Abstract:

Reaction of silylated 5-phenylcytosine with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribose, catalyzed with tin tetrachloride, and subsequent methanolysis afforded 5-phenylcytidine (2). This compound reacted with thionyl chloride in acetonitrile to give cyclic sulfite 3 which on heating in dimethylformamide was converted into 2,2'-anhydro-1-(β-D-arabinofuranosyl)-5-phenylcytosine (4). Analogous reaction of compound 2 with thionyl chloride at reflux gave 5'-chloro-5'-deoxy-2',3'-cyclic sulfite 5. Its heating in dimethylformamide afforded 5'-chloro-2,2'-anhydro derivative 6, mild alkaline hydrolysis led

Thirty novel 5-(3-(substituted phenyl)-4,5-dihydroisoxazol-5-yl)-2-methoxyphenyl derivatives were synthesized and evaluated for their antitumour activity. The bioassays showed that the 2-fluorobenzoyl derivative 6ai, the 4-trifluoromethylbenzoyl derivative 6ah, and the 3-trifluoromethyl isoxazole derivatives (6ch and 6ci) were highly effective against PC-3 cells. The IC50 values of 6ah and 6ai against PC-3 cells were 1.5 and 1.8 μg mL–1, respectively.

This article presents methods for synthesis of 3-amino derivatives of cyclohexanespiro-5-(2-thiohydantoin) and cyclohexanespiro-5-(2,4-dithiohydantoin). It was found out that the treatment of cyclohexanespiro-5-(2-thiohydantoin) with hydrazine hydrate under different reaction conditions led to obtaining of 3-amino derivative and 2-hydrazone of the initial compound. As a result of thionation of 3-aminocyclohexanespiro-5-hydantoin with P4S10 or Lawesson’s reagent, the corresponding dithio-analogue was synthesized. The structures of the products obtained were verified by IR, 1H NMR, 13C NMR and m

Recently the Peterson lab discovered a promising anticancer adenosine derivative-- 2´,3´-bis-O-tert-butyldimethylsilyl-5´-deoxy-5´-[N-(methylcarbamoyl)amino]-N6-(N-phenylcarbamoyl)adenosine. This compound showed selective toxicity against human colon cancer cells in vitro with LC50's = 6--10 µM. It was hypothesized that the lead compound exerted its cytotoxic effects by interacting with a protein kinase. A systematic Structure Activity Relationship (SAR) was undertaken in an attempt to increase the kinase-binding affinity of the lead compound. Many regions of the lead compound were examined: t

Abstract:

Considering the importance of nitrogen-rich heterocycles in drug discovery, a novel strategy towards heterocycle synthesis was envisioned using cyanamide chemistry. Synthesis which involve mild conditions, avoids multi-step sequence and non-toxic reagents are desirable for generation of large combinatorial libraries of drug molecules. We envisaged that the NCN linkage of the cyanamide as well as the concomitant use of the nucleo-and electrophilic centres of the cyanamide could provide a novel synthetic route towards nitrogen heterocycles.

Abstract:

Two different chromeno-pyrimidine derivatives were synthetized in the ionic liquid catalyzed reaction of barbituric acid and substituted salicylaldehydes. The product 5-(7-bromo-2,4-dioxo-1,3,4,5-tetrahydro-2H-chromeno[2,3-d]pyrimidin-5-yl)pyrimidine-2,4,6(1H,3H,5H)-tri-one (CP-1) was obtained in the reaction of barbiruric acid and 5-bromo-2-hydroxybenzaldehyde. The second new product 8,9-dihydroxy-2H-chromeno[2,3-d]pyrimidine-2,4(3H)-dione (CP-2) was yielded in the reaction between barbituric acid and 2,3,4-trihydroxybenzaldehyde. These products were isolated in moderate to good yield after 3
