Introduction of 29767-20-2 :
Teniposide is a podophyllotoxin derivative, acts as a topoisomerase II inhibitor, and used as a chemotherapeutic agent. IC50 & Target: Topoisomerase II[2] In Vitro: Teniposide is a topoisomerase II inhibitor. Teniposide (VM-26, 0.15-45 mg/L) inhibits the proliferation of Tca8113 cells in a dose-dependent manner, with an IC50 of 0.35 mg/L. Teniposide (5 mg/L) induces apoptosis of Tca8113 cells. Teniposide (5.0 mg/L) causes cell arrested at G2/M phase in Tca8113 cells[2]. Teniposide is active on primary cultured glioma cells from patients, when the level of miR-181b is high in the cells, with an IC50 of 1.3 ± 0.34 μg/mL. Cells treated with teniposide with low MDM2 have decreased viability compared with control cells, and the IC50 decreases from 5.86 ± 0.36 μg/mL to 2.90 ± 0.35 μg/mL upon MDM2 suppression. Teniposide also inhibits the viability of glioma cell with high level of miR-181b, through mediation of MDM2[3]. In Vivo: Teniposide (0.5 mg/kg, i.p.) significantly increases micronucleated polychromatic erythrocyte (MNPCE) frequencies, which is directly related to bone marrow toxicity as significant suppression of bone marrow is noted. Teniposide (24 mg/kg, i.p.) markedly decreases the frequencies of BrdU-labelled sperm. Teniposide (12, 24 mg/kg, i.p.) also dramatically induces disomic sperm in the germ cell of male mice[1].
