Abstract: | Some new pyrimido2,1-b]benzothiazole and benzothiazolo2,3-b]quinazoline derivatives have been synthesized and tested for their antitumor and antiviral activities. Among therm, compounds 5c and 8d exhibited a broad spectrum antitumor activity with full panel (MG-MID) median growth inhibition (GI50) of 11.0 and 11.9 mumol/l, respectively. On the other hand, compounds 5c and 5d showed potential activity against Herpes simplex type-1(HSV-1) with 61 and 50% reduction in the viral plaques, respectively. The detailed synthesis, spectroscopic and biological data are reported. |
