A new cyclodextrin-based antidote?

Posted by

Jelly fish poisoning, overdose of neuromuscular blockades and anticoagulants.

What do they have in common?

Cyclodextrins can work as antidotes in all cases.

This current article describes a new CD derivative as a potential UNIVERSAL reversal agent for anticoagulants.

OKL-1111 concentration-dependently reversed the in vitro anticoagulant effects of dabigatran, rivaroxaban, apixaban and edoxaban in the thrombin generation assay. Not to mention, that OKL-1111 also reversed the anticoagulant effect of the vitamin K antagonist warfarin, the low molecular weight heparin enoxaparin, the pentasaccharide fondaparinux and the platelet inhibitor clopidogrel in vivo.

But what is this magical molecule?

It is a modified gamma-cyclodextrin substituted at the 6th position with 6-mercaptohexanoic acid. Seems familiar? Maybe, but it is also unique in its way.
