The French National chemical library (Chimiothèque Nationale) offers a diverse collection of more 80,000 compounds and 15,000 original  natural extracts. Packaged in a standardized form compatible with high- and medium-throughput screening, these compounds can be solicited in the framework of scientific collaborations, through simple, fast, inexpensive and legally protected procedures by a MTA (MTA_EN_GIS_CBF.pdf). 

The Chimiothèque Nationale also offers competent partners for hit-to-lead developments.

Objectives and missions of the Chimiotheque Nationale: 

The Chimiothèque Nationale (CN) was created in 2003 by the CNRS. In 2007, the CN took the legal form of a Scientific Interest Group (GIS), through an agreement signed by 25 research organizations and higher education establishments. Since 2019, the CN has been one of the 4 pillars of ChemBioFrance Research Infrastructure.

The objectives of the CN are:

- the backup and conservation of the synthesis compounds and natural extracts patrimony existing in french academic laboratories;

- scientific valorization of these collections held by each CN laboratory.

The missions of the CN are:

- to federate the French academic research laboratories wishing to promote the constitution and the scientific and industrial valorization of their collections of compounds and natural substances, in a format compatible with high-throughput screening;

- to create a global database of these collections, more complete and diverse than each of the collections considered separately;

- to promote the compound and natural extracts collections towards chemists and biologists, academic and industrial researchers with a screening perspective.

You are a chemistry laboratory and you wish to become a member of ChemBioFrance?

The Chimiothèque Nationale works as a network of laboratories, in which each team remains responsible for its molecules and substances, and can decide of their distribution. In becoming a member of ChemBioFrance, you will be able to:

To become a member, you will have to : 

To carry out the first 2 points, ChemBioFrance can give you a technical, financial and administrative assistance. The material needs are limited to only a system of storage of samples (bulk or plate), coupled to a computerized management (CN can provide the software).

French Chemical Library (CN - complete collection)

89,242 compounds ( 70 242 in plate) on the July 07th 2024: This collection is available in 96 or 384 well plates at a concentration of 5 mM in DMSO. Distributed volumes are between 2.5 and 300 nL in echo plates.The participation fee starts from 0.30 € HT per well, shipping included.

Project request
Essential Chemical Library (CNE)

The 1040 compounds in this selection reflect the chemical diversity of the complete compound library of the CN. The quality of the compounds was checked in 2018 and all compounds are at least 80% pure. This collection is available in 96 or 384 well plates at a concentration of 5 mM in DMSO. The distributed volumes are between 1 and 3 µL in frozen standard plates. The stability of these compounds in solution in DMSO was also checked. The participation fee to acquire the CNE is 2211 € HT, shipping costs included.

Project request
Custom collections (cherry-picking)

It is possible to select only a subset of the National Chemical Library and to receive it in 96 or 384-well frozen plates. The selection of this subset can be achieved through molecular descriptors accessible online on the CN website or through chemoinformatic tools (analog search, virtual screening, etc ...). The cost contribution depends on the quantity of wells ordered and the packaging selected. From November 4th, 2020, a quote including the cost contribution will be provided following a cherry-picking (For ex., the cost of a microplate of 96 products is about 400€).

To download all structures from CN, please go the page "Access to the database for registered users only". To visualize and analyse data from the Sdfile, you could use DataWarrior (DataWarrior).

Project request
Targeted libraries

The compounds of the library have been annotated according to their belonging to chemical families such as "kinase-like", "GPCR-like", "iPPI-like", etc., in order to facilitate the selection targeted libraries.

Project request
Dose-response plates

It is possible to prepare plates containing concentration ranges, for example to determine dose-response curves. The number of points (~ 10), the concentration range and the volume of the wells have to be defined according to the experimental test. The cost of the wells depends on the quantity of wells ordered.

Fr-PPIChem : A Chemical Library to Target Protein-Protein Interactions

Fr-PPIChem is a chemical library of 10,314 molecules dedicated to the inhibition of proteinprotein interactions (Bosc et al., 2020). These compounds are plated in a standardized form compatible with high or medium throughput screening.

The chemical library is the result of a research program involving 5 academic teams, national platforms and an industrial partner. The members of this consortium have developed two databases dedicated to protein-protein interaction modulators ( and The analysis of these databases has made it possible to define a physicochemical and structural profile characteristic of the inhibitors known to date, by comparing them to drugs or enzyme inhibitors (traditional targets) used in the Western pharmacopoeia.
