Description

General description

A potent and specific inhibitor of MEK1 (IC₅₀ = 72 nM) and MEK2 (IC₅₀ = 58 nM). The inhibition is noncompetitive with respect to both ATP and ERK. Has very little effect on other kinases such as Abl, Cdk2, Cdk4, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, PKC, and Raf. Also acts as an immunosuppressant by effectively blocking IL-2 synthesis and T cell proliferation without affecting the long-term outcomes of either T cell activation or tolerance. Reported to undergo rapid isomerization in DMSO and exist as an equilibrium mixture of (Z,Z), E,E) and (Z,E) isomers with minimal loss of activity over a period of 1 month.

Downregulation of microRNA‑143 promotes osteogenic differentiation of human adipose‑derived mesenchymal stem cells through the k‑Ras/MEK/ERK signaling pathway.

Yiming Zhang et al.

International journal of molecular medicine, 46(3), 965-976 (2020-06-26)

MicroRNAs (miRNAs) are known to have regulatory roles in the osteogenic differentiation of various mesenchymal stem cells (MSCs), although their regulatory role on human adipose‑derived mesenchymal stem cells (hADSCs) remains unclear. The aim of the present study was to investigate
