Biological Activity

Topotecan hydrochloride (trade name Hycamtin) is a potent antineoplastic agent. It is a water soluble analog of the alkaloid camptothecin that potently inhibits DNA topoisomerase I. Topotecan hydrochloride induces rapid apoptotic death in human B-lineage acute lymphoblastic leukemia (ALL) cells with IC50 values of 33 nM and 0.28 μM, respectively. Topotecan improves survival in three mouse models of poor prognosis ALL and downregulates B-Myb and MycN expression in neuroblastoma cells. Topotecan demonstrates a broad spectrum of antitumor activity against a variety of other tumors including ovarian cancer, cervical cancer, neuroblastoma, brainstem glioma, and Ewing’s sarcoma.

Results MiR-3163 plays important roles in multidrug resistance (Table 1, Fig. 5A). Results showed that when miR-3163 was overexpressed in RCSCs, the ATPase activity of ABCG2 was significantly downregulated compared to RCSCs with Scramble (Fig. 5B).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
