AUTAC Degradation Technology Development

BOC Sciences provides solution-oriented AUTAC development services for researchers seeking autophagy-based targeted degradation strategies beyond classical proteasome-dependent modalities. AUTACs (autophagy-targeting chimeras) are a targeted degradation technology that directs intracellular substrates to the autophagy–lysosome pathway for selective clearance. Unlike traditional small-molecule inhibitors, which mainly block protein function, AUTACs are designed to eliminate the target itself. A key advantage of this approach is its potential to address a wider range of intracellular cargo, including proteins, protein aggregates, and dysfunctional organelles, making it especially attractive for targets that are difficult to handle with conventional pharmacology or standard degrader formats. By combining the functional benefits of targeted clearance with the biological relevance of autophagy, AUTACs offer a valuable strategy for mechanism-driven discovery and next-generation degrader research.

Our scientific approach is especially valuable for teams evaluating aggregate-prone proteins, autophagy-relevant oncology targets, mitochondrial quality-control projects, and other intracellular substrates for which lysosomal clearance may offer a more suitable degradation route. For clients comparing pathway options across broader lysosomal-based degradation technology development strategies, we help define when AUTAC is the right fit and how to structure a practical discovery workflow.

BOC Sciences' Comprehensive AUTAC Development Services

Target Selection and AUTAC Feasibility Assessment

AUTAC success starts with choosing the right biological entry point. We evaluate substrate accessibility, subcellular localization, disease relevance, known ligandability, autophagy compatibility, and the likelihood that lysosomal routing can create a measurable functional benefit. This early-stage work helps clients avoid investing in targets that may bind well but fail to generate productive autophagic clearance.

• Biology review for intracellular proteins, aggregates, and organelle-related targets
• Target tractability assessment supported by target protein services
• AUTAC suitability analysis versus proteasomal or alternative lysosomal modalities
• Early project risk mapping for autophagy dependence, readout design, and substrate selectivity

Warhead and Degradation-Tag Design

We design AUTAC architectures around target-binding elements, degradation tags, and conjugation logic that can support productive autophagic recruitment while preserving binding affinity and cellular compatibility. Depending on the project, we can start from known binders, fragment-derived leads, or new ligand hypotheses generated through structure-informed design.

• Ligand design for target protein
• Evaluation of small-molecule versus peptide-derived targeting strategies
• Guanine-tag and autophagy-recruiting motif selection
• Conjugation-site prioritization for balanced binding and degradation performance

Linker Engineering and Architecture Optimization

AUTAC molecules often fail not because the concept is wrong, but because geometry, flexibility, polarity, or steric presentation prevents efficient cargo recognition by the autophagy machinery. We optimize linker length, rigidity, attachment position, and physicochemical balance to improve intracellular exposure and degradation efficiency.

• Linker design and optimization services
• Linker attachment-site analysis for target-facing and tag-facing domains
• Focused analog design to probe spatial presentation and degradation trends
• Structure–activity and structure–degradation relationship interpretation

AUTAC Synthesis and Focused Library Generation

We provide synthetic support for hit confirmation, analog expansion, and mechanism-oriented chemistry iteration. For discovery-stage programs, we can build compact AUTAC series around prioritized hypotheses so that clients obtain interpretable datasets rather than isolated single-compound results.

• Route scouting and AUTAC synthesis planning
• Parallel preparation of focused AUTAC analog panels
• Access to supporting chemical space through our screening library
• Negative-control and non-degrading analog design for mechanism studies

Cell-Based Degradation and Mechanistic Validation

Since AUTAC programs are highly mechanism-sensitive, we emphasize rigorous cellular testing rather than relying on binding data alone. Our workflow examines degradation efficiency, time dependence, dose response, autophagy dependence, and downstream phenotypic consequences so clients can distinguish genuine AUTAC activity from nonspecific cytotoxicity or pathway stress.

• Intracellular uptake and localization assessment
• Live-Cell Assay design for kinetic monitoring
• Quantitative degradation ability assay workflows
• Autophagy-marker, lysosomal-dependence, and rescue-experiment validation

Developability Evaluation and Modality Positioning

AUTAC discovery requires balancing degradation activity with permeability, solubility, intracellular exposure, and project scalability. We help clients understand whether a promising degrader series should remain in AUTAC format, be further optimized, or be benchmarked against adjacent autophagy-based modalities such as ATTEC degradation technology development when direct LC3-associated recruitment may better match the biology.

• Physicochemical and exposure-oriented optimization guidance
• Modality comparison for AUTAC versus related autophagy-based approaches
• Candidate prioritization based on mechanism, robustness, and scalability
• Decision support for next-round chemistry and biology planning

Our Solutions for Key AUTAC Development Bottlenecks

AUTAC projects often fail at the interface between chemistry, cell biology, and mechanistic interpretation. BOC Sciences addresses this by integrating design and validation into a single decision-making workflow rather than treating synthesis and biology as separate activities.

Solution for Selecting the Right AUTAC Target

We assess disease relevance, intracellular accessibility, expected substrate turnover, and the practical value of lysosomal clearance. This is particularly important for teams working on aggregation-prone proteins, mitochondrial dysfunction, and targets where catalytic inhibition alone is unlikely to deliver the desired biology.

Solution for Efficient AUTAC Design Hypothesis Generation

By combining literature mining, structure-aware design, and virtual screening, we rapidly generate prioritized AUTAC hypotheses instead of relying on low-efficiency trial-and-error chemistry. This improves the chance of identifying compounds that preserve binding while enabling productive autophagy recruitment.

Solution for Mechanistic Proof of Degradation

We design multi-layer validation packages including protein-level quantification, autophagy-marker analysis, pathway inhibition controls, washout experiments, and phenotypic confirmation. This helps clients determine whether an observed signal reflects true AUTAC-mediated cargo clearance or only indirect pathway modulation.

Solution for Balancing Activity and Developability

We optimize compound series across degradation potency, exposure-related properties, selectivity, and experimental robustness so clients can make better advancement decisions. This is especially important for AUTAC molecules, where increased molecular complexity can quickly create trade-offs in cell penetration and assay interpretation.

Advantages of AUTAC Degradation Technology

Expands Degradation Beyond Proteasome-Favored Substrates

AUTAC leverages the autophagy–lysosome pathway, creating opportunities for intracellular substrates that may be challenging for purely proteasome-driven degradation strategies.

Potentially Relevant for Aggregates and Organelle-Associated Biology

Because autophagy is naturally involved in the handling of larger intracellular cargo, AUTAC is attractive for projects involving protein assemblies, damaged mitochondria, and related cellular debris.

Supports Mechanism-Driven Research in Selective Autophagy

AUTAC is not only a potential discovery modality but also a valuable chemical biology tool for studying how selective autophagy can be redirected toward disease-relevant substrates.

Complements Rather Than Replaces Other TPD Modalities

AUTAC broadens the targeted degradation toolbox and can be strategically compared with PROTAC, ATTEC, and other approaches to identify the most suitable route for a specific target class.
