Aminooxyacetic acid (AOAA) is known as a CBS inhibitor (Asimakopoulou et al., 2013; Whiteman et al., 2011). Propargylglycine (PAG) and β-cyano-l-alanine (BCA) are used to inhibit CGL activity (Asimakopoulou et al., 2013; Whiteman et al., 2011). However, no selective inhibitor ...
13.An optically active N-(α-mercaptopropionyl)glycine, being levo or dextro N-(α-mercaptopropionyl)glycine;wherein:the levo N-(α-mercaptopropionyl)glycine is S-(−)-N-(α-mercaptopropionyl)glycine:of S-configuration, or a pharmaceutically acceptable salt or ester thereof; andthe dextro N...
Assuming these cyclopeptides to occur in a hydrogen-bonded pleated sheet structure, certain dominant changes in the spectra are interpreted as reflecting a transition of the overall backbone conformation from one which is closer to the (optically inactive) symmetry Ci to another which is closer to ...
A variant is the hetero-Diels–Alder (HAD), in which either the diene or the dienophile contains a heteroatom, usually nitrogen or oxygen. The asymmetric HDA reaction is among the most efficient available methodologies for the preparation of optically active six-membered heterocycles.51d,e In 198...
It also appears that antimicrobial activity is decreased with increasing achiral residues, an effect that could be due to the reduced hydrophobicity and decreased organizational structure of the helix. The sequence containing all Nsdp residues is relatively inactive, but that containing 4 Nsdp residues ...
optically inactive j. achiral Consider an enzyme containing an iron-sulfur cluster (which is very common among metalloenzymes) where the atoms of each type are arranged at the corners of a cube. Let us model an electron within this...
