[1] The authors reported that methylquinolinium analogs with primary-amine substitutions displayed high permeability from passive and active transport across membranes, measured using two standard in-vitro models: the parallel artificial membrane permeability assay (PAMPA) and Caco-2 human intestinal cell monolayers
For example, no reaction occurs between neopentyl chloride and B 12s , whereas the secondary alkyl halide analogs are too unstable to be isolated
