manuscript, we report the synthesis and X-ray characterization of three N6-aminoacid/peptide–adenine-derivatives; the zwitterion N6GlyAde·0.5H2O (1), its corresponding protonated form N6GlyAde·2HCl·H2O (2) and N6GlyGlyAde·H2O (3). In the zwitterion complex (1), the adenine is protonated at N(3) and the anionic carboxylate interacts with the imidazole ring of the neighbouring purine molecule. It also interacts

New conjugates of purine and 2-aminopurine with several α- and ω-amino acids have been synthesized following two approaches based on the condensation and nucleophilic substitution reactions. The enantiomeric purity of the isolated compounds has been confirmed by reversed-phase HPLC using a chiral stationary phase to demonstrate the absence of racemization during the synthesis. The conjugates are inactive

The subject invention pertains to a method of determining methylation state and chromatin structure of target loci. The method comprises treating the genetic material obtained from the cells with DNA methyltransferase, capturing target genetic loci using a set of oligonucleotides, ligating the target loci with oligonucleotide patches that flank the target loci, treating the target loci flanked by oligonucleotide patches with bisulfite, optionally amplifying the target loci by polymerase chain reaction, sequencing the PCR products, and analyzing the sequences to determine methylation state and chromatin structure of the target loci. The current invention also provides a method to identify genes associated with a disease. The invention also provides a method to detect cells suffering from a disease in a group of cells. The current invention also provides kits suitable for carrying out the method of determining methylation state and chromatin structure of the target loci.

Novel purin-6-yl, 2-aminopurin-6-yl and N-(purin-6-yl)glycyl derivatives of (S)-lysine and (S)-ornithine with free alpha-functional groups, as well as compounds containing N-9-(2-hydroxy-ethoxy)methyl substituent in the purine core have been synthesized and tested for their inhibitory effect against Mycobacterium tuberculosis strains. Among the synthesized conjugates, one compound exhibiting a significant level of antimycobacterial activity has been found.
