4. medicine preparation
Sodium azulenesulfonate (embodiment 16) and embodiment 1~embodiment 15 preparations are more created blue hydrocarbon azulene derivatives 5a~5h, 6a~6c, 7a~7b, 8a~8b use mass concentration 0.5% Xylo-Mucine (CMC) liquid to be mixed with the suspension confession experiment usefulness that concentration is 0.5 μ mol/mL respectively.
5. experimental technique
With sodium azulenesulfonate and target compound 5a~5h, 6a~6c, 7a~7b, 8a~8b are mixed with the suspension that concentration is 0.5 μ mol/mL with 0.5%CMC-Na respectively, and do blank (model group) and positive control respectively with 0.5%CMC-Na, omeprazole liquid (0.67mg/mL).Concrete experimental technique is: get Kunming mouse, and by the body weight random packet, 8 every group, male and female half and half.Model group gavages 0.5%CMC-Na liquid 0.4ml/20g; The omeprazole group gavages omeprazole liquid 0.4ml/20g; Sodium azulenesulfonate group and target compound group gavage soup 0.4ml/20g separately respectively.Below respectively organize mouse, be administered once every day, successive administration five days, and behind last administration 0.5h, each organizes mouse gavaging dehydrated alcohol 0.5ml, behind the 1h, puts to death mouse, dissects and gets stomach, cleans, and keeps the score according to the degree of pathology.What contrafluxion was rubescent is 1 minute, and petechial hemorrhage or erosion respectively are 1 minute, and rotten to the corn 1 of wire is 3 minutes.And carry out statistical study, calculate stomach ulcer mark and ulcer inhibition rate [ulcer inhibition rate=(model group stomach ulcer mark-administration group stomach ulcer mark)/model group stomach ulcer mark], and organize a significance difference relatively.Experimental result sees Table 1 and table 2.
(5a~5h is 6a) to the active influence of mouse gastric ulcer for table 1 target compound
dEach administration group and model group are relatively; * P<0.05.
Table 2 target compound (6b~6c, 7a~7b, 8a~8b) to the active d that influences of mouse gastric ulcer
dEach administration group and model group are relatively; * P<0.05.
From the data of table 1 and table 2 as can be seen, this type of of embodiment 1~embodiment 15 preparations more created blue hydrocarbon azulene derivatives 5a~5h, 6a~6c, 7a~7b, 8a~8b overwhelming majority has certain anti-gastric-ulcer activity, 5d wherein, 5h, 6b, 6c, 8a anti-gastric-ulcer ability is stronger more remarkable, with the model group contrast significant difference is arranged.
Experimental result shows, provided by the present inventionly more creates blue hydrocarbon azulene derivatives and can develop the anti-gastric-ulcer newtype drug with stronger pharmacologically active that makes new advances.
