Potent and selective ET-A antagonists. 1. Syntheses and structure-activity relationships of N-(6-(2-(aryloxy)ethoxy)-4-pyrimidinyl)sulfonamide derivatives

Modifications to the ETA/B mixed type compounds 1 (Ro. 46-2005) and 2 (bosentan) were performed. Introduction of a pyrimidine group into 1 resulted in a dramatic increase in affinity for the ETA receptor, and the subsequent optimization of substituents on the pyrimidine ring led us to the discovery of N-(6-(2-((5-bromo-2-pyrimidinyl)oxy)ethoxy)-5-(4-methylphenyl)- 4pyrimidinyl)-4-tert-butylbenzenesulfonamide (7k), which showed an extremely high affinity for the human cloned ETA receptor (Ki=0.0042¡À0.0038 nM) and an ETA/B receptor selectivity up to 29 000 (Ki=130¡À50 nM for the human cloned ETB receptor). The compound was designed on the hypothesis that the hydrogen atom of the hydroxyl group in 1 and 2 played a role not as a proton donor but as an acceptor in the possible hydrogen bonding with Tyr129. Since the incorporation of a pyrimidinyl group into the hydroxyethoxy side chain of the nonselective antagonist (1) dramatically enhanced both the ETA receptor affinity and selectivity, and since similar results were obtained from the benzene analogues, we put forward the hypothesis that a “pyrimidine binding pocket” might exist in the ETA receptor.

Pyridyl Dicyanoquinodimethane Acceptors for Electroactive Solids

A new synthetic strategy for dicyanoquinodimethane electron acceptors is presented and used to synthesize six such compounds for the first time.The general sequence is substitution of alpha,alpha’-dicyanoxylene alpha anions with electophiles followed by oxidative dehydrogenation.Unlike most previous examples, these quinodimethanes (QDs) are alpha substituted, rather than ring substituted; thus, the substituents increase the aspect ratio of the QDs and extend the ? systems.All contain at least one pyridyl substituent at an alpha position, and the set includes polar, cationic, and phosphonic acid derivatives.The particular compounds were chosen for incorporation into specific types of potentially electroactive solids, although, in principle, the syntheses could accomodate a wide variety of other functional groups.The neutral QD compounds display two reversible reductions, while the cations show single, partially reversible electrochemical transitions.Syn-anti isomerism was noted for several of the QDs, and proton NMR assignments obtained by 2D COSY methods are reported.

On the metalation of 3-substituted and 3,6-disubstituted pyridazines

Metalation, pyradazines, lithiation Starting from 3,6-dichloropyridazine, a series of new pyridazines bearing lithiation-directing groups in alpha-position to a ring nitrogen atom (compounds 1-5) was prepared. Metalation employing lithium alkylamides was found to afford ortho-substituted pyridazines. The regioselectivity, depending on the nature of the metalating agent, is discussed.

Process for preparing N-pyrrolyl-pyridazineamine derivatives

The present invention refers to a new process for preparing N-2,3,4,5-substituted-1H-pyrrol-1-yl)-6-substituted amino-3-pyridazineamine, known as antihypertensive agents. The process is characterized in that a suitable 3,6-dihalogenopyridazine is reacted with hydrazine hydrate or other hydrazine derivatives of formula NH2 NHR, the obtained compound is reacted with a suitable dicarbonyl compound yielding first an alcandione-bis-[6-halogen-3-pyridazininyl]hydrazone, and then a 6-halogen-3-pyrrolylpyridazineamine derivative which is in turn reacted with an amine to yield the desired compounds.

Machine-assisted synthesis of modulators of the histone reader BRD9 using flow methods of chemistry and frontal affinity chromatography

A combination of conventional organic synthesis, remotely monitored flow synthesis and bioassay platforms, were used for the evaluation of novel inhibitors targeting bromodomains outside the well-studied bromodomain and extra terminal (BET) family, here exemplified by activity measurements on the bromodomain of BRD9 protein, a component of some tissue-specific SWi/SNF chromatin remodelling complexes. The Frontal Affinity Chromatography combined with Mass Spectrometry (FAC-MS) method proved to be reliable and results correlated well with an independent thermal shift assay.

Helical self-organization and hierarchical self-assembly of an oligoheterocyclic pyridine-pyridazine strand into extended supramolecular fibers

The synthesis and characterization of an alternating pyridine-pyridazine strand comprising thirteen heterocycles are described. Spontaneous folding into a helical secondary structure is based on a general molecular self-organization process enforced by the conformational information encoded within the primary structure of the molecular strand itself. Conformational control based on heterocyclic “helicity codons” illustrates a strategy for designing folding properties into synthetic oligomers (foldamers). Strong intermolecular interactions of the highly ordered lock-washer subunits of compound 3 results in hierarchical supramolecular self-assembly into protofibrils and fibrils. Compound 3 also forms mechanically stable two-dimensional Langmuir-Blodgett and cast thin films.
