BChE-IN-57

BChE-IN-57 is a mixed-type, selective BChE inhibitor with IC₅₀ values of 0.20 and 0.35 μM for eqBChE and hBChE, respectively. BChE-IN-57 reduces hydrogen peroxide-induced intracellular ROS accumulation and mitochondrial membrane potential loss through antioxidant protection. BChE-IN-57 inhibits the production of NO and pro-inflammatory cytokines and downregulates inflammatory enzyme markers. BChE-IN-57 chelates metal ions, including copper. BChE-IN-57 can be used for research on Alzheimer's disease.

For research use only. We do not sell to patients.

Innate Immunity

BChE-IN-57 (5-20 µM; 4 h) downregulates LPS-induced iNOS and COX-2 expression in BV2 cells^[1].

Innate Immunity

Cytokines and Chemokines

BChE-IN-57 (2.5-20 µM) dose-dependently inhibits LPS-induced production of NO, TNF-α, and IL-1β in BV2 cells^[1].

Oxidative Stress

BChE-IN-57 (1.25-10 μM; 4 h) protects HT22 cells against H₂O₂-induced loss of cell viability^[1].
BChE-IN-57 (5-10 µM; 4 h) inhibits H₂O₂-induced intracellular ROS accumulation in HT22 cells^[1].

Oxidative Stress

Mitochondrial Function

BChE-IN-57 (5-10 µM; 4 h) attenuates H₂O₂-induced mitochondrial membrane potential dissipation in HT22 cells^[1].

Others

BChE-IN-57 (Compound 6j) (10-20 min) potently inhibits eqBChE (IC₅₀ 0.20 µM) and hBChE (0.35 µM), with over 250-fold selectivity over eeAChE^[1].
BChE-IN-57 (100-400 nM; 20 min) inhibits eqBChE in a mixed-type manner with a K_i of 0.112 µM^[1].
BChE-IN-57 (6.25-100 µM) exhibits a favorable safety profile in HT22, BV2, and L02 cells, showing certain toxicity only at 50 and 100 µM^[1].

Cell Viability Assay^[1]

Cell Line:

HT22 cells
Concentration:

non-toxic concentrations (1.25-10 μM)
Incubation Time:

4 h (pre-incubation); 12 h (H2O2 exposure)
Result:

Improved the viability of H₂O₂-exposed cells to varying degrees.

Western Blot Analysis^[1]

Cell Line:

BV2 microglial cells
Concentration:

5, 10, 20 µM
Incubation Time:

4 h (pre-incubation)
Result:

LPS challenge significantly upregulated iNOS and COX-2.
At 20 µM, significantly downregulated both iNOS and COX-2 expression compared with the LPS-challenged group.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
