Preparation and mesomorphic properties of highly fluorinated materials incorporating S-ethyl-lactate

, p. 91 - 98 (2001)
The synthesis of three different chiral short molecular weight compounds have been reported. The overall compounds incorporate a linear perfluorinated tail and S-ethyl-Iactate as chiral moiety. Each compound differ to the other by one molecular parameter: a spacer carbonyloxy or oxycarbonylmethoxy or by the presence or not of an ester function between the two aromatic rings of the mesogenic core. The synthesis have been carried out from 2-F-hexylethyliodide or 2-F-hexylethanol. The mesomorphic properties have been characterized by light microscopy and by differential thermal analysis showing the peculiar effect of the spacer. The two biphenyl derivatives exhibit liquid crystal properties over a wide temperature range. The mesophase for both compounds is smectic of type A. However, the introduction of an ester function in the core contribute to enhance the melting temperature and suppress the liquid crystal behavior.

The hedgehog (Hh) signaling pathway is involved in diverse aspects of cellular events. Aberrant activation of Hh signaling pathway drives oncogenic transformation for a wide range of cancers, and it is therefore a promising target in cancer therapy. In the principle of association and ring-opening, we designed and synthesized a series of Hh signaling pathway inhibitors with phenyl imidazole scaffold, which were biologically evaluated in Gli-Luc reporter assay. Compound 25 was identified to possess high potency with nanomolar IC50, and moreover, it preserved the inhibition against wild-type and drug-resistant Smo-overexpressing cells. A molecular modeling study of compound 25 expounded its binding mode to Smo receptor, providing a basis for the further structural modification of phenyl imidazole analogs.
