SR18662 is a potent inhibitor of Krüppel-like factor five (KLF5) with an IC50 of 4.4 nM and an analogue of ML264 (HY-19994) with improved inhibitory potency against colorectal cancer cells. SR18662 can be used for the study of colorectal cancer[1].
SR18662 (0-10 μM; 24-72 hours) significantly reduces growth and proliferation of CRC cells as compared to treatment with vehicle control, ML264 (HY-19994). It shows improved efficacy in reducing viability of multiple CRC cell lines[1].SR18662 (10 μM; 24-72 hours) shows a significant increase in the number of apoptotic cells at both early and late states in DLD-1 and HCT116 cells[1].SR18662 (1 μM; 72 hours) reduces the expression of cyclins (cyclins E, A2, and B1) and components of MAPK (p-Erk) and WNT signaling pathways (p-GSK3 β) in cells[1].
SR18662 (intraperitoneal injection; 5-10 mg/kg; daily or twice daily; 5 days injection, days break, and 5 days) significantly reduces the growth of tumors in a mouse xenograft model[1].
