Allosteric regulators are known to affect caspase enzyme activity, in general, by facilitating large conformational changes that convert the active enzyme to a zymogen-like form in which the substrate-binding pocket is disordered. Mutations in presumed allosteric networks also decrease activity, although large structural changes are not observed.

Therefore, we evaluated the stability of amoxicillin in those medical devices, with particular focus on both drug concentration and storage temperature. Stability of 20, 40, and 60g/L amoxicillin solutions in 300 mL portable pumps stored at 20 or 35 degrees C was studied by visual examination and drug concentration measurements at T0; T0 + 12 h; T0 + 24 h and; T0 + 48 h.
