AlanPepAI™ is an AI-assisted platform for linear peptide design and sequence optimization. It combines structure-guided peptide generation, peptide–protein structural modeling, molecular docking, and multi-parameter candidate ranking to help researchers prioritize promising peptide sequences before experimental synthesis and validation.
AlanPepAI™ can be used to optimize an existing peptide sequence or generate and evaluate new peptide candidates using structural information from a target protein.
The goal is to reduce a large virtual design space into a focused set of peptide candidates for synthesis and experimental testing.

AlanPepAI™ Workflow
1. Define the Target and Starting Peptide
A project begins with available structural and sequence information. Users can provide a target protein structure and, for peptide optimization projects, an existing linear peptide sequence.
Additional information such as a known or proposed binding region and the desired optimization objective can also be incorporated into the project.
2. Structure-Guided Peptide Design
AlanPepAI™ explores alternative peptide designs according to the structural environment of the target and the selected optimization strategy.
Structure-guided methods such as RFdiffusion and ProteinMPNN can be incorporated into the workflow to generate peptide backbones and alternative amino acid sequences based on structural context.
3. Peptide–Protein Structural Modeling
Generated peptide candidates are evaluated in the context of the target protein. Structure-prediction and complex-modeling methods can be used to examine whether candidate sequences are structurally compatible with the proposed peptide–target interaction.
4. Peptide–Protein Docking
AlanPepAI™ incorporates peptide-focused docking workflows, including AutoDock CrankPep (ADCP), to explore potential peptide binding modes against the target structure.
Docking provides predicted peptide conformations, binding poses, and interaction-related information that can be used as part of candidate comparison.
5. Multi-Parameter Candidate Ranking
AlanPepAI™ compares peptide candidates using multiple computational parameters rather than relying on a single score.
Depending on the workflow, candidate information may include:
Optimized peptide sequence
Global ranking score
Molecular weight
Isoelectric point
Hydrophobicity
Docking or interaction-related scores
Predicted structural information
The result is a prioritized set of candidates that can be selected for downstream peptide synthesis and experimental validation.

Applications of AlanPepAI™
Existing Peptide Optimization
Start from an existing peptide sequence and explore alternative amino acid combinations that may improve predicted target interactions or other selected design properties.
Target-Based Peptide Design
Use structural information from a protein target to generate and evaluate potential linear peptide binders.
Peptide Candidate Prioritization
Evaluate a larger set of computationally generated candidates and select a smaller number of peptides for experimental synthesis and testing.
Structure–Activity Exploration
Investigate how sequence substitutions may influence predicted peptide structure, target interactions, and selected physicochemical properties.
From AI Peptide Design to Experimental Synthesis
AlanPepAI™ connects computational peptide design with Alan Scientific's Custom Peptide Synthesis capabilities.
Computationally prioritized candidates can move directly into peptide synthesis for experimental evaluation.
Target / Starting Peptide → AI Design → Structural Evaluation → Candidate Ranking → Peptide Synthesis → Experimental Validation
This integrated workflow helps researchers move from virtual peptide design to physical candidate testing while maintaining continuity between computational and experimental project requirements.
Understanding AlanPepAI™ Predictions
AlanPepAI™ is a computational peptide design and candidate-prioritization platform.
Predicted structures, docking poses, interaction scores, physicochemical properties, and candidate rankings are computational estimates. They should not be interpreted as experimental measurements of binding affinity, biological activity, stability, or efficacy.
Experimental synthesis and biological validation remain necessary to confirm peptide performance.
