  • Objectives : While treatments for cancer are advancing, the development of effective treatments for cancer metastasis, the main cause of cancer patient death, remains insufficient. Recent studies on Dichroae Radix have revealed that its active ingredients have the potential to inhibit cancer metastasis. This study aimed to investigate the cancer metastasis inhibitory effect of Dichroae Radix using network pharmacological analysis. Methods : The active compounds of Dichroae Radix have been identified using Traditional Chinese Medicine System Pharmacology Database and Analysis Platform. The UniProt database was used to collect each of information of all target proteins associated with the active compounds. To find the bio-metabolic processes associated with each target, the DAVID6.8 Gene Functional classifier tool was used. Compound-Target and Target-Pathway networks were analyzed via Cytoscape 3.40. Results : In total, 25 active compounds and their 62 non-redundant targets were selected through the TCMSP database and analysis platform. The target genes underwent gene ontology and pathway enrichment analysis. The gene list applied to the gene ontology analysis revealed associations with various biological processes, including signal transduction, chemical synaptic transmission, G-protein-coupled receptor signaling pathways, response to xenobiotic stimulus, and response to drugs, among others. A total of eleven genes, including HSP90AB1, CALM1, F2, AR, PAKACA, PTGS2, NOS2, RXRA, ESR1, ESR2, and NCOA1, were found to be associated with biological pathways related to cancer metastasis. Furthermore, nineteen of the active compounds from Dichroae Radix were confirmed to interact with these genes. Conclusions : The results provide valuable insights into the mechanism of action and molecular targets of Dichroae Radix. Notably, Berberine, the main active ingredient of Dichroae Radix, plays a significant role in degrading AR proteins in advanced prostate cancer. Further studies and validations can provide crucial data to advance cancer metastasis prevention and treatment strategies.

  • Objectives: This study was conducted to clarify the effects of agarwood on histamine release from mast cells in rats and on the scratching behaviors in mice. Methods: Histamine release from rat mast cells induced by compound 48/80 or concanavalin A (Con A) and compound 48/80-induced scratching behavior in mice were examined to investigate the effects of agarwood. The hyaluronidase activity and the 3',5'-cyclic adenosine monophosphate (cAMP) levels in mast cells were examined to investigate the mechanisms for the inhibition of histamine release. The correlation between the inhibitory effects of agarwood on histamine release and the content of its typical ingredients, a 2-(2-phenylethyl)chromone derivatives, was analyzed using thin-layer chromatography. Results: Agarwood showed an inhibitory effect on mast-cell histamine release induced by compound 48/80 or Con A without any effect on hyaluronidase activity; this effect involves an increase in the cAMP levels in mast cells. Oral administration of agarwood showed an inhibitory effect on compound 48/80-induced scratching behavior in mice. The inhibitory effects of agarwood on histamine release were quite different, depending on the area where the agarwood was produced, its quality, and its market price. No correlation was found between the inhibitory effects of agarwood on histamine release and the typical ingredients of agarwood, which are 2-(2-phenylethyl)chromone derivatives. Conclusion: These results show that agarwood inhibits histamine release from mast cells partially through an increase in the cAMP levels in cells. We suggest that some active ingredients of agarwood must be effective on oral intake and that agarwood can be used to treat patients with a number of conditions, including urticaria, atopic dermatitis, and bronchial asthma, in which an increase in histamine release occurs. Differences in the pharmacological effects of this crude drug among markets may provide important information for the quality control of this herbal medicine.

  • Background: Inflammation is a host-defensive innate immune response to protect the body from pathogenic agents and danger signals induced by cellular changes. Although inflammation is a host-defense mechanism, chronic inflammation is considered a major risk factor for the development of a variety of inflammatory autoimmune diseases, such as rheumatic diseases. Rheumatic diseases are systemic inflammatory and degenerative diseases that primarily affect connective tissues and are characterized by severe chronic inflammation and degeneration of connective tissues. Ginseng and its bioactive ingredients, genocides, have been demonstrated to have antiinflammatory activity and pharmacological effects on various rheumatic diseases by inhibiting the expression and production of inflammatory mediators. Methods: Literature in this review was searched in a PubMed site of National Center for Biotechnology Information. Results: The studies reporting the preventive and therapeutic effects of ginseng and ginsenosides on the pathogenesis of rheumatic diseases were discussed and summarized. Conclusion: Ginseng and ginsenosides play an ameliorative role on rheumatic diseases, and this review provides new insights into ginseng and ginsenosides as promising agents to prevent and treat rheumatic diseases.

  • To secure the safety of drugs without compromising drug efficacy, it can not be more important to administer the exact intended amount of active ingredients to patients. Even if the correct amount of drugs are taken in the correct manner, drug can be overdosed or less-dosed without intention unless the content uniformity of the unit dose were secured. Especially, it can be a serious problem when it comes to drugs with narrow therapeutic windows or a strong pharmacological activity at a small dose. (omitted)

  • Ginseng has been used as a traditional herb in Asian countries for thousands of years. It contains a large number of active ingredients including steroidal saponins, protopanaxadiols, and protopanaxatriols, collectively known as ginsenosides. In the last few decades, the antioxidative and anticancer effects of ginseng, in addition to its effects on improving immunity, energy and sexuality, and combating cardiovascular diseases, diabetes mellitus, and neurological diseases, have been studied in both basic and clinical research. Ginseng could be a valuable resource for future drug development; however, further higher quality evidence is required. Moreover, ginseng may have drug interactions although the available evidence suggests it is a relatively safe product. This article reviews the bioactive compounds, global distribution, and therapeutic potential of plants in the genus Panax.

  • The cactus family Cactaceae, numbering about 1,500 species, is a fleshy-stemmed perennial plant which is principally distributed in the south and north America. On the other hand, the cactus plant is presumed to be introduced into Korea in 1912-1945, thereafter it has been cultivated merely in favor of ornamentation with the exception of being occasionally used as medication among laymen. Opuntia elata which belongs to Opuntia genus, the Cactaceae family is one of the cacti being cultivated a great deal in Korea. Cho et. al. reported in 1974 that Opuntia dilenii manifested the cardiac inhibitory effect and oxytocic effect, and its mechanism might be partially due to the direct action. Besides this, there are few reports on the pharmacological research concerning Opuntia genus to be demonstrated in Korea. However, some other cacti have the remarkable pharmacological effects; the active ingredients, mescaline, anhalamine, anhalanine, etc. from Peyote cactus (Lophophora williamsii) belonging to Lophophora genus have the psychotomimetic and sympathomimetic effects, and the cardioactive glycosides from Cactus Grandifolius (Selenicereus grandiflorus) belonging to Cereus genus have the cardioactive and diuretic effects. The authors hereby inquired into this study to find out the propriety of the pharmacological properties of the ethanol extract of Opuntia elata (EX) on the heart, blood pressure, respiration, intestine and uterus in the experimental animals. The results of the experiment were as follows: 1. Administration of EX manifested the cardiac inhibitory effect caused by the negative inotropic action in the isolated heart of frog, and the pretreatment of atropine did not affect the inhibitory effect produced by EX. 2. Administration of EX manifested the transient hypotensive effect in the intact rabbit, and the pretreatment of atropine did not affect the hypotensive effect produced by EX. 3. Administration of the small dose of EX manifested no significant effect, but moderate dose or more the stimulating effect, and the large dose the asphyxia on the respiratory motility in the intact rabbit. 4. Administration of EX manifested the sustained augmentation of contractility in the excised duodenum of rabbit, and the pretreatment of atropine did not affect the stimulating effect produced by EX. 5. Administration of EX manifested the sustained augmentation of contractility in the excised pregnant uterus of rabbit, and the pretreatment of atropine and oxytocin did not affect the oxytocic effect produced by EX, but that of barium chloride more or less stimulated the oxytocic effect produced by EX.
