體外研究
(In Vitro)

Tetrahydrocurcumin (THC) 具有許多姜黃素所不具備的吸引人的特性,這些特性可能使其更勝一籌。Tetrahydrocurcumin (THC)可抑制低至 1 μM 的脂氧合酶。測試了Tetrahydrocurcumin 抑制 CYP2C9、CYP3A4、CYP1A2 和 CYP2D6 的能力。Tetrahydrocurcumin 對 CYP2C9 產(chǎn)生劑量依賴性抑制,對 CYP3A4 的抑制作用較小。Tetrahydrocurcumin 在 50 至 100 μM 時表現(xiàn)出對 CYP2C9CYP3A4 的最大抑制作用。在測試的濃度范圍內(nèi),Tetrahydrocurcumin 未顯示出對 CYP1A2CYP2D6 的一致劑量反應(yīng)抑制。在某些情況下,抑制百分比超過 100%。測量了四氫姜黃素對癌細(xì)胞活力的影響。Sup-T1 細(xì)胞,T 細(xì)胞淋巴母細(xì)胞淋巴瘤細(xì)胞,用 Tetrahydrocurcumin 處理,使用 MTS 測定法確定其誘導(dǎo)生長抑制的能力,相應(yīng)的 IC50 值處于中高微摩爾范圍[1]。

(In Vivo)

Tetrahydrocurcumin (THC) 濃度與時間的曲線表明存在不止一個吸收和分布階段。最初,觀察到一個快速吸收階段,1 小時的平均 Tmax 為 6.8 μg/mL,然后是一個短暫的消除階段。隨后在 6 小時和 24 小時進(jìn)行兩次重新分配,其中兩個較小的四氫姜黃素最大值。兩個再分布階段具有相似的最大值,約為 1 μg/mL。24 h 尿液中未變化的四氫姜黃素總量可達(dá) 8 μg[1]

Cell Assay
[1]

Sup-T1 cells are cultured in RPMI 1640 supplemented with 10% FBS and 1% Penicillin/Streptomycin at 37°C and 5% CO22. 2×105 cells/mL are seeded in each well and Tetrahydrocurcumin, Curcumin and Calebin-A, at 0.1, 0.5, 1.0, 5.0, 10.0, 50.0 and 100.0 μM dissolved in DMSO, are added to their respective wells and incubated for 24, 48 and 72 h. The MTS reagent is added and incubated for 4 h. Absorbance is recorded at 490 nm in Synergy HT multi-well plate reader and Gen5 data analysis software[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Rats[1]
Surgically-modified, exposed jugular vein-catheterized, adult male CD Sprague-Dawley rats (250–300 g) ared used. Each rat is placed in a separate metabolic cage and fasted for 12 h prior to dosing with free access to water. On the day of experiment, the animals (N=3) receive a single dose of Tetrahydrocurcumin by oral gavage (500 mg/kg) in a volume not exceeding 1 mL. Animals have free access to water pre- and post-dosing, and food is provided 2 hours post-dosing. A series of blood samples (0.3 mL) are collected at 0, 15 and 30 min, and 1, 2, 4, 6, 12, 24, 48 and 72 h post-dose. At 72 h after administration, the animals are euthanized and exsanguinated. Immediately after each blood collection time point (except the terminal point), the cannula is flushed with 0.3 mL of 0.9% saline to replenish the collected blood volume. The dead volume of the cannula is replaced with sterile heparin/50% dextrose catheter lock solution to maintain the patency of the cannula as advised in the technical sheet supplied with the animals from Charles River. Following centrifugation of blood samples at 15,000 rpm for 5 min, serum is collected and placed into 2 mL tubes at -20°C until further analysis. Urine samples are collected at 0, 2, 6, 12, 24, 48 and 72 h post-dose and placed in 15 mL tubes. The exact urine volume of each sample is recorded then stored at -20°C until further analysis[1].

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.
