TML-6, an orally active curcumin derivative, inhibits the synthesis of the β-amyloid precursor protein and β-amyloid (Aβ). TML-6 can upregulate Apo E, suppress NF-κB and mTOR, and increase the activity of the anti-oxidative Nrf2 gene. TML-6 has the potential for Alzheimer’s disease (AD) research[1].
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 IC50 of 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].
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 T1/2 of 1.27 hours, a Cmax of 35.9 ng/mL and an AUC of 177 ng•hr/mL[1].

The Beneficial Effects of Combining Anti-Aβ Antibody NP106 and Curcumin Analog TML-6 on the Treatment of Alzheimer's Disease in APP/PS1 Mice
Int J Mol Sci 2022 Jan 5;23(1):556.PMID:35008983DOI:10.3390/ijms23010556.
Alzheimer's disease (AD) is a progressive neurodegenerative disease with a multifactorial etiology. A multitarget treatment that modulates multifaceted biological functions might be more effective than a single-target approach. Here, the therapeutic efficacy of combination treatment using anti-Aβ antibody NP106 and curcumin analog TML-6 versus monotherapy was investigated in an APP/PS1 mouse model of AD. Our data demonstrate that both combination treatment and monotherapy attenuated brain Aβ and improved the nesting behavioral deficit to varying degrees. Importantly, the combination treatment group had the lowest Aβ levels, and insoluble forms of Aβ were reduced most effectively. The nesting performance of APP/PS1 mice receiving combination treatment was better than that of other APP/PS1 groups. Further findings indicate that enhanced microglial Aβ phagocytosis and lower levels of proinflammatory cytokines were concurrent with the aforementioned effects of NP106 in combination with TML-6. Intriguingly, combination treatment also normalized the gut microbiota of APP/PS1 mice to levels resembling the wild-type control. Taken together, combination treatment outperformed NP106 or TML-6 monotherapy in ameliorating Aβ pathology and the nesting behavioral deficit in APP/PS1 mice. The superior effect might result from a more potent modulation of microglial function, cerebral inflammation, and the gut microbiota. This innovative treatment paradigm confers a new avenue to develop more efficacious AD treatments.
A Curcumin Analog Exhibits Multiple Biologic Effects on the Pathogenesis of Alzheimer's Disease and Improves Behavior, Inflammation, and β-Amyloid Accumulation in a Mouse Model
Int J Mol Sci 2020 Jul 30;21(15):5459.PMID:32751716DOI:10.3390/ijms21155459.
Drugs for the treatment of Alzheimer's disease (AD) are in urgent demand due to the unmet need and the social burden associated with the disease. Curcumin has been historically considered as a beneficial product for anti-aging and AD. However, many efforts to develop curcumin for clinical use are hindered mainly due to its poor bioavailability. Recent development in drug delivery and structural design has resolved these issues. In this study, we identified a small molecule, TML-6, as a potential drug candidate for AD through screening a panel of curcumin derivatives using six biomarker platforms related to aging biology and AD pathogenesis. The structural modification of TML-6 is designed to improve the stability and metabolism of curcumin. Cell biological studies demonstrated that TML-6 could inhibit the synthesis of the β-amyloid precursor protein and β-amyloid (Aβ), upregulate Apo E, suppress NF-κB and mTOR, and increase the activity of the anti-oxidative Nrf2 gene. In the 3x-Tg AD animal model, TML-6 treatment resulted in significant improvement in learning, suppression of the microglial activation marker Iba-1, and reduction in Aβ in the brain. Although TML-6 exhibited a greater improvement in bioavailability as compared to curcumin, formulation optimization and toxicological studies are under development to assure its druggability. Taken together, TML-6 meets the current strategy to develop therapeutics for AD, targeting the combination of the Aβ cascade and aging-related biology processes.
