Definitions
- the present invention relates to a novel pharmaceutical use of a compound having an AMPA receptor antagonistic activity as a therapeutic agent for glioblastoma.
- Darioma is a generic term for tumors that grew during the process of differentiation from glioblasts, the glia stem cells, to ependymal cells, astroglia, and oligodendroglia. (Biochemical Dictionary 3rd edition Tokyo Chemical Dojin, Tokyo , 1998).
- Glioblastomas are the most widespread, highly aggressive, and typical malignant brain tumors in the central nervous system among gliomas.
- the fatality rate is extremely high, and death occurs 9 to 12 months after onset. Even today, with the development of various treatments, the 5-year survival rate (8.0%) between 1986 and 1990 was still lower than the 5-year survival rate (11.9%) from 1969 to 1975, 20 years ago. With little change (Neural Advancement 43 (3), 338-350, 1999), the establishment of effective treatments is eagerly awaited.
- Glioblastoma cancer cells are the most undifferentiated type of brain tumors, have high migration and proliferative properties, have high invasiveness, and have an extremely poor prognosis.
- Glioblastomas are caused by differences in the genetic mechanism of malignancy from undifferentiated stellate cells or progenitor cells, and primary glioblastomas and primary glioblastomas Secondary glioblastoma). Secondary glioblastomas occur in young people under the age of 45 and develop through anaplastic astrocytomas within an average of 4 to 5 years after astrocytoma. Primary glioblastomas, on the other hand, occur more frequently in the older age group, averaging 55 years of age, and are usually fulminant types that develop within three months from no clinical or pathological abnormalities. Glioblastoma (also called de novo glioblastoma) iPatholoay and Genetics of the Nervous Systems. 29-39 (I ARC Press, Lyon, France, 2000).
- glioblastoma migrates along the myelinated nerve and spreads extensively in the central nervous system, Chir. (Tokyo) 34, 91-94, 1994, Neurol. Med. Chir. (Tokyo) 33 425-428, 1993, Neuropathology 17, 186- 188, 1997). In Japan, glioblastoma has only a limited number of drugs, such as ranimustine and interface, and its efficacy is insufficient.
- ⁇ -Amino-3-hydroxy-5-methyl-4-isoxazolylpropionic acid ( ⁇ ) type glutamate receptor is one of the ionic glutamate receptors, and is a central nervous system of almost all excitatory synapses. It is responsible for rapid neurotransmission (Trends Neurosci. 16, 359-365, 1993, Annu. Rev. Neurosc 17, 31-108, 1994, Prog. Neurobiol. 54, 581-618, 1998).
- the AMPA receptor is expressed on many glial cells as well as on neurons (Trends Pharmacol. Sci. 21, 252-258, 2000).
- the AMPA receptor consists of four subunits, GluR1-4.
- the Ca2 + permeability of the AMPA receptor depends on subunit organization.
- receptors with GluR2 subunits, C a 2 + permeability is low, the receptor having no GIUR2 has a high C a 2 + permeability.
- the more GluR2 subunits, the lower the Ca 2+ permeability (Trends Neurosci. 16, 359-365, 1993, Annu. Rev. Neurosc 17, 17, 31-108, 1994, Prog. Neurobiol. 54, 581- 618, 1998).
- GluR2 a unique property of GluR2 is that when one amino acid residue of the second hydrophobic part (M2), usually arginine (R), is replaced with glutamine (Q), a homomer composed of the substituted GluR2 (Q) receptor shows a high C a 2 + permeability (Trends Neurosci. 16, 359-365, 1993, Annu. Rev. Neurosci. 17, 31 -108, 1994) it is Ru mentioned. That is, even if the number of GluR2 subunits is large, the GluR (Q) type subunit shows high Ca 2+ permeability, but the GluR2 (R) type does not show Ca 2+ permeability.
- M2 second hydrophobic part
- R usually arginine
- Q glutamine
- C6-glioma has low expression of the GluR2 gene ( ⁇ Nuerosci. Res. 46, 164-178, 1996), and 66% of glioblastoma cultured cells receive glutamate. It has been reported that it depolarizes in response to body agonists (Eu ⁇ Neurosci. 10, 2153-2162, 1998).
- Patent Document 1 discloses an invention relating to a method for inhibiting the interaction between an AMPA receptor complex and glutamate for treating cancer, and as a specific example of brain tumor, medulloblastoma classified as fetal tumor ( medulloblastoma), a brain astrocytoma that is a type of dario astrocytoma) have been shown to demonstrate the in vitro effects of the AMPA receptor antagonist GYK 2446 on cerebral astrocytomas.
- Non-Patent Document 1 by the above-mentioned inventor states that NMDA and AMPA receptor antagonists are highly sensitive to cancer cells derived from the periphery, but are less sensitive to cancer cells derived from nerves and Darya cells. There is a description. Furthermore, it is described that these antagonists are useful as therapeutic agents for peripheral cancer. Therefore, the effect of the present invention on glioblastoma cannot be predicted from the in vitro effect using cancer cells of lower malignancy than glioblastoma.
- Non-Patent Document 2 reports that MK-801 and memantin, which are NMDA receptor antagonists, exhibited a growth inhibitory effect on rat C6 and RG2glioma transplant models.
- Non-Patent Document 4 which is a critique of Non-Patent Document 1, suggests that AMPA receptor and NMDA receptor may be inhibited as one of multiple treatment methods for glioma. ing. However, the authors have also questioned whether the animal model using C6 and RG2glioma used in Non-Patent Document 1 reflects human cancer.
