(Rac)-RK-682 是 RK-682 的外消旋体。(Rac)-RK-682 是一种蛋白质酪氨酸磷酸酶 (PTPases) 抑制剂。(Rac)-RK-682 抑制蛋白酪氨酸磷酸酶 1B (PTP-1B)、低分子量蛋白酪氨酸磷酸酶 (LMW-PTP)、细胞分裂周期 25B (CDC-25B)，IC50分别为 8.6 μM、12.4 μM 和 0.7 μM。

Pentamidine dimesylate is an inhibitor of calcium-dependent complex formation with p53 [(Ca)S100B-p53) in malignant melanoma (MM). Pentamidine dimesylate restores p53 tumor suppressor activity in vivo.

MY33-3 is a powerful and specific inhibitor of receptor protein tyrosine phosphatase (RPTP)β/ζ, demonstrating an IC50 value of approximately 0.1 μM. Moreover, MY33-3 exhibits inhibitory activity against PTP-1B with an IC50 value of about 0.7 μM. Additionally, MY33-3 has been shown to effectively decrease ethanol consumption and alleviate neuroinflammation and cognitive dysfunction induced by Sevoflurane.
