ATM-3507 trihydrochloride is a potenttropomyosininhibitor withIC₅₀s from 3.83-6.84 μM in human melanoma cell lines.

IC50: 3.83-6.84 μM (tropomyosin, in human melanoma celllines)^[1].

The maximal tolerance dose (MTD) for TR100 and ATM-3507 is 60 and 150 mg/kg, respectively. It is found that a significant inhibition of tumor growth and prolongation of animal survival using either combination compared with each monotherapy. The median survival of mice increased from 18 days for mice treated with ATM-3507 to more than 49 days for mice treated with the combination. It is also found that twice weekly intravenous administration of ATM-3507 also show combination efficacy. The impact of each treatment or the combination on body weight is minimal. Drug levels are measured following the intravenous administration of ATM-3507 at 30 mg/kg in Balb/c mice (n=3 per time point). The mean half-life of ATM-3507 is 5.01 hrs for the terminal elimination phase. The mean AUC_0-tin the plasma is 14,548 ng/h/mL. The C_maxof ATM-3507 is 5,758 ng/mL and the the t_1/2is 5.01 h. The observed plasma clearance and volume of distribution at steady state of ATM-3507 is 33.8 mL/min/kg and 7.23 L/kg, respectively^[1].
