dna topoisomerase

DNA topoisomerase II inhibitor 1 is a potent inhibitor of DNA topoisomerase II that arrests the cell cycle in sub-G1 phase and induces apoptosis with anti-value-added effects.

Doxorubicin hydrochloride (Adriamycin) belongs to the anthracycline class of antibiotics and is an inhibitor of human DNA topoisomerase I II (IC50=0.8 2.67 μM). Doxorubicin hydrochloride exhibits cytotoxicity and antitumor activity. Doxorubicin hydrochloride reduces the phosphorylation of AMPK and its downstream target protein acetyl coenzyme A carboxylase, and induces apoptosis and autophagy.

Dxd (OQM5SD32BQ) is a potent inhibitor of DNA topoisomerase I with an IC50 of 0.31 μM. It is used as a conjugated drug of HER2-targeting ADC.

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.

Aldoxorubicin hydrochloride is an albumin-binding prodrug of Doxorubicin, a DNA topoisomerase II inhibitor. Aldoxorubicin hydrochloride is released from albumin under acidic conditions. Aldoxorubicin hydrochloride exhibits potent antitumor activities in various cancer cell lines and in murine tumor models.

DPBQ (ZINC1620467) is a p53 activator. DPBQ could activate p53 and trigger apoptosis in a polyploid-specific manner, without inhibition of topoisomerase or bind DNA.

Oxaquin TEA (MCB-3837 TEA), a precursor compound to MCB3681, is a DNA topoisomerase inhibitor that can be used to study Clostridium difficile infections and cross-infections.

DRF-1042, an orally active camptothecin analog, exhibits anticancer and insecticidal activities by inhibiting DNA topoisomerase I. It has been studied for its efficacy against solid tumors, including prostate and colon cancers.

DRF-1042 HCl is an orally active camptothecin analog with antitumor activity, inhibits DNA topoisomerase I, and is used in the study of refractory solid tumors.

AQ4 is a topoisomerase II inhibitor and DNA-inserting agent that displays antitumor activity in CRC cell lines.

Topixantrone 2HCl is a DNA topoisomerase inhibitor with antitumor activity for the study of gastric and prostate cancer.

XR 5944 is an antitumor compound that targets DNA, is a topoisomerase inhibitor, inhibits ER activity, and can be used to study colon and lung cancer.

Alalevonadifloxacin is a DNA gyrase and DNA topoisomerase inhibitor and a novel antibacterial compound of the quinolone class targeting MRSa. Alalevonadifloxacin is potentially useful in the treatment of bacterial Gram-positive, Gram-negative and anaerobic infections.

GPX-100 (13-deoxydoxorubicin) is an analogue of the anthracycline antitumour antibiotic doxorubicin. GPX-100 inserts into DNA and interacts with topoisomerase II to inhibit DNA replication and repair as well as RNA and protein synthesis.

Daniquidone (Batracylin) is a potent dual inhibitor of DNA topoisomerase I and DNA topoisomerase II with cytotoxic and antiproliferative activity that induces DNA fragmentation for the study of neoplasms, immune disorders, and lymphatic 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.

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

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

Irinotecan hydrochloride trihydrate (CPT-11 HCl Trihydrate) keeps DNA from unwinding by inhibiting topoisomerase 1.

Irinotecan Hydrochloride (CPT-11 hydrochloride) is the hydrochloride salt of a semisynthetic derivative of camptothecin. Irinotecan, a prodrug, is converted to a biologically active metabolite 7-ethyl-10-hydroxy-camptothecin (SN-38) by a carboxylesterase-converting enzyme. One thousand-fold more potent than its parent compound irinotecan, SN-38 inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks that inhibit DNA replication and trigger apoptotic cell death. Because ongoing DNA synthesis is necessary for irinotecan to exert its cytotoxic effects, it is classified as an S-phase-specific agent.

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.

Ofloxacin (Oxaldin) is a fluoroquinolone antibacterial antibiotic. Ofloxacin binds to and inhibits bacterial topoisomerase II (DNA gyrase) and topoisomerase IV, enzymes involved in DNA replication and repair, resulting in cell death in sensitive bacterial species.

Nalidixic acid (NSC-82174) is a synthetic 1, 8-naphthyridine antimicrobial agent with a limited bacteriocidal spectrum. It is an inhibitor of the A subunit of bacterial DNA GYRASE.
