Quinone
Quinone is also called 1,4-benzoquinone or cyclohexadienedione. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity. Derivatives of quinones are common constituents of biologically relevant molecules. Some serve as electron acceptors in electron transport chains such as those in photosynthesis (plastoquinone, phylloquinone), and aerobic respiration (ubiquinone). Quinone is a common constituent of biologically relevant molecules (e.g. Vitamin K1 is phylloquinone). A natural example of quinones as oxidizing agents is the spray of bombardier beetles. Hydroquinone is reacted with hydrogen peroxide to produce a fiery blast of steam, a strong deterent in the animal world. 1,4-Benzoquinone, commonly known as para-quinone or quinone, is a chemical compound with the formula C6H4O2. 1,4-Benzoquinone is found in barley, olive, and anise.

Embelin
Embelin (Embelic acid), a potent, nonpeptidic XIAP inhibitor (IC50=4.1 μM), inhibits cell growth, induces apoptosis, and activates caspase-9 in prostate cancer cells with high levels of XIAP. Embelin blocks NF-kappaB signaling pathway leading to suppression of NF-kappaB-regulated antiapoptotic and metastatic gene products. Embelin also induces autophagic and apoptotic cell death in human oral squamous cell carcinoma cells[1][2][3].

5-O-Methylembelin
5-O-Methylembelin is a constituent of Myrsine africana (cape myrtle). Constituent of Myrsine africana (cape myrtle) 5-O-Methylembelin is a natural isocoumarin that inhibits PCSK9, inducible degrader of the low-density lipoprotein receptor (IDLR), and sterol regulatory element binding protein 2 (SREBP2) mRNA expression[1].
Rapanone
Rapanone is a member of dihydroxy-1,4-benzoquinones. Rapanone is a natural product found in Badula barthesia, Ardisia crenata, and other organisms with data available. Rapanone is a natural benzoquinone. Rapanone exhibits a broad spectrum of biological actions, including anti-tumor, antioxidant, anti-inflammatory, antibacterial and antiparasitic.

Embelin
Embelin is a member of the class of dihydroxy-1,4-benzoquinones that is 2,5-dihydroxy-1,4-benzoquinone which is substituted by an undecyl group at position 3. Isolated from Lysimachia punctata and Embelia ribes, it exhibits antimicrobial, antineoplastic and inhibitory activity towards hepatitis C protease. It has a role as a hepatitis C protease inhibitor, an antimicrobial agent, an antineoplastic agent and a plant metabolite.
