This study has involved the design, synthesis and evaluation of novel HIV-1 enzyme inhibitors accessed by synthetic elaboration of Baylis-Hillman adducts. Several series of complex coumarin-AZT and cinnamate ester-AZT conjugates have been prepared, in high yields, by exploiting the click reaction between appropriate Baylis-Hillman derived precursors and azidothymidine (AZT), all of which have been fully characterised using spectroscopic techniques. These conjugates, designed as potential dual-action HIV-1 inhibitors, were tested against the appropriate HIV-1 enzymes, i.e. HIV-1 reverse transcr

The development of effective methods to cryopreserve precious cell types has had tremendous impact on regenerative and transfusion medicine.

The aminoacyl-tRNA synthetases are a family of enzymes involved in the process of translation, more specifically, ligating amino acids to their cognate tRNA molecules. Recent evidence suggests that aminoacyl-tRNA synthetases are capable of aminoacylating proteins, some of which are involved in the autophagy pathway. Here, we test the conditions under which E. coli and human threonyl-tRNA synthetases, as well as hisidyl-tRNA synthetase aminoacylate themselves. These reactions are ATP dependent, stimulated by Mg2+, and are inhibited by increasing cognate tRNA concentrations. These data represent

Hypoxia Inducible Factors (HIF) functions are master regulators of oxygen homeostasis and have a key role in the physiological responses to hypoxia including angiogenesis and erythropoiesis. Under hypoxia, levels of HIF-α subunits increase, they hetereodimerise with HIF-1β sub unit and promote the initiation of transcription of target genes. Under normoxia, oxygen dependent HIF-α degradation is promoted by hydroxylation of either of two proline residues (Pro402 and Pro564).

The net result is the formation of long, homopolymeric chains, the exact purpose of which is not clearly understood.

Ce manuscrit de thèse présente le développement de méthodes basées sur la spectrométrie de masse consacrées à la recherche d'inhibiteurs d'enzymes en milieux complexes, tels que les extraits de plantes. L’enzyme Tyrosinase a été utilisé comme principale cible biologique du fait de son implication dans les processus d’hyperpigmentation cutanée. De ce fait, la recherche d’inhibiteurs de cette enzyme, présente un grand intérêt pour l'industrie cosmétique. La première partie de ce manuscrit décrit la mise en place de la chromatographie d'affinité frontale (FAC), permettant d’obtenir le classement

Streszczenie:

The present thesis investigates targeted (locally and systemically) delivery of a novel group of inhibitors of enzyme transglutaminases (TGs). TGs are a widely distributed group of enzymes that catalyse the formation of isopeptide bonds between the y-carboxamide group of protein-bound glutamines and the a-amino group of protein-bound lysines or polyamines. The first group of the novel inhibitors tested were the tluorescently labelled inhibitors of Factor XIIIa (FXIIIa). These small, non-toxic inhibitors have the potential to prevent stabilisation of thrombi by FXIIIa and consequently increase

Streszczenie:

A high proportion of prostate cancers have been shown to be androgen-dependent. The biosynthesis of the androgens is catalysed by the cytochrome P450 enzyme 17[alpha]-hydroxylase/17, 20-lyase (P450[sub]17[alpha]), which is responsible for the conversion of C[sub]21 steroids (for example pregnenolone and progesterone) to the androgens (for example dehydroepiandrosterone and androstenedione respectively). The inhibition of this enzyme would therefore lead to the overall reduction in the level of androgens and thus result in an overall decrease in the stimulation of androgen-dependent cancer cell

Streszczenie:

Alzheimer’s disease (AD) is the most common form of dementia and one of the most important health-care problems in the world, due to its high prevalence and unaffordable personal and economic impact. Moreover, current commercialised treatments are only symptomatic, but are not capable of preventing, curing or even delaying the disease progression. Because AD arises from a complex network of pathological events, such as dysfunction in neurotransmitter systems (mainly cholinergic and glutamatergic), β-amyloid and tau proteins disorders, oxidative stress or neuroinflammation, amongst others, the

Aphids feed strictly on the nutritionally poor diet of phloem sap by piercing-sucking mouthparts, and thus maintain an obligate endosymbiotic association with Buchnera aphidicola, a member of the class -Proteobacteria closely related to Escherichia coli. It is commonly accepted that Buchnera provides essential nutrients to aphids. The enzyme prephenate dehydratase (PDT) is encoded by pheA, and is a terminal and committed enzyme in the biosynthesis of L-Phe in the shikimate pathway.

It is found in almost all animal cell types and is involved in cellular responses to stimuli such as stress, ultraviolet irradiation, and bacterial or viral antigens. NF-κB plays a key role in regulating the immune response to infection. Consistent with this role, incorrect regulation of NF-κB has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection, and improper immune development. Therefore, we report selective inhibitor of NF-κB activation expected wa

Streszczenie:

Angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I (Ang I) to angiotensin II (AngII). ACE also cleaves the terminal dipeptide of vasodilating hormone bradykinin (a nonapeptide) to its inactive form. Therefore, inhibition of ACE is one of the treatments of hypertension. A number of ACE inhibitory antihypertensive drugs are known. ‘Oxidative stress’ is another disease state caused by an imbalance in the production of oxidants and antioxidants in the body. A number of studies suggest that hypertension and oxidative stress are interdependent. Therefore, ACE inhibitors ha
