PepLib is rethinking peptide drug discovery: a revolutionary platform technology company with a proprietary peptide library, unique screening capabilities, and robust internal drug development programs. PepLib’s novel peptide technology platform uses cyclic peptides to encode and compress half of a billion sequences, including complete peptide libraries up to pentapeptides (ZSenithFive™). PepLib’s platform, powered by Peptide Information Compression Technology (PICT), is capable of high-sensitivity and high-specificity drug mining for a broad spectrum of targets, including membrane-proteins. Intelligently designed, individually isolated and packed peptides in HTS well format support functional assays, including cell-based assay and in vivo assay. PepLib has validated the efficiency of the platform on the well-studied PD-1/PD-L1 model and through their partnerships with multiple pharmaceutical companies and internal development programs in oncology, pain, metabolic disorders, and antimicrobials/antivirals, including COVID. Formed by leading scientists in peptide chemistry and biosynthesis with a combined 75 years of biopharmaceutical R&D experience, PepLib hopes to leverage its innovative platform to advance peptide drug discovery for the global biopharmaceutical community.
