  • Publication number: 20230218652
    Abstract: The invention relates to an antifungal prodrug which comprises an antifungal moiety which is linked to a trigger moiety by means of a self-immolative spacer. The trigger moiety is selected from glycosyl residues and oligosaccharides, stabilizes the self-immolative spacer and is cleavable by a pathogen hydrolytic enzyme which is preferably an extracellular glycosidase (EC 3.2.1). When the trigger moiety is cleaved by the pathogen hydrolytic enzyme, the self-immolative spacer undergoes a spontaneous degradation so as to release the antifungal moiety. The invention also relates to pharmaceutical compositions comprising said prodrug and to its use in the treatment of infectious diseases.

  • Publication number: 20230088717
    Abstract: The present invention relates to a new family of iNKT stimulators, referred to as 6?-O-PEGm-NHR-GalCer, which are potent analogues of KRN7000. These iNKT stimulators can advantageously be used in therapy, in particular for the prevention and/or treatment of many diseases requiring a stimulation of an immune response, such as cancer, viral, bacterial or parasitic diseases, autoimmune diseases or inflammatory diseases. The iNKT cell stimulator of the invention may be coupled to a biological carrier, such as a therapeutic and/or targeting agent, or be vectorized, for example in nanoparticles, to be specifically delivered to target cells.

  • Patent number: 4500962
    Abstract: A computer system utilizing an N bit word in which a directly addressable space is limited to 2.sup.N-1 words or 2.sup.N characters by the system architecture.
