CW002 is a potent neuromuscular blocking drug that at doses up to 100 x ED95 produces modest hemodynamic effects that are not associated with bronchoconstriction or consistent histamine release.

These data indicate that oxidative/nitrosative stress associated with lung resection influences SERCA2a activity independent of any influence on protein expression or phospholamban phosphorylation. The findings link an acute event with a subcellular process primarily described for chronic illness and suggest a biochemical basis for perioperative changes in myocardial mechanical reserve.
