TML-6 是一种口服有效的姜黄素衍生物,抑制 β-淀粉样前体蛋白和 β-淀粉样蛋白 (Aβ) 的合成。TML-6 上调 Apo E,抑制NF-κB和mTOR,并增加抗氧化Nrf2基因的活性。TML-6 具有用于阿尔茨海默氏病 (AD) 研究的潜力。
生物活性 | TML-6, an orally active curcumin derivative, inhibits the synthesis of the β-amyloid precursor protein andβ-amyloid (Aβ). TML-6 can upregulate Apo E, suppressNF-κBandmTOR, and increase the activity of the anti-oxidativeNrf2gene. TML-6 has the potential for Alzheimer’s disease (AD) research[1]. |
IC50& Target | |
体外研究 (In Vitro) | TML-6 (0.65-5.24 μg/mL; for 24 h) reduces the protein expression levels of APP and phospho-NF-κB, and induces the protein expression level of ApoE. TML-6 inhibits the mTOR signaling pathway through the suppression of phospho-mTOR[1]. TML-6 (0.31, 0.63, 2.5, 5, 10, 20 μM; 24 h) reveals no cytotoxicity in Huh-7 cells at concentrations below 5 μM and has an IC50of 4.19 μg/mL (8 μM)[1]. TML-6 (1.05, 2.09, 3.14, 4.19 μg/mL; 24 h) reduces the production of Aβ40 and Aβ42 between 1.05, 2.09 and 3.14 μg/mL (equal to 2, 4 and 6 μM) in a dose-dependent manner in N2a/APPswe cell[1]. TML-6 can exhibit transcriptional activation of the Nrf2 gene in a dose-dependent manner, with the highest activity at a concentration of 1.32 μg/mL[1].
Western Blot Analysis[1] Cell Line: | Huh-7 cells | Concentration: | 0.65, 1.31, 1.96, 2.61, 3.93, 5.24 μg/mL | Incubation Time: | For 24 hours | Result: | Reduced the amyloid precursor protein (APP) protein expression level by 60% and decreased the level of phosphorylated NF-κB by about 50% at a dose of 1.96 μg/mL after 24 h treatment. Induced the protein expression level of ApoE by approximately 44% at a dose of 2.62 μg/mL. |

体内研究 (In Vivo) | TML-6 (diet; 150 mg/kg/day; for four months) treatment results in significant improvement in learning, suppression of the microglial activation marker Iba-1, and reduction in Aβ in the brain[1]. TML-6 (oral; 150 mg/kg) has a T1/2of 1.27 hours, a Cmaxof 35.9 ng/mL and an AUC of 177 ngohr/mL[1].
Animal Model: | Six-month-old 3xTg (mutations: APPKM670/671NL, MAPTP301Land PSEN1M146V) AD transgenic mice[1] | Dosage: | 150 mg/kg | Administration: | Diet; daily; for four months | Result: | Improved the learning behaviors, significantly suppressed the Aβ levels and Iba-1 expression in the brain of 3xTg AD transgenic mice. |
Animal Model: | SD rats[1] | Dosage: | 150 mg/kg (Pharmacokinetic Analysis) | Administration: | Oral | Result: | Had a T1/2of 1.27 hours, a Cmaxof 35.9 ng/mL and an AUC of 177 ngohr/mL. |
