Abstract:
Immunofluorescent microscopy of cancer cells A549 treated with novel alicyclic (mostly bridged) podophyllotoxin C4-esters at different concentrations gave evidence that the ‘curling’ of microtubules occurred at one of the first steps of their depolymerisation. Molecular dynamics study revealed the differences in curved conformations of tubulin dimer in a complex with adamantane-comprising ester and in a complex with podophyllotoxin.
