    摘要: The present invention discloses novel cationic amphiphiles containing mannose-mimicking shikimic and quinic acid head-groups and a process for preparing cationic amphiphiles with mannose-mimicking polar head-groups such as, shikimic and quinic acids. The findings described herein also demonstrate that compounds of the present invention can target model DNA vaccines to antigen presenting cells (APCs) such as macrophages and dendritic cells (DCs), via mannose receptors expressed on the cell surface of APCs. The cationic amphiphiles disclosed herein show enhanced cellular and humoral immune response compared to their mannosyl counterpart in dendritic cell (DC, the most professional APC) based genetic immunization in mice. Cationic amphiphiles with mannose-mimicking quinic and shikic acid head-groups described in the present invention are likely to find future applications in the field of genetic immunization.

    摘要: The present invention relates to the mannose - receptor selective lysinylated cationic amphiphile and a process for preparation thereof. The compounds of the present invention can target DNA vaccines to antigen presenting cells (APCs) such as macrophages and dendritic cells (DCs), via mannose receptors expressed on the cell surface of APCs. The cationic amphiphiles disclosed herein show enhanced cellular and humoral immune response compared to their mannosyl counterparts in genetic immunization in mice. The present invention discloses that immunization with electrostatic complexes (lipoplexes) of DNA vaccines encoding melanoma antigens (gp100 and tyrosinase) and liposome of the presently described novel lysinylated cationic amphiphiles with mannose-mimicking shikimoyl head-groups provides long-lasting (100 days post melanoma tumor challenge) protective immunity in all immunized mice. Cationic amphiphiles with mannose-mimicking shikimoyl head-groups described in the present invention are likely to find future applications in the field of genetic immunization.

In addition, the present invention provides methods and compositions for knocking down the expression of a specific target gene by treating cells with the formulations comprising cationic amphiphile, a neutral colipid and a small RNA molecule. We demonstrate that our method delivers siRNA efficaciously into animal cells for the purpose of RNA interference. The area of medical science that is likely to benefit most from the present invention is RNAi therapeutics.
