Hypoglycin A inhibits

Hypoglycin A is transaminated to methylenecyclopropyl-alanine (MCPA) and subsequently undergoes oxidative decarboxylation to form MCPA-CoA, which accumulates in the matrix of liver mitochondria of fasted rats (Melde et al., 1989, 1991) and inhibits the β-oxidation of long-chain fatty acids at the butyryl-CoA dehydrogenase stage (Tanaka, 1972; Tanaka and Ikeda, 1990; von Holt et al., 1964, 1966). Oxidation of the carbon chains of valine and isoleucine is also impaired Clofibrate feeding apparently protected the animals against the toxic, hypoglycemic and hypothermic effects of hypoglycin...and completely prevented the ultrastructural damage caused by hypoglycin. After hypoglycin administration, hepatic mitochondrial butyryl-CoA dehydrogenase activity was inhibited by more than 90% and, surprisingly, the activity of the peroxisomal enzymes studied was largely preserved Hypoglycin A (HGA) toxicity, following ingestion of material from certain plants, is linked to an acquired multiple acyl-CoA dehydrogenase deficiency known as atypical myopathy, a commonly fatal.

Hypoglycin A is one of the toxic compounds found in unripe ackees and is capable of inducing hypoglycemia. A fall in blood glucose occurred after administration of hypoglycin A. The lowest level of 42.60 +/- 4.84 mg/dl was attained 3 hr after administration of the drug Recently, Tanaka et al. (18) have shown that hypoglycin A inhibits dehydrogenation of isovnleryl-CoA and oc-methylbutyryl- CoA by liver slices in vitro, and that it induces isovaleric and * This research was supported in part by Grants AWl.ii98 and AX01392 from the National Institutes of Health - Contains toxic aminoacid hypoglycin A. - Most of the active substance is found in the seeds (autumn) and seedlings (spring). - Hypoglycin A inhibits beta oxidation of fatty acids in muscles and leads to so called Atypical myopathy (rhabdomyolysis). - Signs include apathy, colic pains in belly, sweating, reluctance to move, dark urine

Hypoglycin and MCPA are both toxic. MCPA inhibits several enzymes involved in the breakdown of acyl CoA compounds. Hypoglycin binds irreversibly to coenzyme A, carnitine and carnitine acyltransferases I and II reducing their bioavailability and consequently inhibiting beta oxidation of fatty acids Hypoglycemia is an important problem in infants and children. It can cause seizures, coma, permanent brain damage, and death. Several metabolic systems are activated during fasting to prevent hypoglycemia. Thus, hypoglycemia can be viewed as a failure of one these fasting systems or an abnormality in one of the hormones that controls these systems
