Nonribosomal cyclopeptide cyclosporin A (CsA), produced by fungus <i>Tolypocladium inflatum</i>, is an extremely important immunosuppressive drug used in organ transplantations and for therapy of autoimmune diseases. Here we report for the first time production of CsA, along with related cyclosporins B and C, by <i>Tolypocladium inflatum </i>strains of marine origin (White Sea). Cyclosporins A–C contain an unusual amino acid, (4<i>R</i>)-4-((<i>E</i>)-2-butenyl)-4,<i>N</i>-dimethyl-l-threonine (MeBmt), and are prone to isomerization to non-active isocyclosporine by N→O acyl shift of valine connected to MeBmt in acidic conditions. CsA and isoCsA are not distinguishable in MS analysis of [M+H]<sup>+</sup> ions due to the rapid [CsA+H]<sup>+</sup>→[isoCsA+H]<sup>+</sup> conversion. We found that the N→O acyl shift is completely suppressed in cyclosporine [M+2H]<sup>2+</sup> ions, and their MS/MS fragmentation can be used for rapid and unambiguous analysis of cyclosporins and isocylosporins. The fragmentation patterns of [CyA+2H]<sup>2+</sup> and [isoCyA+2H]<sup>2+</sup> ions were analyzed and explained. The developed approach could be useful for MS analysis of other peptides containing β-hydroxy-α-amino acids.

ABSTRACT Here, we report a new draft genome sequence of an isolate of the ascomycete Claviceps paspali that is responsible for ergot disease in grasses of the Paspalum genus. This new draft genome sequence will provide useful data for evaluating intraspecies and interspecies genome variation in C. paspali and other Claviceps genus members.

Foi realizado um levantamento nos arquivos do Laboratório de Patologia Veterinária (LPV) da Universidade Federal de Santa Maria (UFSM) e revisados os laudos de necropsias de bovinos realizadas entre 1990 e 2005. Foram revisados 2.912 casos referentes a necropsias realizadas por membros do LPV ou a materiais de necropsias realizadas por veterinários de campo que enviaram amostras para avaliação histológica no LPV. Em 461 (15,83%) das necropsias, a causa da morte foi atribuída à ingestão de plantas tóxicas. Em ordem decrescente de freqüência, intoxicações pelas seguintes plantas foram diagnosticadas: Senecio spp (56,14%), Pteridium aquilinum (12,06%), Ateleia glazioviana (10,31%), Solanum fastigiatum (5,04%), Baccharis coridifolia (3,29%), Xanthium cavanillesii (3,07%), Senna occidentalis (2,63%), Ramaria flavo-brunnescens (2,41%), Amaranthus spp (2,19%), Vicia villosa (1,54%), Ipomoea batatas, Prunus sellowii e polpa cítrica (0,44% cada), Cestrum parqui, Claviceps paspali, Claviceps purpurea, Brachiaria spp e Lantana sp (0.22% cada). Em um determinado surto o número de bovinos afetados era substancialmente maior que o número de necropsias realizadas. São discutidos os aspectos relacionados à distribuição geográfica, fatores que induziram a ingestão, índices de morbidade, mortalidade e letalidade, sinais clínicos, achados de necropsia e histopatológicos para cada intoxicação. Quando conhecidos, foram incluídos na discussão aspectos relacionados ao princípio ativo e a patogenia da intoxicação.
