Doxorubicin hydrochloride is an anthracycline antibiotic with cytotoxic and antitumor activity. It is an effective inhibitor of human DNA topoisomerase I and II, with IC50 values of 0.8 μM and 2.67 μM, respectively. In addition to inhibiting DNA topoisomerases, it can reduce the phosphorylation of AMPK and its downstream target, acetyl-CoA carboxylase. Doxorubicin hydrochloride also induces apoptosis and autophagy. In animal studies, it is commonly used to induce models of acute renal failure, chronic kidney injury, and heart failure.

Demeclocycline (Declostatin) is a tetracycline antibiotic produced by a strain of Streptomyces aureofaciens.Demeclocycline has antimicrobial activity and inhibits the action of vasopressin on the renal tubules, leading to diuresis. Demeclocycline can be used to induce diuresis and acute renal failure.

Plumbagin (Plumbaein) is a yellow dye, formally derived from naphthoquinone. It is named after the plant genus Plumbago, from which it was originally isolated. It is also commonly found in the carnivorous plant genera Drosera and Nepenthes. It is also a component of the black walnut drupe.

Ubiquinone-1 (UQ-1) is an intermediate in the biosynthesis of coenzyme Q, an essential coenzyme in the body's redox reactions, involved in multiple oxidation-reduction processes.

Geldanamycin, an HSP90 inhibitor (Kd: 1.2 μM), specifically disrupts glucocorticoid receptor (GR)/HSP association.

Mitoxantrone (mitozantrone) is an anthracenedione antibiotic with antineoplastic activity. Mitoxantrone intercalates into and crosslinks DNA, thereby disrupting DNA and RNA replication. This agent also binds to topoisomerase II, resulting in DNA strand breaks and inhibition of DNA repair. Mitoxantrone is less cardiotoxic compared to doxorubicin.

Coenzyme Q9 (Ubiquinone 9) (CoQ9) is a normal constituent of human plasma. CoQ9 in human plasma may originate as a product of incomplete CoQ10 biosynthesis or from the diet.

1. Deoxyshikonin (Arnebin 7) may be a new drug candidate for wound healing and treatment of lymphatic diseases. 2. Deoxyshikonin enhances the ability of human dermal lymphatic microvascular endothelial cells (HMVEC-dLy) to undergo time-dependent in vitro cord formation. 3. Deoxyshikonin and dodecyl gallate show significantly synergic antimicrobial activity with penicillin in vivo and in vitro, and can effectively reduce nasopharyngeal and lung colonization caused by different penicillin-resistant pneumococcal serotypes.

Sennoside B is an anthranoid. Anthranoid derivatives are used all over the world as a treatment for constipation.

Menadione (Vitamin K3) is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo.

Mitoxantrone dihydrochloride (NSC-301739) is the hydrochloride salt of an anthracenedione antibiotic with antineoplastic activity. It is a type II topoisomerase inhibitor.

Deoxylapachol has anti-wood rot activity, it can inhibit the brown rot fungi Gloeophyllum sepiarium CBS 353.74 and Gloeophyllum trabeum CBS 318.50 and the white rot fungi Merulius tremellosus CBS 280.73 and Phlebia brevispora CBS 509.92. It also can induc

Beta-Hydroxyisovalerylshikonin is an inhibitor of protein-tyrosine kinases such as v-Src and EGFR, and has been shown to induce apoptosis in several human tumor cell lines. Beta-Hydroxyisovalerylshikonin significantly decreased viability of HCT116 cells (IC50 values = 30.9 μg/mL).

Physcion (Parietin) exhibits laxative, hepatoprotective, anti-inflammatory, anti-microbial, anti-proliferative and anti-tumor effects.

Vitamin K1 (Phylloquinone) a fat-soluble, naturally occurring vitamin with antihemorrhagic and prothrombogenic activity.

β,β-Dimethylacrylalkannin is a natural product isolated from Arnebia nobilis Reichb.f, increases collagen and involucrin content in skin cells.

Primin is a natural product stored in trichomes on the leaves and stems of Primula obconica, exhibiting antimycobacterial and strong antineoplastic actions.

Rhein (NSC 38629) is an anthraquinone compound extracted from Polygonaceae Rheum Officinale with anti-inflammation and antitumor activities.
