EC50 and Emax values for agonist-stimulated 86Rb+ efflux in NGF-treated cells

Data are derived from the curves shown in Fig. 8 and are presented as the mean ± S.E.M. from three independent experiments.

Drug EC50Emax
μM % of Basal
Epibatidine 0.03 ± 0.003 311 ± 37
A-85380 7.0 ± 1.2 260 ± 5
DMPP 32 ± 17.1 125 ± 10a
Nicotine 33 ± 1.5 232 ± 23
Cytisine 42 ± 8.6 256 ± 21
Acetylcholine 118 ± 23 307 ± 24
Carbachol 379 ± 119 238 ± 43
  • a Emax for DMPP is significantly less than that for acetylcholine (p < 0.01).
