Apart from the abovementioned organic materials, the biomolecule-based materials are also promising selections to be used as anodes for SIBs. For these biomolecule-based organic materials, the quinine and carbonyl groups are included.260–264 Chen’s group reported that the juglone-typed biomolecule-based organic compound showed outstanding electrochemical performance when used as an anode for SIBs, because the redox quinine carbonyl functional groups inside (Figure 3.20e and f).261 Furthermore, the juglone also showed further improved performance when embedded on the surface of rGO sheets due to the strong chemical interaction between the graphene and aromatic functional groups. Therefore, this composite showed a high reversible capacity of over 300 mAh g−1 and outstanding cycling life.

The toxicity of Fe(II) and Fe(III) complexes of lawsone and juglone (1) to rat hepatocytes has been observed. All the complexes exhibit cytotoxic properties depending upon the dosage. The complexes were more cytotoxic than the naphthoquinone ligands. The intracellular levels of glutathione (GSH) were evaluated with an assumption that the oxidation of GSH might be related with redox couple of naphthoquinones. The results reveal that the toxicity is facilitated by the interaction with glutathione which leads to oxidative stress [31]. The cytotoxic studies were carried out for the copper complex of lawsone using tobacco BY-2 as the model, which could be compared to the HeLA cells. From the studies, it was inferred that in lower concentrations, the complex was able to generate signals leading to programmed cell death and at high concentrations, there was rapid cell death [33]. The zinc, cobalt, copper and nickel complexes of lawsone (1) were investigated for their cytotoxicity towards human colorectal adenocarcinoma (HT-29), hepatocellular carcinoma (HepG2) and cervical adenocarcinoma cells (HeLa). Copper complex exhibited the highest cytotoxicity. The induction of apoptosis was proposed to occur via activation of caspase [35]. The cobalt, nickel, copper and zinc Schiff base complexes with lawsone as the coligand (13) were studied for cytotoxicity on laboratory-cultured Artemia nauplii brine shrimp. Copper complex possessed the highest activity among all the complexes [53].
