Degrader Assessment & Validation Support

Ternary Complex Analysis, DMPK Prediction and Data Interpretation

Computational assessment of degrader candidates: ternary complex analysis, selectivity and off-target degradation risk, ADMET and DMPK prediction, and interpretation of degradation and proteomics data.

Overview

Degrader assessment asks a different question from inhibitor assessment. Occupancy is not the endpoint, catalytic behaviour matters, and selectivity has to be judged at the level of the degraded proteome rather than the bound target. We support that assessment computationally: analysing ternary complexes, predicting ADMET and DMPK properties for molecules well outside conventional property space, and interpreting the degradation and proteomics data that establish whether a compound does what it is supposed to.

Schematic: properties are predicted across the series and each liability is attributed to the substructure responsible, so the result points to a modification.

Key Advantages

01

Selectivity Judged Proteome-Wide

Neo-substrate and off-target degradation risk is assessed against the surface and sequence features that drive it, and global proteomics data is analysed where it exists.

02

DMPK Prediction Fit For Purpose

Property prediction uses models appropriate to beyond-rule-of-five chemistry, and states where a compound sits outside the applicability domain rather than returning a confident-looking number.

03

Degradation Data Interpreted Properly

DC50, Dmax, hook behaviour and kinetics are analysed together, since a compound with excellent DC50 and poor Dmax is a different problem from the reverse.

04

Structure Linked To Behaviour

Observed degradation differences across a series are related back to the ternary models, which is what turns an assay result into a design instruction.

Questions We Are Asked Before Scoping

Can you predict DC50 or Dmax?

  • No. Both depend on cellular ubiquitination and proteasome processing that computation does not resolve. We explain observed differences structurally and predict properties, which is a narrower but genuinely useful contribution.

How do we assess selectivity properly?

  • Global proteomics after treatment is the standard approach. We help design the experiment and analyse the data, including the statistics that separate genuine off-target degradation from variability.

Is computational DMPK reliable for degraders?

  • Less so than for conventional small molecules, because most models were trained on rule-of-five chemistry. We say where a compound falls outside the applicability domain instead of quoting a number regardless.

Interpretation and Limitations

This is a computational (in silico) service. Designs and predictions prioritise hypotheses and direct experimental effort; they do not by themselves establish that an edit, construct, molecule or assay will perform as intended. Laboratory execution — editing, cloning, expression, synthesis and testing — is planned with you and carried out by your own team or a qualified partner. Deliverables are for research use only and are not intended for diagnostic or therapeutic use.

Service Workflow

Step 01

Scientific Consultation

We discuss the objective, the decision it supports and the material and data you already hold.

Step 02

Feasibility Review

We check that the target, system and available information can support the approach, and say plainly where they cannot.

Step 03

Technical Proposal

Scope, methods, deliverables, timeline and price are confirmed in writing, together with the limitations we expect to report.

Step 04

Design and Analysis

The design work runs on documented tools and parameters, with quality checks and alternatives compared where that is informative.

Step 05

Delivery and Follow-Up

You receive the designs, the supporting analysis and a validation plan, plus support interpreting the results once the experiments run.

Is This the Right Service for You?

Choose this service when

A candidate is approaching in vivo work and needs a computational assessment
Two close analogues behave differently and the reason is unclear
Proteomics data from degrader treatment needs proper analysis

Consider another service when

What Goes Wrong, and How We Handle It

The failure modes that produce confident-looking results which do not survive the next experiment. Each one is designed against rather than discovered afterwards.

Proteome-wide analysis is recommended and analysed with statistics matched to the design, since off-target degradation is the question.

Case Studies

The situation
A methyl group difference changed Dmax substantially while binary affinity was unchanged.
What the work involved
Ternary complexes were modelled and simulated for both, interface contacts were compared, and the degradation data was analysed against the structural difference.
What came back
The methyl group added a contact at the target–ligase interface that stabilised the complex. Six further designs exploited the same contact, and the interface was flagged as the thing to optimise.

Illustrative of the shape this work takes. Details are generalised, no client or target is identified, and scope and outcome vary with the system in question.

Note: ICDMO delivers computational (in silico) services. Results prioritise hypotheses for testing; they do not by themselves establish binding, biological activity, efficacy or safety. All deliverables are for research use only and are not intended for diagnostic or therapeutic use. Downstream experimental work is scoped separately and executed through qualified partners.
