An efficient catalytic one-pot synthesis of TBDMS-protected diacylglycerols has been developed, starting from enantiopure glycidol. Subsequent migration-free deprotection leads to stereo- and regiochemically pure diacylglycerols. This novel strategy has been applied to the synthesis of a major Mycobacterium tuberculosis phospholipid, its desmethyl analogue, and platelet activating factor.

The present invention relates to novel synthetic analogues of phosphatidyl-myo-inositol mannosides (hereinafter referred to as PIMs) of general formula (I): or a pharmaceutically acceptable salt thereof, to the method for preparing same and to the use thereof in the prevention or treatment of a disease associated with the overexpression of cytokines or of chemokines, in particular of TNF and/or of IL-12. The invention also relates to a pharmaceutical composition comprising at least one synthetic derivative of PIM.
The glycosylation of unprotected carbohydrates has emerged as an area of significant interest because it obviates the need for long reaction sequences involving protecting-group manipulations. Herein, we report the one-pot synthesis of anomeric glycosyl phosphates through the condensation of unprotected carbohydrates with phospholipid derivatives while retaining high stereo- and regioselective control

The present invention relates to extracting multiple types of compounds or synthetic compounds capable of promoting nucleic acid delivery from a traditional Chinese medicine, promoting the absorption of a nucleic acid such as sRNA and the entry thereof into a target cell by using the extracted compounds or multiple combinations, and promoting the entry of the nucleic acid into a target site in an object body having such a need. The traditional Chinese medicine is selected from traditional Chinese medicine decoction pieces derived from Rhodiola rosea, Herba Taraxaci, Herba andrographitis, and Flos Lonicerae. The nucleic acid is used for treating diseases, such as heart, spleen, kidney, stomach, lung and/or bowel diseases.
