Modulation of Intestinal Transport and Absorption of Topotecan, a BCRP Substrate, by Various Pharmaceutical Excipients and Their Inhibitory Mechanisms of BCRP Transporter.

Journal of Pharmacy and Science, 2019
Breast cancer resistance protein transporter (ABCG2/BCRP) is highly expressed on the intestinal epithelial membrane and has a significant impact on the oral absorption of topotecan. In this study, we examined 6 pharmaceutical excipients including BL-9EX,

Clinical Pharmacokinetics of Topotecan

Clinical Pharmacokinetics, 1996
Topotecan (Hycamtin), a semisynthetic water-soluble derivative of camptothecin, is a potent inhibitor of DNA topoisomerase I in vitro and has demonstrated encouraging antitumour activity in a wide variety of tumours, including ovarian cancer and small cell lung cancer.

Small Molecule Inhibition of MicroRNA miR-21 Rescues Chemosensitivity of Renal-Cell Carcinoma to Topotecan.

Journal of Medicinal Chemistry, 2018
Chemical probes of microRNA (miRNA) function are potential tools for understanding miRNA biology that also provide new approaches for discovering therapeutics for miRNA-associated diseases. MicroRNA-21 (miR-21) is an oncogenic miRNA that is overexpressed

Isolation and structural confirmation of N -desmethyl topotecan, a metabolite of topotecan

Cancer Chemotherapy and Pharmacology, 1997
A sensitive high-performance liquid chromatography (HPLC) method for the determination of topotecan and total levels of topotecan (lactone plus its ring-opened hydroxycarboxylate form) was developed by the authors and used in several pharmacokinetics studies. During the analysis of plasma and urine samples collected in those studies, an additional peak

Topotecan in cervical cancer

International Journal of Gynecological Cancer, 2007
Recurrent and advanced cervical cancers are associated with high mortality and a lack of effective treatment options, especially for women who are poor candidates for surgery or radiation therapy. The broad clinical effectiveness and manageable toxicity of topotecan in other human malignancies as well as promising recent study results suggest that it ...

Topotecan-induced Bronchiolitis

Southern Medical Journal, 2004
Topotecan HCl is an antitumor drug exhibiting topoisomerase 1-inhibitory activity. Topotecan is used in the treatment of metastatic carcinoma of the ovary and as second-line treatment of small-cell lung cancer. Reported dose-limiting adverse reactions to topotecan are primarily hematologic in nature.
