摩爾計算器

Topotecan (SKF 104864; NSC 609669) 是一種口服有效的拓撲異構酶 I (Topoisomerase I) 抑制劑。Topotecan 誘導細胞周期阻滯在 G0/G1 和 S 期，促進凋亡 (apoptosis)。Topotecan 具有抗癌活性。

在相同的摩爾濃度下，化合物鹽形式與游離形式有相同的生物活性，但鹽形式 Topotecan hydrochloride 通常具有更好的水溶性和穩(wěn)定性。

體外研究
(In Vitro)

Topotecan obviously inhibits proliferation of human glioma cells and glioma stem cells (GSCs) in a dose- and time-dependent manner^[1].
Topotecan (0-40 μM) obviously inhibits the cell viability compared with the control groups, in a dose-dependent manner^[1].
Topotecan shows anti-proliferation activity against U251, U87, GSCs-U251 and GSCs-U87 cells, with IC₅₀ values of 2.73±0.25, 2.95±0.23, 5.46±0.41, and 5.95±0.24 μM, respectively^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

NUB-7 metastatic model, the animals belonging to all the 4 groups are sacrificed after 14 days treatment. Compared with the control, Low dose metronomic (LDM) Topotecan (TP) and TP+Pazopanib (PZ) liver weights are significantly lower in TP+PZ-treated animals, compared with PZ. Microscopic tumors are visible in the livers of mice belonging to all the groups except TP+PZ confirming the ability of TP+PZ to control liver metastasis^[2].
Topotecan (0.5, 1.0, and 1.5 mg/kg; Orally, daily) causes greater reduction in microvascular density in an ovarian cancer model, but the mice treated with 1.5 mg/kg daily, oral Topotecan show decreased food intake, and a lesser antitumor effect^[2].

Cell Assay ^[1]	The U251, U87, GSCs-U251 and GSCs-U87 cells are seeded at a density of 2×10⁴ cells per well in 96-well plates separately, and incubated for 24 h. Cells are administered with Shikonin and Topotecan (0.02, 0.2, 2, 20, 40 μM). After the treatment, 10 μL of cell counting kit-8 (CCK-8) is added into each well for additional 1-hour incubation at 37°C. The optical density (OD) is read with a microplate reader at 450 nm^[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration ^[2]	Mice^[2] For subcutaneous xenograft studies, we used SK-N-BE, SH-SY5Y, KHOS, and RH30. 1×10⁶ cells are implanted subcutaneously into the inguinal fat pad of each of nonobese diabetic/severe combined immune deficient (NOD/SCID) mice. When tumors reached 0.5 cm in diameter, the animals are randomized into 4 groups and treated daily by oral gavage. The animals are grouped as: Control group, LDM Topotecan group or LDM TP (1 mg/kg Topotecan), Pazopanib group or PZ (150 mg/kg Pazopanib) and combination group or TP+PZ (1 mg/kg Topotecan+150 mg/kg Pazopanib). To compare pulse Topotecan with LDM TP in KHOS osteosarcoma model, PZ is replaced by weekly oral dose of pulse Topotecan (SKF104864) or Pulse TP (15 mg/kg Topotecan (SKF104864)). The criteria for endpoint are tumor sizes exceeding 2.0 cm in diameter or animals showing signs of morbidity. The tumor sizes are measured on a daily basis until the endpoint or sacrifice. The long (D) and short diameters (d) are measured with calipers. Tumor volume (cm³) is calculated as V=0.5×D×d². When the endpoint is reached or at the end of the treatment, the animals are sacrificed by cervical dislocation. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
