ProtocolIn VitroADH-503 ((Z)-Leukadherin-1 choline; 4 μM; 8 days) reduces the numbers of total tumor-infiltrating CD11b+ cells and subsets of CD11b+ monocytes, granulocytes, eosinophils, and macrophages.
In VivoADH-503 (oral gavage; 30, 100 mg/kg; twice a day; on days 1 and 5) has the mean half-life of 4.68 and 3.95 hours, a maximum concentration of 1716 and 2594 ng/mL and AUC0-t in the plasma of 6950 and 13962 ng.h/mL at 30 and 100 mg/kg dosing, respectively. ADH-503 ((Z)-Leukadherin-1 choline; oral gavage; 30, 60, or 120 mg/kg; twice a day for 60 days) delayes tumor progression, leading to a significantly decreased tumor burden in time-point analysis and improved overall survival.
