Description

Composition containing piperine for preventing, improving or treating cancer cachexia containing piperine

The present invention relates to a composition for preventing, improving or treating cancerous cachexia containing piperine.

Cachexia refers to a complex syndrome that causes persistent muscle loss caused by various diseases such as cancer, heart failure, chronic obstructive pulmonary disease, chronic kidney disease, AIDS, and the like. Among them, cancer cachexia is a complex metabolic syndrome accompanied by malignant tumors, and is defined as a loss of more than 5% of body weight due to muscle and fat loss within 6 months of the onset of cancer. Cachexia can occur in a variety of medical conditions, but cancerous cachexia is closely related to terminal cancer. About 50% of all cancer patients, especially about 80% of terminal cancer patients, are affected by cancerous cachexia and suffer from reduced life and increased mortality due to loss of muscle and fat. Cancer cachexia is characterized by weight loss through significant loss of muscle mass and adipose tissue, and has different characteristics from muscle and fat loss through appetite suppression.

The diagnostic criteria for cancer cachexia include a reduction in weight loss of 5% or more, high levels of inflammatory marker expression in serum levels (IL6, CRP1, TNFr), decreased exercise capacity, and anorexia. Although the exact mechanism of cancer cachexia is not known, inflammatory cytokines such as IL-6, TNF-α, and C-reactive protein 1 (CRP1) are known to play a central role in muscle and fat loss.

Skeletal muscle weight loss and muscle wasting due to the inflammatory response activate the ubiquitin-proteasome proteolytic pathway and the autophagic/lysosomal proteolytic pathway, and muscle protein is degraded. In particular, increases in ubiquitin ligases such as MAFbx/Atrogin-1 (muscle atrophy F-Box) and MuRF1 (muscle RING finger-1) and autophagy-related genes such as Bnip3 It is directly involved in proteolysis.

Treatments for cancer cachexia include NSAIDs (non-steroidal anti-inflammatory drugs), β2-adrenergic agonists, corticosteroids, and ghrelin. There are α inhibitors.

A COX-2 inhibitor is a drug that reduces the loss of skeletal muscle by inhibiting COX-2, which is involved in the production of prostaglandins, which are inflammatory substances generated in large amounts in cancer tissues. As a COX-2 inhibitor, celecoxib is commercially available. However, side effects such as anemia, gastric ulcer, allergy, heart attack and stroke have been reported with celecoxib.

A TNF-α inhibitor is a drug that kills cancer cells by reducing the expression of TNF-α, which is often expressed in the bloodstream of patients with cancer cachexia. Thalidomide is commercially available as a TNF-α inhibitor. However, these drugs have little effect as a treatment for cancer cachexia, and have side effects such as depression, heart failure, shortness of breath, vomiting, rash, high blood pressure, and birth defects during pregnancy.

As such, most of the drugs being developed or marketed up to now have many side effects and lack of evidence for their therapeutic effect. Therefore, there is an urgent need to develop a treatment for cancer cachexia with a new mechanism.

On the other hand, piperine (C ₁₇ H ₁₉ NO ₃ ) is an alkaloid used as a spice. It has also been used as a herbal medicine with a warming effect.

The present inventors have completed the present invention by confirming that a piperine compound, which is a component derived from a natural product, particularly a food, has a significant improvement in cancerous cachexia in a mouse model in which cancer cachexia is induced by injection of CT26 cells.

The normal control group was not injected with anything.

After 1 week of induction of cancerous cachexia (A) Normal control group (NC) injected with PBS for an additional 4 weeks, (B) Disease control group (CC) injected with PBS for an additional 4 weeks and (C) Piperine (10 mg/day) for additional 4 weeks kg/day), the experimental group (CC+Pi) was treated differently and the experiment was carried out. At this time, piperine was purchased from Sigma Aldrich (catalog number: p49007) and used.

<Example 2> The effect of piperine on weight loss improvement due to cancerous cachexia

To confirm the induction of cancerous cachexia and the improvement effect of piperine, the weight of the mice was measured after treatment for a total of 5 weeks in the same manner as in Example 1 above. In addition, in order to correct for the difference in body weight according to cancer tissues, the cancer free body weight was compared from the total body weight of the mice minus the weight of the cancer tissues.

The results of testing the effect of piperine on the inhibition of weight loss caused by cancerous cachexia are shown in FIG. 1 .

As a result, there was no significant change in the total body weight including the cancer tissue (Fig. 1 left, body weight), but when piperine was treated (CC+Pi), the weight decreased in the body weight excluding the cancer tissue (Fig. 1 right, cancer free body weight). showed improvement. Therefore, it was confirmed that piperine significantly inhibited the weight loss induced by cancer cachexia compared to the disease control group (CC).

<Example 3> Effect of Piperine on Expression Improvement on Cancer Cachexia Indicator Factor

After a total of 5 weeks of treatment in the same manner as in Example 1, blood was collected from mice, and serum was separated using a centrifuge at 4000 RPM, 4° C., and 20 minutes, followed by IL-6, CRP, TNF- Serum was added to the α-coated plate and reacted, followed by reaction with a secondary antibody, and the difference in color according to the expression level was analyzed using an ELISER analyzer (VERSAmax microplate reader, Molecular Devices, CA, USA).

Figure 2 shows the results of an experiment on the effect of piperine on changes in inflammatory cytokines that occur in the process of cancerous cachexia.

As a result, it was confirmed that piperine showed an improvement effect on changes in inflammatory cytokines induced by cancer cachexia in all of serum CRP, serum TNF-α and serum IL-6.

<Example 4> Effect of piperine in inhibiting muscle tissue reduction due to cancerous cachexia

In order to confirm the induction of cancerous cachexia and the improvement effect of piperine, the gastrocnemius muscles (GAS) and tibialis anterior muscles (TA) muscle tissues of mice after a total of 5 weeks of treatment in the same manner as in Example 1 above The volume and weight of the were measured.

The results of the experiment on the effect of piperine on the inhibition of muscle tissue reduction are shown in FIG. 3 .

As a result, it was confirmed that piperine significantly inhibited the reduction of muscle tissue TA and GAS due to cancerous cachexia, and showed an improvement effect on both tissue volume (left side of FIG. 3 ) and weight (right side of FIG. 3 ).

<Example 5> Inhibitory effect of piperine on reduction of adipose tissue due to cancerous cachexia

In order to confirm the induction of cancerous cachexia and the improvement effect of piperine, the volume and weight of adipose tissue (iWAT; inguinal white adipose tissue) of mice were measured after treatment for a total of 5 weeks in the same manner as in Example 1 above.

The results of the experiment on the effect of piperine on the inhibition of adipose tissue reduction are shown in FIG. 4 .

As a result, it was confirmed that piperine significantly inhibited the reduction of iWAT, which is an adipose tissue, due to cancerous cachexia, and showed an improvement effect on both the tissue volume (left side of FIG. 4) and weight (right side of FIG. 4).
