An Aptamer‐Based EXACT Anticoagulant as a Sustainable, Animal‐Free Alternative to Unfractionated Heparin

Advanced Science, EarlyView.
By simply conjugating thrombin's active‐site inhibitor, dabigatran, with an exosite inhibitor, aptamer HD1, the resulting EXosite‐ACTive site (EXACT) inhibitors show two orders of magnitude higher potency and selectivity via synergistic binding, while maintaining the aptamer's antidote‐reversible trait, yielding a potential substitute for the animal ...

All‐Round Talent: Unique Zinc Guanidine Catalyst Performs Efficiently in Synthesis and Chemical Recycling of (Bio)Polyesters

Advanced Science, EarlyView.
A new zinc hybrid guanidine catalyst [Zn{(R,R)TMGNMe2(1,2)ch}2](OTf)2 (C1) shows very high catalytic activity in the polymerization of cyclic esters and in the depolymerization of these polyesters. Using C1 in the ring‐opening polymerization of lactide and caprolactone under industrially relevant conditions, astonishing rate constants of the same order
