Tumor inhibitory triazenes. 2. Variation of antitumor activity within an homologous series
摘要:
An homologous series of water-soluble, chemically stable analogues of 5-(3,3-dimethyl-1-triazeno)imidazole-4-carboxamide (DTIC) has been prepared with activity comparable to DTIC in an experimental tumor system. The antitumor activity of this series of 3-alkyl-1-(4-carboxyphenyl)-3-methyltriazenes rapidly diminishes at alkyl chain lengths greater than pentyl. Partition coefficients were determined, but no relationship between these and antitumor activity could be established.
在此,开发了一种无金属和无溶剂的方案,用于杂芳基卤化物和胺的 C-N 偶联,在没有任何外部碱的情况下提供了许多杂芳基胺或其盐酸盐。进一步的研究表明,胺的碱性和源自3j'·HCl的 X 射线晶体学分析的特定相互作用在反应中起关键作用。此外,该协议可扩展到克级并适用于药物分子,这证明了其进一步应用的实用价值。

acetylcholine is observed are growing worldwide. In the present study, a series of new arylaminopropanone derivatives with N-phenylcarbamate moiety (1–16) were prepared as potential acetylcholinesterase and butyrylcholinesteraseinhibitors. In vitro enzyme assays were performed; the results are expressed as a percentage of inhibition and the IC50 values. The inhibitory activities were compared with
Compositions, methods, and kits comprising amines are described for use in nucleic acid synthesis. In some embodiments, amines improve nucleic acid synthesis product yield or tolerance to inhibitors of nucleic acid synthesis.
