국내산 왕지네(Scolopendra subspinipes mutilans)의 식 약용으로써의 이용 가능성을 알아보고자 경남 산청, 전남 영광, 제주도 지역 왕지네의 영양성분 및 유해물질을 비교분석한 결과, 일반성분 중 조단백질은 3개 지역에서 54.9-55.8%로 전체적으로 매우 높은 함량을 나타냈고 조지방은 26.8-30.6%였다. 필수아미노산에서는 라이신이 3.4-3.6%로 가장 많았다. 집중력과 기억력 증진 및 인지능력 개선에 도움이 되는 glutamic acid는 비필수아미노산 중 가장 많은 함량인 6.8-7.1%로 지역 간에 비슷하였다. 불포화지방산에서는 심장질환 및 암 예방에 효과가 있는 oleic acid가 지역 간에 41.3-46.8%로 가장 높은 함량을 보였다. 유해물질 분석 결과, 3개 지역에서 중금속인 수은이 0.08-0.11 mg/kg 검출되었으나, 일반식품 허용 기준치 이하로 확인되었다. E. coli와 Salmonella spp.와 같은 병원성 미생물은 검출되지 않았다. 지역별로 국내산 왕지네의 영양성분 및 유해물질 비교분석 결과, 지역 간에 뚜렷한 차이는 없었다. 왕지네는 단백질, 필수아미노산, 불포화지방산 및 체내에서 합성하지 못하는 많은 영양소들을 함유하고 있기 때문에 식 약용으로 활용될 가치를 충분히 가지고 있다고 판단되었다.

Objective : The purpose of this study is to investigate nucleotide sequence and extract cytotoxicity of Scolopendrae corpus. The nature and taste of Scolopendrae corpus is hot, Warm and toxic, and the effect of this is dispelling wind, anti-spasmodic action and detoxication so it has been used for C.V.A, facial palsy, sensory disorder at extremities, wounds and arthritis. Methods : Scolopendrae corpus were collected by locality on the market. They were morphologically classified. Their nucleotide sequence was investigated and compared among them. In addition, the water-alcohol extract cytotoxicity of them was studied by MTT-based cytotoxicity assay. Results : It was shown that the each Scolopendrae corpus by locality is almost identical at genetic result and is identified as Scolopendra subspinipes mutilans L. Koch. Nucleotide sequence of Scolopendra subspinipes mutilans L. Koch in this study will help to discriminate other species of Scolopendrae corpus. The water-alcohol extract of Scolopendra subspinipes mutilans L. Koch did not induce cytotoxicity on Hep G2, L929 cell and peritoneal macrophages. Besides, it did not influence nitrite production of peritoneal macrophages. These results can be used as basic data for genetic discrimination with another species of scolopendrae corpus.

지네 Scolopendra subspinipes multilans L. Koch로부터 정제한 Centipedin의 gram-negative, gram-positive bacteria 및 fungi에 대한 광범위 항균 spectrum을 조사하였으며 액체배지를 사용하여 각 균주에 대한 minimal inhibitory concentrations(MICs)값을 측정하였다. 인체의 기관중 주로 폐에 감염되는 gram-negative bacteria인 Klebsiella pneumoniae ATCC 8308 균주에 대한 MIC값이 $2{\mu}g/ml$로서 가장 강한 항균력을 나타내었고 화농균인 Proteus vulgaris NRRL B-123 균주에 대해서도 MIC값이 $16{\mu}g/ml$로 비교적 높은 항균력을 나타내었으며 항균제로서의 작용 mechanism을 시험한 결과 prokaryotic RNA transcription을 억제함을 알 수 있었다. Human blood leukemia(HL-60)와 mouse B lymphocyte myeloma cell 등의 동물세포에 대한 Centipedin의 cytotoxicity는 없는 것으로 확인되었다.

In a previous report, we identified several candidate antimicrobial peptides through de novo RNA sequencing of the centipede Scolopendra subspinipes mutilans. Here, we identify and characterize one of these peptides, Scolopendrasin I. We identified the centipede antimicrobial peptide Cecropin from the centipede transcriptome using an SVM algorithm, and subsequently analyzed the amino acid sequence for predicted secondary structure using a GOR algorithm. We identified an alpha helical region of Cecropin and named it Scolopendrasin I. We then assessed antimicrobial and hemolytic activity of Scolopendrasin I. Scolopendrasin I showed antimicrobial activity against various microbes, including antibiotic-resistant Gram-negative bacteria, in a radial diffusion assay. Scolopendrasin I had potent antibacterial activity against acne-associated microbes in a colony count assay and showed no hemolytic activity in a hemolysis assay. In addition, we confirmed that Scolopendrasin I bound to the surface of bacteria via a specific interaction with lipoteichoic acid and lipopolysaccharide, two components of bacterial cell membranes. In conclusion, the results presented here provide evidence that this is an efficient strategy for antimicrobial peptide candidate identification and that Scolopendrasin I has potential for successful antibiotic development.

The centipede Scolopendra subpinipes mutilans is a medicinally important arthropod species. However, its transcriptome is not currently available and transcriptome analysis would be useful in providing insight into a molecular level approach. Hence, we performed de novo RNA sequencing of S. subpinipes mutilans using next-generation sequencing. We generated a novel peptide (scolopendrasin II) based on a SVM algorithm, and biochemically evaluated the in vitro antimicrobial activity of scolopendrasin II against various microbes. Scolopendrasin II showed antibacterial activities against gram-positive and -negative bacterial strains, including the yeast Candida albicans and antibiotic-resistant gram-negative bacteria, as determined by a radial diffusion assay and colony count assay without hemolytic activity. In addition, we confirmed that scolopendrasin II bound to the surface of bacteria through a specific interaction with lipoteichoic acid and a lipopolysaccharide, which was one of the bacterial cell-wall components. In conclusion, our results suggest that scolopendrasin II may be useful for developing peptide antibiotics.

We investigated the effects of two antimicrobial peptides (AMPs) isolated from Scolopendra subspinipes mutilans on neutrophil activity. Stimulation of mouse neutrophils with the two AMPs elicited chemotactic migration of the cells in a pertussis toxin-sensitive manner. The two AMPs also stimulated activation of ERK and Akt, which contribute to chemotactic migration of neutrophils. We found that AMP-stimulated neutrophil chemotaxis was blocked by a formyl peptide receptor (FPR) 1 antagonist (cyclosporin H); moreover the two AMPs stimulated the chemotactic migration of FPR1-expressing RBL-2H3 cells but not of vector-expressing RBL-2H3 cells. We also found that the two AMPs stimulate neutrophil migration in vivo, and that this effect is blocked in FPR1-deficient mice. Taken together, our results suggest that the two AMPs stimulate neutrophils, leading to chemotactic migration through FPR1, and the two AMPs will be useful for the study of FPR1 signaling and neutrophil activation.

Objectives: Scolopendra subspinipes mutilans (S. subspinipes mutilans) is known as a traditional medicine and includes various amino acids, peptides and proteins. The amino acids in the pharmacopuncture extracted from S. subspinipes mutilans by using derivatization methods were analyzed quantitatively and qualitatively by using high performance liquid chromatography (HPLC) over a 12 month period to confirm its stability. Methods: Amino acids of pharmacopuncture extracted from S. subspinipes mutilans were derived by using O-phthaldialdehyde (OPA) & 9-fluorenyl methoxy carbonyl chloride (FMOC) reagent and were analyzed using HPLC. The amino acids were detected by using a diode array detector (DAD) and a fluorescence detector (FLD) to compare a mixed amino acid standard (STD) to the pharmacopuncture from centipedes. The stability tests on the pharmacopuncture from centipedes were done using HPLC for three conditions: a room temperature test chamber, an acceleration test chamber, and a cold test chamber. Results: The pharmacopuncture from centipedes was prepared by using the method of the Korean Pharmacopuncture Institute (KPI) and through quantitative analyses was shown to contain 9 amino acids of the 16 amino acids in the mixed amino acid STD. The amounts of the amino acids in the pharmacopuncture from centipedes were 34.37 ppm of aspartate, 123.72 ppm of arginine, 170.63 ppm of alanine, 59.55 ppm of leucine and 57 ppm of lysine. The relative standard deviation (RSD %) results for the pharmacopuncture from centipedes had a maximum value of 14.95% and minimum value of 1.795% on the room temperature test chamber, the acceleration test chamber and the cold test chamber stability tests. Conclusion: Stability tests on and quantitative and qualitative analyses of the amino acids in the pharmacopuncture extracted from centipedes by using derivatization methods were performed by using HPLC. Through research, we hope to determine the relationship between time and the concentrations of the amino acids in the pharmacopuncture extracted from centipedes.
