  • The inhibitory effect of three polyacetylene compounds, panaxydol, panaxynol and panaxytriol isolated from Panax ginseng C.A. Meyer on $CCl_4$induced lipid peroxidation in vivo and in vitro hepatic microsomal lipid peroxidation induced by ADP-$Fe^{3+}$, NADPH and NADPH-cytochrome P-450 reductase were investigated. Their effects on lowering the lipid peroxide levels both in serum and liver and lowering the serum enzyme (GOT, GPT, LDH) activities without the $CCl_4$-induction were also determined. Male ICR mice were pretreated i.p. with polyacetylene compounds or DL-${\alpha}$-tocopherol before administration of $CCl_4$ i.p. and 20 hr after the administration of $CCl_4,$ serum and liver were analyzed. Hepatic microsome was isolated and used for the in vitro NADPH-dependent lipid peroxidation system. Except for panaxynol, treatment with polyacetylenes to control mice did not reduce the levels of lipid peroxides and serum enzyme activities. Panaxynol itself inhibited lipid peroxidation in the liver of normal mice. Polyacetylene compounds protected from the $CCl_4$-induced hepatic lipid peroxidation and lowered serum lipid peroxide levels. Polyacetylenes also inhibited the in virto hepatic microsomal lipid peroxidation in a dose-dependent manner. The results suggest that panaxydol, panaxynol and panaxytriol seem to be the antioxidant components which contribute the anti-aging activities of Panax ginseng C.A. Meyer.

  • 인삼의 항암효과의 분자적 기전을 규명하기 위하여 인삼의 성분 중 강력한 항암효과를 가지는 것으로 보고된 polyacetylene 계 성분이 Ras 단백질의 post-translational modification에 관여하는 효소인 farnesyl protein trasnferase(FPTase)와 carboxyl methyl transferase(CMTase)의 활성에 미치는 영향을 확인하였고, 인삼의 지용성 성분(PEE)이 세포주기에 미치는 영향을 확인하였다. 소의 뇌로부터 FPTase와 CMTase를 부분정제하여 인삼의 polyacetylene계 성분이 두 효소의 활성에 미치는 영향을 확인한 결과, FPTase는 10mM panaxynol과 10mM panaxydol에 의해서 효소활성이 각각 16.2%와 21.3% 저해받았고, CMTase 효소활성은 polyacetylene계 성분인 panaxynol과 pnanxydol에 의해서 활성을 저해받지 않는 것으로 나타났다. 인체 결장 암세포인 HT-29와 인체 간암세포인 HepG2의 배양액에 인삼의 PEE 성분의 첨가배양시 세포크기가 상당히 위축되며 사멸되었음을 볼 수 있었고, 세포주기 분석 결과 인삼의 PEE 성분의 첨가배양시 G1 단계 세포가 증가하고, S단계세포가 감소하여 세포주기의 진행이 G1-S 단계에서 현저히 억제됨을 나타내었다. 이상의 결과로 보아 인삼의 지용성 성분에 의한 항암효과는 Ras의 post-translational modification 에 관여하는 효소의 활성저해에 기인하기보다는 세포주기의 진행 과정에서 세포주기 조절인자들의 발현변화 및 세포주기의 진행에 관여하는 단백질의 활성억제와 관련이 있을 것으로 사료된다.

  • This study investigated the effect that some polyacetylenes and protopanaxatriol, which were isolated from heated ginseng (family Araliaceae), have on inhibiting Helicobacter pylori (HP) growth. Among the compounds tested, panaxytriol was quite effective in inhibiting HP growth with an MIC of 50 ${\mu}g/ml$. Cinsenoside Rhl and protopanaxatriol weakly inhibited $H^{+}/K^{+}$-ATPase from a rat stomach.

  • Several aryl substituted 1,3,5-hexatriynes were synthesized by the use of aryl containing trimethylsilylated 1,3-butadiyne intermediates. 1-Phenyl-1,3,5-heptatriyne, one of the naturally occurring phototoxic conjugated polyacetylenes, and 1-(1'-naphthyl)-1,3,5-heptatriyne were prepared by the use of 1-trimethylsilyl-1,3-pentadiyne which is a very stable precursor for the 1,3-pentadiyne at room temperature.

  • Seven diterpenes, four polyacetylenes, a lipid glycerol, and two sterols were isolated from the methylene chloride fraction of the root of Aralia cordata. Their chemical structures were determined as (-)-pimara-8(14), 15-dien-19-oic acid (2), pimaric acid (3), (-)-kaur-16-en-19-oic acid (4), 17-hydroxy-ent-kaur-15-en-19-oic acid (9), $7{\alpha}$-hydroxy-(-)-pimara-8(14), 15-dien-19-oic acid (10), $16\alpha$, 17 -dihydroxy-(-)-kauran-19-oic acid (11), 16-hydroxy-17-isovaleroyloxy-ent-kauran-19­oic acid (12), falcarindiol (5), dehydrofalcarindiol (6), dehydrofalcarindiol-8-acetate (7), falcarin­diol-8-acetate (8), alpha-mono palmitin (13), stigmasterol (1), and daucosterol (14) by the spectral evidences. These compounds were tested with COX-1 and COX-2 inhibition assays. This study found that compounds 2, 4, 5, 6, 7, 8, and 10 inhibited COX-1 dependent conversion of the exogenous arachidonic acid to $PGE_2$ in a dose-dependent manner with $IC_{50}$ values of $134.2{\mu}M$, $121.6{\mu}M$, $170{\mu}M$, $50.4{\mu}M$, $11.7{\mu}M$, $99.6{\mu}M$, and $69.6{\mu}M$, respectively. But, most of these compounds weakly inhibited COX-2 dependent $PGE_2$ generation. Among them, only compound 4 showed relatively significant inhibitory activity $(IC_{50}\;:\;127.6{\mu}M)$.

  • 정상 wistar rat strain의 체중 및 장기무게 변화 그리고 사료, 물 섭취량의 변화 등을 조사함으로써 polyacetylene 화합물들의 투여량에 따른 독성변수(toxicological parameter)의 범위를 추정하고자 하였다. 또한, ICR mouse strain의 Sarcoma-180으로 유도되는 고형암의 억제와 관련해서 polyacetylene 화합물들의 투여량에 따른 독성변수(toxicological parameter)와의 관계를 관찰하고자 하였다. Panaxydol 40$\mumoles/kg b.w.을 3일간 연속 복강 투여했을때 wistar rat의 체중증가율은 대조군보다 약 17% 감소하였으나, polyacetylene 의 투여를 중지하면 약 4일 경과후부터 체중증가율이 정상으로 회복되었다. 이 투여량을 20$\mumoles/kg b.w.로 줄이면 대조군과의 체중증가율의 차이는 약 10% 정도로 완화되며 그 체중감소율은 panaxydol, panaxynol, panaxytriol의 순으로 증가하였다. 이때 장기무게의 관찰 결과는 대조군과 polyacetylene 화합물들 투여군 사이에 의미있는 차이가 없는 것으로 나타났다. 또한 정상 mice의 간세포에 대한 electron micrograph 관찰결과, panaxydol 40$\mumoles/kg b.w./day 투여시에도 대조군에 비하여 별다른 미세조직의 변화가 관찰되지 않았다.

  • Objectives: Pastinaca sativa (parsnip), is a plant with nutritional and medicinal properties which has been used in all over the world and study about it is rare. In Persian Medicine parsnip is named as zardak and has many uses such as laxative, libido enhancer, kidney stone crusher and diuretic. Because the wide traditional usage of parsnip, in this review the composition and pharmacological properties of this plant are discussed. Methods: Some data base such as Cochrane, Scopus, PubMed were searched up to 2018 for studies about Pastinaca sativa. In this review study after consider to exclusion criteria, all of the English review and clinical trial were included. Results: Finally, 46 articles were selected for extraction data about the parsnip. Data extraction based on these studies the most important active ingredients of parsnip include coumarins, furanocoumarins, polyacetylenes, essential oils and flavonoids. Different studies determined that Pastinaca sativa has pharmacological effects in CNS, respiratory, gastrointestinal, liver, skin, cardiovascular and urogenital diseases. Conclusion: The most important active ingredients in Pastinaca sativa are furanocoumarins, flavonoids and polyacetylenes, and it has many pharmacological properties, including anti-inflammatory, antispasmodic, vasodilator, antifungal, antimicrobial and antidepressant. A main mentioned side effect of parsnip is phototoxicity that was usually reported in direct skin contact. However, family and Some properties and compounds of Pastinaca sativa and Daucus carota are similar but carrots are very popular nowadays. Due to abundant active components and few clinical studies of parsnip, more Studies are recommended to evaluate the effects of it.
