An asymmetric synthesis of nelfinavir is described starting from acrolein and (S)-methyl phenyl sulfoxide. The key features include (a) stereoselective preparation of a beta-protected amino-gamma,delta-unsaturated sulfoxide by the reaction of an alpha-sulfinyl carbanion with an unsaturated t-butyl sulfinylimine, (b) stereoselective

A general linear solvation energy equation has been used to analyze published partition coefficients in the systems water-octanol (613 solutes), water-hexadecane (370 solutes), water-alkane (200 solutes), and water-cyclohexane (170 solutes). The descriptors used in the equation are R2, an excess

Endocytosis is critical for many cellular functions. We show that endocytosis of the common gammac cytokine receptor is clathrin independent by using a dominant-negative mutant of Eps15 or RNA interference to knock down clathrin heavy chain. This pathway is synaptojanin
