A novel homogenous assay for topoisomerase II action and inhibition

, 2005
Topoisomerase II is the only enzyme able to cleave and religate double-stranded DNA; this makes it essential for many vital functions during normal cell growth.

Effect of developmental changes on pharmacokinetics of drugs used in the treatment of infant acute lymphoblastic leukaemia—A comprehensive review

British Journal of Clinical Pharmacology, EarlyView.
While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

Benzothiazole derivatives as human DNA topoisomerase II alpha inhibitors

, 2013
Benzothiazole derivatives resembling the structure of DNA purine bases were tested to determine their topoisomerase inhibition activities. Based on DNA topoisomerase I and II relaxation assay results, all 12 derivatives acted as human topoisomerase II ...

Unsupervised machine learning for multi‐system adverse event pattern detection in pharmacovigilance: A proof‐of‐concept analysis of fluoroquinolone reports in FAERS

British Journal of Clinical Pharmacology, EarlyView.
. Aims Traditional pharmacovigilance detects single drug–event associations but cannot readily characterize multi‐system adverse‐event patterns such as fluoroquinolone‐associated disability. We evaluated unsupervised machine learning for this purpose, using fluoroquinolones as an exemplar.

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

Chemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Pharmacophore based discovery of dual inhibitors targeting TOP1 and TOP2A in resistant triple negative breast cancer

Discover Chemistry
Triple-negative breast cancer (TNBC) is an aggressive malignancy characterized by the absence of conventional hormonal receptors, leading to intrinsic resistance to standard therapies and poor clinical outcomes.

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Synthesis, Cytotoxicity, and Apoptosis‐Associated Cell Death Activity of an Isatin‐Containing Pyrimidine‐Derived Cu(II) Complex

Journal of Applied Toxicology, EarlyView.
ABSTRACT A Cu(II) complex derived from a pyrimidine with the isatin group was synthesized and tested for its cytotoxic effects on A549 lung cancer and MCF‐7 breast cancer cell lines, as well as its effects on apoptosis‐associated cell death and cell cycle regulation in A549 cells. To evaluate cytotoxicity, MTT assays were performed at 24, 48, and 72 h,
