Biological Activity of Doxorubicin (Adriamycin) HCl

DescriptionAntitumor antibiotic agent that inhibits DNA topoisomerase II. DNA intercalator that inhibits nucleic acid synthesis and induces apoptosis. Reduces intracellular tau levels.

Protocol

Cell experiment: [1]

Cell lines

H9c2 cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reacting condition

1 μg/ml, 2 hours

Applications

H9c2 cells were treated with increased concentrations of Doxorubicin (0.1, 0.3, 0.5, and 1.0 μg/ml, equal to 0.17, 0.52, 0.85, and 1.71 μM separately) for 2 h, or treated with 0.3 μg/ml (equal to 0.52 μM) of Doxorubicin for the different time points. Doxorubicin induces strong AMPKα (Thr 172) and its downstream Acetyl-CoA carboxylase (ACC, Ser 79) phosphorylation in both time- and dose-dependent manner. AMPKα phosphorylation became obvious after 1 h of Doxorubicin treatment which was further sustained for at least 6 h. LKB1, the possible upstream kinase for AMPK, was also activated by Doxorubicin in H9c2 cells.

Animal experiment: [2]

Animal models

C57BL/10 mice

Dosage form

Intraperitoneal injection, 20 mg/kg

Application

Five days after doxorubicin injection, mice displayed significantly impaired systolic (LVP, -29%; dP/dtmax, -45%), diastolic (dP/dtmin, -44%; stiffness, +275%), and global (SV, -61%; HR, -18%; CO,-68%) left ventricular (LV) function when compared with the placebo group. Both cardiac lipid peroxidation activity (+37%) and cardiac nitrotyrosine protein expression (+204%) were increased when compared with placebo mice.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background on Doxorubicin (Adriamycin) HCl

Doxorubicin is a semi-synthesized anticancer agent derived from bacterial culture. [1] It is an anthracycline antibiotic. It is been widely used in blood cancers, solid tumors and sarcomas.

Doxorubicin intercalates into DNA double strand and inhibits the progression of DNA topoisomerase II, stopping replication process. [2] Doxorubicin also induces histone eviction from open chromatin, causing DNA damage and epigenetic deregulation. [3]

Doxorubicin is administrated intravenously. Approximately 75% of doxorubicin and its metabolites bind to plasma protein. Doxorubicin does not cross blood brain barrier. 50% of the drug is eliminated unchanged from the body mainly though bile excretion. The remaining undergoes one-electron reduction, two-electron reduction, and deglycosidation. The major metabolite is a potent membrane ion pump inhibitor, which is associated with cardiomyopathy. [4]

The effects of adriamycin (doxorubicin HCl) on human red blood cells.[Pubmed:6254923]

Hemoglobin. 1980;4(5-6):735-45.

We have studied the effects of adriamycin (doxorubicin HCl) on human red blood cells. The peroxidizing effect of adriamycin on the thiols of red cell constituents resulted in decreased glutathione stability, and oxidation of hemoglobin and membrane protein components 1, 2, and 3, forming large molecular weight complexes. Membrane lipids were also peroxidized. Adriamycin itself did not inhibit the enzymes of the reductions system (glucose-6-phosphate dehydrogenase, 6-phosphogluconic dehydrogenase, glutathione reductase, glutathione peroxidase, catalase, superoxide dismutase) of the red cells. Because adriamycin has the potential of inhibiting ATPase, including both Na-K-dependent ATPase and ouabain insensitive ATPase, at concentrations not inhibitory to other enzymes, the net sodium content increased, and potassium content decreased after incubation of red cells with adriamycin at high concentrations. The experimental results described with adriamycin may serve as a model for the possible mechanism of cardiotoxicity observed in its clinical use, and also explain the potential hemolyzing effect on red cells. There was greater oxidizing effect on glucose-6-phosphate dehydrogenase (G-6-PD) deficient than on normal erythrocytes. It is suggested that adriamycin be used with caution in individuals with G-6-PD deficient red cells.

In vitro release, pharmacokinetic and tissue distribution studies of doxorubicin hydrochloride (Adriamycin HCl) encapsulated in lipiodolized w/o emulsions and w/o/w multiple emulsions.[Pubmed:1409841]

Pharmazie. 1992 Jun;47(6):439-43.

The lipiodolized w/o emulsion or w/o/w multiple emulsion containing Doxorubicin hydrochloride (1; Adriamycin HCl) with different emulsifiers was prepared to evaluate in vitro sustained-release behavior, pharmacokinetic and tissue distribution function in Sprague Dawley (SD) rats. The results of dissolution indicate that the release of 1 was significantly sustained for both emulsions when HCO-60 (polyoxyethylene (60) hydrogenated castor oil) was used as an emulsifier. The serum concentration of 1 was reduced and prolonged for both emulsions with the increase of HCO-60. The C(max) level was lowered and T(max) value was delayed after administration of w/o emulsions with higher HCO-60 concentration. The apparent terminal half-life for 1 released from some emulsions with higher concentration of HCO-60 was 3-folds higher than that of the 1 solution. The clearance of some w/o or w/o/w ADR emulsions also decreased with the increase of HCO-60. Not only the concentration of 1 in heart and kidney decreased significantly after the administration of w/o emulsions with the higher concentration of HCO-60, but also the hepatic concentration of 1 was higher and increased with HCO-60 concentration. The hepatic 1 level became lower after administration of w/o/w multiple emulsions with the increase of HCO-60; however, the concentration of 1 in heart, lung and spleen increased somewhat. The results indicate that lipiodol and HCO-60 seemed to play an important role in the prolongation and selective retention of w/o emulsion or w/o/w multiple emulsion, in vitro and in vivo.

Pharmacologic reductions of total tau levels; implications for the role of microtubule dynamics in regulating tau expression.[Pubmed:16930453]

Mol Neurodegener. 2006 Jul 26;1:6.

UNLABELLED: The microtubule-associated protein tau (MAPT) is a pathological component of several neurodegenerative diseases and clinical dementias. Here, we have investigated the effects of a series of commercially available FDA-approved compounds and natural products on total tau protein levels using a cell-based approach that allows for the rapid and efficient measurement of changes in protein expression. RESULTS: The compounds that reduced tau largely fell within 3 functional categories with the largest percentage being microtubule regulators. Several of these candidates were validated in both a human neuroglioma and a human neuroblastoma cell line. While these drugs lead to a rapid reduction in tau protein levels, a selective decrease in MAPT mRNA expression was also observed. CONCLUSION: These findings suggest that the identified compounds that reduce tau levels may act either through direct effects on the MAPT promoter itself or by altering a feedback transcriptional mechanism regulating MAPT transcription. This is particularly interesting in light of recent evidence suggesting that MAPT 5' UTR mutations in late-onset PD and PSP cases alter the expression of tau mRNA. In fact, one of the compounds we identified, rotenone, has been used extensively to model PD in rodents. These observations may provide key insights into the mechanism of tau turnover within the neuron while also providing the first evidence that selectively reducing tau protein levels may be possible using compounds that are FDA-approved for other uses.

A critical evaluation of the mechanisms of action proposed for the antitumor effects of the anthracycline antibiotics adriamycin and daunorubicin.[Pubmed:10075079]

Biochem Pharmacol. 1999 Apr 1;57(7):727-41.

The mechanisms responsible for the antiproliferative and cytotoxic effects of the anthracycline antibiotics doxorubicin (Adriamycin) and daunorubicin (daunomycin) have been the subject of considerable controversy. This commentary addresses the potential role of DNA synthesis inhibition, free radical formation and lipid peroxidation, DNA binding and alkylation, DNA cross-linking, interference with DNA strand separation and helicase activity, direct membrane effects, and the initiation of DNA damage via the inhibition of topoisomerase II in the interaction of these drugs with the tumor cell. One premise underlying this analysis is that only studies utilizing drug concentrations that reflect the plasma levels in the patient after either bolus administration or continuous infusion are considered to reflect the basis for drug action in the clinic. The role of free radicals in anthracycline cardiotoxicity is also discussed.

Identification of yeast DNA topoisomerase II mutants resistant to the antitumor drug doxorubicin: implications for the mechanisms of doxorubicin action and cytotoxicity.[Pubmed:9380029]

Mol Pharmacol. 1997 Oct;52(4):658-66.

Doxorubicin is a therapeutically useful anticancer drug that exerts multiple biological effects. Its antitumor and cardiotoxic properties have been ascribed to anthracycline-mediated free radical damage to DNA and membranes. Evidence for this idea comes in part from the selection by doxorubicin from stationary phase yeast cells of mutants (petites) deficient in mitochondrial respiration and therefore defective in free radical generation. However, doxorubicin also binds to DNA topoisomerase II, converting the enzyme into a DNA damaging agent through the trapping of a covalent enzyme-DNA complex termed the 'cleavable complex.' We have used yeast to determine whether stabilization of cleavable complexes plays a role in doxorubicin action and cytotoxicity. A plasmid-borne yeast TOP2 gene was mutagenized with hydroxylamine and used to transform drug-permeable yeast strain JN394t2-4, which carries a temperature-sensitive top2-4 mutation in its chromosomal TOP2 gene. Selection in growth medium at the nonpermissive temperature of 35 degrees in the presence of doxorubicin resulted in the isolation of plasmid-borne top2 mutants specifying functional doxorubicin-resistant DNA topoisomerase II. Single-point changes of Gly748 to Glu or Ala642 to Ser in yeast topoisomerase II, which lie in and adjacent to the CAP-like DNA binding domain, respectively, were identified as responsible for resistance to doxorubicin, implicating these regions in drug action. None of the mutants selected in JN394t2-4, which has a rad52 defect in double-strand DNA break repair, was respiration-deficient. We conclude that topoisomerase II is an intracellular target for doxorubicin and that the genetic background and/or cell proliferation status can determine the relative importance of topoisomerase II- versus free radical-killing.

Studies on the in vitro reactivity of clofibryl and fenofibryl glucuronides. Evidence for protein binding via a Schiff's base mechanism.[Pubmed:8347161]

Biochem Pharmacol. 1993 Aug 3;46(3):357-64.

Clofibryl and fenofibryl acyl (ester) glucuronides (CAG and FAG) are major metabolites in humans of the hypolipidaemic drugs clofibrate and fenofibrate, respectively. We have investigated three inter-related aspects of the reactivity of CAG and FAG in human serum albumin (HSA) solution, human plasma and in buffer at pH 7.0: namely (a) rearrangement via acyl migration to glucuronic acid esters of clofibric acid (CA) and fenofibric acid (FA), (b) hydrolysis of the parent glucuronide and rearrangement products to yield CA and FA and (c) the formation of covalent adducts with albumin and plasma protein. CAG was more reactive than FAG in all media, especially the protein solutions. The reactivity of both glucuronides was accelerated in protein solution compared with buffer and this was more marked in plasma than in HSA solution. The predominant reaction during the initial stages of the incubation was formation of isomeric rearrangement products. In the protein solutions, CA and FA were the major reaction products after 24 hr, compared to the rearranged isomers in buffer. Protein binding of 14C to HSA was markedly higher after incubation of CAG and FAG labelled on the glucuronyl moiety compared with the label on the aglycone. This is consistent with the covalent binding of CAG and FAG to protein proceeding via the formation of a Schiff's base rather than by transacylation.
