Tetroquinone (Tetrahydroxy-1,4-benzoquinone, tetrahydroxy-p-benzoquinone, tetrahydroxybenzoquinone) is cyclohexadiene derivative with four hydroxyl groups and two ketone groups in opposite (para) positions, with potent prooxidant activity. The exposure of exponentially growing cultures to Tetroquinone, in the presence of Ca2+, caused a dose-dependent inhibition of cell growth and DNA synthesis. The chemical reactivity of Tetroquinone is strongly similar to those of physiological polyphenols, such as catechols and catecholamines. Despite their physiological and pharmacological roles, these compounds may, in addition, present toxicological properties due to their ability to autoxidize generating ROS and quinones Similar to catechols, the OH-substituents confer to Tetroquinone the ability to autoxidize readily in neutral aqueous solutions generating intermediate superoxide anion radicals, semiquinone radicals, and the corresponding quinone. The compound can be synthesized from glyoxal or from myo-inositol (phytic acid), a natural compound widely present in plants.

Indium Chloride In-113 is a salt of the only stable Indium isotope with applications in organic synthesis as a Lewis acid. Indium Chloride is the most available soluble derivative of indium with high reproductive toxicity. In in vitro models, Indium Chloride inhibits cell viability by elevating intracellular ROS and inducing apoptosis. In animal models Indium chloride exposure cause the accumulation of indium in blood and lung, bone marrow micronucleus rate increased, the occurrence of oxidative damage and pathological changes. Besides that, the indium chloride exposed showed significant toxicity to sperm function, as well as an increased percentage of sperm morphological abnormality and chromatin DNA damage.

Tesofensine (also known as NS-2330) is a novel triple monoamine reuptake inhibitor with intrinsic inhibitory activity on norepinephrine (NE), serotonin (5-HT), and dopamine (DA) transporter function. It was development by NeuroSearch as a potential therapy for Alzheimer's disease (AD) and Parkinson's diseases, but these efforts have been discontinued. In phase II clinical trials with tesofensine in obese individuals, dose-related reductions in body weight, body fat and waist circumference, as well as improvements in other obesity-related endocrine factors were observed and the FDA recently endorsed the phase III trial program for this agent.

Rocastine (AHR-11325) is a potent, nonsedating antihistamine with a rapid onset of action. This H1-antagonist effectively protected guinea pigs challenged with a lethal dose of histamine. It has also been mentioned in patents as a candidate to treat eye conditions and cough/cold mixtures (in which the lack of sedative effects from a non-sedating antihistamine would be especially useful in children, because daytime sedation is especially undesirable in this group). However, information on current use is not available and other second-generation, non-sedative antihistamines are available.

Cethexonium is a cyclohexanols derivative with antimicrobial activities.

2,4-Diaminophenol dihydrochloride is used in the manufacture of dyes and as a color accelerator in photographic developers. 2,4-Diaminophenol is an ingredient of hair dyes and colors. 2,4-Diaminophenol and 2,4-Diaminophenol Dihydrochloride are considered safe for use in hair dyes at concentrations up to 0.2% (as the free base). 2,4-Diaminophenol Dihydrochloride is approved for use in Japan in cosmetic.
