Cancer is the second most common cause of death in the USA. Among the known classes of anticancer agents, the microtubule-targeted antimitotic drugs are considered to be one of the most important. They are usually classified into microtubule-destabilizing (e.g., Vinca alkaloids) and microtubule-stabilizing (e.g., paclitaxel) agents. Combretastatin A4 (CA-4), which is a natural stilbene isolated...

Abstract. – OBJECTIVE: Withaferin-A (WF-A) is a well-known dietary compound isolated from Withania somnifera. It has marked pharmacological potential and has been shown to exhibit antiproliferative activity against several types of cancerous cells. Currently, the main focus of anti-cancer therapeutic development is to identify apoptosis-inducing drug-like molecules. Osteosarcoma is a rare type ...

BN80927 belongs to a novel family of camptothecin analogs, the homocamptothecins, developed on the concept of topoisomerase I (Topo I) inhibition and characterized by a stable seven-membered -hydroxylactone ring. Preclinical data reported here show that BN80927 retains Topo I poisoning activity in cell-free assay (DNA relaxation) as well as in living cells, in which in vivo complexes of topoiso...

Several lines of evidence suggest that nonsteroidal antiinflammatory drugs may be effective in preventing colorectal cancer. These include animal experiments, case-control studies, and clinical experience with sulindac in promoting the regression of adenomatous colon polyps in adenomatous polyposis coli. We determined the antiproliferative activity of various nonsteroidal antiinflammatory drugs...

The aim of the study was to isolate and identify the major cytotoxic principle from plant leaves of Pogostemon quadrifolius (Benth.) and evaluate its antiproliferative potential against human cancer cells. Plant leaves were extracted sequentially with a soxhlet apparatus, using petroleum ether, chloroform and methanol solvents. Petroleum ether and chloroform extracts exhibited antiproliferative...

BACKGROUND Gossypol, a natural polyphenolic compound present in cottonseeds, possesses antiproliferative and pro-apoptotic effects in in vivo and in vitro models. There are two enantiomers, (+)-gossypol and (-)-gossypol, the latter being a more potent inhibitor of cancer cell growth. Here, the effect of bovine serum albumin (BSA) and dextran-coated charcoal-treated fetal bovine serum (DCC-FBS)-...

agent technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations due to its capability to automatically modify themselves in response to changes in their operating environment. multi agent system (mas) approach is the construction of a complex system as a se...

The potential antitumor activity of cannabinoid receptor agonists, such as the aminoalklylindole WIN55,212-2 (WIN2), has been studied extensively, but their potential interaction with conventional cancer therapies, such as radiation, remains unknown. In the present work, the influence of WIN2 on the antiproliferative activity of radiation in human (MCF-7 and MDA-MB231) and murine (4T1) breast c...

One of the world’s main causes cancer-related fatalities worldwide is colorectal cancer. The adherent epithelial cells known as HCT116 (human carcinoma) are frequently employed to examine inflammatory responses in colonic cells. They derived from human cancer cell line. Crocin, a potent antioxidant, anticarcinogenic was tested this study see how it affected HCT-116 MTT analysis used assess viab...

Abstract A novel series of complexes with the formula [MLCl] [M = Co(II) (1), Ni(II) (2), Cu(II) (3), Zn(II) (4)] arising from Pyridyl ligand, N,N′-bis(1-(2-pyridyl)ethylidene)-2,2-dimethylpropane-1,3-diamine), L, was synthesized and investigated by elemental analyses, FT-IR, 1 H 13 C NMR, Powder XRD, thermal analyses. TGA analysis indicated that all degraded in three different steps, while PXR...
