Isoindolin-1-one and Isoindoline-1, 3-dione substituted in the 2-position with an α-(3, 4-disubstituted phenyl)alkyl group and in the 4- and/or 5-position with a nitrogen-containing group are inhibitors of, and thus useful in the treatment of disease states mediated by, TNFα and phosphodiesterase. A typical embodiment is 2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4,5-diaminoisoindoline-1,3-dione.
2-取代为α-(3,4-二取代苯基)烷基的
异吲哚啉-1-酮和
异吲哚啉-1,3-二酮,并在4-和/或5-位置取代含氮基团,可用于抑制并治疗由TNFα和
磷酸二酯酶介导的疾病状态。一个典型的实施例是2-[1-(3-乙氧基-4-
甲氧基苯基)-2-
甲烷基磺酰乙基]-4,5-二
氨基
异吲哚啉-1,3-二酮。
