Ritalinic acid is an inactive, major metabolite of methylphenidate, a schedule II drug in the United States commonly used as a psychostimulant drugs methylphenidate and ethylphenidate. The elimination half-life of methylphenidate is relatively short (approximately 2 hours); therefore it is also available in extended release (ER) forms. The main metabolite is ritalinic acid, and the methylphenidate metabolites are mostly excreted in urine.

Traumatic acid (TA) is a plant hormone (cytokinin) that in terms of chemical structure belongs to the group of fatty acids derivatives. It was isolated from Phaseolus vulgaris. It was discovered, that TA showed a stimulatory effect on antioxidative enzyme activity, reduced glutathione, thiol group content, and lipid peroxidation in physiological conditions. TA exhibited protective properties against ROS production. Thus, TA could be a potentially powerful agent with applications in the treatment of many skin diseases connected with oxidative stress and collagen biosynthesis disorders.

EC23, also known as AGN 190205, is photostable synthetic analog of All-trans retinoic acid (ATRA). EC23 is an agonist of retinoic acid receptors: alpha, beta and gamma, while having no appreciable activity for retinoid X receptors and weakly activates aryl hydrocarbon receptor. It was shown, that EC23 induced neural differentiation in human pluripotent embryonic stem cells.

p-Toluenesulfonic acid (PTSA) is an organic compound with the formula CH3C6H4SO3H. An aromatic sulfonic acid, often used as a strong acid catalyst. p-Toluenesulfonic acid monohydrate has been used as a reducing agent for the reductive amination of ketones and aldehydes. In the presence of p-Toluenesulfonic acid monohydrate novel deazaflavin-cholestane hybrid compounds have been synthesized in a condensation reaction. 2-Phenylethyl alpha-glucoside has also been synthesized in the presence of p-Toluenesulfonic acid monohydrate. p-toluenesulfonic acid esters, are a common class of reagents used in the pharmaceutical industry as alkylating agents, catalysts, and in purification steps of the chemical synthesis of a drug substance.

5-Methyl-3-phenyl-4-isoxazolylcarbonyl chloride is an intermediate for the synthesis of synthetic penicillins. 5-Methyl-3-phenyl-4-isoxazolylcarbonyl chloride can be prepared by the reaction of 5-methyl-3-phenyl-4-isoxazolecarboxylic acid (II) with thionyl chloride in the presence of DMF.

Catharanthine is a terpene indole alkaloid produced by the medicinal plant Catharanthus roseus. Catharanthine is derived from strictosidine, but the exact mechanism by which this happens is currently unknown. Catharanthine is one of the two precursors that form vinblastine, the other being vindoline.

Iminodibenzyl is an impurity in commercial preparations of Carbamazepine. It is the final product of antidepressant imipramine oxidation. Iminodibenzyl is a building block of many antipsychotic drugs. Iminodibenzyl derivatives demonstrated anti-leishmanial activity. Iminodibenzyl, in combination with 3-methyl-2-benzothiazolinonehydrazone hydrochloride are used as chromogenic co-substrates for quantification of hydrogen peroxide and glucose.

Coniine is a neurotoxic piperidine alkaloid found in poison hemlock (Conium maculatum L.). Coniine which is considered to be racemic mixture first described by Gieseke in 1827; von Hoffman confirmed the structure in 1881; Ladenburg perfermed synthesis in 1886. Coniine enantiomers are nicotinic acetylcholine receptor (nAChR) agonists. The relative potencies of these enantiomers on TE-671 cells expressing human fetal nicotinic neuromuscular receptors had the rank order of (-)-coniine > (+/-)-coniine > (+)-coniine. The rank order potency in SH-SY5Y cells which predominately express autonomic nAChRs was: (-)-coniine>(+)-coniine> (+/-)-coniine.
