Protagonist Therapeutics is a biotechnology company pursuing the discovery and development of target oral peptides as well differentiated alternatives to antibodies, and also as new chemical entities (NCEs) against those targets and life threatening diseases for which suitable small molecule and/or biologic options are not available. Peptides typically suffer from limitations of poor proteolytic stability and therefore find scarce therapeutic utility that is largely limited to ‘injectable drugs’. Protagonist’s technology platform is aimed at overcoming these restrictions and expanding the scope of peptide therapeutics to address unmet needs. Specific emphasis is placed on identifying ‘orally stable’ scaffolds and/or engineering oral stability characteristics onto them. The platform has been optimized over the years and involves synergistic integration of rational drug design, diversity oriented computational tools, phage display libraries, recombinant peptide expression, ex vivo oral stability methods, and peptide/medicinal chemistry techniques. This activity has led to the identification of ‘privileged scaffolds’ with favorable oral stability characteristics. Furthermore, the technology platform is well suited both for de novo discovery against a target and optimization around a given chemical starting point.
Carterra, formerly Wasatch Microfluidics, develops high throughput surface plasmon resonance array-based platforms for biomolecular interaction analysis.
Natural molecules or derivatives make up more than half of the current drugs on the market with applications to nearly every disease known to humans. Salicylic acid, morphine, cannabinoids and insulin are a few examples. Our specialty is in producing these, and new targets, using a fast and scalable platform based on engineered microbes.
Groton Biosystems is a Boxborough, MA-based company in the Healthcare, Pharmaceuticals, and Biotech sector.
Founded by Longwood Fund, Pyxis Oncology is building a differentiated portfolio of biologics, including antibody-drug conjugates (ADCs) and immunotherapies, to improve the lives of patients with difficult-to-treat cancers. Pyxis is employing site-specific conjugation technology to develop highly stable ADCs with enhanced therapeutic indexes. Pyxis is also advancing a diverse portfolio of immunotherapies that target broad immune regulators as well as novel immune checkpoints identified through its immuno-oncology and cold tumor discovery efforts.
