This invention relates to processes that amplify, in a polymerase chain reaction architecture, oligonucleotide analogs that incorporate non-standard nucleobase analogs from an artificially expanded genetic information system. These pair in DNA duplexes via patterns of hydrogen bonds that are different from patterns that join the thymine-adenine and guanine-cytosine nucleobase pairs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 686747-51-3, you can also check out more blogs about686747-51-3

This invention covers methods for isothermal amplification of DNA, based on the unexpected discovery that primers having, at some positions, adenine substituted by 2-aminopurine or diaminopurine, guanine substituted by inosine, thymine substituted by 2-thiothymine, and cytosine substituted by N4-ethylcytosine are accepted by enzymes used in standard recombinase polymerase assays (RPA). Further unexpected was the discovery that target nucleotides are efficiently amplified in an RPA-like process (hereinafter abbreviated as simply RPA) using substituted primers. The invention also covers RPA-like processes that use substituted primers tagged with oligonucleotides incorporating nucleotides from artificially expanded genetic information systems (AEGIS).

7-Deazapurines are known to possess broad antiviral activity, however the 2?-C-methylguanosine analogue displays poor cell permeation and limited phosphorylation, thus is not an efficient inhibitor of hepatitis C virus (HCV) replication. We previously reported the 6-O-methyl entity as a prodrug moiety to increase liphophilicity of guanine nucleosides and the ProTide approach applied to 2?-C-methyl-6-O-methylguanosine has lead to potent HCV inhibitors now in clinical trials. In this Letter, we report the synthesis and biological evaluation of 2?-C-methyl-6-O-methyl-7-deaza guanosine and ProTide derivatives. In contrast to prior studies, removal of the N-7 of the nucleobase entirely negates anti-HCV activity compared to the 2?-C-methyl-6-O- methylguanosine analogues. To understand better this significant loss of activity, enzymatic assays and molecular modeling were carried out and suggested 2?-C-methyl-6-O-methyl-7-deaza guanosine and related ProTides do not act as efficient prodrugs of the free nucleotide, in marked contrast to the case of the parent guanine analogue.

Current treatment of toxoplasmosis targets the parasite?s folate metabolism through inhibition of dihydrofolate reductase (DHFR). The most widely used DHFR antagonist, pyrimethamine, was introduced over 60 years ago and is associated with toxicity that can be largely attributed to a similar affinity for parasite and human DHFR. Computational analysis of biochemical differences between Toxoplasma gondii and human DHFR enabled the design of inhibitors with both improved potency and selectivity. The approach described herein yielded TRC-19, a promising lead with an IC50 of 9 nM and 89-fold selectivity in favor of Toxoplasma gondii DHFR, as well as crystallographic data to substantiate in silico methodology. Overall, 50% of synthesized in silico designs met hit threshold criteria of IC50 < 10 muM and >2-fold selectivity favoring Toxoplasma gondii, further demonstrating the efficiency of our structure-based drug design approach.

7-Deazaguanine modifications protect phage DNA from host restriction systems

Genome modifications are central components of the continuous arms race between viruses and their hosts. The archaeosine base (G+), which was thought to be found only in archaeal tRNAs, was recently detected in genomic DNA of Enterobacteria phage 9g and was proposed to protect phage DNA from a wide variety of restriction enzymes. In this study, we identify three additional 2?-deoxy-7-deazaguanine modifications, which are all intermediates of the same pathway, in viruses: 2?-deoxy-7-amido-7-deazaguanine (dADG), 2?-deoxy-7-cyano-7-deazaguanine (dPreQ0) and 2?-deoxy-7- aminomethyl-7-deazaguanine (dPreQ1). We identify 180 phages or archaeal viruses that encode at least one of the enzymes of this pathway with an overrepresentation (60%) of viruses potentially infecting pathogenic microbial hosts. Genetic studies with the Escherichia phage CAjan show that DpdA is essential to insert the 7-deazaguanine base in phage genomic DNA and that 2?-deoxy-7-deazaguanine modifications protect phage DNA from host restriction enzymes.

Isomeric N-methyl-7-deazaguanines: Synthesis, structural assignment, and inhibitory activity on xanthine oxidase

The N-methyl isomers of 2-amino-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-one1 (2a) have been synthesized regiospecifically and their structures assigned. The 3-methyl thylcompound was obtained by alkylation of the parent chromophore 2a with dimethyl sulfate, and the 1-methyl isomer was obtained by condensation of ethyl 2-cyano-4,4-diethoxybutyrate with N-methyylguanidine and subsequent cyclization. Methylation of 2-amino-4-chloro-7H-pyrrolo[2,3-d]pyrimidine, however, with methyl iodide in the presence of 50% NaOH, by phase-transfer techniques, followed by the replacement of halide by hydroxyl, yielded the 7-methyl compound. The N-methyl isomers of 2a were all found to be inhibitors of xanthine oxidase from cow’s milk. While the 3-methyl isomer exhibits a K(i) of 40 muM, the 7- and 1-isomers show K(i) values of 4.5 and 3 muM, respectively.
