  • Publication number: 20180085413
    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.

  • Publication number: 20180050044
    Abstract: A method for treating a subject suffering from a cancer, in particular a multidrug-resistant cancer includes administrating a cobalt-polypyridyl complex to the subject. A method for suppressing the growth of cancer cells, in particular inducing autophagy of the cancer cells, inducing cell cycle arrest of the cancer cells and/or inhibiting cell invasion of the cancer cells and for specifically targeting cancer cells with multidrug-resistance includes contacting said cancer cells with the cobalt-polypyridyl complex. A pharmaceutical composition and a kit are provided and include the cobalt-polypyridyl complex. Unexpectedly, the cobalt-polypyridyl complex is especially suitable to treat cancer, in particular multidrug-resistant cancer with an exceptionally increased cytotoxic activity towards multidrug-resistant cancer cells.

  • Patent number: 9861623
    Abstract: The present invention provides methods for treatment of a RAS-positive disease, in particular KRAS-positive non-small cell lung cancer as well as a method for potentiating the apoptotic activity of a PDE? inhibitor by combining the PDE? inhibitor with a direct autophagy inhibitor. The PDE? inhibitor is preferably, but not exclusively, deltarasin, and the direct autophagy inhibitor is in particular 3-methyladenine. Further provided by the present invention are a kit and a pharmaceutical composition comprising the PDE? inhibitor and a direct autophagy inhibitor. The methods of the present invention in particular provide a new treatment option for RAS-positive diseases such as KRAS-positive non-small cell lung cancer allowing for an increased apoptotic activity of the PDE? inhibitor by simultaneously blocking its “tumor protective” autophagy.
