Insulin Receptor Antagonists For Treating Hyperinsulinism

Abstract

The area of insulin receptor (IR) antagonism represents a significant but largely untapped research field with a promising potential for advancing our understanding of insulin signaling, and consequently, driving the development of innovative therapeutic strategies for metabolic disorders. Despite the numerous studies on insulin analogs with agonistic properties—owing to their critical role in diabetes treatment—the investigations into IR antagonists are sparse. Our recent discovery of an antagonistic insulin derivative represents a promising starting point for developing new IR antagonists using structure-based designs. Using this strategy, we have been able to identify potent IR antagonists, which have been demonstrated to restore normoglycemia in disease models of hyperinsulinism.

A High-diversity mRNA-platform for the Discovery of Multicyclic Peptides

The identification of selective, high-affinity ligands for membrane receptors and other protein targets is a critical step in the development of novel therapeutics. For small-molecule drug discovery, high-throughput screening (HTS) enables the rapid evaluation of 10⁵–10⁶ compounds per day through automated platforms. In contrast, for biologics such as peptides, proteins, and nucleic acids, selection technologies like phage, mRNA, ribosome, and yeast display offer significantly higher diversity, routinely screening libraries ranging from 10⁹ to 10¹³ variants. By implementing smart selection and deselection strategies, ligands with affinities in the low nanomolar range can often be identified.
Previously, we developed a synthetic strategy for the generation of multicyclic peptides [2]. We have now integrated this platform with mRNA display to enable the discovery of bioactive multicyclic peptides. In this presentation, we share initial findings on potent and selective multicyclic peptide binders targeting Frizzled-5 (FZD-5) and an anti-CCR7 monoclonal antibody, with affinities in the double-digit nanomolar range. Control experiments highlight the critical role of each individual peptide loop in target engagement. Furthermore, the multicyclic peptides exhibit markedly enhanced proteolytic stability compared to their linear or monocyclic counterparts. Together, these results demonstrate the readiness of this multicyclic peptide platform for broader application in the discovery of next-generation peptide therapeutics.

Abstract

The discovery of active peptides, such as antimicrobial, antiviral, catalytic, or self-assembling is challenging, due to the vast search space and limited understanding of how peptide sequences correlate with desired activities and/or functions. The exponential growth of the peptide permutation space with increasing sequence length makes it difficult to explore all possibilities efficiently. To avoid expensive and time-consuming guesswork and experimental failure, we combine machine learning (ML)-based
predictions with genetic algorithm-based optimizations to accelerate peptide discovery. ML can find patterns or regularities in data, build mathematical models based on the theory of statistics and make up for the lack of knowledge.

We curated a dataset of experimentally validated self-assembling peptides and combined aggregation propensity data from molecular dynamics (MD) simulations with a sequential properties representation scheme to train a neural network classifier able to identify peptides with self-assembly propensity. The ML classifier achieved 81.9% accuracy, outperforming the current state-of-the-art models. Furthermore, we developed a flexible and adaptive generative model based on the ML-driven genetic algorithm that allows for a directed search of the sequence space by promoting self-assembly propensity. This enabled the discovery of sequences in unexplored regions of the peptide space, with low similarity to the dataset, which were validated using MD simulations and experiments [1]. This approach not only improves the efficiency of the search but also contributes new knowledge to expand existing peptide datasets, driving future advancements in the field.

A Kiss to Remember

Abstract

KISS1 encodes a 145 amino acid peptide that is processed into various C-terminal fragments, all of which bind and activate its G protein coupled receptor KISS1R (formerly known as GPR54). KISS1R signaling has a fundamental role in the physiology of the reproductive axis and is required for pulsatile secretion of gonadotropin hormone releasing hormone (GnRH) as well as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) at puberty. The kisspeptin system is also present in organs outside the reproductive tract including the liver and bone. This presentation will review the discovery of the kisspeptin signaling system, its C terminal fragments, as well as diagnostic and therapeutic applications.

Clinical Development of a PSD-95 Inhibitor for Acute Ischemic Stroke

Abstract

NoNO Inc. is developing emergency stroke treatments and has demonstrated clinical proof of concept for the in-hospital use of the eicosapeptide nerinetide to improve outcomes for acute ischemic stroke (AIS) patients. Even with the best currently available treatments, at 3 months post-stroke approximately 15% of acute ischemic stroke patients still die, half lose functional independence and more than 80% have residual functional deficits. The global burden of disease for stroke is 2-4 times that of all dementias combined (for mortality and disability adjusted life years, respectively, including Alzheimer’s) and is the second leading cause of death globally. NoNO has conducted three large, randomized, placebo-controlled trials (FRONTIER, ESCAPE-NA1 and ESCAPE-NEXT) demonstrating clinical proof of concept that nerinetide, a first-in-class PSD-95 inhibitor, can ‘help the brain hold its breath’ long enough for blood flow to be restored and improve outcomes. The results underscore the critical importance of rapid treatment – as soon as possible and at least within 3 hours of stroke onset – to improve outcomes for the 12.2 million annual cases and 101.5 million people living in the aftermath of stroke globally.

Injectable and biocompatible hydrogel from amyloidogenic peptide stretch of human tau306–311

Abstract

A vast majority of peptide hydrogelators harbor a bulky, non-native aromatic moiety. Such foreign moieties raise safety concerns as far as biomedical applications of hydrogels are concerned. The hydrogel research, therefore, has branched to another dimension– to identify native or native-like short peptide stretches that could cause the gelation of biological fluids. Using well-defined criteria to identify native peptide stretches that could form a viscous solution in water but cause gelation of phosphate-buffered saline (PBS), we identified the hexapeptide stretch from human tau, viz. tau306–311, as a promising injectable hydrogelator. The peptide causes instant gelation of PBS and the cell culture media. Such hydrogels find applications as drug delivery vehicles, scaffolds for mammalian cell culture, wound-dressing material, etc.

grabRNA: Smart RNA delivery enables novel therapeutic strategies

Abstract

Many diseases including various forms of cancer are not curable today since current therapeutics and modalities are not suitable to address the relevant biomolecular targets. Alongside the urgent need for new treatments in medicine, there is a growing demand for environmentally friendly innovations in agriculture, particularly for sustainable crop protection. In principle, RNA interference (RNAi) can enable the specific targeting of relevant biomolecules.This technology can be adopted and offers a highly specific and efficient tool to virtually suppress any desired target gene.

Despite RNAi’s vast potential, its broader application is hindered by significant challenges. Double-stranded RNA (dsRNA), the central component of RNAi, suffers from poor stability and limited cellular uptake. In relevant conditions, dsRNA is quickly degraded, reducing its effectiveness. Existing technologies have yet to provide a universal method to protect and stabilize dsRNA, limiting RNAi’s use in real-world applications.

Our innovative approach introduces a breakthrough solution based on synthetic peptides inspired by the tomato aspermy virus 2b (TAV2b) protein. These custom-designed peptides bind dsRNA, shielding it from degradation and preserving functionality. Once inside the cell, the peptides release the dsRNA in the reducing intracellular environment, allowing it to activate the RNAi machinery. Designed as a platform technology, our peptide stabilizers can bind any dsRNA sequence or length, making them broadly applicable across diverse fields. Their unique structure-specific interaction also allows seamless integration with existing RNA delivery systems, enhancing overall effectiveness.

RNAi is entering a new era and the field is advancing rapidly. However, delivery and stability remain the final barriers to widespread adoption. Our peptide-based stabilizers aim to overcome these hurdles. We are now demonstrating our technology in collaboration with global start-ups, unlocking RNAi’s full potential in medicine, biotechnology, and agriculture.

Identification of Novel Peptides for Targeted Delivery and Internalisation ​ via Transferrin Receptor 1 (TfR1) ​

The Orbit Peptide Discovery platform allows for the identification of highly efficacious peptide binders. There is renewed interest in the use of peptides as targeting agents for therapeutic delivery, particularly nucleic acid (eg siRNA) or radiopharmaceuticals. These peptides bind to specific disease or tissue specific biomarkers to allow for targeted action of a conjugated payload. Transferrin Receptor 1 (TfR1) has been a hotly pursued target, due to its ability to transcytose payloads across the Blood-Brain Barrier (BBB) for therapeutic delivery within the central nervous system. Its additional expression on the surface of muscle cells has also been exploited to deliver corrective nucleic acid in the treatment of Duchenne Muscular Dystrophy (DMD). Orbit has sought to leverage its unique affinity screening technology to identify novel peptide binders to TfR1. Subsequent validation in cells demonstrates that these peptides specifically bind TfR1 and bind in a manner non-competitive to the binding of transferrin. These hit peptides represent an ideal starting point for further development towards novel TfR1 specific treatments. ​
