A family of aminoacyl alkyl citrate compounds called viridiofungins, a
re novel squalene synthase inhibitors. The compounds have broad spectr
um fungicidal activity but lack antibacterial activity. Although the c
ompounds inhibit squalene synthase, the first committed step in ergost
erol biosynthesis, results presented in this paper show that inhibitio
n of fungal growth is not related to inhibition of ergosterol synthesi
s.
