Described herein is a process for the total synthesis of macrolactones and macrolactams of formula I
including E- and Z-configuration thereof, in particular, nannocystins.
A series of twenty-one L-tyrosine derivatives with modifications in the halogenation pattern of the aromatic ring and different degree of methylations on the amine and phenolic hydroxyl groups were synthesized. The structures of all the intermediates and target compounds were confirmed unambiguous by spectroscopy analysis. Additionally, all compounds were evaluated against Plasmodium falciparum and
The present invention relates to novel bicyclic and tricyclic nucleoside and nucleotide analogues as well as to oligonucleotides comprising such elements. The nucleotide analogues, LNAs (Locked Nucleoside Analogues), are able to provide valuable improvements to oligonucleotides with respect to affinity and specificity towards complementary RNA and DNA oligomers. The novel type of LNA modified oligonucleotides, as well as the LNAs as such, are useful in a wide range of diagnostic applications as well as therapeutic applications. Among these can be mentioned antisense applications, PCR applications, strand displacement oligomers, as substrates for nucleic acid polymerases, as nucleotide based drugs, etc. The present invention also relates to such applications.
