Saccharide recognition-induced transformation of pyridine-pyridone alternate oligomers from self-dimer to helical complex

(Chemical Equation Presented) Co-oligomers involving (1H)-4-pyridone and 4-alkoxypyridine rings were studied, and it was found that their supramolecular transformation was caused by saccharide recognition. In the co-oligomers, pyridone and pyridine rings are alternately linked at their 2,6-position with an acetylene bond. The pyridine rings behave as a hydrogen bonding acceptor, and the pyridone rings and tautomerized 4-pyridinol work as a donor. Pyridine-pyridone-pyridine 3-mer was found to self-dimerize on the basis of vapor pressure osmometry in CHCl3, and the association constant was obtained as 2.3 ¡Á 103 M-1 by 1H NMR titration. Longer 5-, 7-, 9-, and 11-mer oligomers showed considerable broadening and anisotropy in the 1H NMR spectra due to self-association. These longer oligomers recognized octyl beta-D- glucopyranoside and changed their form into a chiral helical complex, showing characteristic circular dichroism.

First synthesis of caerulomycin B. A new synthesis of caerulomycin C.

Caerulomycins produced by Streptomyces caeruleus are bipyridinic molecules endowed with antibiotic properties. The first synthesis of caerulomycin B (1) as well as a new synthesis of caerulomycin C (2) are reported. Starting from 3-hydroxypyridine, the same methodology was used to prepare both compounds 1 and 2. Efficiently controlled reactions such as metalation to allow the synthesis of 2,6-diiodo-3,4-dialkoxypyridines, which are key intermediates, and further halogen-lithium exchange and cross-coupling to reach the targets molecules 1 and 2 have been developed.

TMP-magnesium and TMP-Zinc bases for the regioselective metalation of the cinnoline scaffold

A regioselective functionalization of cinnolines in positions 3 and 8 using metalations has been developed. This involves either the use of a frustrated Lewis pair consisting of BF3¡¤Et2O and TMP 2Mg¡¤2LiCl or the in situ generated base TMP 2Zn¡¤2MgCl2¡¤2LiCl. Successive metalations allow the preparation of 3,8-disubstituted cinnolines. Various functionalizations by acylation, allylation, and cross-coupling reactions with aryl halides or alkenyl iodides were carried out successfully.

A Unique Approach to Design Potent and Selective Cyclic Adenosine Monophosphate Response Element Binding Protein, Binding Protein (CBP) Inhibitors

The epigenetic regulator CBP/P300 presents a novel therapeutic target for oncology. Previously, we disclosed the development of potent and selective CBP bromodomain inhibitors by first identifying pharmacophores that bind the KAc region and then building into the LPF shelf. Herein, we report the “hybridization” of a variety of KAc-binding fragments with a tetrahydroquinoline scaffold that makes optimal interactions with the LPF shelf, imparting enhanced potency and selectivity to the hybridized ligand. To demonstrate the utility of our hybridization approach, two analogues containing unique Asn binders and the optimized tetrahydroquinoline moiety were rapidly optimized to yield single-digit nanomolar inhibitors of CBP with exquisite selectivity over BRD4(1) and the broader bromodomain family.

SOME REACTIONS OF 3-HALOGENOCINNOLINES CATALYSED BY PALLADIUM COMPOUNDS

3-Bromo-or 3-iodo-cinnoline (and 4-substituted analogues ) are condensed with terminal alkynes in the presence of Pd and Cu compounds as catalysts to give the 3-alkynyl-derivatives.When 4-chloro- or 4-phenoxy-compounds are used, the products react with amines, in the presence of copper(I) iodide, to form pyrrolo<3,2-c>cinnolines and with hydrazines to give either the same ring system or a pyrazolo<4,3-c>cinnoline.Hydrolysis of 3-alkynyl-4phenoxycinnoline to 3-alkynyl-4(1H)-cinnolinone, followed by cyclisation, yields the furo<3,2-c>cinnoline.Attempts to condense 3-halogenocinnolines with alkenes gave variable results: 3-phenyl ethenyl- and 3(2-pyridylethenyl)-4-(1H)-cinnolinones were obtained but 3-bromocinnoline gave the 3,3′-bicinnolinyl.Action of palladium acetate in the presence of ethyl acrylate converted 3-bromo-4-phenoxycinnoline into benzofuro<3,2-c>cinnoline and 3-bromo-4-phenylaminocinnoline into indolo<3,2-c>cinnoline.

New efficient method for the synthesis of chiral 2,2?-bipyridyl ligands

An efficient preparation of chiral 2,2?-bipyridines was developed. Compound 1 was synthesized in 54% yield for three steps starting from 2,6-dibromopyridine. In this synthesis, only catalytic amounts of metals were used in the asymmetric reduction and homo-coupling reaction steps. The total yield and simplicity of experimental procedures were much improved compared with those of the previous report. Other chiral 2,2?-bipyridines were similarly synthesized with high efficiency.
