The present invention relates to new carbonyl 3R,4R-ethyl-[(1-methyl-1H-imidazol-5-yl)methyl]-2-pyrrolidinone derivatives carrying a carboxyester-type lipophilic moiety on the pyrrolidinone nitrogen. More particularly, the present invention concerns new N-substituted carbonyl-3R,4R-ethyl-[(1-methyl-1H-imidazol-5-yl)methyl]-2-pyrrolidinone derivatives of the formula (I):
wherein R is an optionally substituted hydrocarbon group, and pharmaceutically acceptable acid addition salts thereof.
The new compounds of the formula (I) are potent ocular hypotensives that are valuable antiglaucoma agents. They are also targeted for use in the treatment of so-called dry eye.
本发明涉及新的羰基-3R,4R-乙基-[(1-甲基-1H-咪唑-5-基)甲基]-2-吡咯烷酮衍生物,其吡咯烷酮氮上带有羧酯型亲脂分子。 更具体地说,本发明涉及式(I)的新的 N-取代羰基-3R,4R-乙基-[(1-甲基-1H-咪唑-5-基)甲基]-2-吡咯烷酮衍生物:其中 R 是任选取代的烃基,以及它们的药学上可接受的酸加成盐。 式(I)的新化合物是有效的降眼压药,是有价值的抗青光眼药物。 它们还可用于治疗所谓的干眼症。
The present invention relates to new racemic and optically active compounds containing a first moiety derived from a pilocarpine compound in which the furanone ring of pilocarpine is replaced by a hetero-ring containing a secondary nitrogen heteroatom, and a second moiety derived from an epinephrine compound or a β-adrenergic blocking compound, linked at the secondary nitrogen atom of the furanone-replacing hetero-ring of the pilocarpine compound and at the hydroxyl group of the epinephrine compound or of the β-adrenergic blocking compound, via a carbonyl linker, and pharmaceutically acceptable acid addition salts thereof.
The new compounds of the present invention are potent ocular hypotensives exhibiting minimal deleterious pupillary effects.
