چکیده

Recuperação relativa (Re) é uma das principais preocupações de microdiálise, uma técnica de amostragem acessível que pode coletar continuamente drogas livres no sangue e na maioria dos tecidos. Para uma determinada sonda de microdiálise, a recuperação de cada composto desta sonda está relacionada às características estruturais e propriedades físico-químicas se as condições experimentais estão estabelecidas. Neste trabalho, modelos de relação quantitativa estrutura-propriedade (QSPR) utilizando os métodos de regressão linear múltipla (MLR) e máquina de vetores de suporte (SVM) foram ajustados com o intuito de destrinchar relações de Re de microdiálise de compostos e seus descritores moleculares que capturam as características estruturais moleculares para uma série de derivados da flavona. Como resultado, parâmetros estatísticos significativos (modelo MLR: R = 0,9268 (coeficiente de correlação), QLOO = 0,8572 (variância explicada prevista) e Qext = 0,8639 (variância explicada externa), e modelo SVM: R 2 = 0,9383 e Qext = 0,8536) foram obtidos, indicando boa estabilidade e habilidade preditiva dos modelos. Assim, tornando viável prever as recuperações relativas na microdiálise de alguns compostos a partir de seus descritores moleculares. Este estudo foi uma tentativa inovadora e pode fornecer novos métodos para pesquisar a recuperação de microdiálise dos compostos.

Novel Atom-Type-Based Topological Descriptors for Simultaneous Prediction of Gas Chromatographic Retention Indices of Saturated Alcohols on Different Stationary Phases

In this work, novel atom-type-based topological indices, named AT indices, were presented as descriptors to encode structural information of a molecule at the atomic level. The descriptors were successfully used for simultaneous quantitative structure-retention relationship (QSRR) modeling of saturated alcohols on different stationary phases (SE-30, OV-3, OV-7, OV-11, OV-17 and OV-25). At first...
