MAO A/HSP90-IN-2 (compound 4-C), a dual inhibitor of HSP90 and MAO A, exhibits IC50 values of 0.016 μM for MAO A and 4.58 μM for HSP90. This compound not only enhances HSP70 expression but also diminishes HER2 and phospho-Akt levels, and downregulates IFN-γ-induced PD-L1 expression in GL26 cells. Demonstrating efficacy against Temozolomide-sensitive and -resistant GBM cells, colon cancer, leukemia, non-small cell lung cancer, and other malignancies, MAO A/HSP90-IN-2 may also impede tumor immune evasion [1].

MAO-B-IN-19, a selective MAO-B inhibitor, exhibits neuroprotective and anti-inflammatory properties and demonstrates an IC50 value of 0.67 μM [1].

MAO-B-IN-27 (Compound 12c), a monoamine oxidase B (MAO-B) inhibitor, exhibits a potent and selective inhibitory effect on hMAO-B, with an IC50 value of 8.9 nM, and is utilized in Parkinson's disease (PD) research [1].

Norharmane (β-Carboline) is a natural β-carboline first isolated from plants of the Zygophyllaceae family.

J-147 is an experimental drug with reported effects against both Alzheimer's disease and ageing in mouse models of accelerated aging. It is a curcumin derivative and a potent neurogenic and neuroprotective drug candidate initially developed for the treatment of neurodegenerative conditions associated with aging that impacts many pathways implicated in the pathogenesis of diabetic neuropathy.
