[Problems to be Solved] To provide a novel compound having antiviral activity, especially inhibitory activity against HIV integrase, a pharmaceutical composition, especially anti-HIV drug, containing the same.
[Means to Solve the Problem] A compound of the formula:
(wherein:
R
1
is optionally substituted aralkyl;
R
2
and R
3
are each independently hydrogen, optionally substituted alkyl, optionally substituted amino, optionally substituted alkenyl or optionally substituted alkoxy (provided that each substituent for “optionally substituted” is a noncyclic group);
R
4
is hydrogen, optionally substituted carboxy, optionally substituted formylamino, optionally substituted carbamoyl, optionally substituted amino (provided that a substituent on amino in “optionally substituted formylamino”, “optionally substituted carbamoyl” and “optionally substituted amino” may form an optionally-substituted N-atom containing heterocyclic ring together with an adjacent N atom), optionally substituted alkyl, optionally substituted alkenyl, optionally substituted aryl, or optionally substituted heteroaryl) or a salt thereof.
【需要解决的问题】提供一种具有抗病毒活性,特别是对HIV整合酶具有抑制活性的新型化合物,以及包含该化合物的制药组合物,特别是抗HIV药物。
【解决问题的方法】 化合物的化学式为:(其中:R1是可选取代的芳基甲基;R2和R3分别是氢、可选取代的烷基、可选取代的氨基、可选取代的烯基或可选取代的烷氧基(提供“可选取代”中的每个取代基均为非环状基);R4是氢、可选取代的羧基、可选取代的甲酰胺基、可选取代的氨基甲酰胺基、可选取代的氨基(在“可选取代的甲酰胺基”、“可选取代的氨基甲酰胺基”和“可选取代的氨基”中,氨基上的取代基可以与相邻的N原子一起形成一个含有可选取代的N原子的杂环环),可选取代的烷基、可选取代的烯基、可选取代的芳基或可选取代的杂环芳基)或其盐。
