LC–MS/MS Traces GS-441524 Prodrug Activation
2026-09-04
A January 2026 Microchemical Journal study established an LC–MS/MS strategy to follow conversion of the novel GS-441524 prodrug NGP-1 into GS441 in gastric fluid, blood, liver microsomes, and liver-injury model rats. The work provides a matrix-resolved framework for interpreting prodrug stability, hepatic metabolism, systemic hydrolysis, and GS-441524 pharmacokinetics during preclinical development.
