In Silico Evaluation of Haloalkylated TSPO PET Tracer Candidates for Traumatic Brain Injury Neuroinflammation
This repository contains code, processed data, figures, and supplementary materials for a computational study prioritizing haloalkylated emapunil-derived TSPO PET tracer candidates for traumatic brain injury neuroinflammation.
The workflow includes reference TSPO tracer scoring, AC-5216/emapunil pharmacophore selection, analog enumeration, CNS-MPO filtering, AutoDock Vina docking, PBPK-derived candidate ranking, and Logan graphical analysis of simulated time–activity curves.
This project is entirely computational. The proposed analogs should be interpreted as prioritized candidates for future radiosynthesis, TSPO binding assays, autoradiography, and preclinical TBI PET validation, not as experimentally validated radiotracers.
