Nanvuranlat (JPH203)

Synonyms: KYT-0353, JPH-203SBECD

Nanvuranlat (JPH203, KYT-0353, JPH-203SBECD), a selective L-type amino acid transporter 1 inhibitor, shows a dramatic inhibition of leucine uptake (IC50=0.06 µM) and cell growth (IC50=4.1 µM) in human colon cancer cells (HT-29), human oral cancer cells (YD-38) and leukemic cells.

Biological Activity

Description Nanvuranlat (JPH203, KYT-0353, JPH-203SBECD), a selective L-type amino acid transporter 1 inhibitor, shows a dramatic inhibition of leucine uptake (IC50=0.06 µM) and cell growth (IC50=4.1 µM) in human colon cancer cells (HT-29), human oral cancer cells (YD-38) and leukemic cells.
Targets
LAT1 [1]
(Cell-free assay)
In vitro
In vitro JPH203 completely and slightly inhibited the L-Leucine uptake in YD-38 cells (IC50 value: 0.79 μM) and NHOKs (IC50 value: >100 μM), respectively. JPH203 inhibited HT-29 cell growth, generating an apparent IC50 of 4.1 μM, but the JPH203 IC50 concentration (0.06 μM) needed to inhibit the L-Leucine uptake did not inhibit HT-29 cell growth, which represents a 68-fold difference in susceptibility[1]. JPH203 activated the mitochondria-dependent apoptotic signaling pathway by upregulating pro-apoptotic factors, such as Bad, Bax, and Bak, and the active form of caspase-9, and downregulating anti-apoptotic factors, such as Bcl-2 and Bcl-xL in Saos2 human osteosarcoma cells. JPH203 can distinguish relative abundance between LAT1 and LAT2. It has high selectivity for LAT1[2]. JPH203 was metabolically stable in mouse, rat, dog, monkey and human liver microsomal incubations[3]. JPH203 induces both G2/M and G0/G1 cell cycle arrest, as well as reduced the S phase accompanied by altered expression of the proteins in cell cycle progression: cyclin D1, CDK4, and CDK6[4].

Concentrations 100 µM
Incubation Time 72 h
Method

Colony formation assays are performed by seeding 300 cells/well into 6 well plates. After 24 h of growth, the cells are treated with 100 µM JPH203 for 72 h. The JPH203 treatment is removed and fresh medium is added. The cells are incubated for 10 days. Thereafter, medium is removed and the cells are washed with phosphate buffered saline (PBS) and fixed with 4% paraformaldehyde for 10 min at 4℃. Sequentially, the colonies are stained with 2% crystal violet for 10 min. Finally, colonies stained by crystal violet are washed with PBS and dried at room temperature, before imaged by a digital camera.

In Vivo
In vivo Daily intravenous administration of JPH203 (12.5 and 25 mg/kg) significantly inhibited tumor growth in KKU-213 cholangiocarcinoma cell xenografts in the nude mice model in a dose-dependent manner with no statistically significant change in the animal’s body weight and with no differences in the histology and appearance of the internal organs compared with the control group. Thus, JPH203 shows anti-tumor efficacy in nude mice bearing human cholangiocarcinom (CCA) cell xenografts without general toxicity[4].
