MedKoo Cat#: 406760 | Name: JPH203 free base
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

JPH203, also known as KYT-0353, is a potent and selective LAT1 selective ( L-type amino acid transporter 1) inhibitor. JPH203 can very potently inhibit l-leucine uptake. JPH203 inhibits YD-38 cell growth. JPH203 up-regulated the population of apoptotic YD-38 cells through the activation of apoptotic factors, including caspases and PARP.

Biological target:
JPH203 is a L-type amino acid transporter 1 (LAT-1) inhibitor.
In vitro activity:
The specific inhibition of LAT1 with JPH203 decreased LS174T proliferation by 60% (Fig. 3A and B, left). Consistent with the results for mTORC1 and GCN2 activity, LS174T-CD98KOand A549-CD98KD cells were able to maintain their proliferation at the same level as WT cells (Fig. 3A and B and Supplementary Fig. S3C). Furthermore, it was confirmed that this LAT1KO-specific antiproliferative effect (70% reduction) was observed in 3D culture assays (Fig. 3C). These findings demonstrate the essential role of LAT1 for maintenance of tumor cell AA homeostasis and proliferation. Reference: Cancer Res. 2016 Aug 1;76(15):4481-92. https://cancerres.aacrjournals.org/content/76/15/4481.long
In vivo activity:
Thyroid tumorigenesis was induced in 6-weeks old adult BrafCA/+;Pik3caLat/+;Thyro::CreERT2 mice by tamoxifen injection, which results in thyrocyte-specific expression of BRAFV600E and PIK3CAH1047R. A cohort of 12 mice was separated into two groups that were treated with either vehicle or 50 mg/kg JPH203 i.p. daily for five days per week during 6.5 weeks (Fig. 5a). Weekly ultrasound imaging revealed that JPH203 exerted an arrest of tumor growth already after 14 days of treatment, whereas tumors of vehicle-treated mice continued to grow until the end of the experiment (Fig. 5c). This data shows that LAT1 plays a critical role in tumor growth in mice, suggesting that LAT1 helps cells grow in the physiological environment that is low in amino acids.
