Analogues of the potent adenosine antagonist 5-(3'-hydroxypropyl)-7-methoxy-2-(3'-methoxy-4'-hydroxyphenyl)benzo[b]furan-3-carbaldehyde (XH-14, 1) with alternate substituents in the 2-, 5- and 7-positions have been synthesised. The affinity of these compounds for the Al adenosine receptor has been evaluated using a [H-3]CPX competitive binding assay. This structure-activity study highlighted the importance of the 3-formyl and 5-(3-hydroxypropyl) moieties for high receptor affinity. (C) 1998 Elsevier Science Ltd. All rights reserved.

Ailanthoidol showed a strong $anti$-inflammatory effect in a previous result. Ailanthoidol derivatives were prepared for the $anti$-inflammatory test using Sonogashira coupling, iodine induced cyclization and Wittig reaction. $Anti$-inflammatory effects of the prepared ailanthoidol derivatives were examined in lipopolysaccharide (LPS)-stimulated RAW 264-7 macrophages. The results showed that some ailanthoidol derivatives inhibited significantly the production of inflammatory mediator nitric oxide.
