This invention identifies a series of compounds which can selectively regulate the kinase activity of IRE1α and IRE1β, which are paralogous enzymes critical for the activation of the unfolded protein response (UPR) and that may have implications in cell-degenerative diseases such as diabetes, cancer, fibrosis, asthma, and retinitis pigmentosa.
The current technology for regulating IRE1α/IRE1β kinase activities are compounds that have poor oral bioavailability, solubility, and physiochemical characteristics. While these compounds are potent and selective, their chemical properties may not allow for an orally administered IRE1α/IRE1β kinase inhibition.
These novel compounds may have the following advantages:
Since activation of the UPR via IRE1α and/or IRE1β kinase promotes key cellular response to endoplasmic reticulum (ER) stress, inhibition of IRE1α/IRE1β activity has critical therapeutic implications in various UPR related and cell-degenerative diseases. However, current compounds for IRE1α/IRE1β inhibition have excellent chemical profiles but lack oral bioavailability. Researchers at the University of California, San Francisco have identified a novel series of compounds for selectively regulating IRE1α or IRE1β activity. These compounds may represent potent, selective and orally bioavailable IRE1α/IRE1β inhibitors.
To develop & commercialize the technology as an effective treatment for cell-degenerative diseases such as such as diabetes, cancer, fibrosis, asthma/COPD, and retinitis pigmentosa
