Elucidating the Solvent‐Dependent Solvation and Structural Stability of Irinotecan: A Molecular Simulation Study

open access: yesChemPhysChem, Volume 27, Issue 8, 28 April 2026.
The solvation preference of irinotecan is governed by a competition between cavity formation and electrostatic stabilization. Computations reveal that the high cost of breaking water's hydrogen bond network outweighs its electrostatic benefits. In contrast, polar aprotic solvents (e.g., pyridine) offer an optimal thermodynamic balance, providing strong
