Virtual screening-driven discovery of dual 5-HT6/5-HT2A receptor ligands with pro-cognitive properties

A virtual screening campaign aimed at finding structurally new compounds active at 5-HT6R provided a set of candidates. Among those, one structure, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl)amino]methyl}furan-2-yl)phenol (1, 5-HT6R Ki = 91 nM), was selected as a hit for further optimization. As expected, the chemical scaffold of selected compound was significantly different from all the serotonin receptor ligands published to date. Synthetic efforts, supported by molecular modelling, provided 43 compounds representing different substitution patterns. The derivative 42, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl)amino]methyl}furan-2-yl)phenol (5-HT6R Ki = 25, 5-HT2AR Ki = 32 nM), was selected as a lead and showed a good brain/plasma concentration profile, and it reversed phencyclidine-induced memory impairment. Considering the unique activity profile, the obtained series might be a good starting point for the development of a novel antipsychotic or antidepressant with pro-cognitive properties.

Structural modifications to tetrahydropyridine-3-carboxylate esters en route to the discovery of M5-preferring muscarinic receptor orthosteric antagonists

The M5 muscarinic acetylcholine receptor is suggested to be a potential pharmacotherapeutic target for the treatment of drug abuse. We describe herein the discovery of a series of M5-preferring orthosteric antagonists based on the scaffold of 1,2,5,6-tetrahydropyridine-3- carboxylic acid. Compound 56, the most selective compound in this series, possesses an 11-fold selectivity for the M5 over M1 receptor and shows little activity at M2-M4. This compound, although exhibiting modest affinity (Ki = 2.24 muM) for the [3H]N-methylscopolamine binding site on the M5 receptor, is potent (IC50 = 0.45 nM) in inhibiting oxotremorine-evoked [3H]DA release from rat striatal slices. Further, a homology model of human M5 receptor based on the crystal structure of the rat M3 receptor was constructed, and docking studies of compounds 28 and 56 were performed in an attempt to understand the possible binding mode of these novel analogues to the receptor.

A specific fluorescent probe for zinc ion based on thymolphthalein and it’s application in living cells

Many diseases are connected with chemical substances, zinc ion is most important ion in chemical substances, because zinc ion (Zn2+) has been shown extensively involved in various physiological and pathological processes. In this work, thymolphthalein with good biocompatibility was introduced, the probe was constructed with interweaved benzimidazole and phenol from into the fluorophore system, hydroxyl and amino creating a multipoint binding pocket, which zinc can coordinate in a cooperative breaking Excited-State Intramolecular Proton Transfer, ESIPT. The fluorescence of this probe adding Zn2+ showed an obvious ?turn on? in a quick response within 5 s. In addition, the probe had a good selectivity for zinc ion over other analytes. Furthermore, we also studied the fluorescence imaging of probe in the presence of Zn2+ in living A549 cells.

Rhodium(III)-catalyzed C-H activation/annulation with vinyl esters as an acetylene equivalent

The behavior of electron-rich alkenes in rhodium-catalyzed C-H activation/annulation reactions is investigated. Vinyl acetate emerges as a convenient acetylene equivalent, facilitating the synthesis of sixteen 3,4-unsubstituted isoquinolones, as well as select heteroaryl-fused pyridones. The complementary regiochemical preferences of enol ethers versus enol esters/enamides is discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C9H6O3, you can also check out more blogs about496-41-3

Control Strategy for the Manufacture of Brivanib Alaninate, a Novel Pyrrolotriazine VEGFR/FGFR Inhibitor

This manuscript describes the control strategy for the commercial process to manufacture brivanib alaninate. The active pharmaceutical ingredient is a prodrug which is susceptible to hydrolysis. In addition to controlling hydrolysis, a robust strategy was required in order to control input and process-related impurities. Three significant aspects of control include understanding of the reaction parameters in order to minimize the regioisomer during the alkylation with (R)-propylene oxide, development of a design space through statistical models to control impurity formation, and the use of in situ FT-IR to monitor the hydrogenolysis of the Cbz protecting group.

Structural studies on cycloadducts of furan, 2-methoxyfuran, and 5-trimethylsilylcyclopentadiene with maleic anhydride and N-methylmaleimide

(Chemical Equation Presented) The early stages of the retro-Diels-Alder reaction are clearly apparent in the structures of the cycloadducts formed between furan or 5-trimethylsilylcyclopentadiene with maleic anhydride and N-methylmaleimide. The degree of lengthening of the C-C bonds that break in this reaction is clearly related to the known reactivity of these cycloadducts toward this reaction. In the structures of the cycloadducts 21 and 22 derived from 2-methoxyfuran, the early stages of an alternative fragmentation reaction are apparent, consistent with the reactivity of these compounds in solution.
