Objectives : This study aimed to predict the effectiveness and potential of Schizonepeta tenuifolia as an anticancer treatment for non-small cell lung cancer through network-based pharmacology and cellular experiment. Methods : To identify the major bioactive compounds in Schizonepeta tenuifolia, we used the Traditional Chinese Medicine Systems. The target genes for the cancer treatment were selected using the UniProt database and the networked using Cytoscape. We performed functional enrichment analysis based on the Gene Ontology Biological Process and Kyoto Encyclopedia of Genes and Genomes Pathways to predict the mechanisms. To investigate the effect of Schizonepeta tenuifolia on lung cancer cell growth, we treated A549 cells, a lung cancer cell line, with different concentrations of the drug and used the MTT assay for cell viability. Results : Research has shown that the most effective mechanism of active compounds from Schizonepeta tenuifolia is through the pathway of cancer. The results of the network pharmacology analysis indicate that Schizonepeta tenuifolia has potential medicinal value as an adjuvant in anticancer treatment. The concentration-dependent inhibition of cell viability was observed on A549 cells. Furthermore, synergistic anticancer activity with Doxorubicin was also observed. Conclusions : Through a network pharmacological approach, Schizonepeta tenuifolia was predicted to have potential as an anticancer agent, and its efficacy was experimentally demonstrated using A549 cells. These findings suggest that Schizonepeta tenuifolia is a promising candidate for future research.

The callus was induced from the seedlings of Schizonepeta tenuifolia Brig. (Labiatae) and the effects of culturing conditions on growth rate and essential oil formation of the callus were experimented. It was found in the experiments, that the proper culturing temperature is $23^{\circ}C$ and the addition of biosynthetic precursors(leucine, mevalonic acid lactone) inhibits the growth of the callus. The growth rate of the callus and the amount of essential oils of the callus in the medium containing NAA were higher than the medium containing 2,4-D. The essential oils from the callus and the leaves of the cultivated Schizonepeta tenuifolia showed different GC pattern, but pulegone was found in both oils.

Schizonepeta spike (Korean name "Hyung-Gae") has been used for oriental medicinal purposes in Korea, China and Japan. In this study, twenty six "Hyung-Gae" samples were collected including nine certified Schizonepeta tenuifolia plants, and seventeen commercially marketed "Hyung-Gae" products. Chloroplast trnL-F and rDNA ITS regions of the "Hyung-Gae" samples were sequenced and used to identify whether the samples were genuine S. tenuifolia or not. As the result, the trnL-F and ITS sequences of all the "Hyung-Gae" samples were shown to be identical and it was proven that commercially available medicinal products "Hyung-Gae" are genuine S. tenuifolia. Phylogenetic tree of S. tenuifolia using the trnL-F sequences was constructed and compared with phylogenetic tree using ITS of rDNA region sequences. In these tree, S. tenuifolia was affiliated in the family Lamiaceae. It is proven that trnL-F and ITS phylogenetic trees are useful to study taxonomic position of S. tenuifolia.

Schizonepeta tenuifolia (Korean name "Hyung- Gae") is an oriental medicinal plant that is widely used in Korea, China and Japan. S. tenuifolia (Hyung-Gae) has many pharmacological activities and is mostly used for many medicinal preparations. The dried aerial part (spikes and stems) of three oriental medicinal plants, S. tenuifolia (Hyung-Gae), Agastache rugosa (Kwhak-Hyang) and Elsholtzia ciliata (Hyang-Yoo) belonging to the same family, mint family Labiaceae, have such similar shape and smell that it is difficult to differentiate between them. The trnL-F regions of chloroplast DNA of the three medicinal plants were sequenced and used as targets in multiplex PCR reaction to identify S. tenuifolia. After alignment of trnL-F sequences of the authenticated plant samples, one single nucleotide polymorphism (SNP) specific to S. tenuifolia was found. Based on this SNP, a new primer was designed that specifically amplifies the trnL-F region of S. tenuifolia. The established multiplex-PCR was proven to be effective in the differentiation of commercial S. tenuifolia samples from A. rugosa and E. ciliata. This rapid and accurate molecular method is highly promising for use in the food industry.

Immediate-type hypersensitivity is involved in many allergic diseases such as asthma, allergic rhinitis and anaphylaxis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. Stimulation of mast cells releases inflammatory mediators, such as histamine and pro-inflammatory cytokines with immune regulatory properties. We investigated the effect of the aqueous extract of Schizonepeta tenuifolia (AEST) (Labiatae) on the immediate-type allergic reaction. AEST inhibited compound 48/80-induced systemic allergic reaction. AEST attenuated immunoglobulin E (IgE)-mediated skin allergic reaction and histamine release from human mast cell line (HMC-1) cells. In addition, AEST decreased the gene expression and secretion of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated HMC-1 cells. Our results indicate that AEST inhibits the mast cell-derived allergic reactions and involvement of histamine and pro-inflammatory cytokines in these effects.

The Schizonepeta tenuifolia spikes (STS) have been used as a traditional folk medicine for antiinflammatory, analgesic, anti-pyretic and anti-spasmodic purpose in Korea. Phytosterols (mixture of campesterol 3.68%, stigmasterol 2.30% and ${\beta}$-sitosterol 94.02%) and hesperidin were isolated by chromatography from ether and n-BuOH fractions of STS respectively. These compounds significantly reduced the blood glucose level and lessened the loss of body weight and water consumption dose-dependently when administered at a i.p. doses of 10 and 20 mg/kg for 4 days after the i.v. injection of streptozotocin (I 80 mg/kg). In the morphologic study, these compounds showed protective activity on the pancreatic islets, especially .betha.-cells, from the degenerative changes by streptozotocin.

This study evaluates the radiation protection effects of Schizonepeta tenuifolia water extract on white rat by gender. Schizonepeta tenuifolia contains polyphenol and flavonoid, which are typical substances that remove free radical. Thus, to determine the effectiveness of radiation protection, the Schizonepeta tenuifolia water extract was administered to Sparaqu-Dawely (SD) rat males and females for two weeks, followed by hematological analysis, analysis of changes in the length of the small intestine villi length, and SOD activity evaluation. The male rat in ST+IR group showed a slightly greater recovery of platelets than the IR group. The ST+IR group also showed a higher platelet recovery capability than the IR group. lymphocyte showed that male and female rat ST+IR groups have higher resilience than IR groups likewise platelet. After irradiation, the villi length of the male rat and female rat decreased less in ST+IR group than in the IR group, indicating that the villi length of all genders was less damaged. This result confirmed that the Schizonepeta tenuifolia water extract had a radiation protection effect.
