In vitro binding of chloroquine to rat muscle preparations.


Chloroquine (7-chloro-4-[[4-(diethylamino)-1-methylbutyl]amino]quinoline; CQ) accumulates in the insoluble fraction of rat muscle homogenates with an equilibrium distribution ratio of 7.8 L/kg. This is of a similar magnitude to muscle:plasma ratios observed in vivo. Uptake is approximately linear, even up to concentrations of free CQ greatly exceeding toxic… (More)
