combretastatin A-4 skeletal structure having a tubulin-binding pharmacophore comprising two fused rings (A and B rings) in which the B ring is substituted with (a) an aromatic ring structure (C ring) and (b) a second substituent/functional group that comes off the B ring. The aromatic ring structure is typically a six membered ring phenolic or aniline structure, or may also be a fused ring structure such as a substituted or unsubstituted naphthalene.

  • Patent number: 6074838
    Abstract: The present invention provides a bacterial microorganism having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. The present invention also provides a method for the isolation and utilization of a zearalenone-degradation gene encoding a gene product having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. In another embodiment, the present invention provides for the generation of transformants into which the zearalenone-degradation gene has been introduced, thereby providing the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone to said transformants. The present invention further provides a method for detoxification of plants pre- or post-harvest using microbes having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. The invention also provides a method for detoxification of plants pre- or post-harvest using the zearalenone-degradation gene.
