Triazine-cored dendritic molecules containing multiple o-carborane clusters

A series of C3-symmetricaltriazine-cored small dendritic molecules containing three to nine peripheral o-carborane clusters were synthesized through Cu(I)-catalyzedazide–alkyne cycloaddition reactions. The newly synthesized molecules containing multiple o-carborane moieties were characterized using nuclear magnetic resonance and matrix-assisted laser desorption/ionization-time of flight mass spectral analysis. The biological evaluation of these three to nine cage dendrimers was performed using breast cancer cells (Michigan Cancer Foundation 7). All these dendritic compounds showed cytotoxicity toward breast cancer cells, and the toxicity increased as the number of peripheral o-carboranes increased. The 9-cage molecule showed the highest cytotoxicity, and the half maximal inhibitory concentration (IC50) value was found to be 80.67 ng/ml. Its cytotoxicity was significantly higher than the common chemotherapy agent cisplatin. As expected, the boron-richo-carborane-appended molecules showed high thermal stability. The thermal stability increased as the number of peripheral o-carborane moieties increased.

s-Triazine-based functional monomers with thermocrosslinkable propargyl units: Synthesis and conversion to the heat-resistant polymers

Three s-triazine-based functional monomers with thermo-polymerizable propargyl-ether units were synthesized by a facile procedure. These monomers can be thermally cured to form the crosslinked networks, which showed 5-wt% loss temperature of up to 400?°C and the char yields of more than 50% at 1000?°C. Moreover, the crosslinked networks exhibited the coefficients of thermal expansion (CTE) of below 43?ppm?°C?1 varying from 30 to 300?°C and glass transition temperatures (Tg) of up to 290?°C, respectively. These monomers were also used to improve the thermostability of a commercial bismaleimide (4,4′-bismaleimidodiphenylmethane). The results indicated that blending the bismaleimide and the triazine monomers gave the new resins, which showed higher Tg and lower CTE than the bismaleimide, suggesting the triazine monomers can be considered as the modifiers for enhancement of the thermostability of the commercial bismaleimides.

Interaction of carborane-appended trimer with bovine serum albumin: A spectroscopic investigation

The interaction of symmetrical triazine-cored carborane-appended trimer 5 with bovine serum albumin has been investigated using different spectroscopic methods. The intrinsic fluorescence of BSA was quenched by the carborane trimer 5 through the dynamic q

Cofacial Organic Click Cage to Intercalate Polycyclic Aromatic Hydrocarbons

The synthesis of a 3-fold symmetric cofacial organic cage (COC) through Cu(I)-catalyzed azide-alkyne cycloaddition is reported. The COC can function as an efficient receptor for carcinogenic polycyclic aromatic hydrocarbons to intercalate them in its intrinsic cavity through donor-acceptor and π? π stacking interactions. The association constants (Ka) are in the range of 3.7 × 104 to 1.3 × 106 M-1. X-ray diffraction analysis authenticated that the polycyclic aromatic hydrocarbons (PAHs) are intercalated in the interior of the COC.

Synthesis and structural analysis of some podands with C 3 symmetry

The multistep syntheses of C3-symmetrical tripodands with terminal triple bonds or azide groups exhibiting 1,3,5-triarylbenzene and 2,4,6-triaryl-1,3,5-triazine cores are reported herein. The structures of the newly synthesized compounds are su
