Molecular Discovery is a company founded in 1983 in the UK that develops computational tools to help with drug discovery projects. They have over 20 employees including chemists, biologists, and programmers. Some of their main products are virtual screening tools, structural based design tools, descriptor calculation and modeling software, and tools for metabolism prediction. Recently, they have been working to combine experimental mass spectrometry data with their in silico prediction tools to better inform medicinal chemists and allow collaboration through a web-based system called WebMetabase.
