Synthesis and Biological Evaluation of New 3-Phenyl-1-[(4-arylpiperazin-1-yl)alkyl]-piperidine-2,6-diones
A set of 13 alkyl derivatives of 3-phenylpiperidine-2,6-dione were synthesized. Newly obtained compounds were investigated in vitro against HIV-1 and other selected viruses. The benzyl 3f and fluorophenyl 3g derivatives showed moderate protection against CVB-2 and the compound 3g also against HSV-1. Derivatives were tested also for their antibacterial and antifungal activity. The molecular structures of 3a and 3d were determined by an X-ray analysis
Biological evaluation of 10-(diphenylmethylene)-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives
AbstractAntibacterial and antifungal activity of 10-(diphenylmethylene)-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives were examined by the disc-diffusion method (growth inhibition zone diameter in agar medium). The MIC's for the most active agents were determined. Title compounds were also evaluated in vitro against representatives of different virus classes. Most of the tested compounds exhibit activity against CVB-2 virus
Derivatives of benzo[b]furan. Part I. Conformational studies of khellinone and visnaginone
Synthesis and Evaluation of in Vitro Biological Activity of 4-Substituted Arylpiperazine Derivatives of 1,7,8,9-Tetrachloro-10,10-dimethoxy-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione
A series of twenty arylpiperazine derivatives of 1,7,8,9-tetrachloro-10,10-dimethoxy-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione have been prepared. These derivatives were tested in vitro with the aim of identifying novel lead compounds active against emergent and re-emergent human and cattle infectious diseases (AIDS, hepatitis B and C, tuberculosis, bovine viral diarrhea). In particular, these compounds were evaluated in vitro against representatives of different virus classes, such as a HIV-1 (Retrovirus), a HBV (Hepadnavirus) and the single-stranded RNA+ viruses Yellow fever virus (YFV) and Bovine viral diarrhea virus (BVDV), both belonging to the Flaviridae. Compounds 2c, 2g and 3d showed a modest activity against CVB-2. The molecular structures of the starting imide 1 and one of propyl-piperazine derivatives, 3b, have been determined by an X-ray crystallography study
Synthesis of Conformationally Constrained Aryl- or Heteroarylpiperazinyl Derivatives of Selected Imides as 5-HT1A Receptor Ligands
The preparation of a number of cyclic imide 5-HT1A receptor ligandderivatives has been described. Their structures were conformationally constrained byintroducing rigid linkers containing unsaturated bonds or aromatic benzene rings. Thesecompounds are expected to possess anxiolytic and antidepressant activity

9-Methyl-3,5-dioxo-4-azatricyclo[5.2.2.02,6]undec-8-ene-1,8-diyl Diacetate
9-Methyl-3,5-dioxo-4-azatricyclo[5.2.2.02,6]undec-8-ene-1,8-diyl diacetatewas synthesized from 2-methylcyclohexane-1,3-dione and 1H-pyrrole-2,5-dione. The title compound was characterized by 1H NMR, 13C NMR, elemental analysis and MS
