Description of the Method of hBK1 Receptor Binding
CHO cells expressing the hBK1 receptor are cultivated in Dulbecco's modified medium. The medium from confluent cultures is removed and the cells are washed with PBS buffer, scraped off and isolated by centrifugation. The cells are then homogenized in suspension and the homogenate is centrifuged and resuspended. The protein content is determined and the membrane preparation obtained in this manner is then frozen at −80° C.
After thawing, 200 μl of the homogenate (50 to 100 μg of proteins/assay) are incubated at room temperature with 0.5 to 1.0 nM of kallidin (DesArg10, Leu9), [3,4-prolyl-3,43H(N)] and increasing concentrations of the test substance in a total volume of 250 μl for 60 minutes. The incubation is terminated by rapid filtration through GF/B glass fibre filters which had been pretreated with polyethyleneimine (0.3%). The protein-bound radioactivity is measured in a TopCount NXT. Non-specific binding is defined as radioactivity bound in the presence of 1.0 μM of kallidin (DesArg10, Leu9), [3,4-prolyl-3,43H(N)]. The concentration/binding curve is analysed using a computer-assisted nonlinear curve fitting. The K which corresponds to the test substance is determined using the data obtained in this manner.

A solution of lithium aluminium hydride (2N in THF), which had previously been diluted with 2 ml of anhydrous THF, was carefully added dropwise to a solution of the product of Example 706c) (132 mg, 0.44 mmol) in 3 ml of anhydrous THF, while cooling. Then the mixture was slowly heated and then the reaction mixture was refluxed for 4 hours. It was then cooled to −5° C. and 1 ml of a 1N sodium hydroxide solution was added dropwise. The precipitate formed was filtered off and washed with approx. 5 ml THF and then with methanol. The combined organic solutions were dried on sodium sulphate and then evaporated down. The product thus obtained was reacted further without purification.
