Abstract
Introduction With the aim of repositioning commercially available drugs for the inhibition of the anti-apoptotic myeloid cell leukemia protein, Mcl-1, implied in various cancers, five molecules, highlighted from a published theoretical screening, were selected to experimentally validate their affinity toward Mcl-1. Results A detailed NMR study revealed that only two of the five tested drugs, Torsemide and Deferasirox, interacted with Mcl-1. NMR data analysis allowed the complete characterization of the binding mode of both drugs to Mcl-1, including the estimation of their affinity for Mcl-1. Biological assays evidenced that the biological activity of Torsemide was lower as compared to the Deferasirox, which was able to efficiently and selectively inhibit the anti-apoptotic activity of Mcl-1. Finally, docking and molecular dynamics led to a 3D model for the Deferasirox:Mcl-1 complex and revealed the positioning of the drug in the Mcl-1 P2/P3 pockets as well as almost all synthetic Mcl-1 inhibitors. Interestingly, contrary to known synthetic Mcl-1 inhibitors which interact through Arg263, Deferasirox, establishes a salt bridge with Lys234. Conclusion Deferasirox could be a potential candidate for drug repositioning as Mcl-1 inhibitor.

Abstract
In the area of cancer research, the development of new and potent inhibitors of anti-apoptotic proteins is a very active and promising topic. The small molecule MIM1 has been reported earlier as one of the first selective inhibitors of the anti-apoptotic protein Mcl-1. In the present paper, we first revised the structure of this molecule based on extensive physicochemical analyses. Then we designed and synthesized a focused library of analogues for the corrected structure of MIM1. Next, these molecules were subjected to a panel of in cellulo biological studies, allowing the identification of dual Bcl-xL/Mcl-1 inhibitors, as well as selective Mcl-1 inhibitors. These results have been complemented by fluorescence polarization assays with the Mcl-1 protein. Preliminary structure-activity relationships were discussed and extensive molecular modelling studies allowed us to propose a rationale for the biological activity of this series of new inhibitors, in particular for the selectivity of inhibition of Mcl-1 versus Bcl-xL.

Abstract
Alzheimer's Disease (AD) is a neurodegenerative brain disorder in which many biological dysfunctions are involved. Among them, two main types of lesions were discovered and widely studied: the amyloid plaques and the neurofibrillary tangles (NFTs). These two lesions are caused by the dysfunction and the accumulation of two proteins which are, respectively, the beta-amyloid peptide and the tau protein. The process that leads these two proteins to aggregate is complex and is the subject of current studies. After a brief description of the aggregation mechanisms, we will provide an overview of new therapeutic agents targeting the different dysfunctions and toxic species found during aggregation.

Abstract
This work describes the study of the mechanism of action and spectrum of activity of MR22388, a novel anti-cancer agent belonging to the tripentone series. MR22388 is highly cytotoxic (within the nanomolar range) against numerous cancer cell lines and studies of its cytotoxicity mechanisms show that it is a weak inhibitor of the polymerization of tubulin and that it induces apoptosis via the MAP kinase pathways. Further MR22388 is a very strong inhibitor of several kinases including the tyrosine kinase FLT3-ITD. FLT3-ITD is a mutated form of the tyrosine kinase receptor (RTK) FLT3, resulting in the constitutive activation of the kinase, occurring in about 25% of normal karyotypes' Acute Myeloid Leukemia (AML) and is linked to a bad prognosis. Consecutively, MR22388 appears as a novel promising anticancer lead agent especially for AML therapy.

Abstract
The Raman and ir spectra of a murine IgG2a monoclonal antibody molecule are reported. In accordance with previous studies on immunoglobulins, the secondary structure is predominantly of the beta-sheet type. The low frequency region of the Raman spectrum was also analyzed in detail. A structured band with two maxima near 43 and 94 cm(-1) was observed. This band has been attributed to vibrations of elastic body. The results are interpreted using a simple elastic model.

Abstract
We report nine cases of haemophagocytic syndrome (HS) in patients with human immunodeficiency virus infection, and review the 17 cases described to date in the literature. In 21 of 26 cases, HS developed during an advanced stage of immunodeficiency. Clinical and haematological signs are not specific in this setting, and the diagnosis relies on histological features, mainly bone marrow examination. An opportunistic infection was associated in three cases and a lymphoid malignancy in two of our nine cases. The role of the human immunodeficiency virus in the occurrence of the HS remains to be defined. The overall prognosis is poor as six of our nine patients died within 12 months of presentation.

Abstract
The toxic effects of daunorubicin with specific reference to acute, subacute, and long-term studies in animals are reviewed, and its clinical toxicity is considered. We emphasize the importance of hematologic toxicity and infections when treating with daunorubicin. A summary of the work done on detoxifying activities of certain compounds is presented, and the activities that increase the toxic effects of daunorubicin are discussed. Finally, the immunosuppressive, mutagenic, teratogenic, and carcinogenic activities of daunorubicin are mentioned.
