LCH-7749944 (CAT: I007632), also referred to as GNF-Pf-2356, is an innovative and potent inhibitor of PAK4 (p21-activated kinase 4). This compound demonstrates the capability to effectively hinder the proliferation of human gastric cancer cells by modulating the PAK4/c-Src/EGFR/cyclin D1 signaling pathway. The inhibition of this pathway is crucial in preventing the growth and proliferation of cancer cells, making LCH-7749944 a promising candidate for potential therapeutic applications in the treatment of gastric cancer.

LCH-7749944, a novel and potent p21-activated kinase 4 inhibitor, suppresses proliferation and invasion in human gastric cancer cells.Zhang J,Wang J,Guo Q,Wang Y,Zhou Y,Peng H,Cheng M,Zhao D,Li F, PMID: 22085492 DOI: 10.1016/j.canlet.2011.11.007 Abstract: P21-activated kinase 4 (PAK4), a serine/threonine protein kinase, has involved in the regulation of cytoskeletal reorganization, cell proliferation, gene transcription, oncogenic transformation and cell invasion. Moreover, PAK4 overexpression, genetic amplification and mutations were detected in a variety of human tumors, which make it potential therapeutic target. In this paper we found that LCH-7749944, a novel and potent PAK4 inhibitor, effectively suppressed the proliferation of human gastric cancer cells through downregulation of PAK4/c-Src/EGFR/cyclin D1 pathway. In addition, LCH-7749944 significantly inhibited the migration and invasion of human gastric cancer cells in conjunction with concomitant blockage of PAK4/LIMK1/cofilin and PAK4/MEK-1/ERK1/2/MMP2 pathways. Interestingly, LCH-7749944 also inhibited the formation of filopodia and induced cell elongation in SGC7901 cells. Importantly, LCH-7749944 caused successful inhibition of EGFR activity due to its inhibitory effect on PAK4. Taken together, these results provided novel insights into the development of PAK4 inhibitor and potential therapeutic strategies for gastric cancer.Copyright © 2011 Elsevier Ireland Ltd.
