Neuronal nicotinic acetylcholine receptors (nAChRs) form a family of ACh-gated cation channels made up of different subtypes. They are widely distributed in peripheral and central nervous systems and are involved in complex cerebral processes as learning, memory, nociception, movement, etc. The possibility that subtype-selective ligands be used...

The effects of quinacrine and minocycline on the toxicity induced by hPrP90–231 were studied. By mild thermal denaturation, hPrP90–231 can be converted in a toxic PrPSc-like structure affecting the survival of SH-SY5Y cells. Quinacrine and minocycline prevented hPrP90–231-induced toxicity interfering with different mechanisms: protective...

Positive inotropic agents are fundamental in the treatment of heart failure; however, their arrhythmogenic liability and the increased myocardial oxygen demand strongly limit their therapeutic utility. Pursuing our study on cardiovascular activities of lupin alkaloid derivatives, several 2-(4-substituted-phenyl)-2-dehydrosparteines and...

A set of novel riminophenazine derivatives has been synthesized and evaluated for in vitro activity against chloroquine-sensitive (CQ-S) and chloroquine-resistant (CQ-R) strains of Plasmodium falciparum and against different species of Leishmania promastigotes. Most of the new compounds inhibited the growth of Leishmania promastigotes as well...

On the pattern of the potent and selective butyrylcholinesterase (BChE) inhibitors ethopropazine and Astra1397, sets of quinolizidinyl derivatives of bi- and tricyclic (hetero)aromatic systems were studied as dual, or BChE-selective inhibitors. All compounds exhibited activity against both cholinesterases, but inhibition of BChE was generally...

A library of 64 benzotriazole derivatives (17 of which were [4-(benzotriazol-2-yl)phenoxy]alkanoic acids) were screened for antiviral activity against a panel of twelve DNA and RNA viruses. Twenty-six compounds (12 of which were [4-(benzotriazol-2-yl)phenoxy]alkanoic acids) displayed activity against one or more viruses. CVB-5, RSV, BVDV, Sb-1...

Twenty-six 9-aminoacridine derivatives were evaluated in cell-based assays for cytotoxicity and antiviral activity against a panel of 10 RNA and DNA viruses. While seven compounds (9, 10, 14, 19, 21, 22, 24) did not affect any virus and two (6, 11) were moderately active against CVB-5 or Reo-1, 17 compounds exhibited a marked specific activity...

Seventy-six 2-phenylbenzimidazole derivatives were synthesized and evaluated in cell-based assays for cytotoxicity and antiviral activity against a panel of 10 RNA and DNA viruses. The most commonly affected viruses were, in decreasing order, CVB-2, BVDV, Sb-1, HSV-1, and YFV, while HIV-1 and VSV were not affected, and RSV, VV and Reo-1 were...

A library of eighty-six assorted benzimidazole derivatives was screened for antiviral activity against a panel of ten RNA and DNA viruses. Fifty-two of them displayed different levels of activity against one or more viruses, among which CVB-5, RSV, BVDV and Sb-1 were the most frequently affected. In particular, fourteen compounds exhibited an...
