The macrocyclic effect in tetraaza-macrocyclic ligands
Inorganica Chimica Acta, 1980Abstract The origin of the Macrocyclic Effect [1] in complexes of cyclam as compared with those of its open-chain analogue 2,3,2- tet is discussed. It is not readily apparent that the presence of four secondary (2°) nitrogens in cyclam , as opposed to two primary (1°) and two 2° in 2,3,2- tet should make much difference, since the pK a 's of 2 ...

Reversible Macrocycle-to-Macrocycle Interconversion Driven by Solvent Selection
Journal of the American Chemical Society, 2023Macrocycle-to-macrocycle interconversions are of interest because they can allow access to a variety of structures. However, reversible interconversion between different sized macrocycles remains challenging to control. Herein, we report a facile one-pot synthesis of a series of self-assembled macrocycles from readily prepared α,α'-linked oligopyrrolic

Macrocyclic Proteasome Inhibitors
Current Medicinal Chemistry, 2011Proteasome inhibitors have proven to be effective anticancer agents. Despite the success of the first on the market proteasome inhibitor bortezomib in chemotherapy, alternative clinically useful proteasome inhibitors are still urgently needed as bortezomib therapy causes severe side effects and is limited by arising drug resistance.

Application of Ruthenium-Induced Macrocyclization for the Construction of Macrocyclic Depsipeptides
The Journal of Organic Chemistry, 2002The synthesis of a biaryl ether containing macrocyclic depsipeptide 1 was achieved in 6% overall yield. The desired macrocycle was constructed by cyclization of a phenol into eta(6)-ruthenium complex. The ruthenium metal was subsequently photolytically deprotected to obtain the macrocycle 1.
