Developing safer and more effective mTOR inhibitors to treat disease and extend healthy lifespan

Rapamycin was the first therapeutic definitely shown to extend lifespan in mammals

ADD REFERENCE

Rapamycin extended lifespan in mice even when started late in life and when given intermittently.  These findings suggest that rapalogs may be of benefit for treating or preventing aging-related conditions in humans.

A rapalog that inhibits mTOR specifically within the TORC1 complex is predicted to be safer than currently approved rapalogs

ADD REFERENCE

mTOR signals within 2 multiprotein complexes called TORC1 and TORC2. Inhibition of TORC1 upregulates protective pathways, prevents overactive mTOR cell signaling and extends lifespan in multiple species. Inhibition of TORC2 may be important for inhibiting cell proliferation but decreases lifespan and causes adverse events such as hyperglycemia and hyperlipidemia.

mTOR is a protein kinase that has been conserved across billions of years of evolution and links the supply of nutrients to growth and reproduction

When nutrients are abundant, mTOR is activated and stimulates the building blocks that organisms need to grow and reproduce.

When nutrients are scarce, mTOR is inhibited and upregulates stress resistance protective pathways. The stress resistance pathways that are upregulated by mTOR inhibition may also be important for protecting organisms from aging-related deterioration.

Activity of the protein kinase mTOR regulates aging

mTOR inhibition extends lifespan in every species studied to date. The lifespan extending effects of mTOR inhibition have been conserved across a billion years of evolution

Tornado is developing a portfolio of next generation rapalogs that are predicted to have superior safety and/or efficacy to currently approved first generation rapalogs

Currently approved rapalogs inhibit mTOR both within the TORC1 and TORC2 complex. Tornado has in-licensed a portfolio of next generation rapalogs developed by expert chemists at Novartis that includes multiple compounds that are potent TORC1-specific inhibitors. These compounds are predicted to have better safety and efficacy than first generation rapalogs for treating aging-related diseases and extending healthy lifespan.

In addition Tornado’s portfolio of rapalogs includes multiple compounds that are more potent inhibitors of TORC1 and TORC2 as compared to first generation rapalogs and may have superior efficacy as compared to currently approved rapalogs in conditions such autoimmune diseases and cancer.
