The present invention relates to tetraaza phenalen-3-one compounds which inhibit poly(ADP-ribose) polymerase (PARP) and are useful in the chemosensitization of cancer therapeutics. The induction of peripheral neuropathy is a common side-effect of many of the conventional and newer chemotherapies. The present invention further provides means to reliably prevent or cure chemotherapy-induced neuropathy. The invention also relates to the use of the disclosed PARP inhibitor compounds in enhancing the efficacy of chemotherapeutic agents such as temozolomide. The invention also relates to the use of the disclosed PARP inhibitor compounds to radiosensitize tumor cells to ionizing radiation. The invention also relates to the use of the disclosed PARP inhibitor compounds for treatment of cancers with DNA repair defects.

The invention also relates to the use of the disclosed PARP inhibitor compounds to radiosensitize tumor cells to ionizing radiation. The invention also relates to the use of the disclosed PARP inhibitor compounds for treatment of cancers with DNA repair defects.

The invention relates to non-peptidic compounds that possess bioactive properties, such as the ability to protect neuronal cells from otherwise lethal treatments or the ability to promote the growth or regeneration of neuronal cells. In part, the invention provides compounds that interact with or bind to a cyclophilin and compounds that have activity towards neuronal cells. Methods for using the compounds, such as administering them to cells or animals or using them to treat neurodegenerative conditions, are specifically included.

Non-peptidic cyclophilin binding compounds and their use

The present invention relates to novel, non-peptidic small organic compounds having an affinity for cyclophilin (CyP)-type immunophilin proteins, and to pharmaceutical compositions comprising one or more of the said compounds. The invention further relates to the uses of these compounds and compositions for binding CyP-type proteins, inhibiting their peptidyl-prolyl isomerase activity, and for research, development, and therapeutic applications in a variety of medical disorders.
