Toward Understanding the Mechanism of Client‐Selective Small Molecule Inhibitors of the Sec61 Translocon

Journal of Molecular Recognition, Volume 38, Issue 1, January 2025.
ABSTRACT The Sec61 translocon mediates the translocation of numerous, newly synthesized precursor proteins into the lumen of the endoplasmic reticulum or their integration into its membrane. Recently, structural biology revealed conformations of idle or substrate‐engaged Sec61, and likewise its interactions with the accessory membrane proteins Sec62 ...

Total Synthesis of the Anthelmintic Cyclodepsipeptide, PF1022A [PDF]

Bioscience, Biotechnology, and Biochemistry, 1994
The anthelmintic cyclooctadepsipeptide PF1022A and its antipode were synthesized starting from l-Nα-Boc-leucine (for PF1022A), d-Nα-Boc-leucine (for the antipode), l-lactic acid, and l-phenyllactic acid using Mitsunobu reaction and/or the DCC/HOBt method. The antipode had no anthelmintic efficacy.

Built-in 5-Aminooxazole as an Internal Activator of the Terminal Carboxylic Acid: An Alternative Access to Macrocyclodepsipeptides

CHIMIA, 2011
A conceptually novel macrolactonization technology is described. A strategically positioned 5-aminooxazole served as an internal traceless activator of the neighboring C-terminal carboxylic acid allowing the occurrence of macrolactonization ...
