Doxorubicin (Adriamycin) is a Topoisomerase II (Top2) inhibitor with antineoplastic activity.

Doxorubicin hydrochloride (Adriamycin) belongs to the anthracycline class of antibiotics and is an inhibitor of human DNA topoisomerase I/II (IC50=0.8/2.67 μM). Doxorubicin hydrochloride exhibits cytotoxicity and antitumor activity. Doxorubicin hydrochloride reduces the phosphorylation of AMPK and its downstream target protein acetyl coenzyme A carboxylase, and induces apoptosis and autophagy.

Pedaliin 6''-acetate (compound 10), a natural product extracted from Dracocephalum tanguticum, exhibits antioxidative properties and a cytoprotective effect against doxorubicin (DOX)-induced toxicity in H9c2 cardiomyocytes, with an effective concentration (EC50) of 19.1 μM [1].

N-acetyltyramine is a metabolite of the biogenic amine tyramine . It enhances cytotoxicity of doxorubicin in resistant P388 murine leukemia cells with an IC50 value of 0.13 μg/ml compared with an IC50 value of 0.48 μg/ml for doxorubicin alone.

Ladanetin-6-O-β-(6′′-O-acetyl)glucoside, a flavonoid extracted from Dracocephalum tanguticum whole plants, exhibits antioxidant properties and cardioprotective effects, mitigating Doxorubicin-induced toxicity in H9c2 cells [1].

Cimidahurinine can attenuate Doxorubicin (DOX)-induced cardiotoxicity in a dose-dependent manner with EC50 values of 45.79 uM; it protects against cardiotoxicity by decreasing reactive oxygen species (ROS) accumulation and downregulating apoptosis-related Bax/Bcl-2 proteins.

Coleon-U-quinone, a potent P-gp (P-glycoprotein) inhibitor, effectively reduces the viability of cancer cells and increases the sensitivity of multidrug-resistant cancer cells to Doxorubicin [1].

Corilagin has anti-inflammatory activity. Corilagin has a significant antitumour potential and lower toxicity in normal cells in vitro.Corilagin can enhance the cytotoxicity of both cisplatin and doxorubicin on the Hep3B hepatoma cells.Corilagin has antiviral activity, reduces the cytotoxicity induced by EV71 or CA16 on Vero cells with and IC50 value of 5.6 and 32.33 μg/mL, respectively. Corilagin shows the potential to protect against HSV-1-induced encephalitis, and the beneficial effects may be mediated by inhibiting TLR2 signaling pathways.Corilagin has antifibrotics property and is potentiated in treating idiopathic pulmonary fibrosis(IPF), attenuates bleomycin-induced epithelial injury and fibrosis via inactivation of oxidative stress, proinflammatory cytokine release and NF-κB and TGF-β1 signaling. Solvent:Pyridine, Methanol, Ethanol, etc.

Dalbergioidin exhibits tyrosinase inhibitory activity with an IC50 of 20 mM. It shows a melanin biosynthesis inhibition zone in the culture plate of Streptomyces bikiniensis that has commonly been used as an indicator organism. Dalbergioidin protects MC3T3-E1 osteoblastic cells against H2O2-induced cell damage through activation of the PI3K/AKT/SMAD1 pathway, suggests that it may be useful in bone metabolism diseases, particularly osteoporosis. Dalbergioidin also ameliorates doxorubicin-induced renal fibrosis by suppressing the TGF-β signal pathway.

1-Stearoyl-rac-glycerol is a monoacylglycerol that contains stearic acid at the sn-1 position. 1-Stearoyl-rac-glycerol levels are decreased in tumor tissue in a mouse model of azoxymethane-induced colorectal carcinogenesis. 1-Stearoyl-rac-glycerol has been used in the composition of transfersomes for transdermal delivery of doxorubicin in rats, leading to doxorubicin accumulation in lymph nodes, spleen, and heart.

Wallichinine shows inhibitory activity on platelet aggregation caused by platelet activating factor (PAF). Wallichinine with ABCB1 presents valuable clues for the development of novel MDR reversal reagents from natural products, wallichinine can significa

Tetramethylcurcumin is a novel curcumin analog, is an effective inhibitors of STAT3 phosphorylation, DNA binding activity, and transactivation in vitro.it also inhibits colony formation in soft agar, cell invasion, and exhibit synergy with the anti-cancer drug doxorubicin against breast cancer cells.

Visnagin has acute hypotensive, anti-inflammatory, and neuroprotective effects, it protects against doxorubicin-induced cardiomyopathy through modulation of mitochondrial malate dehydrogenase.

Moracin O shows significant neuroprotective, and analgesic activities, it also has a strong protective influence against doxorubicin-induced cardiomyopathy in H9c2 cells with the EC50 value of 4.5 ± 1.3 μM. Moracin O exhibits potent in vitro inhibitory ac
