Discovery of 4-Amino and 4-Hydroxy-1-aroylindoles as Potent Tubulin Polymerization Inhibitors
摘要:
1-Aroylindoline, 1-aroyl-1,2,3,4-tetrahydroquinoline, and 1-aroylindole derivatives were synthesized and evaluated for anticancer activity. The 4-amino and 4-hydroxy-1-aroylindoles 26 and 27 with IC(50) Of 0.9 and 0.6 mu M, respectively, exhibited antitubulin activity superior or comparable to that of colchicine and combretastatin A-4. They also showed antiproliferative activity with IC(50) of 0.3-5.4 nM in a set of human cancer cell lines.

The present invention relates to a series of novel compounds, methods to prevent or treat viral infections in animals by using the novel compounds and to said novel compounds for use as a medicine, more preferably for use as a medicine to treat or prevent viral infections, particularly infections with RNA viruses, more particularly infections with viruses belonging to the family of the Flaviviridae, and yet more particularly infections with the Dengue virus. The present invention furthermore relates to pharmaceutical compositions or combination preparations of the novel compounds, to the compositions or preparations for use as a medicine, more preferably for the prevention or treatment of viral infections. The invention also relates to processes for preparation of the compounds.

Herein we report a transition-metal- and acid-free protocol for the reductive amination of carbonylcompounds with DMF using a substoichiometric amount of NaH2PO2·H2O. A set of various N,N-dimethylamines were obtained in moderate to excellent yields without chromatographic purification. The general trends and limitations of the method with different formamides as sources of dialkyl-fragments were explored
在此,我们报告了一种使用亚化学计量的 NaH 2 PO 2 · H 2 O的 DMF 对羰基化合物进行还原胺化的无过渡金属和无酸方案。无需色谱纯化即可获得出色的收率。探讨了使用不同甲酰胺作为二烷基片段来源的方法的一般趋势和局限性。
