New penicillide derivatives isolated from Penicillium simplicissimum
Two new penicillide derivatives, secopenicillides A and B, were isolated from the extract of Penicillium simplicissimum IFM 53375, the antifungal substances of this fungus, by spectroscopic investigation and chemical correlation.
A new pentanorlanostane derivative, cladosporide A, as a characteristic antifungal agent against Aspergillus fumigatus, isolated from Cladosporium sp.
The 4beta-aldehyde residue in 1 might be essential for the antifungal activity, since 23,24,25,26,27-pentanorlanost-8-ene-3beta,22-diol showed no inhibition against the above four fungi.

The dichloromethane extract of Talaromyces convolutus cultivated on barley exhibited antifungal activity against Candida albicans and four new tetramic acid derivatives, talaroconvolutins A, B, C, and D, were isolated along with ZG-1494alpha (5), and mitorubrin derivatives.
New citrinin derivatives isolated from Penicillium citrinum
Three new coupling compounds derived from citrinin (9) and 2,3,4-trimethyl-5,7-dihydroxy-2,3-dihydrobenzofuran (8) – penicitrinone A (1), penicitrinol A (2) and penicitrinone B (3) – and a new…

Two new dioxopiperazine derivatives, arestrictins A and B, were isolated from the organic extract of the xerophilic fungi, Aspergillus restrictus and As pergillus penicilloides, and the known peptide, asperglucide, was determined.
Novoamauromine and ent-Cycloechinulin: two new diketopiperazine derivatives from Aspergillus novofumigatus.
Two new diketopiperazine metabolites, novoamauromine and ent-cycloechinulin, have been isolated from Aspergillus novofumigatus CBS117520 on the basis of spectroscopic and chemical investigation.
New Vermistatin Derivatives Isolated from Penicillium simplicissimum
Four new vermistatin derivatives, dihydrovermistatin (1), acetoxydihydrovermistatin (2), hydroxydihydrovermistatin (3), and penisimplicissin (4) were isolated along with vermistatin (5), penicillide,…
