The authors recently reported the synthesis and biol. activity of the sulfonamide I, the first potent 5-HT7 receptor antagonist with 100-fold selectivity over a wide range of receptors. More recently a series of tetrahydrobenzindoles have been reported as potent 5-HT7 receptor antagonists, although selectivity over 5-HT2 receptors was only 50-fold. In this communication, the authors report the further optimization of I by conformational restraint of the side chain which has led to more potent and selective compounds, exemplified by II. II was evaluated in a functional model of 5-HT7 receptor activation by examination of adenylyl cyclase activity in HEK 293 cells stably expressing the human 5-HT7(a) receptor.

Computed Properties of C10H19NO3. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Boc-D-Prolinol, is researched, Molecular C10H19NO3, CAS is 83435-58-9, about Discovery of 7H-pyrrolo[2,3-d]pyrimidine derivatives as selective covalent irreversible inhibitors of interleukin-2-inducible T-cell kinase (Itk). Author is Tang, Guanghui; Liu, Lihong; Wang, Xueying; Pan, Zhengying.

Interleukin-2-inducible T-cell kinase (Itk) plays an important role in multiple signal transduction pathways in T and mast cells, and is a potential drug target for treating inflammatory diseases, autoimmune diseases, and T cell leukemia/lymphoma. Herein, we describe the discovery of a series of covalent Itk inhibitors based on the 7H-pyrrolo[2,3-d]pyrimidine scaffold. Placing an appropriate substitution group at a hydration site of the ATP binding pocket of Itk and using a saturated heterocyclic ring as a linker to the reactive group were crucial for selectivity. The optimized compound 9 showed potent activity against Itk, excellent selectivity for Itk over Btk and other structurally related kinases, inhibition of phospholipase C-γ1 (PLC-γ1) phosphorylation in cells, and anti-proliferative effects against multiple T leukemia/lymphoma cell lines. Compound 9 can serve as a valuable compound for further determination of functions of Itk.

Recommanded Product: Boc-D-Prolinol. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Boc-D-Prolinol, is researched, Molecular C10H19NO3, CAS is 83435-58-9, about Site-Selective Switching Strategies to Functionalize Polyazines. Author is Dolewski, Ryan D.; Fricke, Patrick J.; McNally, Andrew.

Many drug fragments and therapeutic compounds contain multiple pyridines and diazines. Developing site-selective reactions where specific C-H bonds can be transformed in polyazine structures would enable rapid access to valuable derivatives Authors present a study that addresses this challenge by selectively installing a phosphonium ion as a versatile functional handle. Inherent factors that control site-selectivity are described along with mechanistically driven approaches for site-selective switching, where the C-+PPh3 group can be predictably installed at other positions in the polyazine system. Simple protocols, readily available reagents, and application to complex drug-like mols. make this approach appealing to medicinal chemists.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

A series of 2-(aryloxymethyl)azetidine and -pyrrolidine nAChR ligands in which the 3-pyridyl moiety of a previously described series was replaced by a substituted Ph group was explored. Aromatic substitution afforded analogs with Ki values ranging from 3 to >10,000 nM. Generally, substitution at the ortho- and para-position was unfavorable, whereas electron-withdrawing groups at the meta-position improved the Ki values.

Application In Synthesis of Boc-D-Prolinol. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Boc-D-Prolinol, is researched, Molecular C10H19NO3, CAS is 83435-58-9, about Synthesis and evaluation of in vivo anti-hypothermic effect of all stereoisomers of the thyrotropin-releasing hormone mimetic: Rovatirelin Hydrate. Author is Kobayashi, Naotake; Sato, Norihito; Sugita, Katsuji; Takahashi, Kouji; Sugawara, Tamio; Tada, Yukio; Yoshikawa, Takayoshi.

We discovered the orally active TSH-releasing hormone (TRH) mimetic: (4S,5S)-5-methyl-N-{(2S)-1-[(2R)-2-methylpyrrolidin-1-yl]-1-oxo-3-(1,3-thiazol-4-yl)propan-2-yl}-2-oxo-1,3-oxazolidine-4-carboxamide 1 (rovatirelin). The central nervous system (CNS) effect of rovatirelin after i.v. (iv) administration is 100-fold higher than that of TRH. As 1 has four asym. carbons in its mol., there are 16 stereoisomers. We synthesized and evaluated the anti-hypothermic effect of all stereoisomers of 1, which has the (4S),(5S),(2S),(2R) configuration from the N-terminus to the C-terminus, in order to clarify the structure-activity relationship (SAR) of stereoisomers. The (4R),(5R),(2R),(2S)-isomer 16 did not show any anti-hypothermic effect. Only the (4S),(5S),(2S),(2S)-isomer 10, which has the (2S)-2-methylpyrrolidine moiety at the C-terminus showed the anti-hypothermic effect similar to 1. Stereoisomers, which have the (5R) configuration of the oxazolidinone at the N-terminus and the (2R) configuration at the middle-part, showed a much lower anti-hypothermic effect than that of 1. On the other hand, stereoisomers, which have the (4R) configuration of the oxazolidinone at the N-terminus or the (2S) configuration of the C-terminus, have little influence on the anti-hypothermic effect.

Lithiation of N-Boc-pyrrolidine (I) with sec-butyllithium (s-BuLi)/(-)-sparteine (II) effects an asym. deprotonation to give (S)-2-lithio-N-Boc-pyrrolidine, which reacts with electrophiles to provide the 2-substituted N-Boc-pyrrolidines in enantiomeric excesses which generally are >90%. In the lithiation-silylation of I with the chiral ligand III gives IV with a lower enantiomeric excess. Diastereoselective amplification operates in a sequential lithiation-substitution sequence to provide the conversion of (S)-2-methyl-N-Boc-pyrrolidine of 95% enantiomeric excess with s-BuLi/II to (S,S)-2,5-dimethyl-N-Boc-pyrrolidine ((S,S)-19) with >99% enantiomeric excess. Synthetic preparations of a useful chiral ligand, (R)-α,α-diphenyl-2-pyrrolidine, and a useful chiral auxiliary, (S,S)-2,5-dimethylpyrrolidine hydrochloride, are reported. Reactions of racemic and enantioenriched 2-lithio-N-Boc-pyrrolidine and investigation of sequential lithiations-deuterations of I establish the reaction pathway to be asym. deprotonation rather than asym. substitution. A rationalization for the enantioselective deprotonation is provided.

Abreo, Melwyn A.; Lin, Nan-Horng; Garvey, David S.; Gunn, David E.; Hettinger, Anne-Marie; Wasicak, James T.; Pavlik, Patricia A.; Martin, Yvonne C.; Donnelly-Roberts, Diana L. published the article 《Novel 3-Pyridyl Ethers with Subnanomolar Affinity for Central Neuronal Nicotinic Acetylcholine Receptors》.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:83435-58-9) here.

Recent evidence indicating the therapeutic potential of cholinergic channel modulators for the treatment of central nervous system (CNS) disorders as well as the diversity of brain neuronal nicotinic acetylcholine receptors (nAChRs) have suggested an opportunity to develop subtype-selective nAChR ligands for the treatment of specific CNS disorders with reduced side effect liabilities. The synthesis of a novel series of 3-pyridyl ether compounds was reported which possess subnanomolar affinity for brain nAChRs and differentially activate subtypes of neuronal nAChRs. The synthesis and structure-activity relationships for the leading members of the series are described, including A-85380, which possesses ca. 50 pM affinity for rat brain [3H]-(-)-cytisine binding sites and 163% efficacy compared to nicotine to stimulate ion flux at human α4β2 nAChR subtype, and A-84543, which exhibits 84-fold selectivity to stimulate ion flux at human α4β2 nAChR subtype compared to human ganglionic type nAChRs. Computational studies indicate that a reasonable superposition of a low energy conformer of A-85380 with (S)-nicotine and (-)-epibatidine can be achieved. An example compound are (S)-3-[(1-methyl-2-pyrrolidinyl)methoxy]pyridine and (S)-3-(1-methyl-2-azetidinylmethoxy)pyridine.
