Sertindole (Lu 23-174) is an atypical antipsychotic that binds to dopamine D2 receptors and serotonin (5-HT) receptor subtypes 5-HT1D, 5-HT2A, and 5-HT2C, with Kds of 2.7, 20, 0.14, and 6 nM, respectively.

Doxycycline is an orally active tetracycline antibiotic with broad-spectrum inhibitory effects on matrix metalloproteinases (MMPs), possessing both antibacterial and antitumor activities, and is commonly used in inducible gene expression ON-OFF systems.

Doxycycline (hyclate) is an orally active tetracycline antibiotic with broad-spectrum inhibitory activity against matrix metalloproteinases (MMPs), possessing both antibacterial and antitumor properties, and is commonly used in inducible gene expression ON-OFF systems.

Talazoparib (LT-673) is a new-type PARP inhibitor (IC50: 0.58 nM), It similarly binds to PARP1/2 (Kis: 1.2/0.85 nM).

WEE1-IN-11 (Compound 13) serves as a potent CDK2 inhibitor with an IC50 of 2.0 nM. It exhibits inhibitory effects on several cell lines, including NCI-H446, A427, OVCAR3, C33A, and WiDr, with respective IC50 values of 93.9, 34.5, 86.7, 23.1, and 85 nM.

Topo I II-IN-2 (Compound 3g) is an inhibitor of both Topo I and Topo II. It exhibits inhibitory activity against NCI-H446 and NCI-H1048 cells with IC50 values of 1.30 μM and 1.42 μM, respectively. Topo I II-IN-2 induces mitochondrial apoptosis, disrupts mitochondrial function, and stimulates activity generation. Additionally, it inhibits the PI3K Akt mTOR pathway, effectively preventing the proliferation, invasion, and migration of small cell lung cancer (SCLC) cells in vitro.

PROTAC CDK9 degrader-11 (Compound C3) is an orally active PROTAC CDK9 degrader with a DC50 of 1.09 nM. This compound exhibits cytotoxicity in small cell lung cancer (SCLC) cells, with IC50 values in the nanomolar range. It induces cell cycle arrest at the G0 G1 phase and inhibits cell invasion in DMS114 and DMS53 cells. In addition, PROTAC CDK9 degrader-11 shows antitumor activity in an NCI-H446 xenograft mouse model.
