Experimental example 1 Effect of continuous administration of drugs to rats on general Condition and food intake
1. Purpose of the test
The influence of the drug on the general state and food intake of rats after the continuous gavage administration of the rats for 14 days under the condition of equimolar dose is considered, and the prevention and/or treatment effect of each pharmaceutical composition on gastrointestinal adverse reactions caused by the compound A is further indirectly evaluated.
Capsule wall testing and preparation thereof
Example 1:
(1) Sample composition: 98.5mg of the compound A, 1.0mg of oxygen-containing clopidogrel oxide, 2.0mg of oxygen-containing clopidogrel isomer Z2 and 0.1mg of oxygen-containing clopidogrel enolate.
(2) Sample treatment: putting the materials into a clean administration container, adding a proper amount of Solutol for dissolving, carrying out spiral oscillation, adding pure water, carrying out ultrasonic treatment, and carrying out spiral oscillation until the compound is completely dissolved (for use in preparation).

Figure 354580DEST_PATH_IMAGE004
The above dose of administration: calculated as compound a. The multiple gavage dosing schedule for the groups of examples 2-18 and comparative examples 1-4 was the same as for the group of example 1.
\9355
The SD rats are male and female simultaneously and are randomly grouped into 10 rats each group; the effect of the drug on the general condition and food intake of the rats was observed and recorded after 14 consecutive days, once a day, with the corresponding drug or saline administered by gavage.
\9356
(1) In the general state study of rats 14 days after continuous gavage administration in each group, more than half of the rats in the example 1 group, the example 10 group, the example 15 group and the comparative examples 1 to 4 have hair erection, hypomotility and abdominal distension; no exception was found in the remaining example groups.
(2) The results of observing food intake of rats 14 days after continuous gavage administration in each group are shown in Table 3.
Figure 106636DEST_PATH_IMAGE005
Description of the invention: * P<0.01 vs blank group; ▲▲ p < 0.01 vs. comparative example 4.
As seen from Table 3, compared with the blank group, the rats of examples 2-9, 11-14 and 16-18 had food intake within 24 hours after the last administration substantially identical to that of the blank group, and had no statistical difference; in particular, examples 4, 5, 7, 8, 13, 14, 18 are relatively closer together. Compared with the group of the comparative example 4, the rats in the groups of the examples 2 to 9, 11 to 14 and 16 to 18 have very significant improvement of food intake within 24 hours after the last administration compared with the group of the comparative example 4, and have statistical difference (P < 0.01). On the other hand, the rats in the example 1 group, the example 10 group, the example 15 group and the comparative examples 1 to 4 had a very significant decrease in food consumption within 24 hours after the last administration compared with the blank group and had a statistical difference (P < 0.01).
The above results show that the composition has an unexpected improvement in the side effect of dyspepsia in the treatment of compound a when the amount of compound a or its salt is 97% or more and the amount of the compound a derivative is not more than 3%. Specifically, when the derivative in the composition is an oxygen-containing clopidogrel enolate and the content is not more than 0.5 percent, the composition has the effect of remarkably improving the side effect of dyspepsia; when the derivative simultaneously contains oxygen-containing clopidogrel oxide, oxygen-containing clopidogrel isomer Z2 and oxygen-containing clopidogrel enolate, and the dosage of the oxygen-containing clopidogrel oxide is not more than 0.5 percent, the dosage of the oxygen-containing clopidogrel isomer Z2 is not more than 2.0 percent, and the dosage of the oxygen-containing clopidogrel enolate is not more than 0.5 percent, the effect of obviously improving the dyspepsia side effect is better; especially, when the dosage of the oxygen-containing clopidogrel oxide is not more than 0.1%, the dosage of the oxygen-containing clopidogrel isomer Z2 is not more than 1.0%, and the dosage of the oxygen-containing clopidogrel enolate is not more than 0.1%, the pharmaceutical composition has the best effect of treating dyspepsia, and basically achieves the effect of completely curing dyspepsia side effects or the effect of completely avoiding the dyspepsia side effects of the compound A. When the amount of the derivatives exceeds the range, for example, the amount of the oxygen-containing clopidogrel oxide exceeds 0.5% (example 1 is about 1%), the amount of the oxygen-containing clopidogrel isomer Z2 exceeds 2% (example 10 is about 3%), or the amount of the oxygen-containing clopidogrel enolate exceeds 0.5% (example 15 is about 1%), the food consumption is remarkably reduced, and obvious digestive adverse reactions occur. In addition, when the composition of the present invention further comprises any one or more other derivatives, including but not limited to oxygen-containing clopidogrel isomer Z3, oxygen-containing clopidogrel isomer Z4, formula IIB in CN111150731A, and other impurities mentioned in patent WO2021070200A2, the efficacy of the above composition is not affected. That is, when the pharmaceutical composition of the present invention contains an oxygenated clopidogrel enolate, the kind of other derivatives does not affect the therapeutic and ameliorating effects of the composition of the present invention on dyspepsia, and the effect is the best when the composition contains an oxygenated clopidogrel enolate, an oxygenated clopidogrel isomer Z2, and an oxygenated clopidogrel oxide at the same time.
