unchanged parent enzalutamide

English to Portuguese Medical Medical: Cardiology Medicina - oncologia
A trace amount of unchanged parent enzalutamide was excreted in urine. N-Desmethyl enzalutamide was too low to quantitate in urine by LC–MS/MS.

Não consigo saber o q seria parent. Não encontro em nenhum texto científico em português, mas isso aparece em inglês. Podem ajudar?

Onrigada

I need to know in Portuguese, But, anyway, thanks
Marjolein Snippe Mar 5, 2020:
I don't know how to say this in Portuguese but... the parent substance is the original substance that was administered (enzalutamide, in this case), without any modifications through metabolization. (In contrast, N-desmethyl enzalutamide would be enzalutimide to which an N-desmethyl group has been added.)

See https://toxtutor.nlm.nih.gov/12-001.html
"Detoxification occurs when biotransformation results in metabolites of lower toxicity. In many cases, however, the metabolites are more toxic than the parent substance, a process called bioactivation."

or

https://www.ncbi.nlm.nih.gov/pubmed/2388874
Allopurinol and caffeine have been used to measure metabolite formation followed by renal elimination of both parent substance and metabolite.

Google "parent substance" for more examples (or try a combination, eg. "parent substance" with "metabolized").

enzalutamida original

Com a explicação da Marjolein, acredito que o termo se refira ao medicamento em seu estado original, sem modificações.
