Blocks Arabanogalactan synthesis via arabinosyl transferase in mycobacteria
Ethambutol
Inhibits fungal enzyme, squalene epoxidase, blocking lanosterol synthesis
Terbinafine
Inhibit fungal cell wall synthesis by inhibiting synthesis of Beta Glucan
Echinocandins (–fungins)
Binds fungal ergosterol forming pores that disrupt cell membrane integrity allowing the leakage of electrolytes
