FABP-IN-1 inhibits FABP3, FABP5, and FABP7 with Ki values of 0.69 μM, 0.55 μM and 0.67 μM, respectively. FABP-IN-1 displays potent antinociceptive effects. FABP-IN-1 is a high affinity fatty acid binding protein (FABP) inhibitor.
FABP5-IN-1 shows potent antinociceptive effects. FABP5-IN-1 is a selective and high affinity fatty acid binding protein 5 (FABP5) inhibitor with a Ki value of 1.7 μM, and does not bind to both FABP3 and FABP7.
