Product Introduction

Bioactivity
Description
Pirarubicin (Theprubicin) is an anthracycline antibiotic. It is also a DNA/RNA synthesis inhibitor that intercalates into DNA and interacts with topoisomerase II, utilized as an antineoplastic agent.
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]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
