Mechanism-based Enzyme Inactivators of Phytosterol Biosynthesis

Molecules, 2004
Current progress on the mechanism and substrate recognition by sterol methyl transferase (SMT), the role of mechanism-based inactivators, other inhibitors of SMT action to probe catalysis and phytosterol synthesis is reported.

How and How Much Molecular Conformation Affects Electronic Circular Dichroism: The Case of 1,1-Diarylcarbinols

Molecules, 2018
Chiroptical spectra such as electronic circular dichroism (ECD) are said to be much more sensitive to conformation than their non-chiroptical counterparts, however, it is difficult to demonstrate such a common notion in a clear-cut way.

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.

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 ...

The Stereochemistry of Ketoreduction [PDF]

Chemistry & Biology, 2005
In this issue of Chemistry & Biology, Leadlay and coworkers report overproduction of a number of ketoreductase domains from modular polyketide synthases. These discrete enzymes allow the stereochemistry of polyketide ketoreduction to be studied in isolation.
