生物活性
E3330 is a specific inhibitor of AP endonuclease 1 redox domain. E3330 inhibits APE-1 regulation of transcription factors, but does not affect Ape1 DNA repair activity. AP endonuclease 1 (APE1; also known as REF-1) is a multifunctional protein with dual functions in DNA repair and redox regulation of transcription factors. It is involved in apurinic/apyrimidinic endonuclease DNA base excision repair activity, in proofreading exonuclease activity, and in modulating DNA binding activity of several transcription factors including NF-κB, Egr-1, p53, AP-1, CREB, HIF-α, and members of the Pax family. APE1 is overexpressed in several human cancers, and disruption of APE1 function has detrimental effects on cancer cell viability. E3330 significantly reduces the growth of human pancreatic cancer cellsin vitroand inhibits pancreatic cancer cell migration.

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
