چکیده انگلیسی
Phosphoantigens enable the access to a new anti-tumoral and anti-infectious therapeutic pathway, based on innate immunity through the selective activation of Tγ9δ2 lymphocytes. The first proof of concept of this new immunotherapy approach was demonstrated with the synthetic phosphoantigen named bromohydrin pyrophosphate (BrHPP, IPH 1101) which was administrated in racemic form to about 200 patients in six clinical trials with good safety and promising early signals of efficacy in type C viral hepatitis and follicular non-Hodgkin's lymphoma. Enantiopure samples of BrHPP in gram scale are required for further studies on structure-bioactivity relationship. Thus we developed two complementary synthetic pathways, the first using transformation of a chiral compound and the second involving asymmetric synthesis starting from a prochiral building-block. The synthesis of a second-generation phosphoantigen, N-HDMAPP, which bears a phosphoramidate moiety, was also investigated.
