Abstract: The invention relates to novel compounds which are inhibitors of the ribosome protein chaperone activity (“protein folding activity of the ribosome” or “PFAR”). More particularly, the invention relates to their use as PFAR-inhibitors, to compositions comprising them and to methods for treating proteinopathies.

Abstract: The present invention relates to novel bis-hydrazone derivatives of formula (I): wherein Ar1 and Ar2 may be identical or different and are each independently selected from the group consisting of groups of formula (II) and (III): Y1 and Z1 are independently CH or NRc+, provided that al least one of Y1 and Z1 is NRc+ and at least one of Y1 and Z1 is CH, and Ra, Rb, Rc, X2? and L as defined in the claims, or a hydrate or a solvate thereof. Compositions and kits comprising same are also described. Said bis-hydrazone derivatives of formula (I), compositions and kits are useful as drugs, in particular for treating or preventing cancers associated with the Epstein-Barr Virus.

Abstract: The invention concerns an endogenic nucleic fragment, such as an isolated retrovirus, integrated in the human DNA genome, the fragment being characterized in that it comprises, or consists of, at least part of the gag gene of an endogenetic retrovirus associated with an autoimmune disease or pregnancy failure or pregnancy pathologies, said part at least coding, directly and indirectly, for an expression product, or the complement of the fragment.
