MTX-101: Target-Level Mechanism

MTX-101 binds selectively to the tumor-associated nutrient transporter, inhibiting substrate translocation across the plasma membrane.

Key features of inhibition:
• High selectivity over related transporter family members
• Competitive inhibition of substrate uptake
• Nanomolar potency in tumor cell models
• Favorable pharmacokinetics supporting sustained target engagement

By limiting nutrient influx, MTX-101 reduces intracellular substrate availability required for:
• Glycolytic flux and alternative sugar metabolism
• Lipid and nucleotide biosynthesis
• Oncogenic signaling pathway activation
