Sidique, Shyama published the artcileOrally Active Metabotropic Glutamate Subtype 2 Receptor Positive Allosteric Modulators: Structure-Activity Relationships and Assessment in a Rat Model of Nicotine Dependence, SDS of cas: 6797-79-1, the main research area is benzisothiazolone isoindolinone metabotropic glutamate receptor pos allosteric modulator preparation; structure activity relationship mGlu2 receptor modulator treatment nicotine dependence.

Compounds that modulate metabotropic glutamate subtype 2 (mGlu2) receptors have the potential to treat several disorders of the central nervous system (CNS) including drug dependence. Herein the authors describe the synthesis and structure-activity relationship (SAR) studies around a series of mGlu2 receptor pos. allosteric modulators (PAMs). The effects of N-substitution and substitutions on the aryl ring were identified as key areas for SAR exploration. Investigation of the effects of varying substituents in both the isoindolinone (I) and benzisothiazolone (II) series led to compounds with improved in vitro potency and/or efficacy. In addition, several analogs exhibited promising pharmacokinetic (PK) properties. Furthermore, compound I was shown to dose-dependently decrease nicotine self-administration in rats following oral administration. Our data, showing for the first time efficacy of an mGlu2 receptor PAM in this in vivo model, suggest potential utility for the treatment of nicotine dependence in humans.

The use of a frustrated Lewis pair derived from cinnoline, BF3·Et2O, and TMP2Mg·2LiCl yielded 3-substituted cinnolines while the use of the in situ-generated base TMP2Zn·2MgCl2·2LiCl yielded 8-substituted cinnolines; successive metalations allowed the preparation of 3,8-disubstituted cinnolines.

Deng, Guanghui published the artcileNovel complex crystal structure of prolyl hydroxylase domain-containing protein 2 (PHD2): 2,8-Diazaspiro[4.5]decan-1-ones as potent, orally bioavailable PHD2 inhibitors, Related Products of chlorides-buliding-blocks, the main research area is crystal structure prolyl hydroxylase domain protein diazaspirodecanone; 2,8-Diazaspiro[4.5]decan-1-one; Hypoxia inducible factor (HIF); PHD inhibitors; PHD2 crystal structure; Prolyl hydroxylase domain-containing protein 2 (PHD2); SAR study.

We have discovered a novel complex crystal structure of the PHD2 enzyme with its inhibitor, the 2,8-diazaspiro[4.5]decan-1-one analog 4b. The widely reported salt bridge between Arg383 of the enzyme and its inhibitors in all complex structures published thus far was not observed in our case. In our complex structure compound 4b forms several novel interactions with the enzyme, which include a hydrogen bond with Arg322, a π-cation interaction with Arg322, a π-π stacking with Trp389, and a π-π stacking with His313. Guided by the structural information, SAR studies were performed on the 2,8-diazaspiro[4.5]decan-1-one series leading to the discovery of compound 9p with high potency and good oral pharmacokinetic profile in mice.

Pytlarczyk, Marta published the artcileNematic stability of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls and its deuterated isotopologue, Safety of 4-Chloro-2-fluoroiodobenzene, the main research area is alkylphenyl boronic acid chlorotrifluoro biphenyl palladium SPhos catalyst coupling; trifluoro alkyl terphenyl preparation.

In this work, three synthetic methodologies of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls were presented. The most convenient synthetic method was used for homologous series of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls (alkyl chain from Me to hexyl). The results showed that fluorination in the inner-core position (at 2 and 2′ position of terphenyl core) promoted only a nematic phase. The results was discussed with other chloro- and fluoro- substituted 4”-alkyl-[1,1′:4′,1”]terphenyls and one perdeuterated terphenyl analog. The synthesis and purity of synthesized compounds were monitored by gas chromatog. GC-MS, GC-FID and by thin layer chromatog. (TLC). The phase situation and the phase transition temperatures were determined by polarized optical microscopy (POM). The temperatures and enthalpies of the phase transitions were measured by using differential scanning calorimetry (DSC).

A series of 3-(phenoxy-phenyl-methyl)-pyrrolidine analogs were discovered to be potent and balanced norepinephrine (NE) and serotonin (5-hydroxytryptamine, 5-HT) reuptake inhibitors. Several of these compounds were identified to have suitable in vitro pharmacokinetic properties for an orally dosed and CNS-targeted drug. Compound 39b, in particular, was identified as a potent NET and SERT reuptake inhibitor (NSRI) with minimal off-target activity and demonstrated robust efficacy in the spinal nerve ligation model of pain behavior.

Liu, Zhenghui published the artcileSmall organic molecules with tailored structures: initiators in the transition-metal-free C-H arylation of unactivated arenes, Formula: C6H3ClFI, the main research area is biaryl preparation; unactivated arene aryl iodide arylation methylaminophenyl methanol catalyst.

In this article, an optimized catalytically active mol., (2-(methylamino)phenyl)methanol, was designed. A broad range of aryl iodides RI (R = 2-fluorophenyl, thiophen-3-yl, pyridin-4-yl, etc.) could be converted into the corresponding arylated products RR1 (R1 = Ph, 4-methylphenyl) at 100°C over 24 h with good to excellent yields. Mechanistic experiments verified that radicals participated in this catalytic transformation and that the cleavage of the aromatic C-H bond was not the rate determining step. A K+ capture experiment by 18-crown-6 emphasized the significance of the cation species of the strong base. Fourier transform IR spectroscopy proved that the catalytic system was activated by the hydrogen bonds between small organic mols. and tBuOK. Also, a clear mechanism was proposed. This transition-metal-free method affords a promising system for efficient and inexpensive synthesis of biaryls via a user-friendly approach, as confirmed by scale-up experiments

Xu, Yankun published the artcilePalladium/Norbornene Chemistry: Synthesis of Norbornene-Containing Arylsilanes Involving Double C-Si Bond Formation, Computed Properties of 6797-79-1, the main research area is palladium catalyzed three component reaction aryl halide norbornene methyldisilane; methylsilylbiphenyl bicycloheptanylsilane silylnorbornene preparation crystal structure; mol structure methylsilylbiphenyl bicycloheptanylsilane silylnorbornene.

A novel Pd-catalyzed three-component cascade reaction of aryl halides with norbornene and hexamethyldisilane was described, which allows the simultaneous construction of two C-Si bonds and one C-C bond. The method achieves ortho C-H functionalization of aryl halides through the formation of the five-membered palladacycle, leading to norbornene-containing arylsilanes.

Shen, Chaoren published the artcilePalladium-Catalyzed Carbonylative Four-Component Synthesis of Thiochromenones: The Advantages of a Reagent Capsule, Safety of 4-Chloro-2-fluoroiodobenzene, the main research area is four component reaction fluoroiodobenzene phenylacetylene carbonylative palladium catalyst; thiochromenone preparation; carbonylation; multicomponent reactions; palladium catalysis; thiochromenones.

Multicomponent reactions, especially those involving four or even more reagents, have been a long-standing challenge because of the issues associated with balancing reactivity, selectivity, and compatibility. Herein, we demonstrate how the use of a reagent capsule provides straightforward access to synthetically valuable thiochromenone derivatives by a palladium-catalyzed carbonylative four-component reaction. To the best of our knowledge, this is the first example of applying a capsule to prevent catalyst poisoning and undesired side reactions of the multicomponent reaction.
