MK-467 (also known as Vatinoxan) is a peripheral α2 -adrenoceptor antagonist patented by American multinational pharmaceutical company Merck & Co., Inc. for treatment of hypertension, diabetes, obesity, and as blood platelet aggregation. In preclinical models Vatinoxan administration alleviate the unwanted cardiopulmonary effects of various α2-agonists (such as bradycardia, vasoconstriction, and hypoxemia). Because of its low lipophilicity MK-467 poorly penetrates the mammalian central nervous system and preserve the centrally mediated desired effects of α2-agonists. Simultaneous intramuscular injection of MK-467 hastened the absorption of α2-agonist drugs, which was manifested by rapid onset of sedation.

Thioglycolic acid (TGA, also known as MERCAPTOACETIC ACID) is widely used in the hairdressing industry, which mostly caters to women. TGA has been reported to impair several organs, especially reproductive ones such as testes and ovaries. Thioglycolates (the salt forms of TGA) was shown to penetrate the skin and distribute to the kidneys, lungs, small intestine, and spleen; excretion is primarily in the urine. In addition, thioglycolates can be skin irritants of an animal and can be sensitizers.

Retinal, All-trans is one of the forms of vitamin A. It is an isomer of 11-cis-retinal, transductor of light into the neural signals. Retinal, All-trans is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinal, All-trans is associated with one of the two isoforms of cellular retinol-binding proteins (CRBP-I and CRBP-II). These proteins play important roles in retinoid biology and regulation of the metabolism of retinol and retinal.

Cytisine ( aka baptitoxine and sophorine) is a naturally occurring alkaloid that can be found in several plant genera, such as Laburnum and Cytisus of the family Fabaceae. It has been found to be clinically superior to nicotine replacement therapy for the cessation of smoking. It is available in Eastern Europe under the brand names Tabex and Desmoxan and in Canada under the brand name Cravv. However certain undesirable side effects exist, Cytisine can interfere with breathing and cause death (LD50 i.v., in mice, is about 2 mg/kg) and Cytisine is also teratogenic. Cytosine is an α4β2 nicotinic Acetylcholine receptor agonist. In addition to clinical use as a smoking cessation aid, It has demonstrated anti-depressant effects in mice.
