Rosmanol could inhibit the oxidation of low density lipoprotein (LPL) and significantly inhibit lipopolysaccharide induced iNOS and COX-2 expression, with anti-inflammatory effect.

Rosmanol exhibits the strongest inhibition on cell viability with IC₅₀ approximately 42 μM. Rosmanol might suppress cancer cell proliferation or induce cancer cell undergoing apoptosis that lead to cell growth-inhibition. With 50 μM of Rosmanol treatment, the percentage of COLO 205 cells undergoing apoptosis increase dramatically from 9 h (29%) to 24 h (51%). Within 24 h of treatment with 50 μM Rosmanol, COLO 205 cells exhibit significant morphological changes and chromosomal condensation, which is indicative of apoptotic cell death^[1]. Carnosol is a lipid protector against attack by O₂^[2].

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用； 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

• 1.

  请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% saline

  Solubility: ≥ 7.5 mg/mL (21.65 mM); Clear solution

  此方案可获得 ≥ 7.5 mg/mL (21.65 mM，饱和度未知) 的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 75.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液
