GSK-J5 (hydrochloride)
目录号 : KCM12064 CAS No. : 1797983-32-4 纯度 : ≥95%
The histone H3 lysine 27 (H3K27) demethylase JMJD3 plays important roles in the transcriptional regulation of cell differentiation, development, the inflammatory response, and cancer. GSK-J4 is a cell-permeable prodrug which is modified by intracellular esterases to give GSK-J1 , an inhibitor of JMJD3. GSK-J5 is a pyridine regio-isomer of GSK-J4. Like GSK-J4, this isomer is cell-permeable and hydrolyzed to a free base. However, the free base is a weak inhibitor of JMJD3 (IC > 100 μM), making it an ideal inactive control molecule for elucidating the functional role of JMJD3 inhibition.

生物活性

GSK-J5 (hydrochloride) is a cell-permeable ester derivative of GSK J2, inactive. GSK-J5 hydrochloride is also an isomer of GSK-J4 and often used as a negative group.

体外研究

GSK-J5 (25 μM) has no effects at inhibiting the LPS-induced response of human primary macrophages derived from healthy volunteers. While GSK-J4 significantly reduced the expression of 16 of 34 LPS-driven cytokines as assessed by PCR array, such as TNF-α.
GSK-J5 (30 μM; 6 hours) is the inactive isomer of GSK-J4, has no effect on TNF-α protein production. But neither GSK-J4 nor GSK-J5 directly affects the levels of LPS-induced JMJD3 or of LPS-independent UTX and EZH2.
GSK-J5 (30 μM; 1 hour) can not prevent the LPS-induced loss of H3K27me3 associated with the TNFA TSS or block the recruitment of RNA polymerase II to this locus but GSK-J5 can. Finally, GSK-J4, but not GSK-J5, blocks the production of TNF-α by macrophages derived from patients with rheumatoid arthritis.
