Lassogen, Inc. is a start-up biotechnology company in San Diego that currently is operating in stealth mode.


Lassogen’s mission is to unlock the full potential of lasso peptides as a new therapeutic modality for diagnosing and treating challenging diseases, including multi-drug resistant bacterial infections and cancer.


Lasso peptides are naturally produced by bacteria and represent a unique, vast, untapped source of novel molecular diversity for drug discovery and development.  The distinctive lasso fold and 3D topology of lasso peptides engender these systems with beneficial properties (protease, low pH, heat stability) and potent biological activity against challenging drug-resistant Gram-positive, Gram-negative and mycobacterial pathogens, as well as difficult targets such as G protein-coupled receptors for cancer immunotherapy applications. Lassogen’s cutting-edge platform, which integrates genomics, advanced synthetic biology tools, and data analytics, enables high throughput production and optimization of our innovative lasso-based therapeutics.  We look forward to sharing more as Lassogen advances - stay tuned.


Lassogen is actively exploring investment and business partnerships to launch this exciting opportunity.  If you are interested in learning more about Lassogen, please send inquiries to:
