Isoindolin-1-one and Isoindoline-1,3-dione substituted in the 2-position with an &agr;-(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, TNF&agr; and phosphodiesterase. A typical embodiment is 2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4,5-diaminoisoindoline-1,3-dione.
2-位置上取代了α-(3,4-二取代苯基)烷基基团,4-和/或5-位置上取代了含氮基团的Isoindolin-1-one和Isoindoline-1,3-dione是TNFα和
磷酸二酯酶介导的疾病状态的
抑制剂,并因此在治疗中有用。一个典型的实施例是2-[1-(3-乙氧基-4-
甲氧基苯基)-2-甲基磺酰基乙基]-4,5-二
氨基Isoindoline-1,3-dione。
