Synthesis and biological evaluation of new cytotoxic indazolo[4,3-gh]isoquinolinone derivatives
摘要:
A series of indazolo[4,3-gh]isoquinolinones derivatives have been synthesized to decrease cardiotoxic side effects in comparison to Mitoxantrone. The antiproliferative effects of different side chains were investigated and tested on at least four different cell lines of cervix, ovarian, CNS, NSCLC (non-small-cell lung cancer) and colon carcinoma. In addition to antiproliferative activities, influence on cell cycle and intercalation behavior have been tested. (C) 2013 Elsevier Ltd. All rights reserved.

Aminoalkyl glucosamine phosphate compounds that are adjuvants and immunoeffectors are described and claimed. The compounds have a 2-deoxy-2-amino glucose in glycosidic linkage with an aminoalkyl (aglycon) group. Compounds are phosphorylated at the 4 or 6 carbon on the glucosamine ring and comprise three 3-alkanoyloxyalkanoyl residues. The compounds augment antibody production in immunized animals as well as stimulate cytokine production and activate macrophages. Methods for using the compounds as adjuvants and immunoeffectors are also disclosed.
reactions of alcohols with silyl chlorides in the presence of N-methylimidazole were significantly accelerated by the added iodine, and on this basis a general, and high yielding method for efficient silylation of primary, secondary, and tertiary alcohols was developed.
The synthesis of a series of thirty-eight new modified dinucleotides and dinucleotide conjugate analogues of d-5′ApC3′ is described. The inhibitory activity of these compounds toward HIV-1 integrase was examined in enzymatic assays using the natural dinucleotide as a reference. Among the compounds, a perylene-dinucleotide conjugate has shown a two micromolar anti-integrase activity due to the presence

of an underexplored dynamic covalent reaction for the synthesis of stimuli-responsive [2]rotaxanes. The formamidinium moiety lies at the heart of these mechanically interlocked architectures, because it enables both dynamic covalent exchange and the binding of simple crown ethers. We demonstrated that the rotaxane self-assembly follows a unique reaction pathway and that the complex interplay between

Aminoalkyl glucosaminide phosphate (AGP) compounds that are adjuvants and immunoeffectors are described and claimed. The compounds have a 2-deoxy-2-amino glucose in glycosidic linkage with an aminoalkyl (aglycon) group. Compounds are phosphorylated at the 4 or 6 carbon on the glucosaminide ring and comprise three 3-alkanoyloxyalkanoyl residues. The compounds augment antibody production in immunized animals as well as stimulate cytokine production and activate macrophages.
