Scientific capability / Logic-Gated Drug Activation

Specify where a drug should switch on.

A trigger can be present in both diseased and healthy tissue. BioTwin’s logic-gated activation methods let a team specify combinations of conditions and the biological settings in which activation should remain off.

Current work Mechanism specification

Write both halves of the activation rule

A single-trigger concept starts with a condition such as low pH or a particular enzyme. A multi-trigger specification makes the intended combination explicit, potentially using hypoxia, enzyme or microbiome context. Equally important are the negative cases: which neighboring or healthy environments could satisfy part of the rule?

Turn the rule into a chemistry question

The current work supports mechanism specifications and executable Boolean conditions. The next step is to identify chemistry that can implement the rule, then measure activation and leakage across the relevant environments. A correct logical specification is only the beginning of a useful prodrug.

Exposure decides which conditions the molecule encounters

A proposed activation gate should be assessed alongside tissue exposure and the rate of conversion. Those are separate modeling questions that could be joined once the chemical mechanism and biological setting are defined.

  • Exposure and barriers · Investigate whether the molecule reaches the intended activating environment. Exposure and barriers
  • Local effect · Ask whether local activation could produce a useful separation in effect. Local effect

Name the conditions that should keep the drug off.

Pair the desired activation setting with the most important negative contexts. Then assess what chemistry and measurements the rule requires.
