MK-3328 is a β-Amyloid PET ligand, which exhibits high binding potency with an IC50 of 10.5 nM.
MK-3328 exhibits amyloid binding potency balanced with low levels of nonspecific binding[1].
In vivo, [18F]MK-3328 demonstrates favorable kinetics, exhibiting high brain uptake and good washout in normal rhesus monkey positron emission tomography (PET) imaging studies[1].

Kinase experiment: | [3H]-DMAB is synthesized at a specific activity of ~80 Ci/mmol. The final concentration of radioligand for tissue homogenate binding assay is 1.5nM. Brain homogenates are diluted with PBS to 0.4 mg/mL from original 10 mg/mL volume and 200 μL is used in assay for a final concentration of 50 μg/assay tube. Unlabeled test compounds are dissolved in DMSO at 1 mM. Dilution of test compound (e.g., MK-3328) to various concentrations is made with PBS containing 2% DMSO. Total binding is defined in the absence of competing compound, and non-displaceable binding is determined in the presence of 1 μM unlabeled self block. Compound dilutions (10×) are added into the assay tube (25 μL each/per tube, separately) containing 200 μL brain homogenate dilution, and the tubes are pre-incubated at room temperature for 10 minutes. Then radioligand dilutions (10×) are added into the assay tube (25 μL each/per tube, separately) to a final volume of 250 μL per tube. Incubation is carried out at room temperature (25°C) for 90 minutes, and then the assay samples are filtered onto GF/C filters using Skatron 12 well harvester, washing on setting 5-5-5 (~ 3×2 mL) ice cold buffer (PBS, pH 7.4). GF/C filter papers for the Skatron harvester are pre-soaked in 0.1% BSA for 1 hour at room temperature before use. Filters are punched into scintillation vials and counted in 2 mL Ultima Gold on Perkin Elmer Tri-Carb 2900TR for 1 minute. The data analysis is done with Prism software. All assays are done in triplicate, and in the laboratory designated for studies using human tissues[1]. |

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
