Preclinical pharmacology and clinical uses of topotecan

open access: yes, 1999
Topotecan, a soluble semisynthetic derivative of camptothecin, is a specific inhibitor of topoisomerase I and is endowed of potent antiproliferative effect in vitro and in vivo on tumoral cell lines as well as on endothelial cells. Moreover, topotecan is

Sustained Complete Response after Maintenance Therapy with Topotecan and Erlotinib for Recurrent Cervical Cancer with Distant Metastases

open access: yesCase Reports in Oncology, 2014
Introduction: Recurrent cervical cancer is associated with a poor prognosis. Most treatment responses are partial and of short duration. The development of new therapies is vital to improve treatment for recurrent disease.

A Phase Ib Case Series Using Bortezomib With Chemotherapy in Atypical Teratoid/Rhabdoid Tumors

open access: yesCancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT Background Atypical teratoid/rhabdoid tumors (ATRTs) are aggressive pediatric brain tumors that are sensitive to proteasome inhibitors in preclinical models. We evaluated the feasibility of combining the proteasome inhibitor, bortezomib, with chemotherapy.

Dual‐Drug‐Loaded Liposomes: Design Strategies, Mechanistic Insights, and Therapeutic Applications in Cancer

open access: yesMedComm – Biomaterials and Applications, Volume 5, Issue 3, September 2026.
Dual‐drug‐loaded liposomes enable the simultaneous delivery of hydrophilic and hydrophobic therapeutics to tumors, enhancing anticancer efficacy and overcoming multidrug resistance. Through rational formulation design and surface functionalization, these systems improve tumor targeting, modulate efflux mechanisms and EMT, and achieve synergistic ...

Mechanism-based models for topotecan-induced neutropenia

open access: yes, 2004
OBJECTIVE: A semiphysiologic pharmacokinetic-pharmacodynamic model was applied to describe topotecan-induced neutropenia, to quantify interindividual and intraindividual pharmacodynamic variability, and to study the effect of covariates on the model ...

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT
