Ecdysone is a major steroid hormone in insects and herbs. Ecdysone triggers mineralocorticoid receptor activation and induces cellular apoptosis. Ecdysone signaling through Ecdysone receptor isoform B1 is required cell autonomously for the muscle death.

Increased levels of erucic acid (22:1n9) have been found in the red blood cell membranes of autistic subjects with developmental regression (PMID: 16581239 ). Erucic acid (13(Z)-Docosenoic Acid) is broken down long-chain acyl-coenzyme A (CoA) dehydrogenase, which is produced in the liver. This enzyme breaks this long chain fatty acid into shorter-chain fatty acids. human infants have relatively low amounts of this enzyme and because of this, babies should not be given foods high in erucic acid. Erucic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism.

Bisphenol A is an endogenous metabolic compound of phenols and is widely used in the production of epoxy resins and polycarbonate plastics. It is reproductive, developmental and systemic toxicant and is often classified as an endocrine disruptor. It has been linked to many diseases, including respiratory disease, cardiovascular disease, diabetes, kidney disease, obesity and reproductive disorders.

Pyrrole-2-carboxylic acid (Minaline) was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A'-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) ' was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

2-Bromobiphenyl is a persistent organic pollutant (POP) found primarily in soil and water. It is a known human carcinogen and has been linked to a variety of health effects including reproductive and developmental toxicity.

Dimethyl phthalate (Fermine) has many uses, including in solid rocket propellants, plastics, and insect repellants. Acute (short-term) exposure to dimethyl phthalate, via inhalation in humans and animals, results in irritation of the eyes, nose, and throat. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic effects of dimethyl phthalate in humans. Animal studies have reported slight effects on growth and on the kidney from chronic oral exposure to the chemical. EPA has classified dimethyl phthalate as a Group D, not classifiable as to human carcinogenicity.

Abscisic Acid (Dormin) is a plant hormone, which is involved in many plant developmental processes, modulates ion homeostasis and metabolism, and inhibits germination and seedling growth.
