Limonoids from Toona ciliata and speculations on their chemosystematic and ecol...
Pinheiro, Antônio L.; Vieira, Paulo C.; Agostinho, Sueli M.; Das, M. Fátima; Silva, G. F. da; Vilela, Evaldo F.; Fernandes, Joāo B.Evolution of limonoids in the Meliaceae appears to be consistent with the resistance of Melioideae against the shoot borer Hypsipyla. The limonoid chemistry of Toona, which has shown absence of attacks of H. grandella, is reminiscent of Melioidease. An investigation of T. ciliata, has led to the identification of two novel meliacin butenolides, 21-hydroxycedrelonelide and 23-hydroxycedrelonelide, two known limo...

Pinheiro, Antônio L.; Braga, Patrícia A. de Campos; Soares, Márcio Santos; Silva, M. Fátima das G. F. da; Vieira, Paulo C.; Fernandes, João B.The stem of Cabralea canjerana (Vell.) Mart. yielded three new dammarane triterpenes 20S,24S-epoxy-7β,25-dihydroxy-3,4-secodammar-4(28)-en-3-oic acid, 20S,24S-epoxy-7β,15α,25-trihydroxy-3,4-secodammar-4(28)-en-3-oic acid and 20S,24R-epoxy-7β,22ξ,25-trihydroxy-3,4-secodammar-4(28)-en-3-oic acid, which were identified on the basis of spectroscopic methods. The known dammarane triterpenes ocotillone, eichlerianic ...

Rodrigues, Francisco A. P.; Prata, Mara M. G.; Oliveira, Iris Cristina Maia; Alves, Natacha Teresa Queiroz; Freitas, Rosa E. M.; Monteiro, Helena S. A.Nephrotoxicity is the main complication of gentamicin (GM) treatment. GM induces renal damage by overproduction of reactive oxygen species and inflammation in proximal tubular cells. Phenolic compounds from ginger, called gingerols, have been demonstrated to have antioxidant and anti-inflammatory effects. We investigated if oral treatment with an enriched solution of gingerols (GF) would promote a nephroprotect...
