Viral transcription has not been routinely targeted in the development of new antiviral drugs. This crucial step of the viral cycle depends on the concerted action of cellular and viral proteins such as NF-κB and Tat. In the present study, stilbene-related heterocyclic compounds including benzalphthalide, phthalazinone, imidazoindole and pyrimidoisoindole derivatives are tested for their anti-HIV activity. Original assays based on recombinant viruses were used to evaluate HIV replication inhibition and stably transfected cell lines were used to evaluate inhibition of Tat and NF-κB proteins. Some of the stilbene-related heterocyclic compounds analysed displayed anti-HIV activity through interference with NF-κB and Tat function. Moreover, compounds inhibiting both targets displayed a stronger activity on viral replication.

Several series of dihydrostilbenamide, imidazo[2,1-a]isoindole, pyrimido[2,1-a]isoindole and phthalazinone derivatives were obtained and their vasorelaxant activity was measured on isolated rat aorta rings pre-contracted with phenylephrine (10-5 M). Some phthalazinones attained, practically, the total relaxation of the organ at micromolar concentrations. For the most potent compound 9h (EC50 = 0.43 μM) the affinities for α1A, α1B and α1D adrenergic sub-receptors were determined.

The in vitro antiplasmodial activity of some dihydrostilbenamides, phtalazinones, imidazo[2,1-a]isoindole and pyrimido[2,1-a]isoindole derivatives related to the natural dihydrostilbenoid isonotholaenic acid is reported. The evaluation was performed on cultures of F32 strain of Plasmodium falciparum and potent representative compounds were also evaluated in the ferriprotoporphyrin IX biomineralization inhibition test (FBIT). Compounds having the imidazo[2,1-a]isoindole skeleton were the most active and one compound of this group resulted to be as potent as chloroquine, but acting through a mechanism different that of the inhibition of heme biomineralization.

This invention is concerned with tetrahydropyrimidinyl phenyl carbonyl acid addition salts, imidazolinyl phenyl carbonyl acid addition salts, dihydroimidazoisoindolols, tetrahydropyrimidoisoindolols, and tetrahydropyrimidoisoindolol acid addition salts which are all pharmacologically efficacious as anti-depressants. The tetrahydropyrimidinyl phenyl carbonyl acid addition salts, the tetrahydropyrimidoisoindolols and the tetrahydropyrimidoisoindolol acid addition salts are also efficacious as diuretics while the imidazolinyl phenyl carbonyl acid addition salts and the dihydroimidazoisoindolols are efficacious as anorexiants. This invention is also concerned with several processes for the preparation of these compounds.
