"In my opinion, software of this sort belongs on the desktop of any chemist designing bioactive molecules."
John van Drie in JACS 131 (2009) 1617 |
|
"ReCore works well! It has a user-friendly interface, and the constraints are easy to set up."
GSK, China. |
|
"The diversity of solutions from ReCore is much better than similar types of software."
Roberto Forlani, NiKem Research Srl, Italy. |
|
| scientific background |
|
ReCore replaces a given core: Given a pre-defined central unit of a molecule (the core), fragments are searched in a 3D database for the best possible replacement – whilst keeping all connected residues, i.e., the rest of the query compound in place. Additionally, user-defined "pharmacophore" constraints can be employed to restrict solutions. |
|
 A typical workflow is a two stage process, of which Stage A needs to be performed only once (click picture for further information). |

| download |
Please note that ReCore requires a 3D fragment space to search in. The evaluation copy comes with a sample space.
You can certainly only find scaffolds which are in the search space.
Therefore, we recommend you create your own in-house space based on 3D ligand datasets such as the CSD.
ReCore is now part of LeadIT (follow this link for the download). The stand alone version is no longer supported.
