A quantitative Structure-Activity study is performed on several series of compounds derived from N-chlorosulfonyl isocyanate to develop models that their structures to IC50 activity for inhibition of acyl-CaA:cholesterol O-acyltransferase (ACAT). The values of log IC50 of the studied compounds were well correlated with the descriptors encoding the chemical structures. Considering the pertinent descriptors, a correlation coefficient of 0.9592 (s = 0.2334, n = 59) was obtained for the MLR model.

Keywords: MLR; QSAR; N-Chlorosulfonyl isocyanate; Cholesterol; IC50 activity; Descriptors.
