Previous research has shown that 3-(dialkylamino)-5-phenylisoxazoles posses
sing a compact structure were active against HRV-2 and, consequently, prese
nted a type B activity. In this paper, 3-(diethylamino)-5-phenylisoxazoles,
which are structurally more elongated and related to Disoxaril, were synth
esized in view to attempt type A activity against HRV-14. Unfortunately, al
l tested compounds were devoid of activity against HRV-14 (and HIV-1) of ex
hibited great toxicity. (C) 2000 Elsevier Science S.A. All rights reserved.
