+The relation that competition suppresses.
4-3: the reversibility of inhibition
The method test The compounds of this invention is machine-processed to the active inhibition of proton pump by so-called dilution (Dilution) with (Washout), (referring to D.J.Keeling, et al., Biochemical Pharmacology 42 (1), 123-130 (1991).
That is, test tube is divided into two groups, first group and second group of compound of making for the DMSO and the embodiment of the invention 34 respectively separately.The compound (6 μ M) that DMSO and the embodiment 34 of 10 μ l made adds first group and second group respectively.
In all two groups, add 100 μ l by embodiment 4-1, the freeze drying bone magenblase that when concentration is 100 μ g albumen/1ml, makes.Then, in the 3rd group, add 5m MPipes/Tris damping fluid (pH 6.4), reach 150 μ l until its test tube volume.Behind the preincubate 15 minutes, press step measurements H identical among the embodiment 4-2

After preincubate is finished, with 50 times of each group dilutions, use centrifugal 60 minutes of Beckman ultracentrifuge (L8-80 type) then with 5mM Pipes/Tris damping fluid (pH 6.4).Abandon supernatant liquor, throw out is suspended in (pH 6.4) reach identical with the volume of preincubate until its volume in the 5m MPipes/Tris damping fluid.After this, press the identical step measurements (H described in the embodiment 4-2
+/ K
+The inhibition of)-atpase activity; Fixed by step 1 pacing same as described above again, just azoles and SK﹠amp are drawn in Australia U.S.A; F96067 is as the contrast material.Carry out before or after described dilution and the flushing; H
