Unlocking the Potential of Cyclic and Conjugated Peptides Through Integrated Discovery and Development

Real-World Strategies and Case Studies

Peptide therapeutics are opening new opportunities to address challenging biological targets that are difficult to reach with traditional small molecules and biologics. Among these, cyclic and conjugated peptides have emerged as promising modalities. Cyclization can enhance peptide stability, potency, and selectivity, while conjugation can improve targeting, tissue distribution, half-life, and overall therapeutic performance. Despite their potential, the development of these molecules often involves significant challenges in synthesis, scale-up, manufacturability, and DMPK optimization.

What you'll learn:

In this webinar, Dr. Arijit Banerjee will discuss how Aragen’s PeptARx platform enables the integrated discovery, development, and scalable manufacture of complex peptides and peptide conjugates. By combining design, synthesis, screening, DMPK evaluation, and development expertise within a single platform, PeptARx helps accelerate timelines while reducing development risk.

Through real-world case studies, attendees will learn how challenging peptide conjugates were successfully synthesized and advanced, and how key synthesis, developability, and DMPK hurdles associated with cyclic peptides were overcome to support candidate progression.

Key takeaways:

  • Design principles for cyclic and conjugated peptides
  • Strategies to overcome synthesis and scale-up challenges
  • Approaches to optimize stability, permeability, and pharmacokinetic properties
  • Case studies highlighting successful development of complex peptide modalities
  • How Aragen’s PeptARx platform delivers speed, integration, and scale from discovery to development

Frequently Asked Questions

Most large peptide CDMOs — including Bachem, PolyPeptide, and CordenPharma — focus exclusively on manufacturing and do not offer discovery biology, assay development, or DMPK services. This means that after they synthesise your peptide, you need to engage separate vendors for biological screening and ADME profiling, creating fragmented workflows and delayed decision-making. PeptARx is fundamentally different. It integrates peptide chemistry (130 scientists), assay development & screening (75 scientists, 500+ validated assays), and DMPK (109-person team, <7-day turnaround) into a single discovery workflow at one site in Hyderabad.

PeptARx supports virtually every class of therapeutic and research-grade peptide, including:

  • Linear, branched, cyclic, bi-cyclic, and stapled peptides
  • Macrocyclic peptides and conformationally constrained designs (on-resin and off-resin cyclisation)
  • Peptide conjugates — lipid, steroid, small molecule, carbohydrate, PEG, DOTA, fluorophore
  • Peptide-drug conjugates (PDCs), peptide-PMO (PPMO), and peptide-oligonucleotide conjugates (POC)
  • Long peptides and synthetic protein fragments (up to 150+ amino acids) via NCL and KAHA ligation
  • Peptidomimetics and N-alkylated, β-amino acid, and glycosylated amino acid-containing sequences

Within peptide discovery programs, Aragen’s DMPK team helps de-risk candidates through targeted assessment of gastrointestinal, plasma, hepatic, intestinal, and renal stability; metabolite identification; permeability and PEPT transporter studies; and quantitative LC-MS/MS bioanalysis. Integrated with tissue distribution and pharmacokinetic studies across preclinical species, these assays provide actionable insights into peptide absorption, clearance, and exposure, enabling rapid design iterations and informed candidate selection

For peptide discovery programs, Aragen develops and deploys tailored biochemical and cell-based assays to assess target binding, receptor activation, signaling, and functional responses. Capabilities include peptide-protein interaction studies by SPR, HTRF-based binding and cytokine assays, AlphaLISA orthogonal validation, GPCR functional assays, and high-throughput screening in 384-well formats, enabling efficient identification and optimization of peptide leads with the desired potency and mechanism of action
