Homogeneous suspension
CMC-NA
≥5mg/ml
Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble. * Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. * Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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 (Cell-free assay)
In vitro
Nanvuranlat (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. It inhibited HT-29 cell growth, generating an apparent IC50 of 4.1 μM, but the 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. This compound activated the mitochondria-dependent apoptotic signalling 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. It can distinguish relative abundance between LAT1 and LAT2, and has high selectivity for LAT1. JPH203 was metabolically stable in mouse, rat, dog, monkey and human liver microsomal incubations. It 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.
In Vivo
Daily intravenous administration of JPH203 (12.5 and 25 mg/kg) significantly inhibited tumour 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, this compound shows anti-tumour efficacy in nude mice bearing human cholangiocarcinoma (CCA) cell xenografts without general toxicity.
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 Nanvuranlat (JPH203) for 72 h. This compound is then 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.
