BINOL-amino acid conjugates as triggerable carriers of DNA-targeted potent photocytotoxic agents

Mild photoactivation of new BINOL-amino acid and -amino ester conjugates (BINOLAMs) yielded alkylating and DNA cross-linking agents with high photoefficiency and superior cytotoxicity. Detection of the transient electrophile, by laser flash photolysis (LFP), suggests that BINOL-quinone methides (QMs) are key intermediates in the process. QMs trapping by water, monitored in a time-dependent product distribution analysis, demonstrated that the phototriggered reactivity of BINOLAMs as bis-alkylating agents is the result of a two-step process involving sequential photogeneration of monoalkylating QMs. Light activation of the BINOL-L-amino esters produced cytotoxic QMs very effective against human tumor LoVo cells with EC50 in the 130-230 nM range. Trimethylpsoralen (PS) is about 4 times less potent than our newly tested compounds. BINOL-L-proline methyl ester showed notable photoselectivity because it displayed cytotoxic effects upon irradiation only and was able to efficiently reach the target DNA inside the cells, where it forms both alkylated and cross-linked species.

Strong Aggregation-Induced CPL Response Promoted by Chiral Emissive Nematic Liquid Crystals (N*-LCs)

In this paper we designed a kind of aggregation-induced emission (AIE) chiral fluorescence emitters (R/S-BINOL-CN enantiomers) in the aggregate state. Chiral emissive nematic liquid crystals (N*-LCs) prepared by doping this kind of AIE-active R/S-BINOL-CN enantiomers into a common achiral nematic liquid crystal (N-LC, E7) can self-assemble as the regularly planar Grandjean texture leading to high luminescence dissymmetry factor (glum) of aggregation-induced circularly polarized luminescence (AI-CPL) signal up to 0.41, which can be attributed to dipolar interactions from polar cyano groups and π–π interactions between binaphthyl moiety of the dopant R/S-BINOL-CN and biphenyl group of the host molecules (E7).
