Antimicotici

D75-4590, a β-1,6-Glucan synthetase inhibitor, combats fungal infections by targeting cell walls.

Amphotericin A is a polyene macrolide antibiotic, which is derived primarily from the soil bacterium *Streptomyces nodosus*. This compound functions by binding to ergosterol, an essential component of fungal cell membranes. This binding creates pores in the membrane, increasing its permeability and ultimately leading to cell death. Unlike its more widely used counterpart Amphotericin B, Amphotericin A is less frequently utilized but is critical in the study and understanding of antifungal activity.

1-(6-Amino-3,5-difluoro-2-pyridinyl)-7-[3-[3-[[1-(6-amino-3,5-difluoro-2-pyridinyl)-3-carboxy-8-chloro-6-fluoro-1,4-dihydro-4-oxo-7-quinolinyl]amino]-2-hydroxypropoxy]-1-azetidinyl]-8-chloro-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid is a fluoroquinolone antibiotic, engineered through synthetic chemistry. It is derived from chemical sources involving complex organic synthesis, highlighting its intricate molecular architecture. Its mode of action is distinctive, as it inhibits bacterial DNA gyrase and topoisomerase IV, enzymes crucial for DNA replication and transcription. This interference with bacterial DNA processes results in bactericidal effects, effectively eliminating susceptible bacterial strains.
