Ceramide structural features required to stimulate ABCA1-mediated cholesterol efflux to apolipoprotein A-I

Journal of Lipid Research, 2006
Ceramide is a component of the sphingomyelin cycle and a well-established lipid signaling molecule. We recently reported that ceramide specifically increased ABCA1-mediated cholesterol efflux to apolipoprotein A-I (apoA-I), a critical process that leads ...

Stereochemistry of N-Acyl-5H-dibenzo[b,d]azepin-7(6H)-ones

Molecules, 2023
The stereochemical properties of N-acyl-5H-dibenzo[b,d]azepin-7(6H)-ones (2a–c), which inhibit potassium channels in T cells, were examined by freezing their conformational change due to 4-methyl substitution.

An efficient approach to mechanically planar chiral rotaxanes

, 2014
We describe the first method for production of mechanically planar chiral rotaxanes in excellent enantiopurity without the use of chiral separation techniques and, for the first time, unambiguously assign the absolute stereochemistry of the products ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
