Background:

• Local nonequilibrium approaches are crucial for understanding biological systems, including cancer development and drug-target interactions.
• The phosphoinositide 3-kinase (PI3K) enzyme is a significant target in cancer therapy.
• 2-(2'-hydroxy-4'-aminophenyl)benzothiazole (HABT) is a molecule with potential applications in cancer diagnosis.

Purpose of the Study:

• To investigate the Excited State Intramolecular Proton Transfer (ESIPT) performance of HABT when interacting with the PI3K enzyme.
• To analyze HABT's spectroscopic properties within a local nonequilibrium regime.
• To explore the metastable states of HABT in the context of protein-ligand interactions.

Main Methods:
