Abstract:
The synthesis and biological activities of four novel bispyridinium cyclophanes as choline kinase (ChoK) inhibitors are presented. Their synthetic methodology has been optimized according to dilution, temperature, and reaction time and provides pure bispyridinium cyclophanes in high yields very easily. One of these cyclophanes (6, 4,8-diaza-3(1,4),9(4,1)-dipyridina-1(1,4),6(1,3)-dibenzenacyclodecaphan-3(1),9(1)-bis(ilium) dibromide) has an IC(50(ChoK)) of 0.3 microM and is the most potent human ChoK inhibitor described to date.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
