Biotransformation of Neuropeptides
Neuroendocrinology, 1984The ability of neuropeptides to act as precursors for smaller, biologically active fragments is discussed in terms of their biotransformation. This process may involve cleavage of the parent peptide by peptidase enzymes to produce shorter polypeptides with defined biological activity, though other enzymic processes such as sulphation and acetylation ...

Biotransformation of Phencyclidine
Drug Metabolism Reviews, 1985PCP is metabolized extensively in the body via a variety of metabolic routes. Biotransformation is a major mechanism of PCP elimination in humans and termination of PCP action in mice. In general, PCP metabolites are less active pharmacologically than PCP itself.

During the past several years it has become generally accepted that the incidence of adverse reactions to drugs in patients increase with age (1–3). However, the reasons for the increased incidence are frequently obscure and often differ with the drug.

Serum digoxin and metabolites were assayed in plasma and urine by HPLC in 10 dialysis-dependent patients with end-stage renal failure (group I) and in five patients with comparatively normal renal function (group II) after ingestion of 150 muCi 3H-digoxin-12 alpha.

Biotransformations using enzymes and whole microbial cells have been used for centuries to produce foods and beverages. However, only in the last century we have developed methods to understand and improve biocatalyst stability and productivities. Engineering and directed evolution of enzymes have enhanced enzymatic activity and increased the number of

Biotransformation of Plant‐Derived Phenolic Acids
Biotechnology Journal, 2018Phenolic acids are abundant biomass feedstock that can be derived from the processing of lignin or other byproducts from agro‐industrial waste. Although phenolic acids such as p‐hydroxybenzoic acid, p‐coumaric acid, caffeic acid, vanillic acid, cinnamic ...

Biotransformation of Sevoflurane
Anesthesia & Analgesia, 1995Several characteristics of sevoflurane biotransformation are apparent from the preceding investigations. Metabolism is rapid, with fluoride and HFIP appearing in plasma within minutes after the start of sevoflurane administration (38-40,51). Peak plasma fluoride concentrations generally occur within approximately 1 h after the termination of ...

Two healthy subjects took 3H-digoxigenin-12 alpha and unlabeled digoxigenin. Metabolites were assayed by high-pressure liquid chromatography (HPLC) in serum and urine. Of the tritium activity in the serum at 30 min, less than 26% chromatographed with digoxigenin; the rest chromatographed as metabolites, most of which were polar.
