Biological Activity

Description LDC000067 is a highly selective CDK9 inhibitor with IC50 of 44 nM, 55/125/210/ >227/ >227-fold selectivity over CDK2/1/4/6/7.
Features CDK9-selective inhibitor.
Targets
CDK9 [1]
(Cell-free assay)
CDK2 [1]
(Cell-free assay)
44 nM 2.441 μM
In vitro

LDC000067 reduces Ser2-P, induces p53 activation and leads to apoptosis in mESCs. In addition, LDC067 also dose-dependently inhibits P-TEFb-dependent de novo RNA synthesis of cellular genes.[1]

(D) The expression of proteins involved in the CDK9-signaling pathway in the U2OS osteosarcoma cell line was examined by Western blotting after 48 h of LDC067 treatment. (E) Semiquantitative analysis of (D) densitometry relative to tubulin. The data represent the mean ± SE of the experiment carried out in triplicate. (F) The expression of proteins involved in the CDK9-signaling pathway in the KHOS osteosarcoma cell line was examined by Western blotting after 48 h of LDC067 treatment. (G) Semiquantitative analysis of (F) densitometry relative to tubulin. The data are mean ± SE of the experiment carried out in triplicate.

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)

*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 )

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.
