V-9302 hydrochloride is a competitive antagonist of transmembrane glutamine flux. V-9302 hydrochloride selectively and potently targets the amino acid transporter ASCT2 (SLC1A5) not ASCT1. V-9302 hydrochloride inhibits ASCT2-mediated glutamine uptake (IC50=9.6 µM) in HEK-293 cells.

Cell lines | HCC1806 cells |
Preparation method | Immunofluorescence HCC1806 cells were treated V-9302 (25 µM aqueous, 1% DMSO) for 48 h. Following treatment, cells were fixed with 70% methanol for 5-10 min. LC3B was visualized with 1:100 primary antibody (anti LC3B) at 37 ºC for 45 min followed by application of 1:600 secondary antibody (Rhodamine Red) at 37 ºC for 30 min and DAPI for 4 min. Images were acquired with a fluorescence microscope at visualized at 40× magnification. |

Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
