Structure-Activity Study of N -((trans)-4-(2-(7-Cyano-3,4-dihydroisoquinolin-2(1 H)-yl)ethyl)cyclohexyl)-1 H -indole-2-carboxamide (SB269652), a Bitopic Ligand That Acts as a Negative Allosteric Modulator of the Dopamine D2 Receptor

We recently demonstrated that SB269652 (1) engages one protomer of a dopamine D2 receptor (D2R) dimer in a bitopic mode to allosterically inhibit the binding of dopamine at the other protomer. Herein, we investigate structural determinants for allostery, focusing on modifications to three moieties within 1. We find that orthosteric “head” groups with small 7-substituents were important to maintain the limited negative cooperativity of analogues of 1, and replacement of the tetrahydroisoquinoline head group with other D2R “privileged structures” generated orthosteric antagonists. Additionally, replacement of the cyclohexylene linker with polymethylene chains conferred linker length dependency in allosteric pharmacology. We validated the importance of the indolic NH as a hydrogen bond donor moiety for maintaining allostery. Replacement of the indole ring with azaindole conferred a 30-fold increase in affinity while maintaining negative cooperativity. Combined, these results provide novel SAR insight for bitopic ligands that act as negative allosteric modulators of the D2R.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17680-55-6 is helpful to your research. Related Products of 17680-55-6

Doped porous carbon nanostructures with N?Co?O catalytic active sites for efficient electrocatalytic oxygen reduction reaction

A cobalt metal-organic framework constructed by 4-(4-pyridyl)-benzoic acid was used as the precursor to afford a series of Co nanoparticles embedded and N/O-doped porous carbon materials CoNOC-Tc-t (where Tc represents the carbonization temperature and t represents the carbonization time), which possess high surface area, hierarchically micro-, meso- and macropores, and high graphitization as well as the uniformly enchased N?Co?O catalytic active sites derived from pyridine nitrogen atom and chelating carboxylate coordinated octahedral cobalt (II) center. These CoNOC-Tc-t porous carbon nanostructures have demonstrated prominent catalytic activities toward oxygen reduction reaction (ORR) in alkaline medium. Compared with commercial Pt/C catalyst, the CoNOC-800-1 (annealed at 800 C for 1 h) exhibits excellent selectivity via an efficient four-electron-dominant ORR process, as well as the superior durability and methanol tolerance, making it a cost-effective Pt-free ORR electrocatalyst. More importantly, the novelly designed N?Co?O catalytic active sites are proposed and well demonstrated by experiments, which provides a promising approach to develop heteroatom-doped carbon-based electrocatalytic materials.

Synthesis and Preclinical Evaluation of Three Novel Fluorine-18 Labeled Radiopharmaceuticals for P-Glycoprotein PET Imaging at the Blood-Brain Barrier

P-Glycoprotein (P-gp), along with other transporter proteins at the blood-brain barrier (BBB), limits the entry of many pharmaceuticals into the brain. Altered P-gp function has been found in several neurological diseases. To study the P-gp function, many positron emission tomography (PET) radiopharmaceuticals have been developed. Most P-gp radiopharmaceuticals are labeled with carbon-11, while labeling with fluorine-18 would increase their applicability due to longer half-life. Here we present the synthesis and in vivo evaluation of three novel fluorine-18 labeled radiopharmaceuticals: 4-((6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)methyl)-2-(4-fluorophenyl)oxazole (1a), 2-biphenyl-4-yl-2-fluoroethoxy-6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinoline (2), and 5-(1-(2-fluoroethoxy))-[3-(6,7-dimethoxy-3,4-dihydro-1H-isoquinolin-2-yl)-propyl]-5,6,7,8-tetrahydronaphthalen (3). Compounds were characterized as P-gp substrates in vitro, and Mdr1a/b(-/-)Bcrp1(-/-) and wild-type mice were used to assess the substrate potential in vivo. Comparison was made to (R)-[11C]verapamil, which is currently the most frequently used P-gp substrate. Compound [18F]3 was performing the best out of the new radiopharmaceuticals; it had 2-fold higher brain uptake in the Mdr1a/b(-/-)Bcrp1(-/-) mice compared to wild-type and was metabolically quite stable. In the plasma, 69% of the parent compound was intact after 45 min and 96% in the brain. Selectivity of [18F]3 to P-gp was tested by comparing the uptake in Mdr1a/b(-/-) mice to uptake in Mdr1a/b(-/-)Bcrp1(-/-) mice, which was statistically not significantly different. Hence, [18F]3 was found to be selective for P-gp and is a promising new radiopharmaceutical for P-gp PET imaging at the BBB. (Chemical Equation).
