The aggregation behavior of 6-isocassine and N-methyl-6-isocassine, two piperidin-3-ol alkaloids isolated respectively from the barks of Prosopis nigra and
P. affinis, was investigated using a combination of NOE experiments and diffusion measurements in solvents of varying polarity and hydrogen bonding
capacity. While the NOE enhancements for N-methyl-6-isocassine are positive, regardless of the solvent, those for 6-isocassine shift from negative to positive
when going from chloroform-d to methanol-d4 solution. In addition, despite the self-diffusion coefficients of both compounds being virtually identical in
methanol-d4, N-methyl-6-isocassine diffuses nearly twice as fast as the non-methylated alkaloid in chloroform-d. The changes in rotational and translational
dynamics observed between solvents for 6-isocassine suggest that the molecule forms dimeric head-to-head aggregates in non-polar aprotic environments, a
behavior that could help explain the biological mode of action that has been proposed for this type of alkaloids. |

ABSTRACT: This study aimed to do a brief review of enzootic calcinosis in sheep and to report two outbreaks of Nierembergia rivularis poisoning in sheep in Uruguay. The outbreaks occurred in farms located on an island (Outbreak A) and on the border (Outbreak B) of the Rincón del
Bonete lake. Sheep of all ages were affected, with the exception of suckling lambs. The first clinical signs occurred in early October, and deaths occurred from December to February. Outbreaks A and B had morbidity of 10%, and the mortality was 7.2% and 2.8% in Outbreaks
A and B, respectively. The clinical signs included weight loss, retracted abdomen, stiff gait, and kyphosis. An autopsy was performed on one sheep from each outbreak. Pulmonary and arterial calcification, nephrocalcinosis, and osteopetrosis were observed in gross and microscopic examination in both sheep. Thyroid C-cell hyperplasia and carcinoma was observed in sheep A. Sheep B showed thyroid C-cell hyperplasia and parathyroid chief cell atrophy. The parathyroid was not examined in the sheep from Outbreak A. The differential diagnosis of enzootic calcinosis in southern South America should consider four toxic plants in the Solanaceae family: Solanum glaucophyllum, Solanum stuckertii, Nierembergia veitchii, and Nierembergia rivularis.
RESUMO: Este trabalho faz uma breve revisão da calcinose enzoótica em ovinos e descreve dois surtos de intoxicação por Nierembergia rivularis em ovinos no Uruguai. Os surtos ocorreram em propriedades localizadas em uma ilha (Surto A), e nas margens (Surto B) do lago do Rincón del Bonete. Foram afetados ovinos de todas as idades, exceto cordeiros lactentes. Os primeiros sinais clínicos ocorreram no início de outubro e as mortes de dezembro a fevereiro. Morbidade de 10% foi observada nos Surtos A e B. A mortalidade foi de 7,2% e 2,8% nos Surtos A e B, respectivamente. Os sinais clínicos incluíram perda de peso, abdômen retraído, marcha rígida e cifose. Foram necropsiados um animal de cada rebanho. Observou-se mineralização arterial e pulmonar, nefrocalcinose e osteopetrose no exame macroscópico e histológico dos dois ovinos. Hiperplasia e carcinoma de células C da tireoide foram observados no ovino A. O ovino B apresentou hiperplasia de células C da tireoide e atrofia das células principais da paratireoide. As paratireoides do ovino A não foram examinadas. O diagnóstico diferencial da calcinose enzoótica no Sul da América do Sul deve considerar quatro plantas calcinogênicas da família Solanaceae: Solanum glaucophyllum, Solanum stuckertii, Nierembergia veitchii e Nierembergia rivularis.
