Buy 6-APA Drug Online
6-APA is the core of penicillins. It is obtained from the fermentation brew of the Penicillium mold and used as the main starting block for the preparation of numerous semisynthetic penicillins.
In 1958, Beecham scientists in the UK discovered the penicillin nucleus, 6-APA. From that starting material, a large number of new semisynthetic penicillins could be designed, whose activity was directed against problem infections.
6-aminopenicillanic acid is a penicillanic acid compound having a (6R)-amino substituent. The active nucleus common to all penicillins, it may be substituted at the 6-amino position to form the semisynthetic penicillins, resulting in a variety of antibacterial and pharmacologic characteristics. It derives from a penicillanic acid. It is a conjugate base of a 6-aminopenicillanate. It is a tautomer of a 6-aminopenicillanic acid zwitterion.

6-APA derivatives were considered as selective labels for the construction of bifunctional linkers dedicated to the oriented immobilization of proteins on materials. Sulbactam-like compounds (i.e., 6-β-sulfonamido-penam sulfones) and penicillin G—like compounds (i.e., para-substituted 6-β-phenylacetamido-penams) were prepared and tested as irreversible inhibitors of representative β-lactamases and D,D-peptidases, respectively. The activity of the modified antibiotics was preserved despite their substitution with various anchoring arms. The (2-nitro-4,5-dimethoxy)-benzyl esters revealed of particular interest due to their capacity to acylate BlaR-CTD without deprotection.
