Team leader : Patricia MELNYK, PR2, Lille2 University
Patricia Melnyk graduated as an engineer in chemistry in 1989 from Ecole Nationale de Chimie de Paris. She received his Ph.D. degree in 1993 from the University of Paris VI. During the thesis she developed novel total synthesis of new indolic pentacycles as tyrosine hydroxylase inductors. She did post-doctoral training from 1993 to 1994 in Paris (ENSCP) in the group of Pr G. Jaouen in the field of bioorganometallic chemistry and from 1994 to 1996 in Lille in the group of Pr A. Tartar, in the field of combinatorial and parallel synthesis. She worked in Cerep biotech company as chemistry laboratory manager then Combinatorial Chemistry group leader. She’s working since 2002 as a chemistry professor in Lille 2 University (UL2) and created his own group in 2004. She is member of several scientific boards and of the CNU (Conseil National des Universités, section 39 and now 85). In 2007, she created with Dr André Delacourte a start-up company, AlzProtect.

The aim of our group is to design and synthesize candidate-drug in the field of neurodegenerative (Alzheimer’s disease), neurologic and parasitic (Malaria) diseases. We are combining structurally based rational design and parallel synthesis of focused libraries. During the last years, in accordance with the general axis of the unit, we have started a program based on the design of c-Met inhibitors and their vectorisation. In parallel, H. Drobecq conducts a plateform of mass spectrometry – biomolecules analysis. He is thus engaged in a lot of research projects with national and international collaborations and is co-author of the publications.
New antimalarial compounds (collaboration Pr P. Grellier, EA3335, MNHN, Paris)
Chloroquine (CQ) was a mainstream drug in the fight against Plasmodium falciparum, but its efficacy is eroded by the emergence of resistant parasites. We have developed compounds able to accumulate into the food vacuole of the parasite, inhibit the heme polymerisation more efficiently than CQ. These compounds showed better antimalarial properties in vitro and in some cases in vivo. In all series, 1,4-bis(3-aminopropyl)piperazine linker provided better activity upon CQ-resistant strain.

Several series of amodiaquine analogs, devoided of the 4’-phenol substituent, which seem responsible of the toxicity, were synthesized and brought a new light on the SAR of the 4-anilinoquinolines family. We also designed and analysed amodiaquine and amopyroquine analogs, bearing new functionalities in 4’-position : amine, alkyle and aryle groups thanks to a Suzuki reaction and obtained two potent compounds.

In parallel, we also explored other type of compounds, leading to the synthesis of the glyoxylhydrazone type library of 80 compounds and focused library of iron chelating acylhydrazones from salicylic aldehyde.

Sigma-1 ligands as neuroprotective agents (collaborations Dr T. Maurice, Inserm U710 Montpellier ; Pr C. Vaccher, EA4034 Lille ; Pr R. Bordet, EA1046 Lille)
Sigma-1 protein and its effectors, endogeneous agonists or antagonists, are implicated in physiological desadaptions leading to addiction. Previously we showed the affinity of 1,2,3,4-tetrahydroisoquinoline-hydantoine (Tic-hydantoïne) mixed structure for σ 1 receptors. We have continued this research program working on the synthesic methodologies, TicHyd structure or amino side-chain.

Nanomolar, selective and non toxic agonists have shown a high potential for cocaine weaning and are under development.
C-Met inhibitors as anticancer agents (collaborations Dr V. Fafeur, UMR8161, Lille)
In collaboration with other teams in IBL, our aim is to design and synthesize inhibitors of c-Met tyrosine kinase activity and vectorise them specifically to cancer cells thanks to lipid nanoparticules decorated with functionalised dextrans. Depending on their functionalised level, these polymers could selectively interact with protein with bearing heparin binding domain, such as c-Met and HGF/SF. This was demonstrated in the case of PDGF-BB growth factor, and confirmed in the lab using polysaccharide microarrays. A new and controlled method of dextran lipidation allowing the preparation of grafted nanoparticules was developed. In parallel, the design of intracellular inhibitors combined both pharmacomodulation of published c-Met inhibitors and chemoinformatic search for new pharmacophores.
Anti Alzheimer compounds (collaborations Dr A. Delacourte, Inserm U837 Lille ; AlzProtect ; Pr C. Vaccher and Pr P. Odou, EA4034 Lille)
Alzheimer’s disease (AD) is a frequent neurodegenerative disorder in the aged population, provoking the complete loss of cognitive functions and dementia. There is no cure and symptomatic treatments available have marginal effects on patients and on the evolution of the disease. APP protein is in the heart of AD. One of its metabolites, the neurotoxic Aβ peptide, aggregates to form amyloid plaques according to the amyloidogenic pathway. The other competing way, the neurotrophic pathway, prevents the formation of Aβ peptide and provides APP fragments with neurotrophic and important neurophysiological functions: sAPPalpha and AICD.

Their absence could stimulate Tau pathology, degenerating process frequently encountered during aging and leading to AD.
Results obtained by A. Delacourte et al. from a human brain library showed that sAPPalpha and AICD decreased during AD. In a same way, familial forms of AD rely more on AICD decrease than Aβ modifications. All recent publications underlign the importance of APP loss of function in AD.
We have started a program aiming on slowing the degradation of important APP fragments by the endosome-lysosome system. We take advantage of our expertise of antimalarial compounds and chloroquine analogs. This last compound accumulates into the acidic food vacuole of the parasite and inhibits heme polymerisation. A library of several hundred of compounds was available in the lab and was screened on a cellular test. Hits were optimized and a new family of compounds (named MSBD) was patented (WO 2006 051489). Most potent derivatives increase APP-CTF alpha and AICD fragment 10 times, leading to a parallel decrease in Aβ secretion of 80%.
Our lead compound crosses the BBB, shows no toxicity on mouse model, no cardio or geno- toxicity and provides an interesting ADME-Tox profile. This project is funding by an “Aide au Transfert” Oseo grant.
In a parallel way, we have explored structurally different compounds with potent pharmacophores and good theorical physicochemical properties. We have thus identified and developed a new family which is under patenting. This project is funding by an ANR grant.
AlzProtect, a start-up company, was created to develop these compounds through preclinical and clinical phases. Our company was laureate of the “Concours national d’aide à la création d’entreprises innovantes” in 2007.
