LDN0088050 is selectivity adipocyte fatty acid binding protein (AFABP, FABP4) inhibitor with Ki values of 0.29 and 1.3 μM for FABP4 and FABP3, respectively. LDN0088050 binds to FABP4 with a Kd of 2.05 μM[1]. Ki: 0.29 μM (FABP4), 1.3 μM (FABP3)[1]Kd: 2.05 μM (FABP4)[1] LDN0088050 significantly inhibits LPS-induced expression of both TNFα and IL-6 in RAW264.7 cells[1]. [1]. Zhou Y, et al.
