生物活性

Camptothecin (CPT), a kind of alkaloid, is a DNA topoisomerase I (Topo I) inhibitor with an IC₅₀ of 679 nM. Camptothecin (CPT) exhibits powerful antineoplastic activity against colorectal, breast, lung and ovarian cancers, modulates hypoxia-inducible factor-1α (HIF-1α) activity by changing microRNAs (miRNA) expression patterns in human cancer cells.

体外研究

High TOP1 enzymatic activity MCF7 (Luminal subtype) and HCC1419 (HER2 subtype) show high sensitivity toward Camptothecin (0.1 μM to 5 μM; 72 hours) treatment, exhibiting the IC₅₀ values of 0.089 μM and 0.067 μM, respectively.
Camptothecin (0.5 μM; 6 and 24 hours) reduces desferrioxamine-activated VEGF expression.
Camptothecin (0.5 μM; 8 to 24 hours) strongly prevents the desferrioxamine-dependent HIF-1a accumulation.

Cell Viability Assay

Cell Line:	MCF7 (Luminal subtype) and HCC1419 (HER2 subtype)
Concentration:	0.1 μM to 5 μM
Incubation Time:	72 hours
Result:	High TOP1 enzymatic activity MCF7 (Luminal subtype) and HCC1419 (HER2 subtype) show high sensitivity toward CPT (0.1 μM to 5 μM; 72 hours) treatment, exhibiting the IC₅₀ values of 0.089 μM and 0.067 μM, respectively.

RT-PCR

Cell Line:	HeLa and HEK293 cell lines
Concentration:	0.5 μmol/L
Incubation Time:	6 and 24 hours
Result:	Reduces desferrioxamine-activated VEGF expression in both cell lines after 6 and 24 hours of treatment, whereas in normoxic condition camptothecin does not affect the VEGF mRNA level.

Western Blot Analysis

Cell Line:	HeLa and HEK293 cell lines
Concentration:	0.5 μmol/L
Incubation Time:	8 to 24 hours
Result:	Strongly prevents the desferrioxamine-dependent HIF-1a accumulation after 8 to 24 hours, whereas it does not affect HIF-1b levels.

体内研究

Camptothecin (2 mg/kg every other day) treats mice, has developed numerous pulmonary metastases.
Treatment with both kinase inhibitor of nuclear factor-kappaB-1 (KINK-1) and Camptothecin led to a statistically significant reduction in the number of pulmonary metastases.

Animal Model:	C57BL6 mice (injected with B16F10 melanoma cells)
Dosage:	2 mg/kg
Administration:	every other day, after 19 days
Result:	Has developed numerous pulmonary metastases.

计算结果:

工作液浓度： mg/ml；

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，注：如该浓度超过该批次药物DMSO溶解度，请先联系客服）；

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH₂O，混匀澄清。

配置后的溶液总体积：

注意：1. 首先保证母液是澄清的；
2. 一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
