Louis Pasteur - pioneering stereochemist. Chirality can be traced back to 1812, when physicist Jean-Baptiste Biot found out about a phenomenon called "optical activity." [10] Louis Pasteur, a famous student of Biot's, made a series of observations that led him to suggest that the optical activity of some substances is caused by their molecular asymmetry, which makes nonsuperimposable mirror ...
Chiral molecules in the receptors in our noses can tell the difference between these things. Chirality affects biochemical reactions, and the way a drug works depends on what kind of enantiomer it is. Many drugs are chiral and it is important that the shape of the drug matches the shape of the cell receptor it is meant to affect.
Chiral analysis refers to the quantification of component enantiomers of racemic drug substances or pharmaceutical compounds. Other synonyms commonly used include enantiomer analysis, enantiomeric analysis, and enantioselective analysis.
East African drug trade refers to the sale and trafficking of illegal drugs that take place in East African countries like Kenya, Tanzania, Uganda, Somalia, and Ethiopia. . The most prevalent types of drugs traded in East Africa are heroin, marijuana, cocaine, methamphetamine, and khat, all of which are strictly prohibited in East African countri
Many young people in West and Central Africa have become addicted to drugs with between 5.2% and 13.5% using cannabis, the most widely used illicit substance on the continent, according to the ...
A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. [16] [17] The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. [18]
Fenoprofen is chiral drug with one stereogenic center and exists as chiral twins. (S)-enantiomer has the desired pharmacological action where as the (R)-isomer is less active. It is observed that there is stereoselective bioconversion of the (R)- to (S)-fenoprofen. This stereoselective conversion is called chiral inversion. [5] [6]
Penicillamine is a chiral drug with one stereogenic center; the two enantiomers have distinctly different physiological effects. (S)-penicillamine (D-penicillamine, having (–) optical rotation) is antiarthritic. [18]
