Selective acetylcholinesterase inhibitors derived from muscle relaxant dantrolene
Aoyama, Hiroshi,Doura, Tomohiro
, (2020)
Dantrolene, the only therapeutic agent for malignant hyperthermia, is known to have not only a muscle relaxant effect, but also a neuroprotective effect and Alzheimer's disease improving effect. Recently, it has been reported that dantrolene has a weak inhibitory effect on acetylcholinesterase (AChE), which is a therapeutic drug target for Alzheimer's disease. Thus, we focused on developing of AChE inhibitors with benzylpiperidine/piperazine moieties that are based on the dantrolene skeleton. Several derivatives showed an inhibitory activity. Among them, ortho-nitro derivative 8c showed the most potent inhibitory activity with the IC50 value of 34.2 nM. Furthermore, Lineweaver-Burk plot analysis indicated that 8c is AChE-selective inhibitor, which shows only a weak inhibitory effect on butyrylcholinesterase (BuChE) and a non-competitive inhibition.

In this study, we synthesized a series of double-component O2-aryl diazeniumdiolate (DDNO) derivatives, of which each molecule can release up to four nitric oxide molecules. These compounds showed cytotoxic activities to cancer cells, such as human leukemia, breast cancer and lung cancer. Among them, compound 1 (DDNO-1) showed the highest specific activity to human leukemia cells. It induced cell apopotosis and arrest cell cycle of G2/M phase. The JNK and p38 protein kinases were activated by compound 1 to induce cancer cell apoptosis. Compound 1 also increased pro-apoptotic Bax level, which is a same function compared to a reported NO donor, JS-K. More interestingly, it decreased the level of an anti-apoptotic member Bcl-2, which is an opposite effect compared to JS-K. Compound 1 could be developed as a new anti-cancer agent since it increases the Bax/Bcl-2 ratio to overcome the drug resistance.

A series of iodinated ligands for the SPECT imaging of 5-HT4 receptors was designed starting from the previously reported hit MR-26132. We focused on the modulation of the piperidine-containing lateral chain by introducing hydrophilic groups in order to decrease the liphophilicity of the new ligands. All the synthesized compounds were tested for their binding affinities on 5-HT4Rs and based on the Ligand Lipophilicity Efficiency approach, compound 13 was further selected for radioiodination with iodine-125 and imaging experiments. Compound 13 showed its ability to displace the specific signal of the reference compound [125I]SB-207710 but no significant detection of [125I]13 was observed in vivo in SPECT experiments.

Pleiotropic intervention may be a requirement for effective limitation of the progression of multifactorial diseases such as Alzheimer's Disease. One approach to such intervention is to design a single chemical entity capable of acting on two or more targets of interest, which are accordingly known as Multi-Target Directed Ligands (MTDLs). We recently described donecopride, the first MTDL able to simultaneously inhibit acetylcholinesterase and act as an agonist of the 5-HT4 receptor, which displays promising activities in vivo. Pharmacomodulation of donecopride allowed us to develop a novel series of indole derivatives possessing interesting in vitro activities toward AChE and the σ1 receptor. The crystal structures of complexes of the most promising compounds with Torpedo californica AChE were solved in order to further understand their mode of inhibition.
Novel multi target-directed ligands targeting 5-HT4 receptors with in cellulo antioxidant properties as promising leads in Alzheimer's disease

Facing the complexity of Alzheimer's disease (AD), it is now currently admitted that a therapeutic pleiotropic intervention is needed to alter its progression. Among the major hallmarks of the disease, the amyloid pathology and the oxidative stress are closely related. We propose in this study to develop original Multi-Target Directed Ligands (MTDL) able to impact at the same time Aβ protein accumulation and toxicity of Reactive Oxygen Species (ROS) in neuronal cells. Such MTDL were obtained by linking on a central piperidine two scaffolds of interest: a typical aminochlorobenzophenone present in numerous 5-HT4R agonists, and diverse antioxidant chemotypes. Interestingly, the most active compound 9g possesses a Ki of 12.7 nM towards 5-HT4R and an antioxidant activity in vitro and in cellulo.

Stereospecific Synthesis of E-Alkenes through Anti-Markovnikov Hydroalkylation of Terminal Alkynes

supporting information, p. 12464 - 12469 (2019/08/20)
We have developed a method for stereospecific synthesis of E-alkenes from terminal alkynes and alkyl iodides. The hydroalkylation reaction is enabled by a cooperative action of copper and nickel catalysts and proceeds with excellent anti-Markovnikov selectivity. We demonstrate the broad scope of the reaction, which can be accomplished in the presence of esters, nitriles, aryl bromides, ethers, alkyl chlorides, anilines, and a wide range of nitrogen-containing heteroaromatic compounds. Mechanistic studies provide evidence that the copper catalyst activates the alkyne by hydrocupration, which controls both the regio- and diastereoselectivity of the overall reaction. The nickel catalyst activates the alkyl iodide and promotes cross coupling with the alkenyl copper intermediate.
