Definitions
- the present invention relates to a non-peptide low molecular weight compound that acts as a factor that determines cell fate.
- the compound acts on the transmission system with STAT signal and Notch signal by decreasing STAT3 phosphate and suppressing Notchl receptor expression.
- the compound acts as an agent for inducing differentiation of undifferentiated cells (stem cells). Due to these characteristics, the compound is useful as a prophylactic / therapeutic agent for pathological conditions induced by dysfunction of both STAT signal and Notch signaling system.
- Notch signaling is a mechanism that is related to cell fate decisions in the developmental and adult phases and does not change much (Non-patent Document 1). Notch signaling is involved in cell fate decisions in many tissues. Notch functions between adjacent cells that have the same function.
- Notch signaling actively promotes the differentiation of various cell types.
- the Notch signal in the nervous system promotes distribution to the first mouth site.
- Notch signals were first confirmed in Drosophila and then in vertebrates. This depends on the transmembrane receptor encoded by the Notch gene (Non-Patent Documents 1 to 3), which is activated by a transmembrane ligand (encoded by a gene such as Delta or agged). Is done. This activation control regulates the proteolytic cleavage of Notch and the transcription of the fragments present in the molecule that bind to the CBF protein, which together activate the transcription of the HES gene. works as a transcription complex. And since HES inhibits transcription of the pro-euron gene MASH1, the activation of Notch in the cell causes the neural stem cells to differentiate into neurons. prevent.
- Notch signaling dysfunction leads to various diseases such as tumors, cancers, neurodegenerative diseases such as Arnno's disease (Non-Patent Documents 2 to 3).
- Cell fate determinants that act on Notch signaling systems have become targets for new drugs.
- Strategies used to date target factors downstream of the Notch signaling system (eg, suppress ligand binding, inhibit receptor proteolytic cleavage, and repress its transcription to the nucleus. Therefore, none of them was able to suppress the expression of Notch.

- Cyclohexenone long-chain alcohols have been previously reported to have neurotrophic effects that promote neuronal survival and neurite outgrowth (Gonzales de Ag uilar et al., Brain Res (2001) 920, 65-73).
- the present inventors have demonstrated in a test using neurospheres that the compound suppresses the differentiation of neural stem cells into astrocytes and promotes differentiation into neural cells (PC T: WO 02/29014 A2).
- STAT3 is activated by being phosphorylated by a large amount of cytodynamic ins (growth factors and hormones). To date, seven STAT families have been identified, some of which can be activated quite specifically. The biological role of STAT3 has been elucidated by studies with knockout mice and Cre-LoxP recombination, and STAT3 plays an important role in various biological functions such as cell proliferation, inhibition of apoptosis, and cell motility. It shows that it plays an important role. On the other hand, the action of STAT 3 on ES (embryonic stem cells) cells suppressed self-proliferation of ES cells and promoted differentiation. Inhibition of STAT3 signaling has been correlated with many cancer cell lines such as blood cancer, breast cancer, head cancer, and cervical cancer (reviewed in Bromber g and Darnell Oncogene (2000) 19, 2468-2473).
