Novel isopentenyladenosine analogues: Synthesis, characterization, and evaluation of antiproliferative activity on bladder carcinoma cells

Isopentenyladenosine (iPA), a member of the cytokinin family of plant hormones, exerts a marked antiproliferative activity on some leukemic and epithelial cancer cell lines. To characterize the molecular moieties required for the in vitro antitumor activity of the molecule and to obtain cytostatic iPA derivatives potentially useful as chemotherapeutic agents, N9-acyclic analogues have been synthesized using regioselective Mitsunobu reaction and characterized by elemental analyses, 1H and 13C NMR. These compounds were analyzed for their activity on human bladder cancer cell lines. In this study, we report that iPA inhibited the proliferation but not the migration of human bladder cancer cells, while the newly synthesized analogues revealed no significant cytostatic activity apart from the compound with a saturated double bond of the isopentenyl chain. These results indicate that the integrity of the ribose ring is required for the cytostatic activity of iPA.

FLAME RETARDANT ITACONIC ACID-BASED COMPOUNDS

A flame retardant itaconic acid-based compound, a process for forming a flame retardant polymer, and an article of manufacture comprising a material that contains a flame retardant itaconic acid-based polymer are disclosed. The flame retardant itaconic acid-based compound has variable moieties, which include methylene bridge groups, carbonyl groups, vinyl groups, functionalized groups, phenyl-substituted flame retardant groups, and/or functionalized flame retardant groups. The process for forming the flame retardant polymer includes forming a phosphorus-based flame retardant molecule, forming an itaconic acid derivative, chemically reacting the phosphorus-based flame retardant molecule and the itaconic acid derivative to form a flame retardant itaconic acid-based compound, and incorporating the itaconic acid-based flame retardant compound into a polymer to form the flame retardant polymer.

Design, synthesis and X-ray crystallographic study of NAmPRTase inhibitors as anti-cancer agents

NAmPRTase (PBEF/Visfatin) plays a pivotal role in the salvage pathway of NAD+ biosynthesis. NAmPRTase has been an attractive target for anti-cancer agents that induce apoptosis of tumor cells via a declining plasma NAD+ level. In this report, a series of structural analogs of FK866 (1), a known NAmPRTase inhibitor, was synthesized and tested for inhibitory activities against the proliferation of cancer cells and human NAmPRTase. Among them, compound 7 showed similar anti-cancer and enzyme inhibitory activities to compound 1. Further investigation of compound 7 with X-ray analysis revealed a co-crystal structure in complex with human NAmPRTase, suggesting that Asp219 in the active site of the enzyme could contribute to an additional interaction with the pyrrole nitrogen of compound 7.
