Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...
Some chemicals found in trace amounts in food, as well as some dietary supplements, have been shown to inhibit 5-LOX; these include baicalein, caffeic acid, curcumin, [3] hyperforin and St John's wort. [8] [9] [10]
A deuterated drug is a small molecule medicinal product in which one or more of the hydrogen atoms in the drug molecule have been replaced by its heavier stable isotope deuterium. Because of the kinetic isotope effect , deuterium-containing drugs may have significantly lower rates of metabolism , and hence a longer half-life .
The majority of pre-packaged foods are required to list all ingredients, including all food additives such as color; however section B.01.010 (3)(b) of the Regulations provide food manufacturers with the choice of declaring added color(s) by either their common name or simply as "colour". [24] The maximum permitted level of tartazine is 300 ppm ...
"drugs that are chemically related to the prototype, or other chemical compounds which have an identical mechanism of action" "drugs which have more or less identical clinical outcomes to pre‐existing drugs" "a drug with a similar chemical structure or the same mechanism of action as a drug that is already marketed". [1]
For example, the replacement of a hydrogen atom with a fluorine atom at a site of metabolic oxidation in a drug candidate may prevent such metabolism from taking place. Because the fluorine atom is similar in size to the hydrogen atom the overall topology of the molecule is not significantly affected, leaving the desired biological activity ...

In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...
