Following the antiviral screening of a wide series of new angular and linear N-tricyclic systems both in silico and in vitro, the [4,7]phenantroline nucleus emerged as a new ring system endowed with activity against viruses containing single-stranded, positive-sense RNA genomes (ssRNA+). Here, we report our new pathway to the synthesis of this nucleus and of several related derivatives, as well as the results of both cell-based antiviral assays and molecular dynamics simulations. In the antiviral screening, several compounds (9 and 16-20) showed to be fairly active against BVDV, CVB-2, and Polio 1 (EC50, 6-25 μM). According to molecular dynamics simulations, compounds (15) and (17) emerged for its potency against the HCV NS5B, with a calculated IC50 of 11-12 μM.
The Influence of Chlorine and Sulphonate Substituents on the Visible Absorption Maxima of Some Azo Dyes

A total of 110 arylazo dyes have been prepared, based on five benzenoid and heterocyclic coupling components, and containing combinations of chlorine and sulphonate (sulpho) substituents in the diazo components.Their visible absorption maxima have been analysed in order to determine the degree to which chloro and sulfo substituent influences are constant and transferable, both within a series, and between series.Additivity is found to pertain, if allowances are made for steric effects.A 2-sulpho group alone can induce nonplanarity, depending on the nature of the coupling component.The 2-sulpho-3-chloro combination is particularly responsible for hypsochromic shifts unexpected on the basis of strict additivity.Computer-aided molecular modelling studies have clarified the steric interactions present.Di-ortho-substitution also induces nonplanarity and hypsochromic effects.There is some evidence for non-equivalence of a substituent in the two distinct meta-orientations, although MO calculations do not reproduce this behaviour.

There is provided a method for controlling the larvae of heel flies which parasitize ruminants and other warm-blooded animals by administering to said animals an effective amount of an unsubstituted or substituted phenylene bis[imino(thio)carbonyl]diphosp
