<p>PAK4-IN-5 (Compound 12i) is a potent inhibitor of PAK4 (IC50: PAK4 at 7.68 nM, PAK1 at 1872.01 nM) that forms stable interactions with the PAK4 enzyme. This compound effectively inhibits the proliferation and migration potential of MDA-MB-231 cells by hindering the phosphorylation of PAK4 and LIMK1. Additionally, PAK4-IN-5 arrests the cell cycle in the G0/G1 phase, induces apoptosis, and prompts the production of reactive oxygen species. The LD50 in mice is greater than 500 mg/kg (oral).</p>

<p>Nitrovin is an antimicrobial growth promoter that induces ROS-mediated non-apoptotic and quasi-apoptotic cell death by targeting TrxR1. It exhibits anticancer activity with IC50 values ranging from 1.31 to 6.60 μM for both tumor and normal cells.</p>

<p>SMIP34 is an inhibitor of PELP1, binding to this target with a dissociation constant (Kd) of 37.4 μM. It demonstrates efficacy in inhibiting the proliferation of cancer cells and tumor progression. Specifically, SMIP34 is effective in breast cancer research, showing activity against wild-type (WT), mutant (MT) estrogen receptor-positive (ER+), and treatment-resistant (TR)-ER+ breast cancers.</p>

<p>Soquelitinib (CPI-818) is a selective ITK inhibitor， inhibits tumor growth,T-cell, up-regulatCXCR3, IFNγ, TNFα, and CD107a expression in normal CD8 cells.</p>

<p>p53 Activator 14 (Compound 7A) is a derivative of Neratinib that can induce DNA damage and activate p53, thereby inhibiting the proliferation of various cancer cells, with an IC50 of 7.21 μM for HCT116 cells. This compound hinders adhesion, migration, and invasion of HCT116 cells, disrupts the cell cycle, and triggers apoptosis. In addition, p53 Activator 14 exhibits anti-tumor properties and inhibits angiogenesis in the chick embryo chorioallantoic membrane (CAM) model.</p>

NDs-IN-1 (Compound 3g) is a novel non-covalent multi-target inhibitor that inhibits the activities of key enzymes such as hBACE-1, hAChE, and hMAO-B, and is primarily used in the study of neurodegenerative diseases [1].
