K. Nesmerak et al., ANTIFUNGAL EFFECTS OF NEW HETEROCYCLIC-COMPOUNDS, 6H-PYRIMIDO[2,1-A]ISOINDOLE DERIVATIVES, Folia microbiologica, 43(1), 1998, pp. 39-41
Minimal inhibitory concentrations for 10 new condensed isoindole deriv
atives were established by the agar diffusion method. Benzo[b]-6H-pyri
mido[2,1a]isoindole-4-one exhibited a broad antifungal effect; the obs
erved MIC (mg/L) were 7 (K. lactis), 8 (C. pseudotropicalis), 17 (W. f
luorescens), 22 (E. magnusii), 31 (P. membranaefaciens), 32 (S. alluvi
us) and 32 (S. cerevisiae). The compound also inhibited the growth of
B. subtilis (MIC 9 mg/L). No effect on the growth of E. coli was found
.
