Tumor angiogenesis is a critical step f3r the growth and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) is the most important angiogenic molecule associated with tumor-induced neovascularization. VEGF exerts its activity through binding to its receptor tyrosine kinase, KDR/Flk-1, expressed on the surface of endothelial cells. This study was carried out to investigate inhibitory effect of extracts from root cortex of Paeonia suffruticosa Andrews on VEGF binding to VEGF receptor. The MeOH extract from P. suffrutiocosa Andr. inhibited the binding of KDR/Flk-1-Fc to immobilized VEGF$_{165}$ more than 45% at the concentration of 100 ${\mu}$g/mL. The MeOH extract was further fractionated into n-hexane, ethyl acetate, n-BuOH, and aqueous fractions. Among the four fractions, the ethyl acetate fraction from the root cortex of P. suffruticosa Andr. exhibited highly effective inhibition (${\approx}$ 79% inhibition) and then n-BuOH fraction (${\approx}$ 45% inhibition) on the binding of KDR/Flk-1-Fc to immobilized VEGF$_{165}$ at the concentration of 100 ${\mu}$g/mL. The ethyl acetate fraction from the root cortex of P. suffruticosa Andr. more efficiently blocked VEGF-induced human umbilical vein endothelial cell proliferation, than the growth of HT1080 human fibrosarcoma. Our results suggest that P. suffruticosa Andr. may be used as a candidate fur developing anti-angiogenic agent.

The bioassay-guided fractionation of protective agents against sepsis-induced lethality from the root cortex of Paeonia suffruticosa ANDREWS (Ranunculaceae) led to the isolation of eight known compounds: paeonol (1), 2,5-dihydroxy-4-methoxyacetophenone (2), acetovanillone (3), paeonoside (4), paeoniflorin (5), oxypaeoniflorin (6), apiopaeonoside (7), and methyl 3-hydroxy-4-methoxybenzoate (8). Among them, 3 showed the highest survival rate (100% with a dose of 30 mg/kg versus 17% for the control experiment) and reduced alanine aminotransferase level to be a half of the control value on the sepsis model induced by lipopolysaccharide/D-galactosamine.

중국에서 재배되는 목단의 품종 중 화형의 연화정도가 다른 대표적인 6개 품종의 뿌리에 대해 채취시기에 따른 paeonol과 paeoniflorin의 함량을 조사하였다. 6개 품종의 뿌리에서 paeonol의 양은 계절에 관계없이 거의 일정하여 변화가 없었다. 반면 paeoniflorin은 개화기인 5월에 가장 높은 값을 보이다가 6월에 감소, 7월에는 증가, 8월에 다시 감소하다가 9월에는 증가하는 경향을 보였다. 비교한 6개의 품종중 화형의 형태가 단순한 종류가 복잡한 종류에 비해 약리성분을 많이 함유하고 있었다. 단판형화관인 Dan Feng과 만첩형 화관의 Wu Long Feng Sheng의 채취시기에 따른 부위별 약리성분의 분포정도를 비교하였다. Paeonol은 두 품종 모두 뿌리를 제외한 잎과 줄기에 미량으로 존재하며 채취시기가 달라져도 변화가 없었다. Paeoniflorin은 뿌리와 잎 두 부분에 다량으로 존재하여 뿌리에서의 분포양이 계절적으로 증감을 반복하는 반면, 잎은 성장이 가장 왕성한 5월에 가장 높게 분포하고 시기가 지날수록 감소하였다.

Objective : Skin aging is commonly observed in patients with diabetes mellitus, which can be accessed by the amount of skin collagen and matrix metalloproteinase-1 (MMP-1). In the present study, anti-skin-aging effects of Root Cortex of Paeonia Suffruticosa Andrews (PSA), which has been widely used to treat diabetes mellitus, are investigated. Methods : Streptozotocin (STZ) was intraperitoneally injected to rats to induce diabetes. Body weights, feed intake, organ weights, blood glucose, and other biochemical index are determined in both normal and diabetic rats. In order to study the effect of PSA on skin aging, the amount of skin collagen was measured in diabetic rats after PSA treatments. Also, MMP-1 synthesis in UVB-irradiated human skin fibroblasts was investigated. Results : 1. When PSA was administered to STZ-induced diabetic rats, feed intake was significantly increased and blood glucose and total cholesterol were decreased in a dose-dependent manner. However, there are no differences in individual organ weights, GOT, and GPT. 2. A decrease of skin collagen in diabetic rats was significantly suppressed when PSA was treated. 3. PSA also inhibited MMP-1 synthesis in UVB-irradiated normal human skin fibroblasts, similar to retinoid, a well-known effective anti-skin-aging substance. Conclusion: PSA suppressed a collagen decrease in diabetic rats and inhibited MMP-1 synthesis in UVB-irradiated human skin fibroblasts. Therefore, the treatment of PSA is very effective to slow down the skin aging process.

Paeonol is a major component found in the Paeoniaceae family such as Paeonia suffruticosa Andrews. Paeonia suffruticosa Andrews has traditionally been used to enhance blood flow and relieve joint pain in east Asian countries including China, Korea and Japan. Current research has shown that paeonol blocked the voltage-gated sodium channel and L-type calcium channel. However, there is a lack of research to reveal the relation between cardiac function and blockade of ion channels by paeonol. Therefore, the aim of this study is to investigate whether paeonol has anti-arrhythmic effects via modulating cardiac ion channels. It is collected that the effects of paeonol on multiple ion channels such as the fast sodium channel and L-type calcium channel from published papers. To incorporate the information on multi-channel block, we computed the effects using the mathematical cardiac model of the guinea-pig and rat ventricular cells (Noble 1998 and 1991 model) and induced early after-depolarizations (EADs) to generate an arrhythmia in the whole heart. Paeonol slightly shortened the action potential duration in the normal cardiac ventricular action potential by the inhibition of sodium channel and L-type calcium channel. Paeonol presented the protective effect from EADs by the inactivation of sodium channel but not L-type calcium channel. Paeonol did not show any changes when it treated on normal ventricular cells through the inhibition of sodium channel, but the protective effect of paeonol through sodium channel on EADs was dose-dependent. These findings suggest that paeonol and its original plant may possess anti-arrhythmic activity, which implies their cardioprotective effects.

본 연구는 항주름 소재를 개발하기 위해서 목단피로부터 gallic acid (GA)를 분리하여 항산화능을 측정하였고, HaCaT 세포에서 세포독성을 측정하였다. 또한 HaCaT 세포에서 tumor necrosis factor alpha (TNF-${\alpha}$)에 의해 유도되는 matrix metalloproteinase-1 (MMP-1) mRNA 발현, protein 발현, 분비에 대한 GA의 영향을 관찰하였다. 결과로써 GA는 30 ${\mu}g/mL$의 $IC_{50}$과 함께 항산화능을 나타내었고, 그것의 항산화능은 합성항산화제인 butylated hydroxyanisol (BHA)보다 높았다. GA는 HaCaT 세포에서 고농도인 200 ${\mu}g/mL$ 처리시 약한 세포독성을 나타내었다. 또한 HaCaT세포에서 TNF-${\alpha}$ (10 ng/mL)의 처리에 의해 증가된 MMP-1의 mRNA 발현, protein 발현, 분비는 GA의 처리에 의해 농도 의존적으로 유의적인 감소를 나타내었다(p<0.05). 그러므로 GA는 항산화 효과와 TNF-${\alpha}$로부터 유도되는 MMP-1의 발현을 저해함으로써 피부 주름을 개선할 수 있는 주름개선제로서의 활용가능성을 확인하였다.

The application of PCR analysis on the herbal medicine Moutan Cortex (Paeonia suffruticosa Andrews) was evaluated by the comparison of the genetic relationship based on the DNA sequence with Paeoniae Radix (Paeonia lactiflora Pallas) following development of specific primers. Moutan Cortex and Paeoniae Radix were distinguished through the PCR analysis based on the internal transcribed spacer (ITS-PCR) from nuclear ribosomal DNA region. The 294 bp PCR products both of Moutan Cortex and Paeoniae Radix was amplified by MIF1 and MIR1. And a Moutan Cortex specific 225 bp PCR amplification product was amplified by MIF2 and MIR1 primers. The 225 bp sequence could be successfully amplified from Mortan Cortex of dried herbal preparations. PCR analysis based on ITS (ITS-PCR) may be an efficient tool for the discrimination of Moutan Cortex.

Root barks of Paeonia suffruticosa Andrews (PS) was reported as contraindicated drugs of pregnancy by many Korean medical classics. Recently, a major ingredient component of PS, paeonol was reported that has contraceptive effect on early pregnancy in rats. However, the accurate molecular mechanism is not clear. In this study, we showed that PS decreased the expression of receptor for leukemia inhibitory factor (LIFR) in human endometrial Ishikawa cells at non-toxic dose, although the expression of leukemia inhibitory factor (LIF) was increased by PS. In addition, PS inhibited the adhesion of human trophoblastic JAR cells onto Ishikawa cells. Given importance of LIF-LIFR signaling pathway in the process of embryo implantation, the decreased LIFR expression by PS will be a good explanation on the PS- or its ingredient compounds-induced contraception.
