General description

Chemical structure: macrolide
Concanamycin A belongs to the plecomacrolide family and comprises an 18-membered tetraenic macrolide ring.


Concanamycin A has been used:
  • as a lysosomal inhibitor in young and old fibroblasts
  • as a vacuolar-type H+-ATPase inhibitor in presynaptic vesicles
  • as a lysosomal acidification blocker in HepG2 hepatocytes cells

Biochem/physiol Actions

Concanamycin A (ConA) inhibits acidification of organelles and perforin-mediated cytotoxicity. It is a vacuolar-type v-ATPase inhibitor. ConA possesses antiprotozoal and antineoplastic properties. It mediates inhibition of the negative factor (Nef) protein of the human immunodeficiency virus.
