Silicos NV is pleased to announce the release of its open source online application tool called ProfiLIB, built on top of the Open Babel 2.3.0 C++ library and incorporating many of Silicos' open source programs. ProfiLIB is an online application tool that can be accessed from the Silicos website without any charges [http://www.silicos.com]. An example report is also available from this website.

The profiLIB tool generates in an automated fashion a full report of the molecular characteristics of a user-provided compound library. The first part of the analysis is made in terms of molecular descriptors and physico-chemical properties. These properties are compared to Silicos' in-house vendor compound library Simosa™ to position the input set in relation to an average sample of these vendor compounds. Secondly, the library is mapped onto the vendor chemical space using Silicos' open source Spectrophores™. This mapping is overlaid with a set of diverse compound classes linked to specific drug targets. In the third and final part of the analysis, the library is characterized in terms of the molecular scaffolds represented by the set. Two distinct scaffold sets are statistically compared with the scaffolds from the vendor compounds from Simosa™.

Silicos NV is a Belgian service-based company providing services and tools in the fields of chemoinformatics, chemogenomics and database characterisation. Several other chemoinformatics tools have been brought into the open source domain by Silicos, including SIEVE, PHARAO, PIRAMID, and OBSPECTROPHORE, the latter being part of Open Babel 2.3.
