BuChE-IN-TM-10 targets butyrylcholinesterase (BuChE) (IC50 = 0.08 μM; Ki = 0.05 μM, competitive inhibition mode) [1]
BuChE-IN-TM-10 targets acetylcholinesterase (AChE) (IC50 = 3.2 μM; Ki = 2.8 μM, mixed inhibition mode) [1] BuChE-IN-TM-10 targets β-amyloid (Aβ) aggregation (IC50 = 2.1 μM for inhibiting Aβ1-42 fibril formation) [1] |
|---|---|
| ln Vitro |
- BuChE inhibitory activity: BuChE-IN-TM-10 exhibited potent and selective BuChE inhibition with an IC50 of 0.08 μM, which was 40-fold more potent than AChE inhibition (IC50 = 3.2 μM). Kinetic analysis confirmed competitive inhibition of BuChE (Ki = 0.05 μM) and mixed inhibition of AChE (Ki = 2.8 μM) [1]
- Aβ aggregation inhibition: BuChE-IN-TM-10 dose-dependently inhibited Aβ1-42 fibril formation, with an IC50 of 2.1 μM. At 5 μM, it reduced Aβ1-42 aggregation by 78% compared to the control, as detected by Thioflavin T (ThT) fluorescence assay. Transmission electron microscopy (TEM) confirmed the reduction of Aβ1-42 fibril formation [1] - Neuroprotective activity: BuChE-IN-TM-10 protected SH-SY5Y cells against Aβ1-42-induced cytotoxicity. At concentrations of 1 μM, 5 μM, and 10 μM, the cell viability was increased by 23%, 45%, and 62% respectively, compared to Aβ1-42-treated cells (viability = 52% of normal control) [1] - Antioxidant activity: BuChE-IN-TM-10 scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals with an IC50 of 8.7 μM, and reduced reactive oxygen species (ROS) levels in Aβ1-42-treated SH-SY5Y cells by 56% at 10 μM [1] |
| Enzyme Assay |
- BuChE/AChE inhibition assay: Reaction mixtures were prepared by mixing acetylthiocholine iodide (for AChE, 1 mM) or butyrylthiocholine iodide (for BuChE, 1 mM), enzyme solution (AChE or BuChE, 0.01 U/mL), and BuChE-IN-TM-10 at gradient concentrations (0.01-10 μM) in Tris-HCl buffer (pH 8.0). The mixture was incubated at 37°C for 15 minutes, then 5,5'-dithio-bis-(2-nitrobenzoic acid) (DTNB) was added to detect thiocholine production. Absorbance was measured at 412 nm, and IC50 values were calculated. Kinetic parameters were determined by varying substrate concentrations (0.25-4 mM) with fixed drug concentrations [1]
- Aβ1-42 aggregation inhibition assay: Aβ1-42 peptide was dissolved in hexafluoroisopropanol, lyophilized, and reconstituted in phosphate-buffered saline (pH 7.4) to a concentration of 100 μM. BuChE-IN-TM-10 (0.1-10 μM) was mixed with Aβ1-42 solution, incubated at 37°C for 48 hours. ThT (20 μM) was added, and fluorescence intensity was measured at excitation 446 nm/emission 490 nm. For TEM analysis, samples were stained with uranyl acetate and observed under a transmission electron microscope [1] - DPPH radical scavenging assay: BuChE-IN-TM-10 (1-50 μM) was mixed with DPPH solution (0.1 mM) in ethanol, incubated at room temperature for 30 minutes. Absorbance was measured at 517 nm, and the scavenging rate was calculated. Ascorbic acid was used as a positive control [1] |
| Cell Assay |
- Cell viability and neuroprotection assay: SH-SY5Y cells were seeded into 96-well plates at a density of 1×10⁴ cells/well and incubated overnight. For cytotoxicity testing, BuChE-IN-TM-10 (0.1-50 μM) was added and incubated for 48 hours. For neuroprotection testing, cells were pre-treated with BuChE-IN-TM-10 (1-10 μM) for 2 hours, then Aβ1-42 (20 μM) was added and incubated for 48 hours. Cell viability was measured using a tetrazolium salt-based colorimetric assay, with absorbance detected at 490 nm [1]
- ROS detection assay: SH-SY5Y cells were seeded into 24-well plates at 5×10⁴ cells/well, incubated overnight. Cells were pre-treated with BuChE-IN-TM-10 (1-10 μM) for 2 hours, then Aβ1-42 (20 μM) was added and incubated for 24 hours. Cells were loaded with a ROS-sensitive fluorescent probe for 30 minutes, washed, and fluorescence intensity was measured at excitation 488 nm/emission 525 nm using a microplate reader [1] |

| Additional Infomation |
Chemical properties: BuChE-IN-TM-10 is a ferulic acid derivative with a molecular weight of 437.52 Da. It has high solubility in DMSO (≥ 20 mM) and methanol (≥ 10 mM) and a purity of ≥ 98% [1] - Mechanism of action: BuChE-IN-TM-10, as a multi-target ligand, treats Alzheimer's disease through three mechanisms: inhibiting BuChE/AChE to restore cholinergic function; inhibiting Aβ1-42 aggregation to reduce neurotoxicity; and scavenging reactive oxygen species (ROS) to alleviate oxidative stress [1] - Selectivity: BuChE-IN-TM-10 has a much higher selectivity for BuChE than for AChE (selectivity index = 40), which helps reduce the side effects associated with excessive AChE inhibition [1]
Structural features: The compound contains a ferulic acid moiety (which has antioxidant and anti-amyloid formation activity) and a benzylpiperidine moiety (which has cholinesterase inhibitory activity), which gives it multi-target activity [1] |
