A series of 2-oxo-[1,4]oxazino[3,2-e ]indoles, heteroanalogues of Angelicin, have been synthesized by a multistep sequence consisting of the annelation of the oxazine ring on the indole moiety. The phototoxicity and the antiproliferative activity of the new derivatives were investigated.

A novel synthetic approach to the synthesis of 3-substituted isoindoles through nucleophilic substitution of 3-halo derivatives by charged carbon, and neutral nitrogen, oxygen, and sulfur nucleophiles, assisted by a 1-acyl group, is reported. Aryl-thio-isoindoles, obtained through a direct nucleophilic substitution with sulfur nucleophiles,...

A series of bis-indolylpyrazoles were obtained by cyclization of diketones using hydrazine monohydrate or methylhydrazine in refluxing acetic acid/THF. Three of the derivs. were selected, by the National Cancer Institute (NCI, Bethesda, USA), to be evaluated against the full panel of about 60 human tumor cell lines derived from nine human...

A series of derivatives of new ring system pyrido[4',3':4,5]pyrrolo[2,1-d] [1,2,3,5]tetrazine was obtained from moderate to excellent yields by reaction of 2-diazo-3-ethoxycarbonyl-pyrrolo[2,3- c]pyridine with alkyl- or aryl-isocyanates in dichlorometane at room temperature or at 50 °C under microwave irradiation.

Twelve derivatives of new ring system pyrido[2',3':4,5]pyrrolo[2,1-d][1,2,3,5]tetrazine were prepared in good yields by reaction of 2-diazo-3-ethoxycarbonyl-pyrrolo[3,2-b]pyridine with alkyl- or aryl-isocyanates. Nine derivatives, screened by the National Cancer Institute (Bethesda, MD) for the in vitro one dose primary anticancer assay against...
