Description

Technical Field

[0001] This invention relates to the field of pharmaceutical technology, specifically to a pharmacolactone III pharmaceutical composition for the prevention and treatment of ulcerative colitis and its application. Background Technology

[0002] Ulcerative colitis (UC) is a chronic, relapsing inflammatory bowel disease affecting the colonic and rectal mucosa. Clinical manifestations include diarrhea, mucus and bloody stools, etc., with a prolonged course that severely impacts patients' quality of life. Its pathogenesis is related to multiple factors, including inflammatory abnormalities and damage to the intestinal epithelial barrier. The pathological mechanism is complex, and current treatment options struggle to balance efficacy, safety, and long-term maintenance requirements.

[0003] Currently, the main clinical treatments for ulcerative colitis (UC) include 5-aminosalicylic acids, glucocorticoids, immunosuppressants, biologics, and JAK inhibitors. 5-aminosalicylic acids are first-line treatment for mild to moderate UC; those who do not respond well to them require glucocorticoids, while moderate to severe cases often require biologics or JAK inhibitors. However, these drugs all have significant limitations: 5-aminosalicylic acids may impair kidney function, requiring monitoring; TNF inhibitors carry risks of serious infections and malignancies; and JAK inhibitors carry risks of cardiovascular events and thrombosis, making them unsuitable for long-term UC treatment.

[0004] In the field of traditional Chinese medicine, Atractylodes macrocephala and its active ingredients have attracted attention due to their anti-inflammatory and intestinal mucosal protective effects. Reviews indicate that atractylodes lactone compounds have potential in treating ulcerative colitis (UC). However, existing technologies still have gaps: firstly, most UC-related TCM patents are compound formulas or extracts, with dispersed active substances, which is not conducive to quality control; secondly, research on atractylodes lactone III focuses on single mechanisms and lacks systematic efficacy evaluation; and thirdly, there is a translational gap between existing technologies and drug development, requiring the improvement of solutions based on single components that consider both efficacy and pharmaceutical feasibility. In response, we propose a atractylodes lactone III drug composition for the prevention and treatment of ulcerative colitis and its application. Summary of the Invention

[0062] Example 4

[0063] Application of a pharmacolactone III pharmaceutical composition for the prevention and treatment of ulcerative colitis

[0064] Preparation of Atractylodes lactone III Dosage Form

[0065] In this section, atractylodes lactone III (AT III) is used as the active ingredient, and 0.5% carboxymethyl cellulose solution is used as the drug delivery carrier to prepare a suspension or solution for oral administration.

[0066] The dosage concentrations of atractylodes lactone III in the low-dose, medium-dose, and high-dose groups were set at 5 mg / kg / d, 10 mg / kg / d, and 20 mg / kg / d, respectively. The dosage of the positive control group (5-ASA) was 400 mg / kg / d. The blank control group, the atractylodes lactone III monotherapy group, and the model group were all administered an equal volume of 0.5% carboxymethyl cellulose solution by gavage.

[0067] Verification of the application of atractylodes lactone III in the preparation of drugs for the prevention and / or treatment of ulcerative colitis

[0068] Laboratory animals and grouping

[0069] Seventy C57BL / 6 mice were selected and, after one week of acclimatization feeding, were randomly divided into seven groups of ten mice each, as follows:

[0070] Blank control group (Ctrl group);

[0071] Atractylodes lactone III monotherapy group (Ctrl+AT III group).

[0072] DSS-induced ulcerative colitis model group (Model group);

[0073] Positive drug group (5-ASA group);

[0074] Low-dose intervention group of atractylodes lactone III (AT III-L group).

[0075] Atractylodes lactone III medium-dose intervention group (AT III-M group).

[0076] High-dose intervention group of atractylodes lactone III (AT III-H group).

[0077] The feeding and handling of the laboratory animals were carried out in accordance with the National Laboratory Animal Welfare Guidelines and Laboratory Animal Ethics Standards.

[0078] Model building

[0079] Except for the Ctrl group and Ctrl+AT III group, which had normal access to drinking water, all other groups of mice had free access to distilled water containing 3% DSS for 7 consecutive days to establish a mouse model of ulcerative colitis.

[0080] Administration method

[0081] Drug intervention was administered concurrently during modeling. Specifically: the Ctrl group, Ctrl+AT III group, and Model group were administered 0.5% carboxymethyl cellulose solution by gavage; the 5-ASA group was administered 5-ASA solution by gavage; and the AT III-L group, AT III-M group, and AT III-H group were administered the corresponding dose of atractylodes lactone III solution by gavage. All groups were administered the medication by gavage for 7 consecutive days, once daily, with the administration time kept as consistent as possible.

[0082] Sample collection

[0083] On day 8, mice in each group were processed and samples were collected. Blood and colon tissue samples were collected from the mice, and the colon length was recorded. At the same time, the spleen and thymus were harvested and weighed for subsequent related indicator detection.

[0084] Effects of atractylodes lactone III on general symptoms and organ indicators in mice with ulcerative colitis

[0085] Disease Activity Index (DAI) Evaluation

[0086] During the modeling and drug administration period, the mental state, activity level, fur condition, fecal characteristics, and bloody stools of mice in each group were observed daily, and weight changes were recorded. The Disease Activity Index (DAI) was calculated based on weight loss, fecal characteristics, and degree of bloody stools.

[0087] Weight, colon length and immune organ index testing

[0088] Record the changes in body weight of mice in each group before and after the experiment. After sacrifice, the colon was dissected and its length was measured; at the same time, the spleen and thymus were dissected and weighed, and the spleen index and thymus index were calculated.

[0089] The experimental results showed that, compared with the Model group, the Atractylodes lactone III intervention group, especially the high-dose group, could significantly improve the increased disease activity index, weight loss, colon shortening and abnormalities in related immune organ indices in mice.

[0090] Effects of atractylodes lactone III on colonic tissue damage and mucosal barrier

[0091] HE staining

[0092] Colon tissue was collected, fixed, dehydrated, embedded, sectioned, and stained with hematoxylin and eosin (HE). The histopathological changes of the colon tissue were observed under a microscope, including but not limited to: the integrity of the mucosal structure; the degree of epithelial damage; the arrangement of glands; the degree of inflammatory cell infiltration; and the degree of damage to the mucosa and submucosa.

[0093] The experimental results showed that, compared with the Model group, the Atractylodes lactone III intervention group could reduce the destruction of colonic mucosal structure, inflammatory cell infiltration and tissue damage, with the high-dose group showing more significant improvement.

[0094] AB-PAS staining

[0095] Colon tissue sections were stained with AB-PAS to observe the number of goblet cells and mucus secretion, in order to evaluate the degree of damage to the colonic mucus barrier.

[0096] The experimental results showed that, compared with the Model group, the Atractylodes lactone III intervention group could improve the damage to the colonic mucus layer and enhance goblet cells and mucus secretion.

[0097] IHC staining

[0098] Colon tissue sections were obtained for immunohistochemical staining to observe changes in the mouse intestinal tight junction proteins Claudin-1, Occludin, and ZO-1.

[0099] Experimental results showed that intervention with atractylodes lactone III could improve intestinal barrier function damage in model mice, suggesting that it has a supporting effect on atractylodes lactone III in improving colon tissue damage.

[0100] Effects of atractylodes lactone III on oxidative stress-related indicators

[0101] The levels of superoxide dismutase (SOD) and catalase (CAT) were detected using commercially available kits, and the specific detection methods were performed in accordance with the kit instructions.

[0102] The experimental results showed that, compared with the Model group, the Atractylodes lactone III intervention group could improve the abnormal oxidative stress-related indicators in mice with ulcerative colitis, as evidenced by the recovery of SOD and CAT levels towards normal, with the high-dose group showing a more significant improvement.

[0103] Effects of atractylodes lactone III on inflammation and apoptosis-related markers

[0104] Inflammation-related marker testing

[0105] The expression levels of IL-6, IL-10 and TNF-α inflammation-related markers were detected by RT-qPCR.

[0106] The experimental results showed that, compared with the Model group, the Atractylodes lactone III intervention group could regulate the abnormal expression of inflammatory factors, suggesting that it has the effect of improving the inflammatory response of ulcerative colitis, with the high-dose group showing more significant improvement.

[0107] Apoptosis-related index detection

[0108] The expression changes of apoptosis-related markers in Bax and Bcl2 cells were detected by RT-qPCR.

[0109] The experimental results showed that, compared with the Model group, the atractylodes lactone III intervention group improved the abnormal apoptosis-related indicators, suggesting that atractylodes lactone III has a positive effect on alleviating colon tissue damage and improving cell apoptosis imbalance.

[0110] Effects of atractylodes lactone III alone on normal animals

[0111] Set up Ctrl+AT III group, administer atractylodes lactone III alone under normal drinking water conditions, and compare with blank control group to observe changes in general condition, weight, tissue morphology and related test indicators.

[0112] The experimental results showed that, compared with the blank control group, no significant adverse effects were observed when atractylodes lactone III was administered alone, indicating that atractylodes lactone III has a good basis for application under the administration conditions of this embodiment.

[0113] Summarize

[0114] In summary, atractylodes lactone III can be used to prepare drugs for the prevention and / or treatment of ulcerative colitis. In a DSS-induced mouse model of ulcerative colitis, atractylodes lactone III improved disease activity index, body weight change, colon length, and abnormalities in spleen and thymus indices; reduced colonic histological damage and mucus barrier disruption; and improved abnormalities related to oxidative stress, inflammatory response, and apoptosis, with higher doses showing more significant improvements. Furthermore, no significant adverse effects were observed when atractylodes lactone III was administered alone in normal animals, suggesting its potential application value.
