Product Description

MK-7145 is a novel, potent, selective and orally bioactive ROMK inhibitor with IC50 of 0.045 μM and has the potential for the treatment of hypertension and heart failure. ROMK, the renal outer medullary potassium channel, is involved in potassium recycling at the thick ascending loop of Henle and potassium secretion at the cortical collecting duct in the kidney nephron. Because of this dual site of action, selective inhibitors of ROMK are expected to represent a new class of diuretics/natriuretics with superior efficacy and reduced urinary loss of potassium compared to standard-of-care loop and thiazide diuretics. MK-7145 is selective against other cardiac ion channels such as Cav1.2 and Nav1.5 (IC50 > 30 μM). MK-7145 was not a potent reversible inhibitor of human CYP3A4, CYP2C9, or CYP2D6 (IC50 > 50μM) and was not a time-dependent inhibitor of CYP3A4 at 10and 50 μM. MK-7145 caused dose-dependent lowering of blood pressure in a subchronic SHR model. MK-7145 is the first small molecule ROMK inhibitor to enter clinical development.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
MK-7145 (compound 12) was evaluated against other Kir channel family members. Even at doses as high as 30 μM, it shows no discernible action on the Kir2.1, Kir2.3, Kir4.1, or Kir7.1 channels. Additionally, MK-7145 exhibits selectivity for additional cardiac ion channels, including Nav1.5 and Cav1.2 (IC50>30 μM). Using HEK293 cells that were transfected with human SERT, MK-7145 inhibited 3H-serotonin uptake with an IC50 value of 2.40±0.32 μM (n=5). This was based on an extensive counterscreen panel that included over 150 receptors, enzymes, and ion channels. Only three activities at <10 μM were shown by MK-7145: acetylcholinesterase, ACES, IC50=9.94 μM, growth inhibitory isoform 1, sst1, IC50=2.63 μM, and human serotonin transporter, SERT, IC50=0.12 μM. Because MK-7145 is a substrate of human Pgp (human Mdr1 BAAB ratio = 12), in addition to its greater ROMK potency and in vivo efficiency, it should offer a sizable safety window for SERT off-target activities.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
