Longevity Biotech is developing a new class of therapeutic candidates called Hybridtides®. Our focus is on delivering clinically transformative products that tackle the most challenging aspects of medicine today. The unique Hybridtide® scaffold provides critical enhancements over previous peptide development efforts. Contact us to learn more.
Hybridtides® are synthetic peptides based on the seminal work by Prof. Samuel Gellman at the University of Wisconsin. Hybridtides® provide a unique peptidomimetic scaffold that is both digestively and structurally stable. This stability arises from the proper incorporation of α and β amino acids, a process in which we are experts. A variety of peptide engineering opportunities are derivative from this fundamental scaffold.
Building on the Hybridtide® scaffold, Longevity Biotech has created a streamlined, high throughput, data-driven process to deliver peptides orally. Once the requisite digestive stability via the Hybridtide® Optimization Toolkit (HOT®) Hybridtides ® are evaluated and optimized for absorption via the Oral Peptide Platform (OPP). Finally, the resulting lead candidate is evaluated in vivo for absolute bioavailability.
To date, Longevity Biotech has applied the Hybridtide® scaffold primarily to the class B-GPCR family of drug targets - with great success. Currently, our Hybridtide® based neuroscience and diabetes programs target receptors in this family. These assets are in preclinical development along with several other projects as well. If there is any interest in learning more about these programs please contact us to learn more

Dr. DeGrado is a prominent researcher working in the area of chemical biology, biochemistry, and biophysics at the University of California, San Francisco medical school. Prior to his current position, he spent 10 years at the University of Pennsylvania and 15 years at DuPont and DuPont-Merck Pharmaceuticals, reaching the level of Senior Director of Medicinal Chemistry before moving to academics in 1996. Dr. DeGrado has earned numerous awards, including membership in the National Academy of Sciences, and the American Association for the Advancement of Science, and he has been an adjunct faculty member at Harvard University and Johns Hopkins Medical Schools. He is a recent President of the Protein Society, has served on the Editorial Boards of 19 scientific journals, and has authored over 200 publications and multiple issued U.S. patents. Dr. DeGrado is the founder of PolyMedix (PYMX.OB) as well as InfluMedix, and has been on the scientific advisory boards for Xencor, Sunesis, and ExSAR. He holds a Ph.D. in Chemistry from the University of Chicago, and B.S. from Kalamazoo College
Dr. Howard E. Gendelman is the Margaret R. Larson Professor of Internal Medicine and Infectious Diseases, Chairman of the Department of Pharmacology and Experimental Neuroscience, and Director of the Center for Neurodegenerative Disorders at the University of Nebraska Medical Center. Dr. Gendelman is credited in unraveling how functional alterations in brain immunity induce metabolic changes and ultimately lead to neural cell damage for a broad range of infectious, metabolic and neurodegenerative disorders. These discoveries have had broad implications in developmental therapeutics aimed at preventing, slowing or reversing neural maladies. He is also credited for the demonstration that AIDS dementia is a reversible metabolic encephalopathy; a finding realized at the University of Nebraska Medical Center. His work has led to novel immunotherapy and nanomedicine strategies for Parkinson’s and viral diseases being tested in early clinical trials as a result of intense translational investigations.
Soumitra S. Ghosh, Ph.D.
Dr. Soumitra Ghosh is a biotechnology industry consultant and entrepreneur with extensive experience in drug discovery and drug development. His biopharmaceutical experience includes R&D leadership positions at Amylin Pharmaceuticals and MitoKor. At these companies, he led multi-disciplinary research teams for the development of small molecule, peptide and protein based drug candidates for the treatment of metabolic diseases and CNS disorders. His other current roles are acting CSO, Avexegen Therapeutics, Inc., Co-Founder and Scientific Advisor, BioShore Partners, Inc., and President of the Peptide Therapeutics Foundation. He received his MS and Ph.D. degrees in Chemistry from the Indian Institute of Technology and the University of Chicago, and conducted his post-doctoral research at Rockefeller University in New York.
Chris A. Rhodes, Ph.D.
Dr. Rhodes founded Drug Delivery Experts in 2014 after 4 years of consulting and 20 years in pharmaceutical, biotechnology, and drug delivery companies, where he held both technical and executive leadership roles. He has extensive experience translating molecular therapeutics, formulation, delivery, and device programs from late stage research into clinical development.
He volunteers as a leadership mentor to start up companies, students, and academic programs, through the San Diego Entrepreneurs Exchange, Connect, the UCSD Von Leibig Center for Entrepreneurship, the UCSD Bioengineering Industrial Advisory Board, and lectures in the Skaggs School of Pharmacy, in addition to serving on the Board of Trustees of the Boulder Peptide Society.
Chris lives in San Diego with his UCLA graduate school classmate, Dr. Sharon Lee Rhodes, and together they enjoy traveling to visit their four children.
Research in my laboratory centers on a class of molecules called neuropeptides – short peptides that classically act in the central and peripheral nervous systems to control a wide variety of behaviors and neurological processes. Much of our efforts have focused on two structurally-related peptides that are widely expressed in neurons, vasoactive intestinal peptide (VIP), and pituitary adenylate cyclase activating peptide (PACAP). These neuropeptides are rather unusual because they function not only as neurotransmitters, regulating processes such as circadian rhythms, cognition, and stress responses, but as pleiotropic growth factors and immunomodulators. We employ gene knockout and viral delivery strategies as primary tools to study the biological functions of these peptides. In our early work, we established roles of VIP and PACAP in several aspects of brain development and neural repair, and more recently, we delineated their actions as modulators of inflammation in models of multiple sclerosis ad primary neurodegenerative diseases such as Parkinsons Disease. Finally, based on recent genetic links of mutations in VIP and PACAP signaling genes to schizophrenia and post-traumatic stress disorder (PTSD), we have begun to study the involvement of these peptides in the neurocircuities underlying adaptive responses to fear and stress. More detailed information is available on the laboratory website.
