Cholesterol absorption inhibition remains an attractive approach for the treatment of hypercholesterolemia. We have continued our SAR development in the spirostanyl cellobioside class of agents seeking a greater understanding of the role carbamoyl substitution has on the potency in this series. In this regard, a series of differentially substituted carbamate analogs were made with and without deoxygenations. From this study, it was determined that the minimal requirements for optimal potency was a lone carbamate at C4" and deoxygenation at the C6" position.
