  • Publication number: 20210361772
    Abstract: Covalent conjugation of an alpha amino acid ester to a modulator of the activity of a target intracellular enzyme or receptor, wherein the ester group of the conjugate is hydrolysable by one or more intracellular carboxylesterase enzymes to the corresponding acid, leads to accumulation of the carboxylic acid hydrolysis product in the cell and enables improved or more prolonged enzyme or receptor modulation relative to the unconjugated modulator.

  • Publication number: 20190353653
    Abstract: This invention relates to the diagnosis of disease conditions, such as cancer and autoimmune disease, by the analysis of cell-free nucleosomes in samples from individuals. Methods of the invention may include contacting cell-free nucleosomes from a biological fluid sample obtained from the individual with an antibody that binds specifically with a modified histone protein. Binding of the antibody to the nucleosomes is indicative that the individual has the disease condition.
