The number of clinical trials is based on search results for all listed trials, completed, active, or planned, found on www.clinicaltrials.gov (accessed July 7th, 2020). For the route networks, the yellow dot at the center is the target molecule. Routes in grey and orange below the target are published, and the routes in purple and pink above the target are routes predicted. Intersection nodes in literature routes reflect common intermediates or starting materials. A version of this diagram is available as an interactive route visualizer.
