Article Abstract
The triggering receptor expressed on myeloid cells 2 (TREM2) is a lipid-sensing immunoreceptor on microglia that has emerged as a therapeutic target for Alzheimer's disease. Here, we report the discovery of , an achiral structural analog of -the first small molecule TREM2 agonist to enter clinical development. was synthesized via a modular and enantioselective-free route using sequential Suzuki couplings, enabling rapid scaffold diversification. Compared to , the stereochemically simplified derivative ( ) exhibits superior microglial phagocytosis and validated target engagement. induces TREM2 activation in HEK293-hTREM2/DAP12 cells, and its direct binding to TREM2 was confirmed using both microscale thermophoresis (MST) and surface plasmon resonance (SPR). Importantly, also demonstrates a superior pharmacokinetic profile to , including enhanced metabolic stability in human and mouse microsomes, favorable PAMPA permeability, and a LogD . compatible with CNS penetration. Docking studies suggested a potential binding mode of at the extracellular domain of TREM2, revealing key polar and hydrophobic interactions. These findings position as a synthetically accessible and pharmacokinetically favorable lead for the development of TREM2-targeted therapies.

The present study describes the critical achiral and chiral separation of a mixture of azatryptophan derivatives having positional isomers or isobars and their enantiomers, which is successfully achieved using 2D HPLC by employing two different stationary phases and mobile phase combinations in one instrument. The first-dimension experiments were carried out under reversed-phase conditions, where the best separation of racemates was obtained with a Kinetex F5 core-shell column with 10 mM ammonium acetate in water and ACN as a mobile phase in gradient elution mode. The racemate peaks of first dimension experiments were selectively heart-cut based on the time program set in its instrument method and parked in loops for the second-dimension analysis.

For the efficient geometry control of chiral nematic liquid crystals (N*LCs), a variety of chiral furopyran derivatives with three aromatic groups fixed in a pseudo--symmetric fashion was designed as novel chiral dopants (CDs) and successfully synthesized from the alkyne-linked benzofuran systems in excellent yields by the newly developed I-promoted iodination-dearomatizative [4 + 2] cycloaddition cascade reaction. The subsequent structural diversification of the thus obtained was achieved by various coupling methods applied for the iodoalkene moiety. The high performance of as CDs was demonstrated in JC-1041XX/5CBs (1:1 wt ratio) as achiral host LCs, leading to the discovery of with a naphthofuran and long-chain alkyl unit that exhibited an extremely large molecular helical twisting power (molecular HTP or β) of -203 μm and produced cholesteric blue phases (BP I and BP II), namely, N*LC phases, comprising a higher-order supramolecular network.

Reported here is the synthesis of stretchable hydrogels with large spherulites of different morphologies by polymerization-induced crystallization of dopant molecules. By varying the concentrations of chemical crosslinker and initiator, or the light intensity for photopolymerization, the stiffness of polyacrylamide network is tunable to regulate the crystallization of dibenzo-24-crown-8-ether molecules that form spherulites in the hydrogels. Regular spherulites are formed in relatively stiff gels, whereas banded spherulites with twisted crystal fibers are obtained in soft gels.

Chiral macrocycles are attracting growing interest due to their broad applicability as ligands in asymmetric catalysis and as host molecules for chiral recognition. Robustness and high thermodynamic stability can be effectively achieved by strategically linking aromatic panels to construct an axially chiral macrocyclic framework. Cyclic concatenation of four quinoline units affords a fully sp-hybridized, non-planar macrocycle featuring four inwardly oriented, coordinatively active pyridyl nitrogen atoms.
