摘要: To find new fungicidal lead compounds, based on the catalytic mechanism of chitin synthase, a series of novel nucleoside compounds containing thiourea were designed via the method of linking active sub-structures, in which the thiourea with high fungicidal activity was combined to the uridine part of polyoxins and nikkomycins. The target compounds were synthesized from uridine in 5 steps. Their structures were confirmed by IR, H-1 NMR spectra and elemental analysis. The preliminary bioassay results indicated that some compounds showed obvious inhibition effects against Phomopsisasparagi bubak, especially, and the fungicidal activity of 6m (97.2%) at 50 mu g/mL is similar to that (100%) of polyoxin B.
