Semi-quantitative and quantitative structure–taste relationships for carboand hetero-sulphamate (RNHSO3) sweeteners

Abstract: Seventeen carbosulphamates (eight syqthesised in this study) and 23 heterosulphamates (seven synthesised here) have been examined with a view to extending previously developed ' r 2 structuretaste relationships for sulphamates (RNHSO;).Measurements of defined parameters x, y, z, and V ( V = xyz) for R using Corey-Pauling-:'oltun space-filling models for the 17 carbosulphamates have shown that their taste can be predicted in most cases using the previously developed semi-QSAR established. Predictions made from … Show more

“…In previous work we have had some success in deriving structure-taste relationships (SARs) for the first 33 compounds, 10 then 56 compounds, 11 and more recently 101 compounds. 12 Each data set was examined using the Corey-Pauling-Koltun (CPK) parameters for the RNH portion of the heterosulfamate i.e.…”

“…The mathematical techniques of linear discriminant analysis (LDA) 10,11,12 and quadratic discriminant analysis (QDA) 10,11,12 and, more recently, Tree analysis 12 have been employed in studying the data sets. The LDA and QDA analysis worsened somewhat as the size of the data set grew and thus Tree analysis was introduced to try to improve the classifications.…”

“…Para enfrentar estos inconvenientes, los químicos han desarrollado modelos matemáticos basados en la teoría QSAR/QSPR con la finalidad de predecir el dulzor de los compuestos y optimizar la síntesis los mismos. Además de los modelos QSAR previamente descritos para los gustos dulce-amargo, se han propuesto otros modelos que buscan discriminar entre compuestos dulces y no dulces de carbosulfamatos (Miyashita et al, 1986a;Okuyama et al, 1988) y otros derivados del sulfamato (Spillane & McGlinchey, 1981;Spillane & Sheahan, 1989;Spillane & Sheahan, 1991;Spillane et al, 1993;Spillane et al, 2000;Spillane et al, 2003;Spillane et al, 2009).…”

“…En la Tabla 5.12 se presentan los diversos modelos QSAR desarrollados para discriminar moléculas dulces y no dulces. En la mayoría de los casos estos modelos se han establecido mediante el uso de bases de datos con familias de compuestos homogéneas (Iwamura, 1980;Kier, 1980;Spillane & McGlinchey, 1981;Takahashi et al, 1982;Spillane et al, 1983;Takahashi et al, 1984;Miyashita et al, 1986a;Miyashita et al, 1986b;Okuyama et al, 1988;Spillane & Sheahan, 1989;Spillane & Sheahan, 1991;Spillane et al, 1993;Drew et al, 1998;Spillane et al, 2000;Spillane et al, 2002;Spillane et al, 2003;Spillane et al, 2009). Este hecho limita la generalización de tales modelos a diferentes tipos de compuestos, es decir, el dominio de aplicabilidad de los mismos es restringido.…”
