The scope of catalytic asymmetric hydroboration/oxidation with rhodium complexes of 1,1′-(2-diarylphosphino-1-naphthyl)isoquinolines

Preformed cationic Rh complexes of the title ligands are effective for the asymmetric hydroboration/oxidation of vinylarenes at ambient temperature. These vinylarenes may carry E- or Z-beta substituents but not a substituents. Enantiomer excesses of up to 97% can be obtained in the most favourable cases. The enantioselectivity is moderately sensitive to the structure of the ligand: the difurylphosphino ligand gave superior results for electron-poor styrenes and the diphenylphosphino ligand the best results for electron-rich reactants. Mechanistic aspects are discussed.

Facial synthesis of sulfinic esters via copper-catalyzed reaction of sulfonyl hydrazides with alcohols in air

The efficient Cu-catalyzed esterification of sulfonyl hydrazides with alcohols in air is described, providing sulfinic esters in good yields and broad scope. Mechanistic studies suggest that the reaction likely proceeds through free-radical formation including arylthio radical and arylsulfonyl radical, while arylsulfuric acid are the major esterification intermediate in this transformation.

Synthesis and structure-activity relationships of novel phenoxyacetamide inhibitors of the Pseudomonas aeruginosa type III secretion system (T3SS)

The increasing prevalence of drug-resistant bacterial infections is driving the discovery and development not only of new antibiotics, but also of inhibitors of virulence factors that are crucial for in vivo pathogenicity. One such virulence factor is the type III secretion system (T3SS), which plays a critical role in the establishment and dissemination of Pseudomonas aeruginosa infections. We have recently described the discovery and characterization of a series of inhibitors of P. aeruginosa T3SS based on a phenoxyacetamide scaffold. To better characterize the factors involved in potent T3SS inhibition, we have conducted a systematic exploration of this structure, revealing several highly responsive structure-activity relationships indicative of interaction with a specific target. Most of the structural features contributing to potency were additive, and combination of those features produced optimized inhibitors with IC50 values <1 muM.

1-(Arylalkyl)quinolizidine Derivatives and Thio-Isosteric Analogues as Ligands for Sigma Receptors

A set of 1-(arylalkyl)quinolizidines, isosteric thioanalogues, and variously functionalized congeners were synthesized (see 1-25) and tested for affinity to sigma 1 and sigma 2 receptor subtypes, by displacing [ 3H]- (+)-pentazocine and [3H]DTG from guinea pig brain and rat brain preparations, respectively. All compounds exhibited a good affinity for the sigma1 subtype, with subnanomolar Ki values for the best of them, while only modest or poor affinity for the sigma2 subtype was observed (Tables 1 and 2). Some structure-activity relationships were put forward.

Synthesis and in vitro affinities of various MDL 100907 derivatives as potential 18F-radioligands for 5-HT2A receptor imaging with PET

Radiolabelled piperidine derivatives such as [11C]MDL 100907 and [18F]altanserin have played an important role in diagnosing malfunction in the serotonergic neurotransmission. A variety of novel piperidine MDL 100907 derivatives, possible to label with 18F-fluorine, were synthesized to improve molecular imaging properties of [11C]MDL 100907. Their in vitro affinities to a broad spectrum of neuroreceptors and their lipophilicities were determined and compared to the clinically used reference compounds MDL 100907 and altanserin. The novel compounds MA-1 (53) and (R)-MH.MZ (56) show Ki-values in the nanomolar range towards the 5-HT2A receptor and insignificant binding to other 5-HT receptor subtypes or receptors. Interestingly, compounds MA-1 (53), MH.MZ (55) and (R)-MH.MZ (56) provide a receptor selectivity profile similar to MDL 100907. These compounds could possibly be preferable antagonistic 18F-tracers for visualization of the 5-HT2A receptor status. Medium affine compounds (VK-1 (32), (51), (52), (54)) were synthesized and have Ki values between 30 and 120 nM. All promising compounds show log P values between 2 and 3, that is, within the range of those for the established radiotracers altanserin and MDL 100907. The novel compounds MA-1 (53) and (R)-MH.MZ (56) thus appear to be promising high affine and selective tracers of 18F-labelled analogues for 5-HT2A imaging with PET.

Discovery, synthesis, and structure-activity relations of 3,4-dihydro-1H-spiro(naphthalene-2,2?-piperidin)-1-ones as potassium-competitive acid blockers

With the aim to discover a gastric antisecretory agent more potent than the existing proton pump inhibitors, novel 3,4-dihydro-1H-spiro(naphthalene-2,2?-piperidin)-1-one derivatives, which could occupy two important lipophilic pockets (described as LP-1 and LP-2) of H+,K+-ATPase and can strongly bind to the K+-binding site, were designed based on a docking model. Among the compounds synthesized, compound 4d showed a strong H+,K+-ATPase-inhibitory activity and a high stomach concentration in rats, resulting in potent inhibitory action on histamine-stimulated gastric acid secretion in rats. Furthermore, 4d exerted significant inhibitory action on histamine-stimulated gastric-acid secretion in rats with a rapid onset and moderate duration of action after the administration. These findings may lead to a new insight into the drug design of potassium-competitive acid blockers.
