FTrees 3. Now parallelized, much improved, and on the Mac.

Our FTrees Fuzzy Similarities are now available in an almost entirely re-written version that runs better and much faster. It uses all your CPUs, has an improved chemistry model behind, for example realizing different tautomers as multiple faces of the same molecule. Also you can use it in a single line with an infinitely large number of molecules in your input file. Oh, and it creates beautiful graphics of your matches, so that we can all understand WHY two molecules are seen similar or not — and the best of it all: It runs on a Mac.
Get it!

new SeeSAR v5.1 hops scaffolds: the first ReCore functions are online!

  • ReCore Instant Rescaffolding — early integration
    Many of you will already know our award winning software ReCore. This release includes a sneak preview of the upcoming ReCore integration into SeeSAR. As this is only a preview release, you will need to carry out a few steps of preparation to discover its benefits: Ludicrously fast proposals from gigantic fragment libraries.
  • Now it is simple to rename your molecules
    Double-click on the molecule to type in a new name — this is particularly useful for putting names to results of your molecule editing.
  • Access your files and download history more easily with the centralized loader
  • Molecule annotation now only one click away
    The molecule annotation is now directly accessible with one click on the triangle mark to the left of the table rows. Mouse-over shows you your annotations while a click opens a small editor to edit them.

webinar: Bruton’s Tyrosine Kinase – the story of two inhibitors

Our June webinar will be touching on two recently published stories on Btk: one by Takeda and one by Genentech. Both came up with different strategies to develop a lower molecule weight inhibitor than ibrutinib. We will showcase both strategies in SeeSAR and show how SeeSAR can be used to come up with the right compound.

The registration for the webinar is now open!

BioSolveIT announces the 3 winners of the Winter Challenge’s phase 1

The 3 winners of our Winter 2015’s phase 1 (first 3 months) have been determined, and believe us, it was a hard decision! All contestants had great results and compelling summaries, and it was really hard to find the little differences that in the end determined who advanced to the next phase: the following 9 months. Our winners who advance to the next phase are:
  1. Maria Letizia Barecca: Identification of pharmacological chaperones for cellular prion protein
  2. Graeme Rogers: Is there an allosteric site in TCTS?
  3. Andrea Astolfi: Structure-Based optimization of a new chemical scaffold acting as p38α MAPK inhibitor
In the next 9 months these 3 will battle over the final title and a travel grant of €1,000 to a high impact conference. We will report on the challenge site ( about each of their topics in more details. Watch this space!

„JournĂ©e de ModĂ©lisation pour tous“ in Toulouse, France (in French)

BioSolveIT vous invite à une journée "Modélisation pour tous chimistes" à Toulouse en Avril/Mai 

Ce workshop s'adresse à tous ceux qui cherchent des nouvelles molécules thérapeutiques.

Avec le logiciel SeeSAR (site web SeeSAR), qui représente une interface graphique dédiée à l’optimisation visuelle de l’interaction ligand-récepteur, on apprendra les notions de base de la modélisation "structure-based": docking et scoring, analyse conformationelle etc.

SeeSAR, conçu pour être facile à utiliser, permet le calcul de propriétés physico-chimiques, d’affinité, et facilite les modifications de la molécule afin d’utiliser au mieux l’espace disponible au sein du site de liaison. Vous trouverez plus de détails sur le site dont l'adresse est mentionné ci-dessus.

La rencontre aura lieu sur Toulouse pendant une journée: une matinée d'introduction et présentation, suivie (optionnellement, pour ceux qui souhaitent y participer) par un entrainement pratique, avec la distribution de licences gratuites personnelles de 6 mois - exclusivement pour les adhérents SCT (Société de Chimie Thérapeutique).

Si vous êtes intéressé(e)s, veuillez marquer vos préférences concernant les dates (et la participation dans l’entrainement) dans le questionnaire Foodle à l’adresse suivante:

Je participe! (questionnaire Foodle)

Pour pouvoir joindre le maximum des personnes potentiellement intéressées par l’utilisation de visualisation et modélisation, on vous demande d’avoir la gentillesse de transmettre ce message à vos collègues chimistes médicinaux et modélisateurs.
