Exploring Basic Tail Modifications of Coumarin-Based Dual Acetylcholinesterase-Monoamine Oxidase B Inhibitors: Identification of Water-Soluble, Brain-Permeant Neuroprotective Multitarget Agents
Aiming at modulating two key enzymatic targets for Alzheimer's disease (AD), i.e., acetylcholinesterase (AChE) and monoamine oxidase B (MAO B), a series of multitarget ligands was properly designed by linking the 3,4-dimethylcoumarin scaffold to 1,3- and 1,4-substituted piperidine moieties, thus modulating the basicity to improve the hydrophilic/lipophilic balance. After in vitro enzymatic inhibition assays, multipotent inhibitors showing potencies in the nanomolar and in the low micromolar range for hMAO B and eeAChE, respectively, were prioritized and evaluated in human SH-SY5Y cell-based models for their cytotoxicity and neuroprotective effect against oxidative toxins (H2O2, rotenone, and oligomycin-A). The present study led to the identification of a promising multitarget hit compound (5b) exhibiting high hMAO B inhibitory activity (IC50 = 30 nM) and good MAO B/A selectivity (selectivity index, SI = 94) along with a micromolar eeAChE inhibition (IC50 = 1.03 μM). Moreover, 5b behaves as a water-soluble, brain-permeant neuroprotective agent against oxidative insults without interacting with P-gp efflux system.

Design and evaluation of novel piperidine HIV-1 protease inhibitors with potency against DRV-resistant variants
A novel class of HIV-1 protease inhibitors with flexible piperidine as the P2 ligand was designed with the aim of improving extensive interactions with the active subsites. Many inhibitors exhibited good to excellent inhibitory effect on enzymatic activity and viral infectivity. In particular, inhibitor 3a with (R)-piperidine-3-carboxamide as the P2 ligand and 4-methoxybenzenesulfonamide as the P2’ ligand showed an enzyme Ki value of 29 pM and antiviral IC50 value of 0.13 nM, more than six-fold enhancement of activity compared to DRV. Furthermore, there was no significant change in potency against DRV-resistant mutations and HIV-1NL4?3 variant for 3a. Besides, inhibitor 3a exhibited potent antiviral activity against subtype C variants with low nanomole EC50 values. In addition, the molecular modeling revealed important hydrogen bonds and other favorable van der Waals interactions with the backbone atoms of the protease and provided insight for designing and optimizing more potent HIV-1 protease inhibitors.

Radical hydroxymethylation of alkyl iodides using formaldehyde as a C1 synthon
Radical hydroxymethylation using formaldehyde as a C1 synthon is challenging due to the reversible and endothermic nature of the addition process. Here we report a strategy that couples alkyl iodide building blocks with formaldehyde through the use of photocatalysis and a phosphine additive. Halogen-atom transfer (XAT) from α-aminoalkyl radicals is leveraged to convert the iodide into the corresponding open-shell species, while its following addition to formaldehyde is rendered irreversible by trapping the transient O-radical with PPh3. This event delivers a phosphoranyl radical that re-generates the alkyl radical and provides the hydroxymethylated product.

Palladium-catalyzed ring-closing reaction via C-N bond metathesis for rapid construction of saturated N-heterocycles
The ring-closing reactions based on chemical bond metathesis enable the efficient construction of a wide variety of cyclic systems which receive broad interest from medicinal and organic communities. However, the analogous reaction with C-N bond metathesis as a strategic fundamental step remains an unanswered challenge. Herein, we report the design of a new fundamental metallic C-N bond metathesis reaction that enables the palladium-catalyzed ring-closing reaction of aminodienes with aminals. The reactions proceed efficiently under mild conditions and exhibit broad substrate generality and functional group compatibility, leading to a wide variety of 5- to 16-membered N-heterocycles bearing diverse frameworks and functional groups.

Discovery of 2-aminothiazole-4-carboxamides, a novel class of muscarinic M3 selective antagonists, through solution-phase parallel synthesis
Synthesis and structure-activity relationship of a new class of muscarinic M3 selective antagonists were described. In the course of searching for a muscarinic M3 antagonist with a structure distinct from those of the 2-(4,4-difluorocyclopentyl)-2-phenylacetamide derivatives, we identified a thiazole-4-carboxamide derivative (1) as a lead compound in our in-house chemical collection. Since this compound (1) showed relatively low binding affinity (K1 = 140 nM) for M3 receptors in the human binding assays, we tried to improve its potency and selectivity for M 3 over M1 and M2 receptors by derivatization of 1 through a combinatorial approach. A solution-phase parallel synthesis effectively contributed to the optimization of each segment of 1. Thus, we have identified a cyclooctenylmethyl derivative (3e) and a cyclononenylmethyl derivative (3f) as representative M3 selective antagonists in this class.

N-[18F]fluoroethylpiperidin-4ylmethyl acetate, a novel lipophilic acetylcholine analogue for PET measurement of brain acetylcholinesterase activity
The reduction of acetylcholinesterase (AChE) activity in the brain has been measured in dementia disorders such as Alzheimer's disease and dementia with Lewy bodies using 11C-labeled acetylcholine analogues, N-[ 11C]methylpiperidin-4-yl acetate and propionate, and positron emission tomography (PET). Our aim was to develop an 18F-labeled acetylcholine analogue useful for brain AChE mapping with PET, since 18F, with a longer half-life, has advantages over 11C. In a preliminary study, a series of N-[14C]ethylpiperidin-3-yl or -4-ylmethanol esters (acetyl and propionyl esters) were newly designed and evaluated in vitro regarding the reactivity with and specificity to AChE using purified human enzymes, leading to a novel 18F-labeled acetylcholine analogue, N-[18F]fluoroethylpiperidin-4-ylmethyl acetate. In rat experiments, the 18F-labeled candidate showed desirable properties for PET AChE measurement: high brain uptake of the authentic ester, high AChE specificity, a moderate hydrolysis rate, and low membrane permeability (metabolic trapping) of the metabolite.

N-[18F]fluoroethylpiperidin-4-ylmethyl butyrate: A novel radiotracer for quantifying brain butyrylcholinesterase activity by positron emission tomography
In Alzheimer's disease, cerebral cortical butyrylcholinesterase (BChE) activity is reported to be elevated. Our aim was to develop a novel 18F-labeled tracer for quantifying cerebral BChE activity by positron emission tomography. With in vitro screening of N-[14C] ethylpiperidin-3- and 4-ylmethyl esters, N-[14C]ethylpiperidin-4- ylmethyl butyrate was selected as a lead for 18F-labeling, affording N-[18F]fluoroethylpiperidin-4-ylmethyl butyrate. The 18F-labeled butyrate showed the required properties for in vivo BChE measurement, that is, the lipophilic nature of the authentic ester, high specificity to BChE, a moderate hydrolysis rate, and the hydrophilic nature of the metabolite.
