AZD-0364 (Synonyms: AZD0364)

Cell experiment:

KRAS-mutant Non-Small Cell Lung Cancer (NSCLC) A549, H2122, H2009, and Calu6 cell lines are seeded in 384-well black, clear bottomed plates, cultured for 18-24 hours and treated with increasing concentrations of AZD-0364 (7.143 nM, 61 nM, 357 nM, 2.143 μM and 10 μM) and Selumetinib (0-10 μM) in a 6×6 dosing matrix. Cells are seeded at a concentration such that cells in untreated wells are approximately 80% confluent at the end of the assay. After 3 days of treatment, live cell number is determined using a Sytox Green endpoint[1].

Animal experiment:

Mice[1]A549 is a human non small cell lung cancer line carrying an oncogenic mutation in the KRAS gene (G12S). Female nude mice are implanted subcutaneously (s.c.) on the left flank, with 5×106 A549 cells (ATCC) per mouse.Tumor growth is monitored by twice weekly calliper measurement and volumes are calculated. Once tumors have reached a volume of ~200-300mm3 animals are randomised into groups of 7-11 and are treated with a continuous combination schedule of Selumetinib (ARRY-142886) 25 mg/kg BiD and AZD-0364 ethanesulfonic acid 25 mg/kg QD (four hours after first Selumetinib dose), both are dosed by peroral route. Tumor volumes are measured twice weekly after dosing commenced[1].
