How to identify cis and trans isomers by nmr
WebThe affinity of a chiral drug to its target may significantly differ for enantiomers and diastereomers (Smith 1989;Singh et al. 2014). Stereoisomers may possess differential biological activity ... WebWith the trans isomer, a KAR-like conformation prevailed for ∼60% of the simulation time, compared with less than ∼10% of the time for the cis isomer (Figure S1A). In neither of these two simulations did the linker exclusively assume the KAR-like conformation, and the G-H linker conformation also fluctuated in our GluK2 control simulation (Sim. 7, Figure …
