Helminthosporium velutinum yone96 produces cyclohelminthol X (1), a unique hexa-substituted
spirocyclopropane. Although its molecular formula and NMR spectral data resemble …

The effectiveness and limitations of density functional theory (DFT) calculations in the
structural determination of complexed and conformationally flexible natural products were …

Cyclohelminthols Y1–Y4 (1–4) were isolated from the culture broth of Helminthosporium
velutinum yone96. These compounds are diastereomers to each other featuring 3-azabicyclo[…

Oxygenated cyclopentene systems are unique structural motifs found in fungal polyketides
such as terrein, cyclohelminthols, and palmaenones. Here we report the identification of the …

S–1358 (S-n-butyl-S′-p-tert-butylbenzyl n-3-pyridylimidodithiocarbonate) remarkably
inhibited growth of Monilinia fructigena at 10 μm, causing excessive branching and distortion of …

When Moniiinia fructigena was treated with S–1358 at a concentration of 10 μm, both
quality and quantity of digitonin-precipitable sterols were markedly altered. The amount of …

Fungitoxic properties of a new compound, Sn-butyl S• Œ-p-tert-butylbenzyl N-3-pyridylimidodithiocarbonate(S-1358),
were examined. Some genera in Ascomycetes and Fungi …

Although there is a similarity in the orbital interaction scheme between quinhydrone and N,N,N′,N′‐tetramethyl‐p‐diaminobenzene‐chloranil
complex, the stacking conformations …

Since S-n-butyl S'-p-tert-butylbenzyl N-3-pyridyldithiocarbonimidate, a potent fungicide to
powdery mildew, is known to inhibit ergosterol biosynthesis in Monilinia fructigena, the …

Fungicidal activities of S-alkyl S′-p-substituted benzyl N-3-pyridyldithiocarbonimidates
toward Coniothyrium diplodiella, Scleotinia sclerotiorum (on agar medium) and Sphaerotheca …
