Src family kinase (SFK) is a family of non-receptor tyrosine kinases including nine members: Src, Yes, Fyn, and Fgr, forming the SrcA subfamily, Lck, Hck, Blk, and Lyn in the SrcB subfamily, and Frk in its own subfamily. In immune cells, Src-family kinases (SFKs) have been implicated as critical regulators of a large number of intracellular signaling pathways. Src-family kinases (SFKs) occupy a proximal position in numerous signaling transduction cascades including those emanating from the T and B cell antigen receptors, Fc receptors, growth factor receptors, cytokine receptors, and integrins. In addition to these positive regulatory roles, Src-family kinases (SFKs) can also function as negative regulators of cellular signaling by phosphorylating immunoreceptor tyrosine-based inhibitory motifs (ITIMs) on inhibitory receptors, resulting in recruitment and activation of inhibitory molecules such as the phosphatases SHP-1 and SH2 containing 5′ inositol phosphatase (SHIP-1).

MCB-613

MCB-613 is a potent, pan steroid receptor coactivator (SRC) stimulator.Target: SRCin vitro: MCB-613 exerts the greatest activation of SRC-1 in the primary screen, is confirmed to be a strong activator of all three SRCs. MCB-613 can super-stimulate SRCs' transcriptional activity. MCB-613 increases SRCs' interactions with other coactivators and markedly induces ER stress coupled to the generation of reactive oxygen species (ROS). MCB-613 selectively and reversibly binds to the RID of SRC-3, and selectively kills cancer cells including MCF-7 (breast), PC-3 (prostate), H1299 (lung), and HepG2 (liver) cells, without toxicity to mouse primary hepatocytes and mouse embryonic fibroblasts (MEFs). MCB-613 also increases SRCs' interactions with other coactivators and markedly induces ER stress coupled to the generation of reactive oxygen species (ROS). [1]in vivo: In an MCF-7 breast cancer mouse xenograft model, MCB-613 (20 mg/kg, i.p.) significantly and dramatically inhibits the growth of the tumor while causing no obvious animal toxicity and body weight less.
