cationic

It looks like four amphetamines because those two cationic isomers are in salts with two different anions.

Nicotine fairly specifically binds to the cholinergic nicotinic gating site on cationic ion channels in receptors throughout the body.

Anionic and cationic detergents are more harmful than nonionic detergents (54), and increased concentrations of surfactant result in more rapid, severe damage (55).

They're also cationic [1], so they bind anionic lipids in bacteria and mitochondria that aren't found (in large quantities) on the mammalian cell surface.

Specifically, they have developed ionizable cationic lipids with pKa below 7 to encapsulate the 'package' at a low pH, while maintaining a relatively neutral surface charge at physiological pH.

But upon reflection, it's arguable that the paper would have been more interesting if they had included L-canavanine, in addition to L-arginine and three analogs with shorter cationic side chains.

It can go from a simple aspirin[3] (baby-aspirin anyone?), to the dangerous DNP in a low-dose, controlled release formulation[4], the novel cationic uncouplers [5], or the safe mitoBHT [6].

My first idea was that some of the pesticides in different medications might block or interact with each other, which is the reason why you usually get conditioner and shampoo in two bottles (the chemicals in most conditioners are cationic while the ones in shampoos are anionic) Having now looked through quite a few Wikipedia articles of the pesticides used, I can't find no such statements...

A very interesting material as a cationic hydrocarbon iodide "salt".

>Cationic polymers are a promising class of bioactive agents, which trigger bacterial cell death through physical disruption of their membranes.
