Etoposide phosphate disodium (BMY-40481 disodium), a phosphate ester prodrug of etoposide, functions as a potent chemotherapeutic agent by selectively inhibiting topoisomerase II, hindering the re-ligation of DNA strands. It is regarded as the active equivalent of etoposide, effectively inducing cell cycle arrest, apoptosis, and autophagy in cancer cells.
Etoposide (Standard) 是一种可用于分析的标准物质,通常用作 Etoposide 的研究和分析中参考的标准样品。Etoposide (VP-16-213) 是一种拓扑异构酶 II 的抑制剂,通过与拓扑异构酶 II 和 DNA 形成复合物来抑制 DNA 合成 (IC50=60.3 μM)。Etoposide 具有抗肿瘤活性,可以诱导细胞凋亡、自噬。
ProTAME is an inhibitor of APC/CFzr and APC/CCdc20. Combinations of proTAME with topoisomerase inhibitors, doxorubicin and etoposide, significantly increase cell death in primary cells and Multiple Myeloma (MM) cell lines, particularly if TOPIIα levels are first increased through pre-treatment with ProTAME.This compound is unstable in powder form and other related salt forms are recommended.
MS-073 (CP-162398) is a P-glycoprotein inhibitor (P-gp). The in vitro resistance to vincristine (VCR) was almost completely reversed in VCR-resistant P388 cells, and the resistance of VCR, adriamycin (ADM), etoposide, and actinomycin D in ADM-resistant hu
NSC 660028 is a novel γ-lactone ring modified arylamino etoposide analogram with strong antitumor activity as an inhibitor of human DNA topoisomerase II.
10'-Desmethoxystreptonigrin is an antibiotic originally isolated from Streptomyces and a derivative of the antibiotic streptonigrin. It is active against a variety of bacteria, including S. aureus, S. faecalis, E. coli, K. pneumoniae, and P. vulgaris (MICs = 0.4, 1.6, 3.1, 3.1 and 0.4 μg/ml, respectively). 10'-Desmethoxystreptonigrin is cytotoxic to HCT116 colon and A2780 ovarian cancer cells (IC50s = 0.004 and 0.001 μg/ml, respectively), as well as HCT116 cells resistant to etoposide and teniposide and cisplatin-resistant A2780 cells (IC50s = 0.003, 0.001, and 0.01 μg/ml, respectively). 10'-Desmethoxystreptonigrin is also an inhibitor of p21ras farnesylation (IC50 = 21 nM).
Potent Chk2 inhibitor (IC50 = 3 nM). Shows >63-fold selectivity for Chk1 over Chk2 and a panel of 84 other kinases. Inhibits Chk2 activation in response to etoposide-induced DNA damage in HT29 cells. Blocks ionizing radiation-induced apoptosis of mouse thymocytes.
