Additonal Data Sets for BioSolveIT Applications

Chemical Spaces

Chemical Spaces are ultra-large, combinatorial compound collections that can be navigated with BioSolveIT tools like infiniSee.

FastGrow Libraries

FastGrow libraries can be used in SeeSAR or the command-line tool FastGrow to screen millions of conformations within seconds to retrieve the best decorations to complement a binding site.

ReCore Libraries

3D scaffold replacement can be achieved with ReCore, an algorithm implemented into SeeSAR's Inspirator Mode. It screens for shape-similar motifs given a set of vectors to replace.

Additonal Data Sets for BioSolveIT Applications

eXplore Cookbook

The Cookbook features chemical reactions used to generate the trillion-sized eXplore Chemical Space by eMolecules. These are robust reactions that can be performed in most standard laboratories. The included SMIRKS definitions are ideal for setting up your own Chemical Space.

More Data Sets

13 drug candidates first mentioned at the EFMC-ISMC and ACS Fall Meeting were analyzed in infiniSee xREAL using all three modes to identify the closest matches to these advanced designed molecules.
An infiniSee search was conducted for approved drugs and advanced candidates. All three modes were utilized, and the available Chemical Spaces were explored.

Structure-Based Drug Design (SBDD)

Structure-based drug design (SBDD) features methods that are applied on a 3D representation of the target structure.
This PDF describes how computational tools can be used to predict promising drug candidates by discovering structurally novel motifs or by improving the properties of known binders.

Ligand-Based Drug Design (LBDD)

Ligand-based drug design (LBDD) aims to predict novel hits or improved compounds without the need of information on a target's structure or even the particular drug target itself.
Several approaches exists to come up with solutions for different scenarios. Most of them start with a single known binder or a set of them to come up with structurally-related compounds to follow up with.

Fragment-Based Drug Design (FBDD)

Fragment-based drug design (FBDD) utilizes (very) small molecules as starting points for compound evolution campaigns.
By introducing additional interactions with the target structure by decorating the fragment with functionalities, or by connecting or merging it with other fragments or compounds, potency of the compound is improved until it reaches desired properties.

Further Resources on Chemical Spaces

Chemical Spaces are ultra-large, combinatorial collections of compounds that behave differently from traditional enumerated molecule libraries. In this post, we highlighted the differences and explained why Chemical Spaces are an ideal resource for drug discovery, using a metaphor involving burgers to illustrate their advantages.
Chemical Space Docking™ is a novel, structure-based method to mine for promising drug candidates displaying favorable interactions within a target's binding site. This virtual screening method can efficiently search in billion- or even trillion-sized Chemical Space for the most relevant results.
Compared to standard methods, it accelerates the whole workflow using a smart combinatorial approach.
In this post, we explored how Chemical Space exploration can be conducted. Several interesting publications were highlighted, showcasing both the possibilities and limitations of this approach.
There are various ways to navigate Chemical Space. The most challenging aspect is that similarity is a highly flexible concept, and it often takes time to understand what exactly you are looking for. Therefore, different methods can be employed to discover interesting compounds.
For the data enthusiasts, we’ve made a direct comparison between combinatorial and enumerated approaches, converting the data sizes into a potato-based unit for fun.
Do you need multiple Chemical Spaces? Intuition suggests they should share a large number of molecules. However, intuition can be deceiving.
Although Chemical Space technology has advanced significantly in recent years, the core messages of the white paper remain as true as ever: Chemical Spaces are the ultimate hunting grounds for the early stages of drug discovery.
Ever wondered how Enamine manages to offer such a vast number of compounds at competitive prices? We have broken down the journey from concept to doorstep delivery.

Further Resources on Molecular Modeling

It is not always easy to pick the right compounds. We have collected insights on how to implement molecule evolution in a sophisticated way into your workflows using BioSolveIT applications.
This write-up will help you understand the basics of docking and where to pay attention to details to achieve scientifically sound results.
The idea to replace an undesired motif in a molecule may have many reasons. This scaffold hopping approach aims to identify somewhat similar compounds to a query while maintaining the key features for proper interaction with the target.
Fragments are the smallest molecules that form high-quality interactions with their target. By adding additional functionalities, their potency is increased until they reach the stage of a full-fledged drug candidate.
Peptide design is one of the more resource-intensive methods in computational drug design. However, with the FastGrow tool and SeeSAR feature, one can quickly generate metabolically more stable compounds that effectively interact with the binding site.
