About Compugen’s GPCR Peptide Library
The more than 900 peptide molecules in Compugen’s GPCR peptide library were predicted through the use of Compugen’s GPCR Peptide Ligand Discovery Platform. The initial validation activities for this platform resulted in the predictive discovery of a number of novel peptides that were subsequently shown to have therapeutic potential in disease animal models of cardiovascular, fibrotic and inflammatory conditions. Further enhancements and extensions during, and subsequent to, the initial validation, have resulted in the current platform, which relies on a series of sequential computational biology models and machine learning capabilities for the prediction and selection of product candidates. The platform incorporates a proprietary model of the “peptidome,” an in silico prediction of putative human peptides, which includes thousands of novel predicted human peptide sequences, based on predicting cleavage sites in precursor proteins. The discovery platform utilizes proprietary machine-learning algorithms to analyze this peptidome and to identify peptides likely to activate GPCRs.
About DiscoveRx’s PathHunter Platform and GPCR related Technologies
DiscoveRx’s innovative approach to GPCR signaling assay development, using a simple, homogeneous, chemiluminescent, read-out based on β-galactosidase-based enzyme fragment complementation (EFC), is core to the success of many drug discovery programs. The emerging field of GPCR drug discovery is necessitating the analysis of GPCRs using multiple assay approaches. From the traditional second messenger signaling assays to the novel, universal β-arrestin recruitment assays for known and orphan GPCRs to the next generation platforms for studying GPCR internalisation and heterodimerisation, DiscoveRx is addressing current and emerging drug discovery needs through innovative GPCR assays and profiling services and by offering more than one signaling assay platform for a single GPCR target ( www.discoverx.com/gpcrs).About Compugen Compugen is a leading therapeutic product candidate discovery company, currently focused on biologics-based therapy to address important unmet needs in the fields of immunology and oncology, either for Compugen or its partners. Unlike traditional high throughput trial and error experimental based drug candidate discovery, Compugen’s discovery efforts are based on systematic and continuously improving in silico (by computer) product candidate prediction and selection followed by experimental validation, with selected product candidates being advanced in its Pipeline Program to the pre-IND stage. Compugen’s in silico predictive models utilize a broad and continuously growing infrastructure of proprietary scientific understandings and predictive platforms, algorithms, machine learning systems and other computational biology capabilities. The Company’s business model primarily involves collaborations covering the further development and commercialization of Compugen-discovered product candidates and various forms of “discovery on demand” arrangements, in both cases providing Compugen with potential milestone payments and royalties on product sales or other forms of revenue sharing. In 2002, Compugen established an affiliate, Evogene Ltd. ( www.evogene.com) ( TASE: EVGN.TA), to utilize certain of the Company's in silico predictive discovery capabilities in agricultural biotechnology.
