ARN-21934 是一种有效的，高选择性的，具有血脑屏障 (BBB) 通透性的人拓扑异构酶 II α (human topoisomerase II α) 的抑制剂。与抗癌试剂依托泊苷 (Etoposide; IC₅₀=120 μM) 相比，ARN-21934 抑制 DNA 松弛的 IC₅₀ 为 2 μM。ARN-21934 具有良好的体内药代动力学特性，是一种很有前途的抗癌先导化合物。

ARN-21934 is a potent, highly selective, blood-brain barrier (BBB) penetrant inhibitor for human topoisomerase II α over β. ARN-21934 inhibits DNA relaxation with an IC 50 of 2 μM as compared to the anticancer agent Etoposide (IC 50 =120 μM). ARN-21934 exhibits a favorable in vivo pharmacokinetic profile and is a promising lead compound for anticancer research.

ARN-21934 display a different affinity for topoIIα and topoIIβ. ARN-21934 is more potent against the α isoform, the IC50 value for the inhibition of DNA relaxation by topoIIα is 2 μM, the value for inhibition of DNA relaxation by topoIIβ is 120 μM.
ARN-21934 exhibits a small panel of human cancer cell lines. It against melanoma (A375 and G-361), breast (MCF7), endometrial (HeLa), lung (A549), and androgen-independent prostate (DU145) cancer cells with IC50 values of 12.6 μM, 8.1 μM, 15.8 μM, 38.2 μM, 17.1 μM, and 11.5 μM, respectively.
has not independently confirmed the accuracy of these methods. They are for reference only.

ARN-21934 (intraperitoneal injection; 10 mg/kg; single dose) reaches a maximal plasma concentration of 0.68 μg/mL after 15 min. The half-life is 149 min in circulation, still being present in plasma 360 min after injection. The compound also exhibits good clearance values (0.116 L/(min kg)). Besides, ARN-21934 is able to reach the brain, with a maximum concentration of compound at 60 min, and is still present in the brain 360 min after injection has not independently confirmed the accuracy of these methods.
