The invention concerns pyrrole derivatives of general formula (I) wherein: R
1
is CONH
2
, CN, carboxy, alkyloxycarbonyl, or acyl; R
2
is a H atom, a halogen atom, a CN, alkyl, alkyoxy, alkenyl or trihalogenomethyl radical; R
3
is a H atom or a halogen atom, or an alkyl or OH radical; Het is pyridyl, pyridyl N-oxide or thiazolyl; R
4
is a H atom or a halogen atom, an alkylthio or alkyloxy radical; and R
5
is a H atom, or a hydroxy or alkyloxy radical; provided that when R
3
, R
4
and R
5
are H atoms and Het is a pyridin-2-yl radical, then R
1
cannot be acetyl or methyloxycarbonyl and R
2
is a H atom, or R
1
cannot be propionyl and R
2
methyl, the C
1
-C
4
alkyl and C
2
-C

alkenyl radicals being linear or branched, as the case may be in the form of stereoisomers or their mixtures and/or their salts when they exist. Said derivatives are particularly useful for treating and preventing diseases wherein are involved herpes family viruses and/or wherein are involved cytokines including TNF&agr;.
该发明涉及一般式(I)的吡咯衍生物,其中:R1为CONH2,CN,羧基,烷氧羰基或酰基; R2为氢原子,卤素原子,CN,烷基,烷氧基,烯基或三卤甲基基团; R3为氢原子或卤素原子,或烷基或OH基团; Het为吡啶基,吡啶N-氧化物或噻唑基; R4为氢原子或卤素原子,烷基硫基或烷氧基基团; R5为氢原子或羟基或烷氧基基团; 前提是当R3,R4和R5为氢原子且Het为吡啶-2-基团时,R1不能为乙酰或甲氧羰基,R2为氢原子,或R1不能为丙酰基,R2为甲基。其中的C1-C4烷基和C2-C4烯基基团可以是线性的或分支的,可以形成立体异构体或它们的混合物以及存在时的盐。这些衍生物特别适用于治疗和预防涉及疱疹病毒家族和/或涉及细胞因子包括TNF&agr;的疾病。
