Topoisomerases and cancer chemotherapy: recent advances and unanswered questions [version 1; peer review: 3 approved]

F1000Research, 2019
DNA topoisomerases are enzymes that catalyze changes in the torsional and flexural strain of DNA molecules. Earlier studies implicated these enzymes in a variety of processes in both prokaryotes and eukaryotes, including DNA replication, transcription ...

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 ...

Organelle‐Resolved Tetrazine‐trans‐Cyclooctene Click Chemistry for Cargo Delivery and Release

Chemistry – A European Journal, EarlyView.
Bioorthogonal click chemistry tools provide a means for specific intracellular conjugation of molecules. In this study, we used reactive tetrazine (Tz) and TCO moieties for labeling of organelles and organelle‐specific delivery and activation of doxorubicin prodrugs.

Trapping of the transport-segment DNA by the ATPase domains of a type II topoisomerase

Nature Communications, 2018
Type 2 topoisomerases alter DNA supercoiling by an ATP-dependent reaction involving DNA passage through a cleaved DNA duplex. Here the authors present the crystal structure of the ParE ATPase domains of S.

Methanosarcina acetivorans C2A topoisomerase IIIα, an archaeal enzyme with promiscuity in divalent cation dependence. [PDF]

PLoS ONE, 2011
Topoisomerases play a fundamental role in genome stability, DNA replication and repair. As a result, topoisomerases have served as therapeutic targets of interest in Eukarya and Bacteria, two of the three domains of life.

Payload‐Based Clinical Pharmacology Review of Approved Antibody–Drug Conjugates: Commonalities and Considerations for Streamlined Development

Clinical Pharmacology &Therapeutics, EarlyView.
Antibody–drug conjugates (ADCs) combine the specificity of an antibody with the potency of a cytotoxic drug. Thirteen ADCs, utilizing seven unique cytotoxic payloads and targeting 11 distinct antigens, are currently approved by the US Food and Drug Administration as of June 2025, representing a rapidly growing and highly promising class of anticancer ...

1‐(Acetylamino)thioxanthones and Derivatives: Synthesis From 1‐Halogenothioxanthones and Biological Properties

European Journal of Organic Chemistry, EarlyView.
The conversion of 1‐halogenothioxanthones into 1‐(acetylamino) derivatives and their NaH‐mediated cyclization have been optimized. This rapid method yields thiochromeno[4,3,2‐de]quinol‐2‐ones that exhibit promising in vitro anticancer activity.
