Aβ-IN-7 (compound 5a) acts as a potent inhibitor of Aβ aggregation, stabilizing Aβ monomers at 50 μM concentration to prevent them from forming larger oligomers and delaying the nucleation phase. Comparative studies demonstrate that Aβ-IN-7 more effectively inhibits Aβ fibril formation than Aβ-IN-8 at identical 50 μM concentrations [1].
