SMILES: O=C(NC1=C(F)C=C(C2=CN(C3CC3)C4=C2C(N)=NC=N4)C=C1)NC5=NOC(C6(C(F)(F)F)CC6)=C5
Biological Activity: Ofirnoflastum (Ofirnoflast) is an orally active first-in-class allosteric NEK7 inhibitor with an IC50 of 46 nM. Ofirnoflastum binds an allosteric site adjacent to NEK7’s ATP-binding pocket, induces conformational shifts, disrupts NEK7-NLRP3 binding, blocks NLRP3 inflammasome assembly, spares NEK7’s physiological functions, and suppresses caspase-1, caspase-8, NF-κB, and TNF activity. Ofirnoflastum reduces pro-inflammatory cytokine production, suppresses ASC specks, IL-1β release, pyroptotic cell death, and leukemic burden, induces apoptosis and erythroid differentiation, restores hematopoiesis, and improves outcomes in colitis models. Ofirnoflastum can be used for the research of myelodysplastic syndromes, chronic myelomonocytic leukemia, and acute myeloid leukemia[1][2][3][4][5].
