Existing drugs have the potential to be repurposed for new therapies using a computational proteochemometric method called “train, match, fit, streamline” (TMFS). The present method takes advantage of the known structure of a drug molecule, and matches them to known structural targets of human proteins within a database to use as potential new therapies.
New interactions could lead to potential new therapies using existing drugs.
• Existing medications used for new therapies do not need retesting to indicate safety, thus saving drug companies time and money
• The TMFS method will be able to match drugs to their targets more efficiently
• In a recent study, the TMFS method predicted drug-target associations with a 91% accuracy
• The TMFS method discovered that mebendazole has the structural potential to inhibit VEGFR2
• The TMFS method predicted that dimethyl celecoxib can bind cadherin-11. This was later confirmed with surface plasmon resonance.
Stage of Development
The TMFS method has been used to profile 3671 FDA approved/experimental drugs against 2335 human protein targets. A number of drug-target associations that have potential new disease applications have been predicted.
