Biological Activity

Description CID755673 is a cell-active pan-PKD1/2/3 inhibitor with IC50 of 180 nM, 280nM, and 227 nM, respectively, about 200-fold selectivity over other CAMKs.

In vitro

In LNCaP prostate cancer cells, CID755673 directly inhibits PKD1 activity. In HeLa cells, CID755673 significantly blocks PMA-induced nuclear export of HDAC5, and blocks PKD-mediated protein transport. In prostate cancer cells, CID755673 potently blocks cell migration and invasion, and also shows inhibition activity on tumor cell proliferation and cell cycle distribution. [1] In addition, CID755673 alter primary human NK cell effector functions. [3]

In vivo CID755673, via PKD/PKD1 inhibition, significantly ameliorates necrosis and severity of pancreatitis in a rat acute pancreatitis model. [2]


Kinase Assay: [1]
- Collapse

In Vitro Radiometric PKD Kinase Assay:

The radiometric kinase assay is carried out by coincubating 0.5 μCi of [γ-32P]ATP, 20 μM ATP, 50 ng of purified recombinant human PKD (PKD1, PKD2, and PKD3) or CAMKIIα proteins, and 2.5 μg of Syntide-2 in 50 μl of kinase buffer that contains 50 mM Tris-HCl, pH 7.5, 4 mM MgCl2, 10 mM β-mercaptoethanol. The reaction is carried out under conditions that the initial rate is within the linear kinetic range. The filter papers are then washed three times in 0.5% phosphoric acid, air-dried, and counted using a Beckman LS6500 multipurpose scintillation counter.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
