Druggability Rationale: MCT1 is tractable for small-molecule modulation (druggability score 0.60) due to its well-characterized transmembrane topology and proof-of-concept from existing inhibitors like AZD3965 in clinical trials. However, the transporter class presents challenges in achieving selective modulation without disrupting essential metabolic functions, and the therapeutic strategy requires fine-tuned restoration of MCT1/MCT4 balance rather than simple inhibition.
Mechanism: Transporter modulation — restoring MCT1/MCT4 balance to normalize astrocyte-neuron metabolic coupling

Selectivity & Safety Considerations

Selective MCT1 inhibition must avoid off-target effects on MCT2, MCT3, and MCT4 to prevent disrupting the astrocyte-neuron lactate shuttle; peripheral MCT1 expression in red blood cells, intestine, and skeletal muscle presents additional selectivity challenges and potential toxicity risks that require brain-penetrant, CNS-selective chemical scaffolds.
