Chirální separace acyklických nukleosid fosfonátů a stanovení asociačních konstant jejich komplexů s cyklodextriny kapilární elektroforézou
Capillary electrophoresis (CE) has been applied to the chiral separation of acyclic nucleoside phosphonates, which belong toof the most important already registered or potential antiviral drugs. For enantioseparation of acyclic nucleoside phosphonates, the following native and derivatized cyclodextr...
