The synthesis and pharmacol. activity of a new series of 4-alkyl-1-oxa-4,9-diazaspiro[5.5]undecane derivatives as potent dual ligands for the 锜?sub>1 receptor (锜?sub>1R) and the 娓?opioid receptor (MOR) are reported. A lead optimization program over the initial 4-aryl analogs provided 4-alkyl derivatives with the desired functionality and good selectivity and ADME profiles. Compound I (EST73502) showed MOR agonism and 锜?sub>1R antagonism and a potent analgesic activity, comparable to the MOR agonist oxycodone in animal models of acute and chronic pain after single and repeated administration. Contrary to oxycodone, I produces analgesic activity with reduced opioid-induced relevant adverse events, like intestinal transit inhibition and naloxone-precipitated behavioral signs of opiate withdrawal. These results provide evidence that dual MOR agonism and 锜?sub>1R antagonism may be a useful strategy for obtaining potent and safer analgesics and were the basis for the selection of I as a clin. candidate for the treatment of pain. In the experiment, the researchers used many compounds, for example, 2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7Formula: C7H9Br2N).

2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Formula: C7H9Br2N

Selective sp³ C-H alkylation via polarity-match-based cross-coupling was written by Le, Chip;Liang, Yufan;Evans, Ryan W.;Li, Ximing;MacMillan, David W. C.. And the article was included in Nature (London, United Kingdom) in 2017.Computed Properties of C7H9Br2N This article mentions the following:

The functionalization of carbon-hydrogen (C-H) bonds is one of the most attractive strategies for mol. construction in organic chem. The hydrogen atom is considered to be an ideal coupling handle, owing to its relative abundance in organic mols. and its availability for functionalization at almost any stage in a synthetic sequence. Although many C-H functionalization reactions involve C(sp³)-C(sp²) coupling, there is a growing demand for C-H alkylation reactions, wherein sp³ C-H bonds are replaced with sp³ C-alkyl groups. Here, we describe a polarity-match-based selective sp³ C-H alkylation via the combination of photoredox, nickel and hydrogen-atom transfer catalysis. This methodol. simultaneously uses three catalytic cycles to achieve hydridic C-H bond abstraction (enabled by polarity matching), alkyl halide oxidative addition, and reductive elimination to enable alkyl-alkyl fragment coupling. The sp³ C-H alkylation is highly selective for the α-C-H of amines, ethers and sulfides, which are commonly found in pharmaceutically relevant architectures. This cross-coupling protocol should enable broad synthetic applications in de novo synthesis and late-stage functionalization chem. In the experiment, the researchers used many compounds, for example, 2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7Computed Properties of C7H9Br2N).

2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Computed Properties of C7H9Br2N
