BioSolvetIT infiniSee v4.3.0

infiniSee is a virtual screening platform. Based on similarity, it finds molecules of interest in chemical spaces of (almost) infinite size. Given a template or query molecule, infiniSee returns similar molecules from these chemical spaces — or from screening libraries.


With infiniSee you can finally compare apples and oranges. The underlying concept of infiniSee is strikingly easy: Instead of searching already "assembled” molecules, we instead perform a combinatorial build-up of compounds from "fragments”. Sources of fragments can be either combinatorial libraries or any fragment-generating procedure. infiniSee opens the possibility to screen billions of compounds through its similarity search technology by navigating vast Chemical Spaces and searching for distant neighbors of a query molecule. Results will be delivered within typically less than a minute on a standard laptop. Optionally, you can define fuzzy pharmacophores to increase the diversity of scaffolds or request important molecular structures to be present in the hits.

The ingenious twist of infiniSee is the possibility of searching not only in colossal Chemical Spaces, but the ability to also comb through spaces of different origins. The number of identical structures in sets from different spaces was found to be extremely low (Lessel et al. 2019) due to the design and setup of the spaces, as well as the diversity of the employed building blocks. No matter how big your in-house library and no matter how many compounds you acquire to add to it, it will only be a tiny fraction of what your chemists are capable of synthesizing. Involving distinct Chemical Spaces increases your chances of finding accessible molecules you would have missed otherwise.

Sometimes the perfect solution is within reach in your own compound library without realization. You can design your own Chemical Space with your accumulated, in-house knowledge and resources. Reactions and building blocks can be defined to create massive numbers of virtual compounds. Multiple big pharma companies built their own, in-house Chemical Spaces to search for scaffold alternatives to reduce costs and time.
