Chelerythrine  (Synonyms: 白屈菜红碱)

目录号: HY-N2359
产品使用指南

Chelerythrine 是一种天然生物碱,为有效、选择性的 Ca2+/磷脂依赖性 PKC 拮抗剂,IC50 值为 0.7 μM。Chelerythrine 具有抗肿瘤、抗糖尿病、抗炎的活性。Chelerythrine 抑制 BclXL-Bak BH3 肽结合,IC50 为 1.5 μM,并从 BclXL 取代了 Bax。 Chelerythrine 诱导细胞凋亡和自噬。

在相同的摩尔浓度下,化合物盐形式与游离形式有相同的生物活性,但盐形式 Chelerythrine chloride 通常具有更好的水溶性和稳定性。

    生物活性

    Chelerythrine is a natural alkaloid, acts as a potent and selective Ca2+/phospholopid-dependent PKC antagonist, with an IC50 of 0.7 μM[1]. Chelerythrine has antitumor, antidiabetic and anti-inflammatory activity[2]. Chelerythrine inhibits the BclXL-Bak BH3 peptide binding with IC50 of 1.5 μM and displaces Bax from BclXL. Chelerythrine triggers apoptosis and autophagy[3][4].

    0.7 μM (IC50)

    体外研究
    (In Vitro)

    Chelerythrine (48 小时) 抑制 L-1210 细胞的生长 (IC50: 0.53 uM)[1]
    Chelerythrine (0-20 μM,24 小时) 可抑制 A549 和 NCI-H1299 细胞的细胞活力,诱导细胞凋亡和自噬[4]
    Chelerythrine (0-5 μM,24 或 48 小时) 可诱导 BclXL 过表达的 SH-SY5Y 细胞凋亡[3]
    Chelerythrine (2.5-10 μM,16 小时) 可诱导 SH-SY5Y 细胞线粒体去极化 (线粒体电位降低),并刺激分离的线粒体释放 CytC[4]
    Chelerythrine (0-100 ng/mL,24 小时) 可减少 LPS 诱导的原代巨噬细胞中 NO 和 TNF-α 的产生[5]
    Chelerythrine (MIC: 0.156 mg/mL) 对革兰氏阳性菌、金黄色葡萄球菌 (SA)、MRSA 和超广谱 β-内酰胺酶金黄色葡萄球菌 (ESBLs-SA) 具有抗菌活性[6]

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
