The 192R/Q polymorphs of serum paraoxonase PON1 differ in HDL binding, lipolactonase stimulation, and cholesterol effluxs⃞

open access: yesJournal of Lipid Research, 2006
Serum paraoxonase (PON1) is a HDL-associated enzyme exhibiting potentially antiatherogenic properties. Here, we examined the common PON1-192R/Q human polymorphism. Despite numerous studies, the effect of this polymorphism on the antiatherogenic potential

Highly Stereoselective Alkylation of Spiro-γ-lactones

open access: yes, 2016
The alkylation of the (±)-spiro-γ-lactones 1 and 5a occurs with high diastereofacial selectivity. Geometry-optimized ab initio 4-31G calculations on enol 7 suggest that electrophilic attack occurs at an angle of about 80° to the plane of the enolate ...
