KY02111 promotes differentiation of hPSCs to cardiomyocytes by inhibiting Wnt signaling, may act downstream of APC and GSK3β.
1 Customer Review
Transient Wnt inhibition results in persistent decrease of b-catenin. HTM cells were incubated for 4 days in serum-free media, treated with Wnt inhibitors for 8 days in serum free media, and recovered for 4 days in serum-free media before being fixed and stained for b-catenin. (B) HTM cells treated with 10 μM KY02111 or LGK-974 likewise show a reduction of b-catenin staining intensity. (CeD) Quantification of b-catenin staining intensity in HTM cells from 3 donors indicates a statistically significant decrease in intensity after 0.5 μg/mL SFRP1 (SFRP1), 10 μM KY02111, and 10 μM LGK-974. (E) Western blot shows increased T41 phosphorylation of b-catenin after SFRP1 or KY02111 treatment. Data presented as mean ± SEM. Significant difference from control using Tukey's method denoted by * p < 0.05; ***p < 0.001; using Student's T-test denoted by #p < 0.05. n=3. Scale bar 50 μm.

|Features||May act downstream of APC and GSK3β in the canonical WNT signaling pathway.|
KY02111 (10 μM) increases the ratio of beating cardiac colonies as much as 70%-94% in cell aggregates of two hESC lines (KhES-1 and KhES-3), four hiPSC lines (253G1, IMR90-1, IMR90-4, and RCHIPC0003), and a mouse ESC line (R1). KY02111 (10 μM) results in 73%-85% postive IMR90-1 hiPSCs expressing the cardiac markers, cardiac troponin T (cTnT), αActinin, or NKX2.5, whereas only a few DMSO-treated cells are positive for the markers. KY02111 (10 μM) results in 16% postive IMR90-1 hiPSCs expressing the cardiac pacemaker marker, HCN4, whereas the ratio of Vimentin-positive cells (fibroblasts) decreases 3.3-fold. KY02111-induced cardiomyocytes (KY-CMs) expresses the cardiac markers, αMHC, NKH2.5, and HCN4, and that all of the ion channel genes examined are expressed at levels similar to those of adult heart tissue. KY02111 (10 μM) downregulates the expression of 72.7% target genes of canonical WNT signaling in IMR90-1 hiPSCs, suggesting that KY02111 inhibits canonical WNT signaling in hPSCs. KY02111 (10 μM) clearly reduces luciferase activities in both IMR90-1 hiPSCs and HEK293 cells in a dose-dependent manner in the TOPflash assay. KY02111 (10 μM-25 μM) increases cardiac differentiation about 80-fold in transgenic monkey ESCs compared to the control and does not show toxicity to cells even at high concentration. KY02111 (10 μM) significantly reduces luciferase activity in the TOPflash assay in SW480 cells, whereas XAV939 and IWP-2 does not. KY02111 (10 μM) dramatically reduces luciferase activity induced by GSK3β inhibitor BIO in SW480 cells, compared to that of XAV939 and IWP-2. KY02111 alone produces approximately 80% cTnT-positive cells, KY02111 in combination with other WNT inhibitors does not significantly increase differentiation efficiency, which shows that KY02111 effectively produces a high proportion of functional cardiomyocytes from hPSCs.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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).
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 )
* 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.
