53 dl g−1. These polymers are opticallyactive, thermally stable and soluble in polar aprotic solvents such as DMF, DMSO, NMP, DMAc, and sulfuric acid. All of the above polymers were fully characterized by IR spectroscopy, 1H NMR spectroscopy, elemental analyses, specific rotation and thermal analyses. Some structural characterizations and physical properties of these opticallyactive PEIs and Co-PEIs have

This investigation has explored the properties of 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BDTA) derivatives with regard to their being prospective inhibitors of hexokinase II (HKII). A pluripotent embryonic carcinoma cell line P19 (ECC), was used as the biological target for newly generated potentialinhibitors of HKII. The results obtained from Virtual High-Throughput Screening (VHTS),
