  • Patent number: 10688105
    Abstract: A method for treating a subject suffering from refractory rheumatoid arthritis includes the step of administering an effective amount of a quinonemethide triterpenoid or a pharmaceutically tolerable salt, solvate or anhydrate thereof to the subject. Also is a method for inducing autophagy in a synovial fibroblast, and a method of inducing calcium mobilization in a synovial fibroblast. Further a pharmaceutical composition includes an effective dose of a quinonemethide triterpenoid and an anti-arthritis compound. The quinonemethide triterpenoid is suitable to treat refractory rheumatoid arthritis (RA) in particular ABC-protein-dependent RA and apoptosis-deficient RA. The quinonemethide triterpenoid also possesses significant inhibitory effects on the growth of synovial fibroblasts, in particular modulating the calcium homeostasis in multidrug-resistant rheumatoid arthritis synovial fibroblasts.

  • Patent number: 10493118
    Abstract: A method for treating a subject suffering from a neurodegenerative disease includes administering at least one triterpenoid which can be obtained from Hedera helix. A method for treating a subject suffering from a neurodegenerative disease includes administering an effective amount of a Hedera helix extract which comprises the triterpenoid. The neurodegenerative disease is preferably but not exclusively Parkinson's disease or Huntington's disease. Methods for extracting the triterpenoid from Hedera helix and a method for inducing autophagy in cells by contacting them with the triterpenoid are also provided. The triterpenoid allows an exceptional induction of autophagy, in particular a significant reduction of the protein level of mutant huntingtin, a significant reduction of the protein level of A53T ?-synuclein, a significant inhibition of the oligomerization of ?-synuclein and a significant inhibition of the inclusion formation of huntingtin via the AMPK-mTOR dependent autophagy inducing pathway.

  • Patent number: 10322097
    Abstract: A quinonemethide triterpenoid is administered to subjects with multidrug-resistant cancer, in particular a cancer with enhanced expression and/or functional activity of ABC transporter proteins such as P-glycoprotein and/or an apoptosis-deficient, in particular p53-, Bax- or Bak-deficient, cancer, i.e. specific subgroups of subjects with cancer. The quinonemethide triterpenoid is suitable to treat cancer allowing for an accumulation of cytotoxic or therapeutic compounds in the cells while having exceptionally increased cytotoxic activity towards the multidrug-resistant cancer cells and while allowing for an increased activity of chemotherapeutic compounds. Methods for specifically targeting cancer cells with multidrug-resistance and methods for potentiating the activity of a chemotherapeutic compound in those cancer cells are also disclosed. A kit including a quinonemethide triterpenoid and a chemotherapeutic compound is also provided.

  • Patent number: 9955676
    Abstract: The present invention provides an in vivo platform for identifying and determining therapeutic or prophylactic activity of test compounds in delay-type hypersensitivity (DTH) and other inflammatory or cancerous diseases mediated by activation of IKK-?C46A mutants. The in vivo platform of the present invention is a non-human transgenic mammal, e.g., a mouse model, with a site directed mutagenesis at a cysteine residue replaced by alanine in IKK-? protein kinase. The site directed mutagenesis is introduced by a specially designed targeting vector containing a transversion in exon 3 of the Ikbkb genes encoding the IKK-?. The present invention also provides methods for generating the transgenic mammal and for determining and identifying compounds that can inhibit activation of IKK-?C46A mutants.
