Benvenuti nell'Anagrafe della Ricerca d'Ateneo

La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.

Nitric oxide (NO) is a polypotent regulatory molecule involved in a variety of activities, such as the modulation of the catalytic activity of cysteine-containing enzymes. The present study reports the modulation of the HIV-1 reverse transcriptase activity by NO, released by the NO donors 3,3-bis(aminoethyl)-1-hydroxy-2-oxo-1-triazene (NOC-18), (+/-)-(E)-4-ethyl-2-[(E)-hydroxyimino]5-nitro-3-hexenamide (NOR-3), 3-morpholinosydnonimine (SIN-1), 4-(phenylsulfonyl)-3-((2-(dimethylamino) ethyl)thio)furoxan oxalate (SNO-102), and sodium nitroprusside (SNP). NO inhibits dose-dependently the HIV-1 reverse transcriptase activity, Likely due to oxidation of Cys residue(s). Present results, representing a new insight into the modulation mechanism of the HIV-1 reverse transcriptase activity, may be relevant to develop new strategies for inhibition of HIV-1 replication.

Abstract:	Nitric oxide (NO) is a polypotent regulatory molecule involved in a variety of activities, such as the modulation of the catalytic activity of cysteine-containing enzymes. The present study reports the modulation of the HIV-1 reverse transcriptase activity by NO, released by the NO donors 3,3-bis(aminoethyl)-1-hydroxy-2-oxo-1-triazene (NOC-18), (+/-)-(E)-4-ethyl-2-[(E)-hydroxyimino]5-nitro-3-hexenamide (NOR-3), 3-morpholinosydnonimine (SIN-1), 4-(phenylsulfonyl)-3-((2-(dimethylamino) ethyl)thio)furoxan oxalate (SNO-102), and sodium nitroprusside (SNP). NO inhibits dose-dependently the HIV-1 reverse transcriptase activity, Likely due to oxidation of Cys residue(s). Present results, representing a new insight into the modulation mechanism of the HIV-1 reverse transcriptase activity, may be relevant to develop new strategies for inhibition of HIV-1 replication.
