inS3-54A18

Animal experiment:

Briefly, 5×106 A549 cells are injected subcutaneously in the flanks of 5-6-week-old male NOD/SCID mice. When the tumor volume reach about 50.0 mm3, the mice are randomized using online program into two different groups (6/group) with one group treated by formulation vehicle control and the other by A18 at 200 mg/kg with oral dosing 2-3 times a week for 4 weeks. One mouse in each group dies during the study and is eliminated. Tumor volume and body weight of the remaining five mice in each group are measured twice a week without blinding. On the thirty-fifth day after implant, mice are euthanized and the tumor tissues are harvested and weighed. Necropsy is also performed to determine changes in the heart, lungs, kidneys, liver and spleen.
