Chirality thalidomide

Webtwo versions of a chiral molecule are called "enantiomers". One is called "right-handed", and the other "left-handed". A shocking example of chirality Introduced in 1957 in West Germany, the drug Thalidomide was promoted for relief of morning sickness in pregnant women. A chiral compound, one enantiomer has the desired effect, while WebThalidomide is a classical example highlighting the alleged role of chirality in drug toxicity. Thalidomide was a racemic therapeutic and prescribed to pregnant women to control nausea and vomiting. The drug was withdrawn from world market when it became evident that the use in pregnancy causes phocomelia (clinical conditions where babies are ...

3.5: Naming chiral centers- the R and S system

WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound 1 has a chiral carbon center, because it is attached to four different ... The precise mechanism of action for thalidomide is not known, although efforts to identify thalidomide's teratogenic action generated 2,000 research papers and the proposal of 15 or 16 plausible mechanisms by 2000. As of 2015 , the main theories were inhibition of the process of angiogenesis, its inhibition of cereblon, a ubiquitin ligase, and its ability to generate reactive oxygen species which in turn kills cells. In 2024, results were first published which suggested that thalid…
