The pharmaceutical industry is undergoing a profound transformation, with AI-driven drug discovery revolutionizing how new therapeutics are developed. Machine learning (ML), including deep learning and generative AI, is accelerating drug candidate identification, optimizing molecular structures, and reducing costs. Key applications, such as AI for target identification, virtual screening, and predictive modeling, are streamlining drug development and increasing success rates.
AI is reshaping peptide-based drug discovery by enabling rapid design, activity prediction, and optimization of novel therapeutics. These advances bypass traditional trial-and-error methods, expediting the path from concept to candidate selection.

AI-driven peptide discovery
AI-driven approaches, such as deep learning models and predictive screening, are transforming peptide discovery by enabling the design and selection of potent drug candidates at unprecedented speed.
Traditional peptide drug discovery has been hindered by limited native peptide ligands and labor-intensive optimization processes. Now, machine learning models can design peptides from scratch, optimizing their properties with high accuracy.
Gubra’s AI-powered drug discovery approach
Gubra is leveraging AI-driven methodologies to accelerate peptide-based drug discovery. Central to this is de novo peptide design, where entirely new sequences are generated to fit a desired target. By integrating AlphaFold for structure prediction and generative models like proteinMPNN—which proposes amino acid sequences that are compatible with a given 3D backbone—, Gubra’s platform designs and optimizes novel peptides with high receptor potency, and beneficial drug-properties.
Machine Learning (ML)-guided peptide optimization
Beyond AI-driven de novo peptide design, Gubra also leverages machine learning for peptide optimization through its drug discovery platform, streaMLine. This platform combines high-throughput data generation with advanced AI models to guide the selection of the most promising drug candidates. By integrating experimental data with predictive modeling, streaMLine enables informed decision-making in the drug discovery process. In a parallelized setup, the platform simultaneously optimizes for potency, selectivity, and stability, thus accelerating timelines and the success rate of new drug candidates.

The streaMLine platform
How streaMLine is transforming peptide drug development
streaMLine represents a paradigm shift in peptide drug discovery, integrating AI into optimization of peptides. By leveraging machine learning, the platform systematically refines peptide candidates, ensuring they meet stringent drug-like criteria such as efficacy, specificity and long half-life.
One of the key applications of streaMLine was demonstrated in the development of novel GLP-1 receptor (GLP-1R) agonist based on a secretin backbone. By leveraging AI-guided design, the platform:
- Enhanced receptor selectivity: AI-driven substitutions improved GLP-1R affinity while abolishing off-target effects.
- Optimized stability: Modifications reduced peptide aggregation and improved solubility.
- Achieved long-acting efficacy: In vivo studies demonstrated potent weight-loss effects in diet-induced obese (DIO) mice, and a PK profile compatible with once-weekly dosing.
This AI-powered approach underscores the impact of machine learning in drug discovery, accelerating the transition from in silico modeling to functional peptide drug candidates.

Deep learning models like AlphaFold and RFdiffusion are enabling the design of drug candidates for previously ‘undruggable’ disease targets
