Biological Evaluation of 3-Azaspiro[Bicyclo[3.1.0]Hexane-2,5'-Pyrimidines] as Potential Antitumor Agents.

A series of heterocyclic compounds containing spirofused barbiturate and 3-azabicyclo[3.1.0]hexane frameworks have been studied as potential antitumor agents.

Identification of Spiro-Fused Pyrrolo[3,4-]pyrrolizines and Tryptanthrines as Potential Antitumor Agents: Synthesis and In Vitro Evaluation.

A series of heterocyclic compounds containing a spiro-fused pyrrolo[3,4-]pyrrolizine and tryptanthrin framework have been synthesized and studied as potential antitumor agents. Cytotoxicity of products was screened against human erythroleukemia (K562) and human cervical carcinoma (HeLa) cell lines. Among the screened compounds.
