Definitions
- the present invention relates to an intestinal polyp inhibitor.
- Intestinal polyps are elevated lesions of the intestinal epithelium, which are so-called warts that occur diffusely in the intestinal tract. Incidence varies from 1 to over 100, depending on the underlying condition. Pathologically, this includes various lesions ranging from benign neoplastic lesions such as hyperplastic lesions, dysplastic lesions, adenomas and adenocarcinoma to malignant neoplastic lesions. In particular, a clinical problem is that when the lesion becomes larger than 1.5 cm, it becomes partially malignant and becomes the mother of colorectal cancer in the future. For this reason, the intestinal polyp has been removed endoscopically, for example, by polybettomy using a colonoscope.

The basic feed “AIN-76A” (CLEA Ja pan) was used as the diet.
- wild-type C47BL / 6J mice purchased from the same company
- these mice were subjected to the same test.
- Compound A was used as a reagent. This food was mixed with AIN-76A, which is a basic feed, at a specified concentration (400 ppm or 800 ppm) and used for the test.
- a diet prepared by mixing a predetermined amount of a reagent reagent with a basic feed (AIN-76A) at a predetermined concentration was used to prepare experimental group mice (10 per group x 2 groups) and comparative group mice (10 per group). ) was administered for 13 weeks from 7 to 20 weeks of age (natural intake). However, if death is confirmed during the experiment, subsequent administration is naturally not performed.
- AIN-76A basic feed
- mice per group a group (10 mice per group) in which a basic feed (AIN-76A) to which no reagent was added was continuously provided for the same period as above was provided (group without administration of a reagent).
- mice There were 3 mice that died in the control group and 2 mice in the experimental group administered with the feed supplemented with 400 ppm of the reagent. All of these deaths were due to bleeding from polyps.
- Table 1 shows the results of examining the number of polyps per mouse in each group (average mouse SE of test mice). [0058] [Table 1]
- FIG. 1 shows the relationship between the number of polyps and the diameter, with the number of polyps per test mouse shown in Table 1 as the vertical axis and the diameter (mm) of the polyp as the horizontal axis. It is the calculated bar graph.
- black bars the result of the control group (test drug untreated group), open bars were fed a diet mixed with 400p P m of test agent 400ppm treated group (test agent The shaded bars are the results of the 800 ppm reagent group (the group fed with 800 PPm of the reagent).
- the two stars indicate the following.
- Compound A can exert the effect of decreasing the number of polyps in a dose-dependent manner at any dose.
- administration of Compound A resulted in all sizes of poly A decrease in the number of loops is observed. From this, it is considered that Compound A has the effect of delaying the polyp generation time and further suppressing the polyp growth itself.
- APC gene-deficient mice were used, so the impact on the initiation phase (time when DNA damage occurs) in human tumor development could not be evaluated. Compound A was released during the promotion phase (tumor progression time). It was suggested to be effective.
- the suppression of the number of large polyps (3 mm or more) shows a decrease in the number of polyps closer to the carcinogenic matrix, and it is considered that Compound A is also effective in suppressing the canceration of tumors.
- Compound A, as well as a general cancer prevention candidate drug has an action of suppressing tumor growth, and its usefulness as a cancer therapeutic agent is ignored.
- the intestinal polyp inhibitor of the present invention can prevent the occurrence of intestinal polyps, suppress the progression thereof, and exhibit a therapeutic effect by its administration, and is useful in the pharmaceutical field.
