Bioactivity | SMS2-IN-1 is a potent and highly selective sphingomyelin synthase 2 (SMS2) inhibitor with an IC50 of 6.5 nM and a Kd of 37 nM. SMS2-IN-1 shows 150-fold selectivity for SMS2 over SMS1 (IC50 of 1000 nM)[1]. | ||||||||||||
Target | IC50: 6.5 nM (SMS2), 1000 nM (SMS1)Kd: 37 nM (SMS2) | ||||||||||||
Invitro | AS/MS binding experiments are conducted using these SMS2-mutant membrane fractions, SMS2-IN-1 (compound 2) binds to the S217A, H272A, and D276A mutants. S227 and H229 are pivotal amino acid residues for the binding of SMS2-IN-1 to SMS2[1]. | ||||||||||||
