Meprobamate

2-[(carbamoyloxy)methyl]-2-methylpentyl carbamate

C9H18N2O4 (218.1267)


A carbamate with hypnotic, sedative, and some muscle relaxant properties, although in therapeutic doses reduction of anxiety rather than a direct effect may be responsible for muscle relaxation. Meprobamate has been reported to have anticonvulsant actions against petit mal seizures, but not against grand mal seizures (which may be exacerbated). It is used in the treatment of anxiety disorders, and also for the short-term management of insomnia but has largely been superseded by the benzodiazepines. (From Martindale, The Extra Pharmacopoeia, 30th ed, p603) Meprobamate is a controlled substance in the U.S. D002491 - Central Nervous System Agents > D002492 - Central Nervous System Depressants > D006993 - Hypnotics and Sedatives D002492 - Central Nervous System Depressants > D014149 - Tranquilizing Agents > D014151 - Anti-Anxiety Agents D002491 - Central Nervous System Agents > D011619 - Psychotropic Drugs > D014149 - Tranquilizing Agents N - Nervous system > N05 - Psycholeptics > N05B - Anxiolytics > N05BC - Carbamates D018373 - Peripheral Nervous System Agents > D009465 - Neuromuscular Agents C78272 - Agent Affecting Nervous System > C29756 - Sedative and Hypnotic C78272 - Agent Affecting Nervous System > C264 - Anticonvulsant Agent D002491 - Central Nervous System Agents > D000927 - Anticonvulsants

   

Isoleucyl-Serine

2-[(2-Amino-1-hydroxy-3-methylpentylidene)amino]-3-hydroxypropanoate

C9H18N2O4 (218.1267)


Isoleucyl-Serine is a dipeptide composed of isoleucine and serine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
