  • Patent number: 8945566
    Abstract: The invention provides a method for increasing the bioactivity (e.g. the biosafety and efficacy) of a therapeutic IgE antibody of the invention in the treatment of a patient. Methods of the invention include: i) administering to the patient a therapeutic IgE antibody in combination with at least one bioactivity-enhancing agent, ii) strategic treatment regimens and protocols for the dosing and administration of a therapeutic IgE antibody of the invention, and iii) the use of a therapeutic IgE antibody having a variable region comprising at least one antigen binding region specific for binding an epitope of an antigen wherein the epitope is not highly repetitive or is non-repetitive.

  • Patent number: 7659244
    Abstract: The present invention relates to new rapamycin derivatives for the inhibition of cell proliferation. The compounds can advantageously target two proteins in dividing cells and interfere with cell cycle. There is thus provided derivatives of rapamycin in which the 42 position of rapamycin is linked to an amino acid or a peptide through a carbamate ester linkage. These rapamycin derivatives can be synthesized by reacting 42-O-(4-Nitrophenoxycarbonyl) rapamycin and an amino acid or a free amino peptide under basic conditions. These rapamycin derivatives can be used to inhibit the cell cycle and are therefore useful for treating cell proliferation disorders.
