, p. 63 - 72 (1998)
A novel photoaffinity probe for the leukotriene D4 receptor (LTD4) is described. L-745310, which is structurally related to the potent LTD4 antagonist MK-0476 (Singulair(TM)), was found to selectively label a 43-kDa protei

Synthesis of terpyridine-based building blocks has allowed the self-assembly of a nanosized metallomacrocycle with precisely positioned, peripheral metal complexes. Construction of the precursors included the assembly of a heteroleptic bisterpyridine-Ru(ii) complex possessing a diiodoaryl moiety that was subsequently reacted with two equivalents of 4′-ethynyl-2, 2′:6′,2′′-terpyridine via a Pd(0)-catalyzed Sonagashira coupling, to generate the requisite monomer with two, 120°-juxtaposed metal coordination sites. Addition of one equivalent of Fe(ii) to one equivalent of the bisligand afforded the metallocycle with 12 metals [6 internal Fe(ii) ions and 6 external Ru(ii) ions] measuring ca. 7 nm in diameter.

experimental part, p. 1498 - 1516 (2010/05/02)
Chemical Equation Presented A series of linear and star-shaped π-conjugated oligomer hybrids (2-5) composed of an oligoyne core, ranging from 1,3-butadiyne to 1,3,5,7,9,11-dodecahexayne, and fullerenyl end-capping groups has been synthesized and studied.
Solid-phase approaches toward cyclic oligomers

Strategies were sought to effect cyclizations of oligo(m-phenylene ethynylene) by exploiting pseudo-high dilution effects on polymer supports. Using Pd/Cu-catalyzed coupling protocols, Merrifield's resin (1% crosslinked chloromethylated polystyrene) proved inadequate for site isolation; inter-site couplings ensued on the flexible support. Conversely, use of the Argopore resin, a more highly crosslinked polystyrene, inhibited inter-site interactions, and no identifiable final product could be separated from the resin. Spectroscopic and mass spectrometric methods indicated that the product from the Argopore resin might be a threaded catenane.

A facile Pd-catalyzed strategy by which multiantennary glycoclusters and sugar dendrons can be readily assembled in one-step is described.
Iodo-aryl carbonates for use in methods in radiography

, (2008/06/13)
A method for using iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, to provide radiopaques for various radiography purposes in connection with such techniques as X-ray applications including myelography, salpingography, lymphography and bronchography. The method first comprises selecting a compound generally categorized as a carbonate and having the general formula STR1 wherein R represents an alkyl group having from 1 to 10 carbon atoms and R' represents an iodinated phenyl linked directly to the ester oxygen or through an alkyl chain consisting of 1 to 3 carbon atoms. An effective amount of a pharmaceutically acceptable carbonate, as defined herein, is then placed into the subject body cavity and the particular X-ray or other study performed of this area.
Iodine containing organic carbonates for use as radiographic agents

Iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, for use as radiographic media in connection with such techniques as x-ray applications including myelography, salpingography, lymphography and bronchography. An effective quantity of iodinated organic carbonate provides x-ray contrast, and the compounds of the invention may be characterized generally as carbonates having the general formula STR1 wherein R represents an alkyl group having from 4 to 10 carbon atoms and R' represents an iodinated phenyl linked to the ester oxygen through an alkyl chain consisting of 1 to 3 carbon atoms.
