The therapeutic effects of intraperitoneal topotecan, a water-soluble camptothecin analogue, were investigated in two models of human ovarian carcinoma xenografted intraperitoneally into nude mice: the IGROV-1 tumour, which originated from an untreated patient, and the A2780 tumour, selected for
OBJECTIVE
To evaluate the feasibility and pharmacology of intraperitoneal (IP) topotecan.
METHODS
Fifteen patients with recurrent ovarian cancer in a phase I trial were treated with escalating IP topotecan doses (5-30 mg/m(2)) for pharmacokinetic analysis.
RESULTS
Dose limiting toxicity (DLT) was
OBJECTIVE
To determine the maximum tolerated dose and pharmacokinetics of topotecan when administered by the intraperitoneal route.
METHODS
A dose-escalating Phase I trial was conducted in which fifteen % of the total dose was given as an intraperitoneal bolus in two litres of D5W and the remainder
The effect of cucurbit[7]uril (CB[7]) nano-caging on the photophysical properties, particularly excited-state proton transfer (ESPT) reaction, of an eminent anti-cancer drug, topotecan (TPT), is demonstrated through steady-state and time-resolved fluorescence measurements. TPT in water (pH 6) exists
We have recently developed a liposomal nanoparticle (LNP) formulation of irinotecan based on loading method that involves formation of a complex between copper and the water soluble camptothecin. The loading methodology developed for irinotecan was evaluated to develop a LNP topotecan formulation
OBJECTIVE
Recurrent cervical cancer has traditionally been associated with a dismal prognosis. Historically, patients who developed distant metastases from cervical cancer were not considered eligible for surgical resection; only palliative treatment options are available, generally consisting of
Despite optimal surgery and appropriate first-line chemotherapy, ∼70-80 % of patients with epithelial ovarian cancer will develop disease relapse. The prognosis is poor especially for women with Platinum resistant ovarian cancer. The standard treatment for these groups of patients is The long-term survival of heavily pretreated patients with primary peritoneal cancer (PPC) is uncommon. Here, we report on a patient with PPC refractory to multiple lines of intravenous chemotherapy, namely, a combined regimen of paclitaxel and carboplatin, and single regimens of topotecan,
In this study, we report the remarkable recognition and assembly characteristics of D3h symmetric basket 16- containing two adjoining and nonpolar cavities with six biocompatible GABA residues at their northern and southern termini. From the results of
Through the high affinity of the β-cyclodextrin (β-CD) cavity for adamantane moieties, novel polysaccharide-gold nanocluster supramolecular conjugates (HACD-AuNPs) were successfully constructed from gold nanoparticles (AuNPs) bearing adamantane moieties and cyclodextrin-grafted hyaluronic acid
A previous study showed that intravenous immunoglobulin (IVIG) could preserve higher levels of biologically active lactone moieties of topotecan, 7-ethyl-10-hydroxycamptothecin (SN-38) and 10-hydroxycamptothecin at physiological pH 7.40. As one of camptothecin analogues (CPTs), the interaction of
BACKGROUND
Anti-angiogenesis therapies such as bevacizumab, the monoclonal antibody to vascular endothelial growth factor (VEGF), have been used against ovarian cancer, but transient and low peritoneal drug levels are likely a factor in treatment failure. We hypothesized that a single administration
The binding stoichiometry, binding constants, and inclusion mode of some water-soluble negatively charged cyclodextrin derivatives, i.e. heptakis-[6-deoxy-6-(3-sulfanylpropanoic acid)]-β-cyclodextrin(H1), heptakis-[6-deoxy-6-(2-sulfanylacetic acid)]-β-cyclodextrin(H2),
