2-Methoxyestradiol, a natural metabolite of estradiol, exerts antiproliferative and antitumour properties in vitro and in vivo. Because of its low oral bioavailability, several promising analogues of 2-methoxyestradiol have been developed. In this study, the in vitro influence of the compound, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10)16-tetraene (C19), a(More)
2-Methoxyestradiol (2ME2) is a naturally occurring estradiol metabolite which possesses antiproliferative, antiangiogenic and antitumor properties. However, due to its limited biological accessibility, synthetic analogues have been synthesized and tested in attempt to develop drugs with improved oral bioavailability and efficacy. The aim of this study was(More)
Research into potential anticancer agents has shown that 2-methoxyestradiol exerts antiproliferative activity in vitro and in vivo in an estrogen receptor-independent manner. Due to its limited biological accessibility and rapid metabolic degradation, several new analogues have been developed in recent years. This study investigated the in vitro effects of(More)
Cancer is the second leading cause of death in South Africa. The critical role that microtubules play in cell division makes them an ideal target for the development of chemotherapeutic drugs that prevent the hyperproliferation of cancer cells. The new in silico-designed estradiol analogue 2-ethyl-3-O-sulfamoylestra-1,3,5(10)16-tetraene (ESE-16) was(More)
2-Methoxyestradiol-bis-sulphamate is a bis-sulphamoylated derivative of the naturally occurring 17-beta-estradiol metabolite namely 2-methoxyestradiol. 2-Methoxyestradiol-bis-sulphamate is regarded as a potential anticancer drug with increased antiproliferative activity when compared to 2-methoxyestradiol. The aim of this pilot in vitro study was to(More)
BACKGROUND The function of platelets have extended way beyond the horizon of haemostasis and thrombosis, and are recognised as active participants in vascular inflammation, as well as in prothrombotic complications of cardiovascular diseases. We describe and compare platelet function in type II diabetes (with and without cardiovascular manifestation) and(More)
Novel, in silico-designed anticancer compounds were synthesized in our laboratory namely, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10),15-tetraen-17-ol (ESE-15-ol) and 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10)16-tetraene (ESE-16). These compounds were designed to have improved bioavailability when compared to their source compound, 2-methoxyestradiol. This(More)
Due to their high proliferative requirements, tumorigenic cells possess altered metabolic systems whereby cells utilize higher quantities of glutamine and glucose. These altered metabolic requirements make it of interest to investigate the effects of physiological non-tumorigenic concentrations of glucose and glutamine on tumorigenic cells since deprivation(More)
Polycaprolactone (PCL) polymers which illustrate both biocompatibility and resorbability for replacement or bulking of damaged or diseased tissue are important in tissue engineering. Cytocompatibilty of these polymers was assessed on two-dimensional PCL disks and threedimensional PCL solid and PCL hollow microspheres using human uterine mixed leiomyosarcoma(More)
