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.

TopoII/tubulin-IN-1 (Compound 1B8) is an inhibitor of TopoII/tubulin. It effectively suppresses the proliferation of tumor cells and reduces ROS levels, while inducing apoptosis and cell cycle arrest, without showing significant cytotoxicity to normal cells. TopoII/tubulin-IN-1 exhibits antitumor activity.

Doxorubicin hydrochloride is an anthracycline antibiotic with cytotoxic and antitumor activity. It is an effective inhibitor of human DNA topoisomerase I and II, with IC50 values of 0.8 μM and 2.67 μM, respectively. In addition to inhibiting DNA topoisomerases, it can reduce the phosphorylation of AMPK and its downstream target, acetyl-CoA carboxylase. Doxorubicin hydrochloride also induces apoptosis and autophagy. In animal studies, it is commonly used to induce models of acute renal failure, chronic kidney injury, and heart failure.

Suramin Sodium Salt (BAY-205) is a sodium salt form of suramin, a polysulphonated naphthylurea with potential antineoplastic activity. Suramin blocks the binding of various growth factors, including insulin-like growth factor I (IGF-I), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and tumor growth factor-beta (TGF-beta), to their receptors, thereby inhibiting endothelial cell proliferation and migration. This agent also inhibits vascular endothelial growth factor (VEGF)- and basic fibroblast growth factor (bFGF)-induced angiogenesis; retroviral reverse transcriptase; uncoupling of G-proteins from receptors; topoisomerases; cellular folate transport; and steroidogenesis.

Ellipticine (Elliptisine) is a potent antineoplastic agent exhibiting multiple mechanisms of action, IC50 of 0.67±0.06, 1.25±0.13, 1.25±0.13, 0.67±0.06, 0.27±0.02, 0.49±0.04, 0.44±0.03, and 1.48±0.62 μM for Leukemia HL-60, Breast adenocarcinoma MCF-7, Breast adenocarcinoma MCF-7, Leukemia HL-60, Neuroblastoma IMR-32, Neuroblastoma UKF-NB-4, Neuroblastoma UKF-NB-3, and Glioblastoma U87 mg cell, respectively.

Chloroquinoxaline sulfonamide (Chloroquinoxaline) is a topoisomerase II alpha/beta toxin with antitumor activity and immunosuppressive properties that inhibits the proliferation of B16 melanoma cells in mice, and can be used to study metastatic colorectal cancer. It can be used to study metastatic colorectal cancer.

Leurubicin (N-Leucyldoxorubicin) is a potential Top II inhibitor for the study of bacterial infections .

F-14512 (free base) is a topoisomerase II inhibitor for the study of acute myeloid leukemia.

Pyrazoloacridine (PD 115934) is a nucleic acid binding agent that inhibits the activity of topo I and II with an IC50 of 1.25 μM in K562 cells. Pyrazoloacridine shows anti-cancer activity.

Ledoxantrone trihydrochloride is a Top II inhibitor with anticancer activity and is used in the study of digestive disorders and urologic disorders.

Etoposide (VP-16-213) is a topoisomerase II inhibitor that inhibits DNA synthesis by forming a complex with topoisomerase II and DNA (IC50=60.3 μM). Etoposide has antitumor activity and induces apoptosis and autophagy.

Mitoxantrone dihydrochloride (NSC-301739) is the hydrochloride salt of an anthracenedione antibiotic with antineoplastic activity. It is a type II topoisomerase inhibitor.

Ciprofloxacin monohydrochloride (Bay-09867 hydrochloride) is a broad-spectrum antimicrobial carboxyfluoroquinoline.

Moxifloxacin hydrochloride (BAY12-8039 HCl) is a fourth generation fluoroquinolone with expanded activity against gram-positive bacteria as well as atypical pathogens. Moxifloxacin has been linked to mild ALT elevations during therapy and to rare instances of idiosyncratic acute liver injury with symptoms and jaundice.

Pefloxacin Mesylate Dihydrate (1589 RB) , an antibacterial agent, restrains bacterial DNA replication by inhibiting DNA gyrase (topoisomerase).

Enoxacin hydrate (AT-2266 hydrate) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent.

Enoxacin (NSC-629661) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent (fluoroquinolones) structurally related to nalidixic acid.
