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.
