Carboxyarylindoles as nonsteroidal antiinflammatory agents

Abstract: An extensive series of carboxyarylindoles has been evaluated for antiinflammatory activity in the carrageenin paw edema assay. The requirements for optimal antiinflammatory activity in this series are relatively specific: a central pyrrole nucleus with (a) a 3-carboxy-4-hydroxyphenyl moiety substituted directly on the nitrogen, (b) a 2-phenyl group (R2) with a substituent of low electronegativity, (c) absence of a substituent in the 3 position (R3), and (d) a system fused across the 4,5 positions (X), which is… Show more

“…The synthesis of HP129 (20), illustrated in Scheme 9, was described in 1976 [68]. The 1-(3,4-dihydronaphthalen-2-yl)pyrrolidine was obtained by reaction between the ketone and the pyrrolidine.…”

“…Eine stark elektronenziehende Nitrilgruppe sowie eine Methylgruppe zeigten ähnliche Reaktivitäten, und 12 d und 12 e wurden in 57 % bzw. [9i] Schließlich wurde Pyrrol 28, ein nichtsteroidischer Entzündungshemmer, [16] in einer Eintopfsequenz hergestellt (Schema 3 b). Dagegen führte eine stark elektronenschiebende Methoxygruppe zu einer starken Absenkung der Ausbeute, und es konnten nur Spuren des Produkts 12 f isoliert werden.…”

“…59 % Ausbeute isoliert. Nach Entfernen des Lçsungsmittels folgten wir einem bekannten Verfahren [16] und erhitzten das Produkt zusammen mit Anilin 29 in Essigsäure unter Rückfluss. Dies Weitere Umwandlungen der g-Peroxyketone wurden an 1 als Modellsubstrat untersucht (Schema 3 a).…”

“…A new procedure has recently been described, in which fluorophors are produced by irradiation of otherwise non-fluorescent drugs.l We have adapted this method for analysis of the new anti-inflammatory drug, Fendosal, 3-(3-carboxy-4-hydroxyphenyl)-4,5-dihydro-2-phenylbenz(e)indole. 2 The acceptability of the method with regard to precision, accuracy, sensitivity, and specificity has been investigated.…”
