The bottleneck logic is worth restating because it explains when stacking helps at all: adding a second compound only matters if it clears a different rate-limiting step than the ones already covered
There is no completed head-to-head trial proving one is superior in the same population
The other consistent context in the preclinical literature is a metabolic environment the mouse studies pair the compound with diet/energy-balance conditions rather than testing it in isolation
Covalent functionalisation forms stable bonds via amidation, esterification, or silylation, ensuring durable conjugation for drugs, proteins, or imaging agents, whereas non-covalent approaches rely on stacking, electrostatic interactions, adsorption, or chelation, ensuring reversible binding, well-suited for stimuli-responsive delivery [33]
