E4888New Guanabenz hydrochloride Guanabenz hydrochloride(NE56490) is a small molecule, antihypertensive agonist of α2-adrenoceptor. It also inhibits eIF2α and GADD34, showing potential for treating cardiac hypertrophy, heart failure, atherosclerosis, and ischemic heart disease.
S6533 Briciclib Briciclib (ON-014185) is a water soluble derivative of ON-013100, a small molecule that binds to and inhibits eukaryotic translation initiation factor 4E (eIF4E).
S8994 Zotatifin Zotatifin (eFT226) is a highly effective and sequence-selective inhibitor of the RNA helicase eIF4A. It promotes eIF4A binding to specific mRNA sequences with recognition motifs in the 5'-UTRs, with an IC50 of 2 nM, and disrupts the assembly of the eIF4F initiation complex. By enhancing the interaction between eIF4A and polypurine RNA sequence or structural motifs, zotatifin converts eIF4A into a sequence-specific translation repressor, thereby regulating the translation of certain target genes. It also exhibits anti-tumor activity.
S2961 GC7 Sulfate GC7 (N1-guanyl-1,7-diaminoheptane) Sulfate is an inhibitor of deoxyhypusine synthase (DHPS). GC7 inhibits Neuroblastoma (NB) cell proliferation in a dose-dependent manner, through induction of the cell cycle inhibitor p21 and reduction of total and phosphorylated Rb proteins.
