Peiminine

Peiminine is an alkaloid extracted from the bulb of Fritillaria thunbergii Miq that reportedly has anticancer and anti-inflammatory effects. Peiminine downregulated the levels of specific genes and proteins in vitro and consequently suppressed OC (Osteoclasts) differentiation and function². Peiminine inhibits lung inflammation and pulmonary fibrosis in a rat model of bleomycin-induced lung injury, by reducing circulating IFN-γ levels and inhibiting signal transduction pathways involving TGF-β, CTGF, ERK1/2, NF-κB and FasL³. Peiminine induced G0/G1-phase arrest, apoptosis, and autophagy in human osteosarcoma cells via the ROS/JNK signaling pathway both in vitro and in vivo⁴. Peiminine (1, 3, or 5 mg/kg) could reduce the W/D ratio and the MPO activity significantly. Furthermore, the histopathological changes and the expression of TNF-α, IL-1β, and IL-6 were inhibited after the peiminine treatment. In vitro, peiminine significantly inhibited LPS-induced IL-8 production in A549 lung epithelial cells⁵. Peiminine suppressed the development of CRC through inhibiting the viability, colony formation and metastasis of CRC (Colorectal cancer) cells via LINC00659/miR-760 axis⁶.

溶解方案(动物实验)

"方案 一": "请依序添加每种溶剂：10% DMSO 40% PEG300 5% Tween-80 45% SalineSolubility: ≥ 2.5 mg/mL (5.82 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。"

"方案 二": "请依序添加每种溶剂：10% DMSO 90% (20% SBE-β-CD in Saline)Solubility: ≥ 2.5 mg/mL (5.82 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。"

"方案 三": "请依序添加每种溶剂：10% DMSO 90% Corn OilSolubility: ≥ 2.5 mg/mL (5.82 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液，此方案实验周期在半个月以上的动物实验酌情使用。以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。"
