    Abstract: Se describen novedosos fármacos anti-influenza bi-funcionales, de doble enfoque, formados mediante conjugación con agentes anti-inflamatorios. Fármacos ejemplares de acuerdo con la invención incluyen conjugados de zanamivir (ZA) que porta ácido cafeico (CA) ZA-7-CA (1), ZA-7-CA-amida (7) y ZA-7-Nap (43) para inhibición simultánea de neuraminidasa de virus de influenza y supresión de citosinas proinflamatorias. Se proporcionan métodos sintéticos para la preparación de estos fármacos conjugados anti-influenza mejorados. Los conjugados de ZA bifuncionales sintéticos actúan sinérgicamente hacia la protección de ratones infectados letalmente por virus de influenza H1N1 o H5N1. La eficacia de conjugados ZA-7-CA, ZA-7-CA-amida y ZA-7-Nap es mucho mayor que la terapia de combinación de ZA con agentes anti-inflamatorios.

    Abstract: Immunogenic compositions, cancer vaccines and methods for treating cancer are provided. Compositions compris-ing: (a) a glycan such as Globo H or an immunogenic fragment thereof, wherein the glycan is conjugated with a carrier protein by a linker such as para-nitrophenyl; and (b) an adjuvant comprising glycolipid capable of binding CDId on a dendritic cell, such as an a-galactosyl-ceramide derivative, wherein the immunogenic composition induces an immune response that induces a higher relative level of IgG isotype antibodies as compared to IgM isotype antibodies, are provided. Immunogenic compositions compris-ing the carrier protein diphtheria toxin cross-reacting material 197 (DT-CRM 197) and the adjuvant C34 are provided. Antibodies generated by immunogenic compositions disclosed herein further neutralize at least one of the antigens Globo H, stage-specific embryonic antigen-3 (SSEA-3) and stage-specific embryonic antigen-4 (SSEA-4). Therapeutics against breast cancer stem cells comprising immunogenic compositions comprising Globo H, SSEA-3 or SSEA-4 conjugated with DT-CRM 197.

    Abstract: Glycosphingolipids (GSLs) bearing α-glucose (α-Glc) that preferentially stimulate human invariant NKT (iNKT) cells are provided. GSLs with α-glucose (α-Glc) that exhibit stronger induction in humans (but weaker in mice) of cytokines and chemokines and expansion and/or activation of immune cells than those with α-galactose (α-Gal) are disclosed. GSLs bearing α-glucose (α-Glc) and derivatives of α-Glc with F at the 4 and/or 6 positions are provided. Methods for iNKT-independent induction of chemokines by the GSL with α-Glc and derivatives thereof are disclosed. Methods for immune stimulation in humans using GSLs with α-Glc and derivatives thereof are provided.

    Abstract: Methods are provided for suppressing cancer metastasis. Cancer metastasis is the most common cause of treatment failure and death in cancer patients. Tumor cell invasion and/or migration can be significantly inhibited after fibrillar proteins (rVP1, F-HSA, and F-BSA) treatment in vitro. In addition, rVP1 can significantly suppress murine and human breast cancer metastasis and human prostate and ovarian cancer metastasis in vivo while F-HSA can significantly suppress murine breast cancer metastasis. Compositions of fibrillar proteins as anti-cancer metastasis therapeutics and methods of use thereof are provided herein.
