Biochem/physiol Actions

WH-4-023 (KIN112) is a potent and selective inihbitor of the tyrosine kinases Lck and Src with IC50 values of 2 nM for Lck and 6 nM for Src. WH-4-023 is a somewhat less potent inhibitor of salt-inducible kinases (SIKs) with IC50 values of 10, 22 and 60 nM for SIK 1, 2 and 3 respectively. WH-4-023 was found to support self-renewal of naive human embryonic stem cells, in particular in combination with PD 0325901 (PZ0162), CHIR99021 (SML1046), and SB-590885 (SML0501).
WH-4-023 belongs to the Src kinase family. It stimulates apoptosis in GC-resistant T-acute lymphoblastic leukemia (T-ALL) cells.

Rationale: SOX10 (SRY-related HMG-box 10) and MITF-M (microphthalmia-associated transcription factor M) restrict the expression of melanogenic genes, such as TYR (tyrosinase), in melanocytes. DACE (diacetylcaffeic acid cyclohexyl ester) inhibits melanin production in α-MSH (α-melanocyte stimulating hormone)-activated B16-F0 melanoma cells. In

Naive Pluripotent Stem Cell Culture in an Inhibitor Based 2i/LIF Containing Serum-Free and Feeder-Free Stem Cell Media

Naive pluripotent stem cells are located within the epiblast of mature blastocysts. These primitive “ground-state” cells may be cultured in vitro using specialized media and small molecule inhibitors.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
