α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach using carbamoylmethyl esters as acyl donors in organic media

The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach is demonstrated in several model systems carried out in organic media with low water content. Furthermore, this approach is successfully applied to the construction of the Leu-enkephalin sequence via a 4 + 1 segment coupling.

Methionine5 -enkephalin sulfoxides and sulfones

Methionine 5 -enkephalin sulfoxides and sulfones having agonist activity at opiate receptors are disclosed herein. These sulfoxides and sulfones are useful as analgesics, non-addicting narcotic antagonists and anti-diarrheal agents.
