60종의 생약의 methanol 추출물을 L1210세포에 대하여 1차스크리닝실험을 수행하여 항암활성물질을 검색하고, 그 중에서 비교적 세포독성이 강하게 나타나는 산국(Chrysanthemum boreale M.)에서 항암활성물질을 분리정제하였다. 산국의 용매분획물의 L1210, K562, A549세포에 대한 세포독성실험에서는 chloroform 분획에서 $ED_{50}$값이 각각 3.98, 4.28, 3.84 (${\mu}g/ml$)로 나타났다. 이 chloroform 분획에서 유효세포독성물질을 정제하여 Compound I과 Compound II를 각각 얻었으며, 이 중에서 Compound I은 L1210, K562, A549세포에 대하여 각각 $ED_{50}$값이 0.55, 0.0003, 0.001 (${\mu}g/ml$)로 강한 세포독성을 나타내었으나, Compound II는 K562에 대해서만 $ED_{50}$ 값이 4.79 (${\mu}g/ml$)의 세포독성을 나타내었다.

본 연구는 개똥쑥(Artemisia annua L., AA), 유자(Citrus junos Sieb. ex TANAKA, CJ), 산국화(Chrysanthemum boreale Makino, CB), 잣나무(Pinus koraiensis, PK), 금강송(Pinus densiflora for. erecta, PD) 총 5 종의 자생식물 essential oil의 항 아토피 효능을 확인하기 위한 실험이다. 항균 효과를 확인하기 위해 자생식물 essential oil 5 종을 Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans 총 4 종류의 균에 처리했다. 항염증 효과를 확인하기 위해 TNF-α와 IFN-γ (TI)를 처리한 HaCaT 세포에 5 종의 자생식물 essential oil을 처리했다. AA, CJ, CB, PK, PD은 10 mg/mL 농도에서 Candida albicans에 대한 항균 효과를 나타냈다. AA (1 ㎍/mL), CB (1 ㎍/mL), PK (0.1, 1 ㎍/mL)에서 thymus and activation-regulated chemokine (TARC) 생성량이 억제되었고, AA 및 PK (1 ㎍/mL)에서 macrophage-derived chemokine (MDC) 생성량이 억제되었으며, AA (0.1, 1 ㎍/mL), PK (0.1, 1 ㎍/mL)에서 IL-6 생성량이 억제되었다. AA, CB, PK essential oil의 항균 및 항염증 효과가 확인되었으며, 이에 아토피 피부염 완화에 기여할 수 있음을 기대한다.

Nine sesquiterpene lactones, which were isolated from Hemisteptia lyrata Bunge, Chrysanthemum zawadskii Herbich var. latilobum Kitamura and Chrysanthemum boreale Makino were evaluated for the inhibition upon the nitric oxide release from the Raw cell and for the ACAT (acyl Co A: cholesterol acyltransferase) inhibitory assay. In the nitric oxide release inhibitory experiment, hemistepsin B $(IC_{50}\;=\;0.05\;{\mu}g/ml,\;0.15\;{\mu}M),$ cumambrin B, tulipinolide and costunolide exhibited strong inhibition with $IC_{50}$ values $0.05\;{\mu}g/ml\;(0.15\;{\mu}M),\;0.1\;{\mu}g/ml\;(0.38\;{\mu}M),\;0.2\;{\mu}g/ml\;(0.69\;{\mu}M)$ and $0.2\;{\mu}g/ml(0.86\;{\mu}M),$ respectively. In the ACAT inhibitory assay, angeloylcumambrin B, tigloylcumambrin B, tulipinolide and costunolide exhibited strong inhibition with $IC_{50}$ values $33\;{\mu}g/ml\;(95.4\;{\mu}M),\;22\;{\mu}g/ml\;(63.6\;{\mu}M),\;38\;{\mu}g/ml\;(151\;{\mu}M)$ and $17\;{\mu}g/ml(73.3\;{\mu}M),$ respectively, whereas other compounds did not exhibit significant activity against ACAT above $100\; {\mu}g/ml.$.

We have isolated a sesquiterpene lactone, cumambrin A from the dried flowers of Chrysanthemum boreale Makino and reported its chemical structure. The aim of the present study was to investigate whether the exogenous administration of cumambrin A has a pharmacological effect on normalization of blood pressure in the spontaneously hypertensive rats (SHR). In vitro studies: Relaxative response induced by cumainbrin A was increased with dose-dependent manner and showed maximizing response at a concentration of $5{\times}10^{-4}M$. Further, this relaxative response was significantly increased at a condition of endothelium present than that of endothelium denuded. In vivo studies: The normalizing effect of cumambrin A on blood pressure was also increased with time-dependent manner and then gradually recovered to normal condition at approximately 4 hrs after cumambrin A treatment.

We previously reported that the exogenous administration of cumambrin A, a sesquiterpene lactone from the dried flowers of Chrysanthemum boreale Makino has a pharmacological effect on normalization of blood pressure in the spontaneously hypertensive rats (SHR). In the present study, we further investigated the effect of cumambrin A on the relaxation of phenylephrine-induced precontracted rat aortic artery rings. The potency of cumambrin A was than compared to verapamil, a well known $Ca^{2+}-channel$ blocker. The results demonstrate that the isolated rat aortic arteries are relaxed to basal tension at a concentration of $5{\times}10^{-5}\;M$ cumambrin A treatment. The results also show that the phenylephrine-induced contraction is inhibited by a pretreatment of cumambrin A. Co-treatment of cumambrin A and verapamil showed a strong synergetic effect on the relaxation of rat aortic artery rings. Thus, these data demonstrate that cumambrin A is a potent relaxant of rat aortic smooth muscle and suggest that cumambrin A modulates intracellular or extracellular $Ca^{2+}$ mobilization.

To search for novel cancer preventive agents, we assessed the quinone reductase (QR)-inducing activities of medicinal herb extracts in cultured murine hepatoma cells (hepalclc7 cells). Among 216 herb extracts tested in this study, 8 kinds of herbal extracts were found to induce QR activity in hepalclc7 cells by more than 2-fold when used at the concentration of 25 $\mu\textrm{g}$/$m\ell$. The methanol extracts of Aster koraiensis NK and Pulsatilla koreana Nakai induced QR by 252 and 223 % , respectively, at the concentration of 25 $\mu\textrm{g}$/$m\ell$. Most of the herbal extracts with QR inducing-activity increased the enzyme activity in a typical dose-dependent manner. The QR activity in BP$^{r}$ cl cells was induced move than 50 % by the extracts of Pulsatilla koreana Nakai, Inula helenium, Physalis alkekengi var, francheti (Masters) Makino, Chrysanthemum zawadskii var. latilobum Kitamuva, Auemisia keiskeana Miquel, Chfsanthemum boreale Makino. In conclusion, hlsatilla koreana Nakai, Aster koraiensis N.K, and Chfsanthemum zawadskii var. iatilobum Kitamura, which showed relatively high QR induction, merit further animal study to evaluate their potential as cancer preventive agents.
