ABSTRACT<br />

The viral infections are among the most common human diseases and<br />

the drug-resistant virus strains is a complex problem in the treatment, reinforced<br />

the design and synthesize of new chemical entities more efficient and less<br />

toxics. In this work we report the study of a new moieties inhibition of Herpes<br />

Simplex Virus-1 (HSV-1)<br />

In this work, we assess the structural features and electronic properties<br />

of a series of ten 1-hydroxyacridone derivatives (1a–j) recently described as a<br />

new class of non-nucleoside inhibitors of Herpes Simplex Virus-1 (HSV-1).<br />

Based on these molecules, we applied rigid analogue and isostérica<br />

replacement approaches to design and synthesize nine new 3Hbenzo[b]pyrazolo[3,4-h]-1,6-naphthyridine<br />

derivatives (2a–i) and determination<br />

the activity against HSV-1. The biological and computational results of these<br />

new molecules were compared with 1-hydroxyacridones. An inhibitory profile<br />

was observed in 10-Cl substituted 3H-benzo[b]pyrazolo[3,4-h]-1,6-naphthyridine<br />

derivative (2f), which presents the same substituent at the analogous position of<br />

1-hydroxyacridone derivative (1b). The structure–activity relationship (SAR)<br />

studies pointed out the 10-position next to nitrogen atom as important for the<br />

anti-HSV-1 profile in the pyrazolo-naphthyridine derivatives tested. The most<br />

potent acridone and pirazolo naphthridine derivatives were also submitted to an<br />

in silico ADMET screening in order to determine their overall drug-score, which<br />

confirmed their potential antiviral profile.<br />

All theoretical studies and biological activity results reinforced the<br />

promising profile antiviral but is important new further experimental investigation<br />

there derivates.
