Rm. Abdelrahman et al., SYNTHESIS OF SOME NEW HETEROBICYCLIC COMPOUNDS CONTAINING SPIRO-1,2,4-TRIAZINE MOIETY AS POTENTIAL ANTI-HIV AND ANTICANCER AGENTS, Die Pharmazie, 49(11), 1994, pp. 811-814
A number of heterobicyclic compounds such as 1,3,5-thiazine, thiazolid
inone, pyrimidine, pyrimidinedione, imidazole, quinazolinone and 1,2,4
-triazinone derivatives have been synthesized by reaction of ioxo-6-sp
iro-(9'-fluorene)-1,2,4-triazin-5(4H)-one (1) with sulphur/nitrogen co
mpounds in neutral or alkaline media. Structure elucidation of the new
compounds have been carried out with the help of elemental analysis a
nd spectral data. Some of these compounds were tested for in vitro ant
i HIV and anticancer activities.
