Yohimbinic acid, also known as yohimbic acid is an indole alkaloid, which was isolated from dried roots of Rauwolfia serpentina. Yohimbinic acid is a potent inhibitor of a human DNA Topoisomerase I and can inhibit cancer cells growth.

Bisphenol A is a small estrogenic monomer that is polymerized to produce polycarbonate plastic and resins used to line metal cans. It is also used to make some dental sealants. Bisphenol A had been considered to be a very weak environmental estrogen. It is able to interact with human estrogen receptors. In addition, it binds strongly to the estrogen-related receptor gamma. Bisphenol A inhibited androgen-induced androgen receptor transcriptional activity. Prenatal exposure to maternal Bisphenol A concentrations were related to higher levels of anxiety, depression, aggression, and hyperactivity in children. Bisphenol A exposure in childhood was associated with higher levels of anxiety, depression, hyperactivity, inattention, and conduct problems. It never found use as a drug.

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.

Endoxifen, also known as N-desmethyl-4-hydroxytamoxifen, is active metabolites of tamoxifen. This metabolite exhibits a 100-fold higher binding affinity to the estrogen receptor (ER) and are more effective in suppressing cell proliferation than tamoxifen. In humans, the conversion from tamoxifen to endoxifen is predominant. Endoxifenis is an orally active, selective estrogen receptor modulator (SERM) that was developed for the treatment of estrogen receptor-positive breast cancer. In addition, this drug possesses antimanic properties, what can be used in the treatment of patients with bipolar I disorder (BPD I).

Racemethorphan is racemic mixture of Dextromethorphan and Levomethorphan. Racemethorphan is listed under the Single Convention on Narcotic Drugs 1961 and is therefore listed in the United States as a Controlled Substance, specifically as a Narcotic in Schedule II. Dextromethorphan is a non-narcotic morphine derivative widely used as an antitussive. Dextromethorphan is a cough suppressant in many over-the-counter cold and cough medicines. In 2010, the FDA approved the combination product dextromethorphan/quinidine for the treatment of pseudobulbar affect. Dextromethorphan suppresses the cough reflex by a direct action on the cough center in the medulla of the brain. Levomethorphan is an opioid analgesic of the morphinan family that has never been marketed.

Gluceptate sodium also known as sodium glucoheptonate (H-Quest A300) is a non-toxic, a non-hazardous chelating agent, which forms stable complexes with di- and trivalent metal ions such as Ca2+, Fe2+, Fe3+, Al3+, etc. This substance is highly compatible with strong alkaline mediums and can prevent the bacterial degradation of the solution. Gluceptate sodium has various applications in water treatment, agricultural, cosmetics, textile processing and in some others fields.

There is a little information around sancycline. It is known, that it was synthesized by Conover and co-workers in 1962 and it was antibacterial compound. It was proposed that sancycline binds to the 30S of bacterial ribosomal subunit and inhibiting protein translation by blocking entry of aminoacyl-tRNA into the ribosome A site.
