modifications suggested by the molecular modelling were verified by the synthesis of the designed molecules and by the evaluation of their in vitro activities against two lung tumour cell lines, A549 and H226. 2-(E)-2-[5′-(Dibutylamino)-2,2′-bithien-5-yl]vinyl}-1-methylquinoliniumiodide exhibited in vitro antiproliferative activity two orders of magnitude higher than that of the most active compound

design new trans 2-(thiophen-2-yl)vinyl heteroaromatic iodides with antiproliferative activity. The synthesis and in vitro antitumor tests on two cell lines (MCF-7 and LNCap) confirmed Volsurf predicted activity values. An Almond model, derived to have an overall structural insight on the above compounds, supported the validity of Volsurf and provided guidelines for the synthesis of new compounds.
The synthesis and characterisation of new trans 2-(thiophen-2-yl)vinyl pyridinium, imidazolium and quinoilinium iodides is reported together with their solvatochromic shifts and EFISH characterization. 2-(E)-2-[5′-(dibutylamino)-2,2′-bithien-5-yl]vinyl}-1-methyl pyridinium and quinolinium iodides display high μ.βvec values up to 1200 × 10−48 esu. The promising non-linear optical (NLO) properties of this new family of chromophores, which can be further improved by the design of highly efficient systems exploiting the donor and acceptor properties of both heteroaromatic rings and substituents, make them suitable candidates for second harmonic generation imaging with interesting biological applications.

A dataset of 50 compounds was used to generate a QSAR model and to design 9 new heteroaryl ethylenes. These compounds were synthesized, tested in vitro and a significant agreement with in silico predictions observed. Studies using Laser Scanning Confocal Microscopy pointed out that the compounds may act by different mechanisms.

photochemical and photophysical study on three quinolinium iodides, free and complexed with DNA, was carried out by stationary and pulsed techniques. The comparison with the behaviour of pyridinium analogues pointed to a reduction in the photoisomerization yield of these compounds in favour of fluorescence and internal conversion. These quinoliniumsalts showed a good affinity towards salmon DNA with
