Longevity Biotech is a leading biotech company developing a new class of therapeutic compounds.
Evolution has developed natural defense mechanisms to combat disease, therefore, many diseases are a result of either an overactive or defective signaling pathway. Longevity Biotech is working to develop specific modulators of these pathways in order to leverage the body’s natural processes.
Drugs fall into two main categories, Small Molecules and Biologics, each with their own benefits and liabilities. Small Molecules are typically taken in pill form and often work generically throughout the body, via simple molecular interactions. In contrast, biologics are typically delivered as frequent injections into patients and are considerably more targeted in their mechanism of action, primarily due to their complex surfaces.
Our Hybridtides® combine the targeting abilities of biologics with the stability of small molecules by building from a breakthrough molecular scaffold discovered in Professor Samuel Gellman’s lab at the University of Wisconsin.
By ‘rebalancing’ the body’s natural circuits, Longevity Biotech is developing new treatments through a completely innovative approach, unattainable without the Hybridtide® scaffold.
Longevity Biotech is currently targeting cell surface receptors that have been identified and validated as key disease pathways. Our Hybridtide® molecules are capable of modulating these pathways, resulting in the desired therapeutic outcome. This class of protein-protein interactions (G-Protein Coupled Receptors, GPCRs) is highly complex and challenging, despite several decades of pharmaceutical interest.
Longevity Biotech is pursuing a new and versatile strategy for creating peptide-like molecules that mimic the information content of specific natural prototype peptides but display superior pharmacokinetic properties relative to conventional peptides. Longevity’s proprietary platform technology promises to provide effective therapeutic and diagnostic agents for a wide range of human diseases. Longevity’s current programs are focused in cardiovascular, metabolic and oncological areas; we are open to partnerships in these and other disease areas.
Longevity’s compounds are created via rational combination of alpha-amino acids, the building blocks of proteins, with carefully chosen unnatural building blocks, to generate Hybridtides®. Properly designed Hybridtides® can recapitulate specific recognition surfaces displayed by natural polypeptides but feature higher metabolic and conformational stability than do conventional peptides. The Longevity approach achieves this desirable profile via internal modifications, which minimize off-target binding behavior and ensuing toxicity. The Hybridtide® strategy is therefore distinguished from other peptidomimetic approaches in which stabilizing or modulating units are appended to the molecular exterior, where they can inadvertently engage unintended biomolecular partners.
The molecular principles underlying Hybridtide® technology were developed at the University of Wisconsin – Madison during many years of fundamental research. Recent successes in proof-of-concept studies led to the founding of Longevity Biotech, Inc., for development of clinically useful Hybridtides® that can inhibit deleterious protein-protein interactions or function as long-lasting agonists at receptors that are naturally modulated by polypeptide ligands. The Hybridtide strategy is particularly promising for targets that are not susceptible to traditional small molecule-based medicinal approaches.
The most mature Hybridtide design pathways involve combination of alpha-amino acid residues with beta-amino acid residues, to generate alpha/beta-peptides. High-resolution structural analysis (academic research) reveals that periodic alpha-to-beta substitution can deliver Hybridtides that very closely mimic alpha-helices from natural polypeptides.

Successful mimicry of the CHR domain of HIV protein gp41 shows that this strategy is effective even for very long helices. In this case, the optimized alpha/beta-peptide blocks infection by clinical strains of the virus in cell-based assays, and this compound displays ~300-fold slower degradation by an aggressive protease relative to an analogous conventional peptide (purely alpha residues).

Dr. Waschek is a Professor of Psychiatry and Biobehavioral Science at the David Geffen School of Medicine at the University of California at Los Angeles (UCLA), and is an expert in the molecular and cellular biology and physiological actions of neuropeptides. Dr. Waschek received a Ph.D. in Pharmaceutical Chemistry in 1984 from the University of California at San Francisco, after which he took a postdoctoral position at the National Institutes of Health (NIH). In 1988 he came to UCLA, where his research has centered on three broad, but related topics: 1) CNS development, degeneration, injury, and repair, 2) neuroinflammatory conditions such as multiple sclerosis, and maternal inflammation-induced perinatal white matter disease, and 3) brain tumor pathogenesis. A past and continuing objective has been to better understand the biological roles of neuropeptides in these processes, especially the two related peptides PACAP and VIP (pituitary adenylyl cyclase activating peptide and vasoactive intestinal peptide, respectively). A major contribution in this area was his discovery first reported in 1998 that PACAP and functional PACAP receptors are highly expressed in the murine neural tube and other germinal centers, and that PACAP acts in part via cAMP and protein kinase A to regulate neural patterning and proliferation via antagonism of hedgehog signaling. Using gene targeting and other approaches, he found this interaction to be relevant not only during brain development, but also in the pathogenesis of malignant pediatric brain tumors. In other work, he has demonstrated growth factor-like actions of PACAP in the maturation of white matter (myelin) and in axon regeneration after injury. Most recently, he determined that VIP and PACAP are critically involved in inflammatory responses after nerve injury and in other pathologies such as lung and liver injury, colitis, cystitis, viral infection, and in an animal model of multiple sclerosis. These studies have revealed significant effects of PACAP and VIP PACAP loss on innate cellular responses to injury, as well as in Th1, Th2, and Th17 differentiation, regulatory T cell production, and immune cell invasion of the CNS parenchyma. Has been continuously funding for his research by the NIH since 1984, and is also currently receiving funding through major grants from the National Multiple Sclerosis Society and the National Brain Tumor Society. Dr. Waschek has served on NIH study sections almost continuously since 2006, and served as an external reviewer for the newly-formed LOWEE Institute on Tumors and Inflammation in Marburg, Germany, and a consultant for the Japanese-Israeli Scientific and Technological Cooperation Agreement in Life Sciences in the Topic of Stem Cell Research

HybridtidesHybridtides® are a new class of therapeutic which incorporate non-natural amino acids. Hybridtides® overcome the challenges of targeting complex protein-protein interfaces for medicinal use. The discreet recognition of these interfaces are crucial in the treatment of many diseases. To date, traditional small molecule approaches have not been able to therapeutically modulate these interfaces due to the extended surface area and complex interactions. The specific non-natural amino acids we use along with the proprietary way in which we use them lead to a dramatic improvement in digestive resistance. The representative data on our targets pages suggest that significantly improved half-lives can be achieved while retaining the necessary biological activity.
Anti-Viral Fusion Inhibitor
Longevity Biotech has licensed a highly effective viral fusion inhibitor Hybridtide® from the University of Wisconsin – Madison. This compound has a vastly superior in-vitro digestive stability when compared to a closely related α-amino acid based fusion inhibitor, while retaining nearly identical activity.
Cardiovascular Disease – Primary Arterial Hypertension (PAH) – Vasoactive Intestinal Peptide
VIP is a highly studied neuropeptide with a variety of function throughout the body. VIP has been implicated as a possible therapeutic mechanism for a number of diseases. The primary function of VIP, when it signals through the VPAC2 receptor, is as a potent vasodilator. In addition, VIP interacts with the immune system as a regulator of the inflammatory response, by upregulating anti-inflammatory cytokines (IL-10 and TGF-β1) while simultaneously down regulating pro-inflammatory cytokines (TNF-α, IFN-γ, IL-1β, and MIP-2). Thus is it no surprise that VIP has also demonstrated beneficial effects in other autoimmune and inflammatory diseases including, chronic obstructive pulmonary disease, arthritis, multiple sclerosis and Parkinsons disease to name a few. Furthermore, as an endocrine system member, VIP has also demonstrated therapeutic benefits in the diabetes world as well, specifically as an anti-hyperglycemic.
Longevity Biotech has identified uniquely selective Hybridtide agonists for the VPAC2 receptor subtype which is responsible for vasodilation as well as anti-inflammatory effects.
Metabolic Syndrome – Dual GLP1 / GIP agonist
The GLP1 mechanism has been well studied for its clinical value in treating Type 2 Diabetes. Recent research however has implicated that a more complex set of interactions can deliver even greater clinical value by dramatically improving on the well-known GLP1 pathway. By developing a novel Hybridtide® candidate that is capable of targeting both GLP1 and GIP simultaneously with a single compound, the delicate balance of activation of these two closely related receptors can be achieved. This pathway, together with the intrinsic benefits of the Hybridtide® molecular scaffold have resulted in a preclinical lead candidate for the treatment of metabolic syndrome, including Type 2 Diabetes. It should be noted that we were able to identify a preclinical lead in significantly less than 50 compounds for this program.
Oncology – Hybridtide Drug Conjugates
Longevity is developing novel approaches to specifically target cancer cells and safely deliver highly toxic payloads. Building on the Hybridtide platform, Longevity has identified a number of cell-surface receptors that are addressable with this strategy along with a library of potent payloads (including novel Hybridtide based warheads). When these receptors are internalized, the payloads deliver their therapeutic dose. Our Hybridtide-Drug-Conjugate (HDC) strategy is similar in concept to commercially available Antibody-Drug-Conjugates (ADC), however the HDC approach has several likely advantages:
- Direct site-specific payload conjugation
- Non-cleavable linker potential**
- Simpler manufacturing and quality control
Longevity is currently in early preclinical development of therapeutic Hybridtides® for oncology. Contact us to learn more.
Neuroscience – Anti-inflammatory Strategy
Longevity has identified a potent anti-inflammatory lead candidate that has demonstrated ability to provide a remarkable amount of neuroprotection in vivo. Initial studies in Parkinson’s Disease models (MPTP) have provided the exciting – yet preliminary – proof of concept results. This program has a dual mode of action.
First, by modulating the immune system (Th1/Th2/Th17 balance) and generating a T regulatory response, this therapeutic program aims to enlist the bodies natural systems to provide a therapeutic effect.
Second, this target appears on both immune cells as well as nerve endings themselves. Thus, this program aims to build upon these exciting results and progress towards human clinical trials.
The following list highlights some of the indications that are under investigation.
- Parkinson’s Disease
- Multiple Sclerosis
- Spinal muscular atrophy
These programs are currently in early preclinical development. Contact us to learn more.
