amino amide vs amine ester
Are local anesthetics amine or aromatic?
Most local anesthetics contain an aromatic group and an amine group separated by an intermediate chain (Table 1). The clinically useful local anesthetics fall into one of two chemical groups. Amino-esters (procaine, chloroprocaine and tetracaine) contain an ester link between the aromatic portion and the intermediate chain.
How are esters converted into amides?
Please let us know in the Reviews section here. Esters can be converted into amides by reacting with amines in an aminolysis reaction. The reaction goes by a nucleophilic addition-elimination mechanism.
Why are amino esters called amide local anaesthetics?
They are named for their ester bond and are unlike amide local anaesthetics. Structurally, amino esters consist of three molecular components: The chemical linkage between the lipophilic part and the intermediate chain can be of the amide -type or the ester-type, and is the general basis for the current classification of local anesthetics.
