But nothing novel novel has every been designed to my knowledge. You have to work backwards here, without knowing at the very least what a receptor binding pocket looks like.
But then also algorithms which optimize the thermodynamics of candidate molecules with the receptor pocket help, to screen out tons upon tons of potential molecules. Basically molecular dynamics but taking into account individual atom affinities and shit, I'm talking way beyond my scope here though
