Novel phthalimide derivatives, designed as leukotriene D4 receptor antagonists
摘要:
A series of phthalimide acid derivatives was synthesized and evaluated as leukotriene D-4 receptor antagonists. The tetrazolephthalimide LASSBio 552 (7) was shown to be able to inhibit the contractile activity induced by 100 nM of LTD4 in guinea-pig tracheal strips with an IC50 = 31.2 muM. In addition, LASSBio 552 (7) has been showed to present a better efficacy than zafirlukast (1) used as standard. (C) 2002 Elsevier Science Ltd. All rights reserved.

Abstract In this paper we describe the synthesis of a new series of substituted 2-(4-alkoxy or 4-acyloxyphenethyl)-phthalimide derivatives (4--11). in good yields (58--87%), exploring the remarkable fast O-alkylation or O-acylation of 2-(4-hydroxyphenethyl)-phthalimide (3) in dry media undermicrowaveirradiation.
