The intracellular delivery of nucleic acid molecules is a complex process involving several distinct steps; among these the endosomal escape appeared to be of particular importance for an efficient protein production (or inhibition) into host cells. In the present study, a new series of ionizable vectors, derivedfromnaturallyoccurring aminoglycoside tobramycin, was prepared using improved synthetic

route to the kainoid skeleton is exemplified by the synthesis of (+/-)-kainic acid from 3-butyn-1-ol. The route relies on the aza-[2,3]-Wittigsigmatropicrearrangement to efficiently install the relative stereochemistry between C2-C3. The C4 stereocenter was derived from a diastereocontrolled iodolactonization. The aza-[2,3]-Wittigrearrangement potentially allows structural diversity at C3 and the

A highly stereoselective synthesis of (−)-kainic acid has been achieved in 14 steps and >7% overall yield starting from inexpensive trans-4-hydroxy-l-proline. The key steps are diastereoselective enolate alkylation and cuprate substitution reactions.

The present invention relates to novel aminoglycoside compounds having antimicrobial properties and being suitable, for example, as therapeutic agents for use in the treatment of mammalian disease and in particular to novel therapeutic agents suitable for use in the treatment of microbial infection in mammals. The present invention further relates to the use of pharmaceutical compositions comprising said agents in the treatment of medical conditions in mammals, in particular in the treatment of microbial infection. The agents and pharmaceutical compositions of the invention are of particular relevance in the treatment of diseases associated with antibiotic-resistant microbes. The invention further relates to compounds for use in the treatment of diseases whose treatment is made otherwise difficult due to antibiotic-class-related bacterial resistance and provides novel therapeutic agents suitable for use in the treatment of multidrug-resistant (MDR) infections.
