ARRHENIUS parameters have been determined for the solvolysis of a series of acid chlorides of polycyclic aromatic hydrocarbons in methanol-acetone (1:1) (Table 11). The fact that the solvolyses were carried out at an average temperature (275°K)situated above the isokinetic temperature (estimated to be 220°K) explains why the sequence observed is the reverse of the one obtained in the case of the alkaline

A chiral fluorescent receptor 1 based on cholic acid was designed and synthesized. The enantioselective recognition ability of 1 to mandelate anion was studied by the fluorescence in CH3CN and a 1H NMR spectroscopic method. The results indicate that 1 exhibited a good enantioselectivity to the enantiomer of the mandelate anion in CH3CN.

Isoxazole-1,4-dihydropyridines (IDHPs) were tethered to fluorescent moieties using double activation via a lanthanide assisted Weinreb amidation. IDHP-fluorophore conjugate 3c exhibits the highest binding to date for IDHPs at the multidrug-resistance transporter (MDR-1), and IDHP-fluorophore conjugates 3c and 7 distribute selectively in SH-SY5Y cells. A homology model for IDHP binding at MDR-1 is presented which represents our current working hypothesis. (C) 2013 Elsevier Ltd. All rights reserved.
