Relaxant effects of the AMPK activators AICAR and A769662 and effect of the AMPK inhibitor compound C in rat renal interlobar arteries.
pEC50 (%) | Emax (%) | n | I1 (μm) | |
---|---|---|---|---|
A769662 | 4.92 ± 0.05 | 71.9 ± 5.7 | 6 | 308 ± 16 |
+ Compound C | 3.89 ± 0.15** | 43.5 ± 6** | 6 | 312 ± 16 |
AICAR | 2.67 ± 0.09††† | 61.8 ± 0,9 | 6 | 316 ± 17 |
+ Compound C | 1.79 ± 0.1* | 33.1 ± 13 | 6 | 326 ± 15 |
Values represent mean ± S.E.M. of the number n of individual arteries, 1–2 per animal. pEC50 is –logEC50, EC50 being the agonist concentration giving half-maximal relaxation; Emax = maximal relaxation (% Phe). Significant differences were analyzed by ANOVA or paired or unpaired Student t-test. *P < 0.05; **P < 0.01 versus control before treatment and †††P < 0.001 versus A769662.
