Notably, pimozide exhibited anti-tumor effects as a monotherapy and in combination with paclitaxel at clinically relevant doses. While tumor volume reduction in the combination group was not statistically greater than that in the monotherapy group, fluorescence immunohistochemistry revealed a marked decrease in undifferentiated tumor cells, indicating enhanced therapeutic effects of combination treatment. Taken together, these findings indicate that pimozide is a promising candidate for repurposing as a novel therapeutic agent against HNSCC.

STAT3 (Signal Transducer And Activator Of Transcription 3) • DRD2 (Dopamine Receptor D2) • EGR1 (Early Growth Response 1)
Although FLT3 tyrosine kinase inhibitors (TKIs), such as quizartinib (Quiz) and gilteritinib, have improved clinical outcomes, secondary TKD mutations, particularly the gatekeeper mutation F691L, confer significant resistance. Expression of constitutively active STAT5 partially rescued CPZ-induced growth inhibition. These findings suggest that STAT5 suppression is a key mechanism of CPZ's antileukemic activity and support its potential as a therapeutic strategy for FLT3-ITD-positive AML.

FLT3 (Fms-related tyrosine kinase 3) • STAT5A (Signal Transducer And Activator Of Transcription 5A)
In this study, drug repurposing agent's metformin, chlorpromazine (CPZ) alone and combine were tested on both clinical and laboratory ovarian cancer samples to evaluate on hemocytometer and clonogenic assay for dead cell and proliferation respectively. The resulting data were analyzed to achieve successfully known target region and worked as a bridge between clinical and laboratory model. The insights gained from this study not only validate OVCAR3 as a representative model for HGSOC but also provide a foundation for developing targeted therapeutic strategies.
