The synthesis of compounds 6, 7a,b, 8a,b, 9a,b, and 10a,b where the amino -NH- group of JDTic (3) was replaced with an aromatic – CH-, CH2, O, S, or SO group was accomplished and used to further characterize the SAR of the compound 3 class of kappa opioid receptor antagonists. All of the compounds showed subnanomolar to low nanomolar Ke values at the kappa opioid receptor. The most potent compound was 7a, where the amino -NH- group of 3 was replaced by a methylene (-CH2-) group. This compound had a K e = 0.18 nM and was 37- and 248-fold selective for the kappa relative to the mu and delta opioid receptors, respectively. Similar to compound 3, compound 7a antagonized selective kappa agonist U50,488-induced diuresis after sc administration in rats. In contrast to 3, where kappa antagonist activity lasted for three weeks, compound 7a did not show any kappa antagonist activity after one week.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 254-60-4, 1,8-Diazanaphthalene, introducing its new discovery.

A series of gold(I) complexes [Au(PPh3)L]ClO4 (L = pyridine 1a, 2,6-dimethylpyridine 1b, 2,6-di-tert-butylpyridine 1c, quinoline 1d, acridine 1e, benzo[h]quinoline 1f, naphthyridine 2a, 1,10-phenanthroline 2b, 2,2?-biquinoline 2c, di-2-pyridyl ketone 2d, di-2-pyridylamine 3a or 2-(2-pyridyl)benzimidazole 3b) were prepared by reaction of L with [Au(PPh3)(ClO4)] which was synthesized in situ. All complexes were characterized by IR, UV/VIS and 1H NMR spectroscopy. The crystal and molecular structures of 1b, 2a and 3b were investigated by single-crystal X-ray diffraction techniques. The gold(I) is co-ordinated to one nitrogen atom and one phosphine atom. Detailed 1H NMR studies suggested that linear two-co-ordinated structures persist in solution and further that all the complexes [Au(PPh3)L]ClO4, (2a-2d), are fluxional species in which the co-ordination site of gold(I) rapidly exchanges between two nitrogen atoms of the ligand.

A pragmatic approach for preparing glycoconjugates of complex oligosaccharides is to prepare the oligosaccharide as a building block with most of its protecting groups exchanged to protecting groups whose cleavage and other manipulations are highly compatible with the functional groups of complex aglycones. For such an approach the reducing end sugar of the building bloc must be protected with a cleavable protecting group during the oligosaccharide synthesis. We demonstrate that the acid labile 1-methyl 1?- cyclopropylmethyl (MCPM) can be effectively used for this purpose. A trisaccharide glycolipid and a disaccharide glycoamino acid are prepared. The absolute chirality of the MCPM in one key acceptor is determined by a combination of NMR NOE measurements, DFT molecular modeling and Noyori catalyst catalyzed asymmetric reduction.

The alternating copolymerization of carbon monoxide and olefins is a reaction that transition metal complexes, generally containing palladium, catalyze in different phase variation systems. The polyketone products are not only low cost thermal plastics that can be made but also polymeric materials featured by unique chemical and physical properties. These properties can be finely tuned by an appropriate choice of the catalyst and olefinic comonomer. After introducing the topic, the specific metal catalysts for each type of olefinic substrate are described together with the reaction mechanisms involved.
