How matched molecular pair analysis can support expert review of structural features associated with nitrosamine potency.
Matched molecular pair analysis compares closely related molecules that differ by a defined structural transformation and examines how that change relates to potency or another endpoint.
Why MMP is useful
It can isolate the effect of a local structural change more clearly than a broad similarity comparison.
Potency evidence
Pairs with relevant carcinogenicity or mutagenicity information can provide supporting evidence about an activating or attenuating fragment.
Context
The shared molecular context between the pair and the target nitrosamine affects how transferable the inference is.
Expert-review role
MMP supports a transparent argument but should not be treated as an automatic regulator or software decision.
Frequently asked questions
Is MMP the same as ordinary similarity search?
No. It focuses on defined structural transformations within a shared context.
Can MMP establish an acceptable intake by itself?
No.
Why is expert review important?
Because potency changes must be interpreted in chemical and toxicological context.
Can multiple pairs strengthen the argument?
Yes, when they show a consistent pattern.
