LAT1 inhibitor

Functions

Selective L-type amino acid transporter 1 inhibitor (LAT1 or SLC7A5; IC50 = 140 nM for ¹⁴C-leucine uptake in S2-hLAT1 cells, and 60 nM for HT29 human colon adenocarcinoma cells: growth inhibition IC50’s = 16.4 µM and 4.1 µM respectively for S2 and HT29  cells). Also active in HT-29 mouse xenograft models.  JPH203 is active in a variety of cancer models and has progressed to clinical trials. It sensitized A549 and MIA Paca-2 cells to radiation by enhancing cellular senescence via mTOR downregulation and sensitized EGFR-expressing cancer cell lines to gefitinib therapy.  JPH203 treatment of non-small cell lung cancer cells led to downregulation of PD-L1 suggesting that LAT1 inhibition may help overcome the immune suppressive tumor microenvironment.

Application Procedures

First dissolved in DMSO (up to at least 25 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 3 months.

Research use only.
