Studies on a novel, potent and orally effective cholecystokinin A antagonist, FK-480. Synthesis and structure-activity relationships of FK-480 and related compounds

We prepared various novel tricyclic 1,4-benzodiazepine derivatives as cholecystokinin (CCK) A antagonists, which were evaluated preliminarily for inhibition of 125I-CCK-8 binding to rat pancreatic membranes in vitro and inhibiting effect on CCK-8-induced inhibition of charcoal meal gastric emptying in mice. On the basis of structure-activity relationship (SAR) studies, as well as the stability and availability of the starting materials of those compounds, (S)-N-[1-(2-fluorophenyl)-3,4,6,7-tetrahydro-4-oxo-pyrrolo[3,2,1-jk][1 ,4]benzodiazepin-3-yl]1 H-indole-2-carboxamide (9f, FK-480) was selected as a candidate compound for further evaluation. The absolute configuration of the precursor of FK-480, (3S)-amino-1,4-benzodiazepine derivative ((S)-8a, R1 = F) was determined by an X-ray crystallographic study of its ureido derivative with (S)-alpha-methylbenzyl isocyanate. FK-480 is now undergoing clinical studies for the treatment of chronic pancreatitis.

Regioselective decarboxylative cross-coupling of carboxy isoquinoline N -oxides

A straightforward method for direct decarboxylative arylation of 1- and 3-carboxy isoquinaldic acid N-oxides with aryl iodides is reported. The reaction proceeded selectively at the carboxy function site to exclusively give the corresponding C-1 or C-3 arylated product. This methodology tolerates various aryl iodides substituted by electronically different groups. Combined with subsequent Reissert-Henze chlorination and SNAr amination, the decarboxylative arylation provides an efficient access to 1,3-functionalized isoquinoline-based antitumor agent.

C2-Alkenylation of N-heteroaromatic compounds: Via Br¡ãnsted acid catalysis

Substituted heteroaromatic compounds, especially those based on pyridine, hold a privileged position within drug discovery and medicinal chemistry. However, functionalisation of the C2 position of 6-membered heteroarenes is challenging because of (a) the difficulties of installing a halogen at this site and (b) the instability of C2 heteroaryl-metal reagents. Here we show that C2-alkenylated heteroaromatics can be accessed by simple Br¡ãnsted acid catalysed union of diverse heteroarene N-oxides with alkenes. The approach is notable because (a) it is operationally simple, (b) the Br¡ãnsted acid catalyst is cheap, non-toxic and sustainable, (c) the N-oxide activator disappears during the reaction, and (d) water is the sole stoichiometric byproduct of the process. The new protocol offers orthogonal functional group tolerance to metal-catalysed methods and can be integrated easily into synthetic sequences to provide polyfunctionalised targets. In broader terms, this study demonstrates how classical organic reactivity can still be used to provide solutions to contemporary synthetic challenges that might otherwise be approached using transition metal catalysis.

N-Methylquinolinium derivatives for photonic applications: Enhancement of electron-withdrawing character beyond that of the widely-used N-methylpyridinium

A series of pi-conjugated styryl quinolinium push-pull chromophores have been designed and synthesized in order to examine the electron-withdrawing strength of various quinolinium electron acceptor groups, and their influence on the photophysical properties and in particular on the second-order nonlinear optical response. The static molecular first hyperpolarizabilities measured by long-wavelength hyper-Rayleigh scattering are found to follow the order of the electron withdrawing strength of their acceptor groups as determined by NMR analysis. The quinolinium chromophores based on the strongest electron acceptor groups (1,2- and 1,4-dimethylquinolinium) exhibit remarkably large first hyperpolarizability values of 233 and 256 ¡Á 10-30esu respectively, which is higher than that of the well-known and widely-used pyridinium analogue 4-(4-(dimethylamino)styryl)-1-methylpyridinium 4-methylbenzenesulfonate with first hyperpolarizability = 183 ¡Á 10-30esu. The dimethylquinolinium electron acceptor groups exhibit increased electron-withdrawing strength compared to the dimethylpyridinium group used in 4-(4-(dimethylamino)styryl)-1-methylpyridinium 4-methylbenzenesulfonate, and therefore have a high potential for photonic applications.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C10H9N, you can also check out more blogs about1125-80-0

To elucidate the structural, spectroscopic and bonding properties, the theoretical calculations at the DFT level were undertaken for 1, 3, 5 and 7. The synthesized complexes exhibited moderate activity in the oxidation of 1-phenylethanol and certain alkanes (n-heptane and methylcyclohexane) with tert-butyl hydroperoxide (TBHP) in acetonitrile. Chromatograms of products obtained from the alkanes indicated that a sufficient sterical hindrance exists around of the rhenium catalytic center.
