چکیده

No presente estudo o linoleato de metila ozonizado com índice de peróxidos de 1.800 mmol-equiv. kg foi caracterizado quimicamente. Os efeitos do ozônio sobre o linoleato de metila produz hidroperóxidos, ozonideos e aldeídos, os quais foram identificados por técnicas de ressonância magnética nuclear de H e C, monoe bidimensional. O linoleato de metila padrão e o linoleato de metila ozonizado mostram espectros muito similares, excetuando os valores de ressonância (δ 9,7 e δ 9,6) que correspondem aos hidrogênios aldeídicos (δ 5,7 e δ 5,5) e olefínicos de hidroperóxidos (δ 5,2). Outras atribuições estão baseadas nas conectividades fornecidas pelas constantes de acoplamento. Estes resultados indicam que a espectrometria de RMN pode oferecer informação valiosa a respeito da quantidade de compostos oxigenados formados à partir do linoleato de metila ozonizado para o uso em ozonoterapia e na química de óleos vegetais ozonizados.

Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led to an ongoing search for potent broad spectrum antifungal agents with low side effects, which can be administered both orally and parenteral...
