It can be produced by the palladium-catalyzed hydrocarboxylation of cyclopentene: [2] C 5 H 8 + CO + H 2 O → C 5 H 9 CO 2 H. An alternative route involves the Favorskii rearrangement, which is a base-induced ring contraction of 2-chlorocyclohexanone to give the ester methyl cyclopentanecarboxylate, which can be hydrolyzed to the carboxylic ...
Metopimazine is an approved prescription drug in France under the brand name Vogalene® [8] that has been used for the treatment of nausea and vomiting. [9] Vogalene® is available under different forms, including 15 mg capsules, 7.5 mg orally disintegrating tablets, 5 mg suppository, 0.1% oral liquid, and a 10 mg/mL intravenous (IV) solution approved for the prevention of chemotherapy-induced ...
As with other members of the penicillin family, the chemical structure of oxacillin features a 6-aminopenicillanic acid nucleus with a substituent attached to the amino group. The 6-aminopenicillanic acid nucleus consists of a thiazolidine ring attached to a β-lactam ring, which is the active moiety responsible for the antibacterial activity ...
Meprobamate—marketed as Miltown by Wallace Laboratories and Equanil by Wyeth, among others—is a carbamate derivative used as an anxiolytic drug. It was the best-selling minor tranquilizer for a time, but has largely been replaced by the benzodiazepines due to their wider therapeutic index (lower risk of toxicity at therapeutically prescribed doses) and lower incidence of serious side effects.
Oxiracetam is well absorbed from the gastrointestinal tract with a bioavailability of 56-82%. [6] Peak serum levels are reached within one to three hours after a single 800 mg or 2000 mg oral dose, with the maximal serum concentration reaching between 19 and 31 μg/ml at these doses.
Tofacitinib, sold under the brand Xeljanz among others, is a medication used to treat rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, polyarticular course juvenile idiopathic arthritis, and ulcerative colitis.
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
Methcathinone / ˌ m ɛ θ ˈ k æ θ ɪ ˌ n oʊ n / (α-methyl amino-propiophenone or ephedrone) (sometimes called "cat" or "jeff" or "catnip" or "M-Kat" or "kat" or "intash") is a monoamine alkaloid and psychoactive stimulant, a substituted cathinone.
