Abstract
A series of quinolino-fused 7-deazapurine (pyrimido[5',4':4,5]pyrrolo[3,2-f]quinoline) ribonucleosides were designed and synthesized. The synthesis of the key 11-chloro-pyrimido[5',4':4,5]pyrrolo[3,2-f]quinoline was based on the Negishi cross-coupling of iodoquinoline with zincated 4,6-dichloropyrimidine followed by azidation and thermal or photochemical cyclization. Vorbrüggen glycosylation of the tetracyclic heterocycle followed by cross-coupling or substitution reactions at position 11 gave the desired set of final nucleosides that showed moderate to weak cytostatic activity and fluorescent properties. The corresponding fused adenosine derivative was converted to the triphosphate and successfully incorporated to RNA using in vitro transcription with T7 RNA polymerase.

Abstract
![]()
A new approach for synthesizing polycyclic heterofused
7-deazapurine
heterocycles and the corresponding nucleosides was developed based
on C–H functionalization of diverse (hetero)aromatics with
dibenzothiophene-S-oxide followed by the Negishi
cross-cooupling with bis(4,6-dichloropyrimidin-5-yl)zinc. This cross-coupling
afforded a series of (het)aryl-pyrimidines that were converted to
fused deazapurine heterocycles through azidation and thermal cyclization.
The fused heterocycles were glycosylated to the corresponding 2′-deoxy-
and ribonucleosides, and a series of derivatives were prepared by
nucleophilic substitutions at position 4. Four series of new polycyclic
thieno-fused 7-deazapurine nucleosides were synthesized using this
strategy. Most of the deoxyribonucleosides showed good cytotoxic activity,
especially for the CCRF-CEM cell line. Phenyl- and thienyl-substituted
thieno-fused 7-deazapurine nucleosides were fluorescent, and the former
one was converted to 2′-deoxyribonucleoside triphosphate for
enzymatic synthesis of labeled oligonucleotides.

Abstract
7-Deazapurine (pyrrolo[2,3-d]pyrimidine) nucleosides are important analogues of biogenic purine nucleosides with diverse biological activities. Replacement of the N7 atom with a carbon atom makes the five-membered ring more electron rich and brings a possibility of attaching additional substituents at the C7 position. This often leads to derivatives with increased base-pairing in DNA or RNA or better binding to enzymes. Several types of 7-deazapurine nucleosides with potent cytostatic or cytotoxic effects have been identified. The most promising are 7-hetaryl-7-deazaadenosines, which are activated in cancer cells by phosphorylation and get incorporated both to RNA (causing inhibition of proteosynthesis) and to DNA (causing DNA damage). Mechanism of action of other types of cytostatic nucleosides, 6-hetaryl-7-deazapurine and thieno-fused deazapurine ribonucleosides, is not yet known. Many 7-deazaadenosine derivatives are potent inhibitors of adenosine kinases. Many types of sugar-modified derivatives of 7-deazapurine nucleosides are also strong antivirals. Most important are 2'-C-methylribo- or 2'-C-methyl-2'-fluororibonucleosides with anti-HCV activities (several compounds underwent clinical trials). Some underexplored areas of potential interest are also outlined.

Abstract
5-alkynyl tubercidin analogues were synthesized and their biological activities were evaluated. It was found that protein kinase A could be activated by 5-alkynyl tubercidin (9a) and cAMP-binding ability to PKA-I was selectively inhibited by it. Molecular modeling showed that the interaction of 9a and PKA-I was associated with the existence of hydrophobic alkynyl group. During the synthesis of tubercidin analogues, a pair of 2'-carbonyl participating abnormal coupling products (11a, 11b) was obtained, the structure was identified by X-ray crystalline diffraction.
