Pregnenolone carbonitrile (PCN) is a synthetic steroid with a nitrile group at the 17 position. It is a potent inhibitor of steroidogenesis, specifically acting as a competitive inhibitor of the enzyme 3β-hydroxysteroid dehydrogenase. This inhibition disrupts the production of various steroid hormones, including cortisol, aldosterone, and testosterone. PCN has been studied for its potential therapeutic applications in various conditions, such as Cushing's syndrome, polycystic ovary syndrome, and prostate cancer. It has also been investigated for its effects on brain function and neuroprotection. However, its use in clinical practice is limited due to its potential side effects, including adrenal insufficiency and hepatotoxicity.'
Pregnenolone Carbonitrile: A catatoxic steroid and microsomal enzyme inducer having significant effects on the induction of cytochrome P450. It has also demonstrated the potential for protective capability against acetaminophen-induced liver damage. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

| Poliomyelitis An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5) | 0 | 2.06 | 1 | 0 |
