all four enantiomers exhibited effects on end-plate current and miniature end-plate current decay at similar concentrations ( 0.2-1.0 mm ) , indicating that the measured effect was not related to the antibacterial action of the compounds in which d-threo chloramphenicol is known to be at least 50 times more powerful than the l-threo and d- and l-erythro isomers .
