Targets
Topo II [1]
In vitro

Pirarubicin is rapidly taken up by M5076 cells and the intracellular concentration of pirarubicin reaches more than 2.5-fold that of doxorubicin. Pirarubicin is more effective than doxorubicin in terms of the 50% cell growth-inhibitory concentration in vitro. [1] Pirarubicin causes G0/G1 cell cycle arrest in MG-63 cells. Pirarubicin suppresses the expression of PCNA, cyclin D1, cyclin E and Bcl-2, and increases Bax expression in MG-63 cells. [2] Pirarubicin markedly relaxes contractions induced by noradrenaline (0.1 μM) in the aorta with endothelium, but not in that without endothelium. Pirarubicin-induced relaxation is inhibited by methylene blue (5 μM), hydroquinone (100 μM), phenidone (50 μM), haemoglobin (1 μM) and p-bromophenacyl bromide (50 μM), but not by indomethacin (25 μM). [3] Pirarubicin is approximately 2-5 times more potent than Adriamycin in SKUT1B, HEC1A, and BG1 cell lines. Pirarubicin also displays a reverse dose-response pattern of G2 block so that at high dose, cell cycle kinetics would mirror those of untreated controls. [4]

In vivo Pirarubicin reduces the tumor weight to 60% of the control level in M5076 solid tumor-bearing mice, although doxorubicin has no effect. [1] Pirarubicin and Epirubicin are effective against V x 2 tumor when injected via the hepatic intra-arterial (h.i.a.) route, the activity of Pirarubicin is stronger than that of Epirubicin. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
