(–)-cis-N-Normetazocine represents a rigid scaffold able to mimic the tyramine moiety of endogenous opioid peptides, and the introduction of different N-substituents influences affinity and efficacy of respective ligands at MOR (mu opioid receptor), DOR (
Synthesis of new tricyclic 5,6-dihydro-4H-benzo[b][1,2,4]tri-azolo[1,5-d][1,4]diazepine derivatives by [3+ + 2]-cyclo-addition/rearrangement reactions

Two new series of tricyclic heterocycles, namely 5,6-dihydro-4H-benzo[b][1,2,4]triazolo[1,5-d][1,4]diazepinium salts 10 and the related neutral, free bases 13 were synthesized from 4-acetoxy-1-acetyl-4-phenylazo-1,2,3,4-tetrahydroquinolines 8 and nitriles 9 in the presence of aluminium chloride by the [3+ + 2]-cycloaddition reaction of the in situ generated azocarbenium intermediates 14 followed by a ring-expansion rearrangement. In the rearrangement reaction, the phenyl substituent in the initially formed spiro-triazolium adducts 16 underwent a [1,2]-migration from C(3) to the electron-deficient N(2). This led to the ring expansion from 6-membered piperidine to 7-membered diazepine furnishing the tricyclic 1,2,4-triazole-fused 1,4-benzodiazepines.
Formation of acridones by ethylene extrusion in the reaction of arynes with β-lactams and dihydroquinolinones
Fang, Yuesi,Rogness, Donald C.,Larock, Richard C.,Shi, Feng
experimental part, p. 6262 - 6270 (2012/09/22)
N-Unsubstituted β-lactams react with a molecule of aryne by insertion into the amide bond to form a 2,3-dihydroquinolin-4-one, which subsequently reacts with another molecule of aryne to form an acridone by extrusion of a molecule of ethylene. 2,3-Dihydroquinolin-4-ones react under the same reaction conditions to afford identical results. This is the first example of ethylene extrusion in aryne chemistry.
Chroman and tetrahydroquinoline ureas as potent TRPV1 antagonists
Schmidt, Robert G.,Bayburt, Erol K.,Latshaw, Steven P.,Koenig, John R.,Daanen, Jerome F.,McDonald, Heath A.,Bianchi, Bruce R.,Zhong, Chengmin,Joshi, Shailen,Honore, Prisca,Marsh, Kennan C.,Lee, Chih-Hung,Faltynek, Connie R.,Gomtsyan, Arthur
scheme or table, p. 1338 - 1341 (2011/04/23)
Novel chroman and tetrahydroquinoline ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that aryl substituents on the 7- or 8-position of both bicyclic scaffolds imparted the best in vitro potency at TRPV1. The most potent chroman ureas were assessed in chronic and acute pain models, and compounds with the ability to cross the blood-brain barrier were shown to be highly efficacious. The tetrahydroquinoline ureas were found to be potent CYP3A4 inhibitors, but replacement of bulky substituents at the nitrogen atom of the tetrahydroisoquinoline moiety with small groups such as methyl can minimize the inhibition.
Design, synthesis and biological evaluation of hydroxamic acid derivatives as potential high density lipoprotein (HDL) receptor CLA-1 up-regulating agents

experimental part, p. 9178 - 9193 (2012/01/12)
Trichostatin A (TSA) and suberoylanilide hydroxamic acid (SAHA) were reported in our recent publication as novel human high density lipoprotein (HDL) receptor CD36 and Lysosomal integral membrane protein-II Analogous-1 (CLA-1) up-regulators. As part of a
Synthesis and biological evaluation of a new series of berberine derivatives as dual inhibitors of acetylcholinesterase and butyrylcholinesterase
Huang, Ling,Luo, Zonghua,He, Feng,Lu, Jing,Li, Xingshu
experimental part, p. 4475 - 4484 (2010/08/22)
A series of novel berberine derivatives were designed, synthesized, and biologically evaluated as inhibitors of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among these derivatives, compound 48a, berberine linked with 3-methylpyridi
Rapid assembly and in situ screening of bidentate inhibitors of protein tyrosine phosphatases
Srinivasan, Rajavel,Uttamchandani, Mahesh,Yao, Shao Q.
, p. 713 - 716 (2007/10/03)
We have successfully designed and synthesized a small library of protein tyrosine phosphatase (PTP) inhibitors, in which the so-called "click chemistry" or Cu(I)-catalyzed 1,3-dipolar alkyne-azide coupling reaction was carried out for rapid assembly of 66 different bidentate compounds. Subsequent in situ enzymatic screening revealed a potential PTP1B inhibitor (IC50 = 4.7 μM) which is 10-100 fold more potent than other PTPs.
Synthesis of some substituted pyrazinopyridoindoles and 3D QSAR studies along with related compounds: Piperazines, piperidines, pyrazinoisoquinolines, and diphenhydramine, and its semi-rigid analogs as antihistamines (H1)

3D QSAR studies on the title compounds led to the development of a model with three biophoric sites and six secondary sites viz. H-acceptor (ACC), H-donor (DON), heteroatom (presence), hydrophobic (hydrophobicity), steric (refractivity), and a ring (prese

Synthesis of 1-[ω-[(arylamino)carbonyl]alkyl]-4-(benzocycloalkyl)piperazines

, p. 723 - 734 (2007/10/03)
A series of 1-[co-[(arylamino)carbonyl]alkyl]-4-(benzocycloalkyl)-piperazines (1a-v) was prepared either by reacting the precursor 4-[ω-[(arylamino)carbonyl]alkyl]piperazine (2a-j) with 1-chlorobenzocycloalkanes (3a-c) (Procedure A) or by reacting the N-aryl-ω-chloroalkanamides (5a-j) with the 4-(benzocycloalkyl)piperazines (10a-c) (Procedure B). The best yields were obtained using procedure A.
