Abstract:

L'électrochimiothérapie est un traitement anticancéreux utilisé en routine en Europe dans près de 130 centres de traitement du cancer. Le taux de réponse objective atteint 85 % pour le traitment de tumeurs cutanées et sous-cutanées et des études sont en cours afin d'appliquer ce traitement à des tumeurs profondes. Au cours de ce doctorat, les méchanismes sous-jacents à cette excellente efficacité antitumorale ont été étudiés. Dans un premier temps, l'objectif a été d'évaluer la capacité de l'électrochimiothérapie à induire la mort des cellules souches cancéreuses, considérées comme les racines

Abstract:

Since the discovery of anti-tumor activity of cisplatin in 1960, significant progress has been made in treating metastatic or advanced cancer with cisplatin and platinum compounds. Platinum compounds covalently bind to DNA and disrupt DNA function. They are also known to bind with amino acids like methionine, histidine and cysteine to form cisplatin-protein adducts which are responsible for most of its cytotoxicity and side effects. Recent articles on cisplatin-protein have shown that adding bulky adjuncts to cisplatin or using different platinum compounds varies the degree and extent of react

Abstract:

Epigenetic transcriptional gene silencing plays a fundamental role in cancer development and has been considered as a target for cancer therapy in the last few years, mainly due to its reversibility by small molecules. Among the several methylated genes investigated, glutathione-S-transferase CGST) PI, a protein belonging to cellular detoxification systems, has been shown to be extensively promoter-methylated in prostate cancer. My study therefore describes a new therapeutic approach against prostate cancer, based on the combination of demethylating agents and brostallicin, a DNA minor groove

Abstract:

Modifications of the potent anticancer agent taxol were carried out in order to gain an understanding of the chemical reactivity of the drug and the factors which contribute to its biological activity. The C-2' and/or the C-7 hydroxyl groups of taxol were substituted with acetyl, ßalanyl, silyl, succinyl, trichloroethyloxycarbonyl or carbonate linked dibenzylidene protected glucosyl groups. The C-7 position was selectively epimerized under free radical conditions and a 2'-epiacetyltaxol was produced via base catalysed epimerization.

Abstract:

The mechanism of resistance of tumor cells to chemotherapeutic agents is explored using probabilistic methods where it is assumed that resistant cells arise spontaneously with a defined frequency. The resistance process is embedded in a discrete time Markov branching process which models the growth of the tumor and contains three seperate cell types: stem, transitional and end cells. Using the asymptotic properties of such models it is shown that the proportion of each type of cell converge to constants almost surely. It is shown that the parameters relating to stem cell behaviour determine th

On the basis of clinical studies, some researchers have advocated that the neurohormone and antioxidant melatonin, shown to possess intrinsic anticancer properties, be used as co-therapy in cancer patients being treated with the antineoplastic agent 5-fluorouracil, as increased patient survival times and enhanced quality of life have been observed. The focus of this research was thus to investigate the mechanisms of this seemingly beneficial drug interaction between 5-fluorouracil and melatonin.

The problem of finding targeted medicine is a central problem in chemotherapy. From this point of view the ubiquitin-proteasome system is a highly promising object in the pharmaceutical approach. Proteasome plays a critical role in cellular protein degradation, cell cycle and apoptosis regulation. Proteasome inhibitors are substances blocking the actions of proteasome. Cancer cells are more sensitive to inhibition of the ubiquitin-proteasome system than normal cells. Therefore proteasome inhibitors have the potential to be successfully used in the cancer treatment.

Pancreatic cancer is known to be one of the most life-threatening cancers characterized by aggressive local invasion and distant metastasis. The high basal level of autophagy in pancreatic cancer may be responsible for the low chemotherapeutic drug response rate and poor disease prognosis.

Hence, oncologists begin to consider the tumor microenvironment when exploring new drug targets. In the present study, the anti-tumorigenic mechanisms of two major

Abstract:

碩士<br>嘉南藥理大學<br>生物科技系<br>103<br>Hepatocellular carcinoma (HCC) is the third most common malignancy worldwide. More than 75% of HCC cases occur in the Asia-Pacific region. In Taiwan, there are about 3,700 patients a year die from liver cancer. There are many chemical drugs have been used in liver cancer therapy. Antrodia cinnamomea is a medicinal fungus that has been served as a functional food in Taiwan for decades. Previous studies have shown that the secondary metabolites form Antrodia cinnamomea have various activities such as antitumor, protection of liver function, anti-inflammation and a

Abstract:

The thesis “Ancillary Ligand Effects on the Anticancer Activity of Ruthenium (II) Piano Stool Complexes” is an effort to design better antitumor metallodrugs based on ruthenium(II) complexes with various H-bond donor/acceptor ligands and to understand their mechanism of action. Chapter 1 presents a brief review of metallodrugs and their mechanism of action. Different classes of metallodrugs are discussed. A short discussion on ruthenium based anticancer drugs and their established mechanism of action is also included in this chapter. Chapter 2 deals with the synthesis, characterization and a

Les glycosides cardiotoniques sont des inhibiteurs des pompes sodium / potassium utilisés pour le traitements des insuffisances cardiaques, qui détiennent également des activités anticancéreuses et épigénétiques récemment caractérisées. Toutefois, dans l’objectif de repositionner ces médicaments comme traitement anticancéreux, les mécanismes sousjacents aux activités anticancéreuses et épigénétiques des glycosides cardiotoniques restent à être déterminés. Dans nos travaux, nous révélons que la proscillaridine A est le glycoside cardiotonique qui détient des activités anticancéreuses et é

As with liver cancer, a large majority (around 85%) of the global burden occurs in the less developed regions, where it accounts for almost 12% of all female cancers. About 90% of cervical cases are associated with human papillomavirus (HPV) as a causative agent and this virus is frequently transmitted through sexual contact involving exchange of fluids (Walboomers et al.

Abstract:

Anticancer active metal complexes such as cisplatin are routinely used for treating various cancers since 1978. However, the side effects of cisplatin overwhelm its therapeutic potential, especially in the latter stages of treatment. The nonspecific cytotoxicity of drugs could be avoided if targeted delivery to cancer cells is achieved using two different methodologies namely, enhanced permeability and retention in solid tumors (EPR) and receptor mediated endocytosis using a homing agent (RME).

Abstract:

The present thesis deals with different aspects of the chemistry of oxovanadium(IV) complexes, their interaction with double stranded DNA, photo-induced DNA cleavage, photo-enhanced cytotoxicity in visible light and red light and localisation and cellular uptake to understand the mechanism of cell death. Chapter I presents a general introduction on potential of transition metal complexes as photochemotherapeutic agents. A brief introduction about Photodynamic Therapy (PDT) as a new alternative to chemotherapy for treating cancer has been made. Various modes of interaction of small molecules
