| Use | Pirarubicin is an anthracycline. |
| In vitro study | Pirarubicin was rapidly taken up by M5076 cells and reached an intracellular concentration of over 2.5 times that of doxorubicin. Pirarubicin was more effective than doxorubicin in inhibiting 50% of cell growth in vitro. In MG-63 cells, Pirarubicin causes cell cycle arrest at the G0/ G1 phase. In MG-63 cells, Pirarubicin inhibited the expression of PCNA, cyclin D1,cyclin E and Bcl-2, and increased Bax protein expression. In MG-63 cells, Pirarubicin markedly relaxed noradrenaline (0.1 μm)-induced contraction of the endothelial aorta, but had no effect on cells without endothelium. Pirarubicin-induced relaxation was induced by methylene blue (5 μm), hydroquinone (100 μm), phenidone (50 μm), hemoglobin (1 μm) and p-bromobenzoylmethyl bromide (50 μm) but not by indomethacin (25 μm). In SKUT1B,HEC1A and BG1 cell lines, Pirarubicin is about 2-5 times more potent than adriacin. Pirarubicin also showed a reverse dose-response pattern of G2 hindrance, such that at high doses, cell cycle dynamics would mimic those of untreated controls. |
| In vivo study | In mice with M5076 solid tumors, Pirarubicin reduced tumor weight to 60% of control levels, although doxorubicin had no effect. When Pirarubicin and Epirubicin are injected via the hepatic intra-arterial (HIA) route, effective against V × 2 tumors, Pirarubicin is more active than Epirubicin. |
