Doxorubicin (Hydroxydaunorubicin) hydrochloride 是一种具有细胞毒性的蒽环类抗生素，是一种抗癌化疗试剂。Doxorubicin hydrochloride 是一种有效的人类DNA topoisomerase I和topoisomerase II抑制剂，IC50分别为 0.8 μM 和 2.67 μM。Doxorubicin hydrochloride 可降低 AMPK 及其下游靶蛋白乙酰辅酶 A 羧化酶的磷酸化。还可诱导凋亡 (apoptosis) 和自噬。
| 生物活性 | Doxorubicin (Hydroxydaunorubicin) hydrochloride, a cytotoxic anthracyclineantibiotic, is an anti-cancer chemotherapy agent. Doxorubicin hydrochloride is a potent humanDNAtopoisomeraseIandtopoisomeraseIIinhibitor withIC50s of 0.8 μM and 2.67 μM, respectively. Doxorubicin hydrochloride reduces basal phosphorylation ofAMPKand its downstream targetacetyl-CoA carboxylase. Doxorubicin hydrochloride inducesapoptosisandautophagy[1][2][3]. |

体外研究
(In Vitro) | Doxorubicin hydrochloride (1-8 μM; 24 and 48 hours) decreases the viability of MCF-10F, MCF-7 and MDA-MB-231 cells in a time- and dose-dependent manner[4].
Doxorubicin hydrochloride (1 μM; 3 and 24 hours) results in Hct-116 human colon carcinoma cells reduction in G0/G1 phase and accumulation in G2 phase[5].
Doxorubicin hydrochloride (1 μM for MCF-10F and MDA-MB-231 cells, 4 μM for MCF-7 cells; 48 hours) induces apoptosis by upregulating Bax, caspase-8 and caspase-3 and downregulation of Bcl-2 protein expression[4].
Cell Viability Assay[4] | Cell Line: | Breast cancer cell lines MCF-10F, MCF-7 and MDA-MB-231 | | Concentration: | 0, 1, 2, 4 and 8 μM | | Incubation Time: | 24 and 48 hours | | Result: | IC50was 1 μM for both MCF-10F and MDA-MB-231 cell lines.
IC50was 4 μM for MCF-7 cell line. |
Cell Cycle Analysis[5] | Cell Line: | Hct-116 human colon carcinoma cells | | Concentration: | 1 μM | | Incubation Time: | 3 hours and 24 hours | | Result: | Both, bolus (3 h) and continuous (24 h) incubation led to a significant reduction of cells in G0/G1 and accumulation in G2 phase. |
Western Blot Analysis[4] | Cell Line: | Breast cancer cell lines MCF-10F, MCF-7 and MDA-MB-231 | | Concentration: | 1 μM for MCF-10F and MDA-MB-231 cells, 4 μM for MCF-7 cells | | Incubation Time: | 48 hours | | Result: | Bax protein expression was upregulated in MCF-10F and MDA-MB-231 cell lines but MCF-7 cells did not show any significant increase.
Caspase-8 gene expression was upregulated in MCF-10F, but it was downregulated in MCF-7 and MDA-MB-231 cells. |

体内研究
(In Vivo) | Treatment with Doxorubicin (2 mg/kg) or Zoledronic acid (100 μg/kg) alone does not statistically significantly decrease final tumor volume compared with saline. Mice treated with Doxorubicin plus Zoledronic acid have statistically significantly smaller final tumor volumes than those treated with Doxorubicin alone[6].
| Animal Model: | Female MF1 nu/nu mice bearing MDA-G8 breast tumor xenograft (6-week-old)[6] | | Dosage: | Doxorubicin (2 mg/kg); Zoledronic acid (100 μg/kg) | | Administration: | Intravenous injection; once a week; 6 weeks | | Result: | Moderate inhibition of subcutaneous tumor growth in mice that were treated with 2 mg/kg Doxorubicin alone or with 100 μg/kg Zoledronic acid alone compared to the saline control.
Mice treated with Zoledronic acid and Doxorubicin together had statistically significant smaller mean tumor volumes on day 42 than those treated with Doxorubicin alone. |
