Design and DNA binding of an extended triple-stranded metallo-supramolecular cylinder.

Carsten Uerpmann et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 11(6), 1750-1756 (2005-01-26)

A new tetracationic triple-stranded supramolecular cylinder is prepared from a bis(pyridylimine) ligand containing a diphenylmethane and two ketimine groups in the spacer. The cylinder is longer and slightly wider than the corresponding cylinder containing just diphenylmethane spacers. Inter-strand CH...pi interactions

Rotationally resolved studies of S0 and the exciton coupled S1/S2 origin regions of diphenylmethane and the d(12) isotopologue.

Jaime A Stearns et al.

The Journal of chemical physics, 129(22), 224305-224305 (2008-12-17)

Rotationally resolved microwave and ultraviolet spectra of jet-cooled diphenylmethane (DPM) and DPM-d(12) have been obtained in S(0), S(1), and S(2) electronic states using Fourier-transform microwave and UV laser/molecular beam spectrometers. The S(0) and S(1) states of both isotopologues have been

Vibronic coupling in asymmetric bichromophores: theory and application to diphenylmethane.

Ben Nebgen et al.

The Journal of chemical physics, 137(8), 084112-084112 (2012-09-04)

The theory for modeling vibronic interactions in bichromophores was introduced in sixties by Witkowski and Moffitt [J. Chem. Phys. 33, 872 (1960)] and extended by Fulton and Gouterman [J. Chem. Phys. 35, 1059 (1961)]. The present work describes extension of

Structural similitudes between cytotoxic antiestrogen-binding site (AEBS) ligands and cytotoxic sigma receptor ligands. Evidence for a relationship between cytotoxicity and affinity for AEBS or sigma-2 receptor but not for sigma-1 receptor.

B Kedjouar et al.

Biochemical pharmacology, 58(12), 1927-1939 (1999-12-11)

1-Benzyl-4-(N-2-pyrrolidinylethoxy)benzene (PBPE) is a cytotoxic derivative of the antitumoral drug tamoxifen. PBPE binds with high-affinity and specificity to the microsomal antiestrogen-binding site (AEBS). PBPE, as well as some other high-affinity AEBS ligands, shares structural features with high-affinity and selective sigma

Palladium-catalyzed cross-coupling reactions of benzyl indium reagents with aryl iodides.

Louis S Chupak et al.

The Journal of organic chemistry, 74(3), 1388-1390 (2008-12-23)

Herein described is an operationally simple procedure for generating benzyl indium species from readily available benzyl bromides and indium metal followed by in situ palladium-catalyzed coupling with aryl halides. The procedure provides diarylmethanes in modest to excellent yield and tolerates
