    Isolation and Structure Elucidation of an Isoflavone and a Sesterterpenoic Acid from Henriettella fascicularis
    摘要:
    A new isoflavone, 4',5,7-trihydroxy-6,8-dimethylisoflavone (1), and a new sesterterpenoic acid (2), together with five known compounds, lichexanthone (3), (-)-pinoresinol (4), betulinic acid, palmitic acid, and beta-sitosterol, were isolated from a dichloromethane extract of the branches of Henriettella fascicularis. Their structures were established by extensive spectroscopic methods. An attempt to determine the absolute stereochemistry of (2E,6S)-6-[(1R,5Z,3aS,9R,10Z,12aR)-1,2,3,3a,4,7,8,9,12,12a-decahydro-9-hydroxy-3a,6,10-trimethylcyclopentanocycloundecen-1-yl]-2-methylhept-2-enoic acid (2) was performed by single-crystal X-ray analysis, using Cu Kalpha radiation. Compound 1 showed significant competitive binding to estrogen receptor beta and moderate antiestrogenic activity with cultured Ishikawa cells.

    본 발명자들은 생물학적 활성을 지닌 천연 화합물인 C-메틸이소플라본 화합물 이소시더록실린 (화합물 1), 6,8-다이메틸제니스테인 (화합물 2) 및 그 유도체들 (화합물 3~8)을 상업적으로 입수 가능한 전구체로부터 전체 수율 16~24%로 7~8 단계로 간단하고 효율적으로 합성하였다. 이 전략에서 빌스마이어-해크 반응 (Vilsmeier-Haack reaction), 프리델-크라프츠 아실화 (Friedel-Crafts acylation)와 탈메틸화 동시반응, 개밀의 프로토콜 (Gammill's protocol) 및 스즈키 커플링 반응 (Suzuki coupling reactions)이 주요 단계로 적용되었다. 또한, 본 발명에서는 화합물 1~8에 대하여 LPS로 유도된 RAW264.7 대식세포에서 NO 생성을 억제하는 능력을 분석하였다. 시험한 모든 시료들은 농도 의존적으로 NO 생성을 감소시켰고 고농도 (10 μmol/L)에서 명확한 세포독성을 나타내지 않았으며, 10.17 내지 33.88 μmol/L 범위의 IC값으로 효율적인 저해 효과를 나타냈다. 중요한 점은 화합물 3 (IC= 10.17 μmol/L), 화합물 1(IC= 13.2 μmol/L), 화합물 7(IC= 13.21 μmol/L)과 화합물 8 (IC= 14.67 μmol/L)이 양성 대조군으로 이용되는 L-NMMA (N-monomethyl-L-arginine) (IC = 7.82 μmol/L)와 비교하여 상당한 억제효과를 나타냈다.
    这段文本是关于一项合成具有生物活性的天然化合物的研究成果的描述。研究者们成功地从商业上可获得的前体中,简单而高效地合成了具有生物活性的C-甲基异黄酮化合物异硫代磷酸酯林(化合物1)、6,8-二甲基黄酮(化合物2)及其衍生物(化合物3~8),总收率为16~24%,经过7~8个步骤。在这一合成策略中,应用了维尔斯迈尔-哈克反应(Vilsmeier-Haack reaction)、弗里德尔-克拉夫斯酰化(Friedel-Crafts acylation)和去甲基化的同时反应,甘米尔的协议(Gammill's protocol)以及铃木偶联反应(Suzuki coupling reactions)作为主要步骤。此外,研究还分析了化合物1~8在LPS诱导的RAW264.7巨噬细胞中抑制NO生成的能力。所有测试样品均呈浓度依赖性地降低了NO生成,并且在高浓度(10 μmol/L)下没有明显的细胞毒性,而在10.17至33.88 μmol/L范围内显示出有效的抑制作用。重要的是,化合物3(IC=10.17 μmol/L)、化合物1(IC=13.2 μmol/L)、化合物7(IC=13.21 μmol/L)和化合物8(IC=14.67 μmol/L)相对于阳性对照组L-NMMA(N-单甲基-L-精氨酸)(IC=7.82 μmol/L)表现出显著的抑制效果。

    We have discovered that p63 inhibition results in increased cellular proliferation. We have also performed a screen for agents capable of increasing cellular proliferation, (e.g., of stem cells such as skin-derived precursors (SKPs)). The invention therefore invention provides compositions, methods, and kits for increasing proliferation of cells, using compounds that decrease p63 expression or activity or using the compounds described herein. The invention also features methods of using these compounds for increasing hair growth, improving skin health, or promoting skin repair in a subject.

Next, these compounds evaluated for their inhibitory potency on the production of nitric oxide (NO) in lipopolysaccharide (LPS)-activated RAW-264.7 cells as an indicator of anti-inflammatory activity. The results showed that all the compounds decreased NO production in a dose-dependent manner without marked cytotoxicity and IC 50 values are found
