A new method for the synthesis of dihydroimidazo[1,2-a][1,3,5]triazin-4(6H)-ones via copper(I)-catalyzed hydroamination was developed. In addition, for the first time, iodoalkynes were shown to participate in the copper(I)-catalyzed intramolecular hydroamination reaction with exclusive formation of E-isomers.

6-Chloro-2-Aryl-1H-imidazo[4,5-b]pyridine derivatives 1-26 were synthesized and characterized by various spectroscopic techniques. All these derivatives were evaluated for their antiglycation, antioxidant and β-glucuronidase potential followed their docking studies. In antiglycation assay, compound 2 (IC50=240.10±2.50μM) and 4 (IC50=240.30±2.90μM) was found to be

A series of 1-benzylbenzimidazole and 3-benzylimidazo[4,5-b]pyridine substituted in the 2-position by an alkanoic or mercaptoalkanoic acid chain was synthesized for evaluation as potential thromboxane A2/prostaglandin H2 (TXA2/PGH2) receptor antagonists. The affinity of each compound for washed human platelet TXA2/PGH2 receptors

Template-free cross-linking of single-stranded DNA bearing octadiynyl side chains at the 7-position of 8-aza-7-deazapurine moieties with bisfunctional azides is reported employing a Cu(I)-catalyzed azide-alkyne "bis-click" reaction. Bis-adducts were formed when the bis-azide:oligonucleotide ratio was 1:1; monofunctionalization occurred when the ratio

Nitration of substituted (1-deaza)purines using a mixture of tetrabutylammonium nitrate (TBAN) and trifluoracetic acid anhydride (TFAA) was applied to prepare nitrosubstituted (1-deaza)purines at low temperature. The nitro group influences the system twofold: 1) it activates other substituents towards nucleophilic aromatic
