Test example 1:H1Receptor antagonism is tested
The active generally use guinea pig ileum shrinkage of compound antagonism H1 acceptors is tested to judge.By comparing guinea pig ileum
Contracted length, calculate the IC of inhibitory activity value50Value.
Cavy one is taken, its head is hit with mallet and puts to death, split abdominal cavity immediately, find ileocecus, at from ileocecus 1cm
Ileum is cut, one section of about 10cm or so ileum is taken out, is placed in the tyrode's solution culture dish for filling and being filled with air, intestines are removed along intestinal wall
Mesentery, ileum is then cut into several segments(Per 1~1.5cm of segment), draw tyrode's solution with 5mL syringes and rinse intestinal contents
Totally, change standby with fresh tyrode's solution.Pay attention to not pulling intestinal segment during operation in order to avoid influenceing contractile function.Take intestinal tube to be placed in and fill platform
In the culture dish of family name's liquid, at its both ends diagonal wall, threaded respectively with suture needle, and knot.Pay attention to keeping intestinal tube unobstructed, do not make it
Closing.Intestinal tube one end line is lain on ventilation hook hook, is then placed in 37 DEG C of Magnus' baths.With screw clamp regulation air pump gas outlet
Sebific duct, draft speed is escaped one by one with the bubble in Magnus' bath to be advisable.The other end of intestinal tube is added on pulling force transducing again
Device, and Muscle tensility is adjusted to appropriateness, preload 1g.After the stable 1h of Ileum From A White, after recording one section of normal contraction curve, successively
Agents are added dropwise in Magnus' bath.After adding 0.3 μ g/mL histamine 0.1mL, contact 2 minutes, and observe shrinkage amplitude, so
Afterwards with tyrode's solution continuous flushing for several times, the level before baseline restorer to medication is treated, then records one section of baseline.Plus 10- then
5mol/L histamine solution, each 0.1mL is continuously plus until intestinal contraction reaches maximum.(Due to histamine work have it is certain
Hysteresis quality, so to be added when adding every time at the preceding second largest value once shunk.)Then elute for several times, treat baseline restorer
Originally height adds testing sample, is incubated 15min, then adds 10-5mol/L histamine solution as previously described.It should be noted that addition group
The amount that the total amount of amine should be added with last time is consistent.The compound of table 1 suppresses the IC that guinea pig ileum shrinks activity50。
The compound of table 1 suppresses the IC that guinea pig ileum shrinks activity50

The compounds of this invention suppresses the IC that guinea pig ileum shrinks activity50Value is below astemizole, but above Ground chlorine thunder he
It is fixed, show that the compounds of this invention suppresses guinea pig ileum and shrinks activity by force.Illustrate that compound has stronger antagonism H1The work of acceptor
Property.
Test example 2:To the antiasthmatic effect of asthmatic guinea pigs caused by histamine
Cavy is taken, is placed in lucite bell jar, ultrasonic atomizatio sprays into salt histamine solution (0.8mg/mL) 40s, record cavy production
The time of raw asthma, using the time twitched, fallen as incubation period, the cavy more than 180s is not selected, by the cavy selected with
Machine is grouped, every group 10, Normal group, Desloratadine group (1mg/kg), testing compound group (0.1mg/kg).With 2mL/
Kg bw gastric infusions, 60min after administration, are respectively put into glass bell jar, by similarity condition spraying histamine hydrochloride during pre-selection
Solution, in the incubation period that record asthma occurs, if not occurring asthma person yet more than 6min, in terms of 6min, as a result carry out at statistics
Reason.Its result is as shown in table 2:
Table 2 be test compound antiasthmatic effect result (, n=10)
Compound number | Incubation period before administration(s) | Incubation period after administration(s) |
Normal group | 108.2±38.4 | 117.9±42.3 |
Desloratadine group | 116.7±35.9 | 261.4±43.1* |
KZAL1206 | 106.3±35.9 | 264.4±41.6* |
KZAL1209 | 112.0±32.6 | 259.4±38.2* |

KZAL1235 | 107.6±36.6 | 260.7±47.6* |
* compared with Normal group:P<0.05, # compared with Desloratadine group:P<0.05
60min after the compounds of this invention administration, gives histamine hydrochloride solution, is hidden before finding the incubation period relatively administration that asthma occurs
Phase extends, and incubation period is noticeably greater than in the case that the compounds of this invention dosage is Desloratadine group 1/10, after administration
Loratadine group has KZAL1210 and KZAL1222, KZAL1206, KZAL1209 and KZAL1235 and Desloratadine group phase
Than no significant difference.Illustrate that the compounds of this invention antiasthmatic effect is suitable or more excellent with Desloratadine.
Test example 3:The influence of cell proliferation activity
Influence of the MTS methods detection compound to RAW264.7 cell-proliferation activities.Cell is inoculated in 96 orifice plates, sets blank respectively
Control group, compound group (10 μ g/ mL and 100 μ g/mL various concentrations), every group sets three multiple holes.Add the μ L of MTS solution 20 per hole,
1-2 hours are incubated, its light absorption value is surveyed under the conditions of wavelength 490nm using ELIASA.It was found that compound group(Two concentration)With it is right
According to group absorbance without significant difference, illustrate that the compounds of this invention does not interfere with the proliferation activity of RAW264.7 cells.
Above-mentioned pharmacological testing shows that compound of the invention is respectively provided with excellent antagonizing histamine function of receptors, has excellent
Antiasthmatic activity, have more plus depth research and development potentiality.
