From SAR to comparative QSAR: role of hydrophobicity in the design of 4-hydroxy-5,6-dihydropyran-2-ones HIV-1 protease inhibitors

Role of hydrophobicity in the design of 4-hydroxy-5,6-dihydropyran-2-ones—a new class of emerging HIV-1 protease inhibitors (HIV-PI) was investigated by using comparative QSAR. These studies show that most of the data points in the individual dataset studied fall either on positive or negative side of the optimum value of Clog P. This is why, we observe either a positive or negative Clog P term in the QSAR. To observe the optimum value of Clog P for these inhibitors, a sufficient spread in the data is required. It is hoped that the results of this study would help in optimizing substituents for better binding at enzyme pockets and guide in the design of more effective HIV-PI of this class.

In the present study, the role of hydrophobicity in the design of 4-hydroxy-5,6-dihydropyran-2-ones HIV-1 protease inhibitors is discussed. It has been found that a sufficient spread in the data is required to observe the optimum value of Clog P for these inhibitors.Figure optionsDownload as PowerPoint slide
