V. Ambrogi et al., SYNTHESIS, ANTIMICROBIAL AND CYTOSTATIC ACTIVITIES OF SOME DERIVATIVES OF INDOLO[2,3-B]-1,5-BENZOTHIAZEPINE, A NOVEL HETEROCYCLIC RING-SYSTEM, European journal of medicinal chemistry, 28(9), 1993, pp. 659-667
Some derivatives of indolo[2,3-b]-1,5-benzothiazepine, a novel heteroc
yclic ring system, and of its 5,6-dihydroderivative have been obtained
by Fischer indolization of corresponding phenylhydrazones. All the te
tracyclic compounds were studied for their antimicrobial and cytostati
c activities and several of them showed good activity against Gram-pos
itive bacteria and Cryptococci.
