Chemistry Nobel Recognizes Breakthroughs in Molecular Handedness

Chemistry Nobel: Explaining Molecular Orientation, Elegantly · freepressjournal.in

Some molecules come in two forms that are like left and right hands: they look similar but are mirror images.

Living things often use only one of those forms for certain important molecules.

Henri Kagan found a way for a catalyst to help make more of one form than the other.

Kenso Soai later showed that a molecule could help make more copies of its own form.

This kind of control can help researchers make medicines more carefully.

The two forms can behave differently in the body, so choosing the right one matters.

The article says Kagan's work helped with the synthesis of the anti-HIV drug Efavirenz.

Molecular handedness also affects scents, and the article says it is part of the larger mystery of how life developed.

Key facts

Researchers named
Henri Kagan and Kenso Soai
Kagan's cited advance
In 1986, he showed that manipulating a chiral catalyst could produce an excess of one mirror-image form.
Soai's contribution
He demonstrated autocatalysis, where a molecule acts as a catalyst for producing more of itself.
Drug example
The article credits Kagan's amplification of a molecular mirror form with effective synthesis of the anti-HIV drug Efavirenz.
Other medicine mentioned
Levodopa is cited as containing one effective chiral form.
Life's molecular orientation
The article says amino acids are L-configured, while sugars in DNA and RNA are D-configured.
Safety context
The article discusses the Thalidomide crisis as an example of the importance of testing drug molecules and their orientation.
