Record Ca 2+The outer solution of passage stream contains the BaCl in mM 2, 10; TEA-Cl, 130; Glucose, 10; HEPES, 10; MgCl 2, 1, be buffered to PH7.3 with TEA-OH.With barium as charged particle carrier because this help flow point from and can avoid the inactivation that depends on calcium that flows.
Compound is dissolved among the DMSO, makes the liquid storage of 20mM.When the working concentration of medicine, not remarkably influenced of carrier (0.1%) Ca 2+Stream.
Total Test is finished under 21 to 24 ℃.Use List EPC-7 enlarger to write down whole stream of cells and store, digitizing is used based on the PC base software of similar above-mentioned scheme and below it is analyzed (Benham ﹠amp; Tsien, Journal of physiology(1988), 404,767-784).
The result
Ca 2+Stream
Use 10mMBa 2+Make charged particle carrier, the Ca that reaches 10nA of record dorsal root ganglion neurocyte 2+The peak pressure of passage current control.In per 15 seconds, make the fixed voltage-80mv of stream move to trial voltage 0 or 10mv.This pressure testing voltage is on the current-voltage characteristics peak, in this some assessment blocking-up, deducts any error due to the fixedly piezoelectricity drift.Some cells show stream to be weakened, as at Ca 2+That sees usually during stream is the same.Under collating condition, measure and weaken speed, in dispenser, infer to obtain and the relevant control value of the affected stream of medicament.The barrier effect of 3 minutes assessment 20 μ M medicines after the dispenser.
The compounds of this invention is to Ca 2+Levelling platform inhibiting rate is 30% to 100%.
