A highly sensitive protocol for microscopy of alkyne lipids and fluorescently tagged or immunostained proteins[S]

open access: yesJournal of Lipid Research, 2016
The demand to study the cellular localization of specific lipids has led to recent advances in lipid probes and microscopy. Alkyne lipids bear a small, noninterfering tag and can be detected upon click reaction with an azide-coupled reporter. Fluorescent

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

open access: yesAdvanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

Design, Synthesis and Characterization of Novel Isoxazole Tagged Indole Hybrid Compounds

open access: yesOpen Chemistry, 2020
Sixteen new isoxazole tagged indole compounds have been synthesized via copper (I) catalyzed click chemistry of the aryl hydroxamoyl chloride and an indole containing alkyne moiety. The chemical structure of the synthesized compounds has been established

Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

open access: yesAdvanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Total Synthesis of Chiral Falcarindiol Analogues Using BINOL-Promoted Alkyne Addition to Aldehydes

open access: yesMolecules, 2016
An enantioselective total synthesis of chiral falcarindiol analogues from buta-1,3-diyn-1-yltriisopropylsilane is reported. The key step in this synthesis is BINOL-promoted asymmetric diacetylene addition to aldehydes.

Fluorohydration of alkynes via I(I)/I(III) catalysis

open access: yesBeilstein Journal of Organic Chemistry, 2020
Substrate specificity is ubiquitous in biological catalysis, but less pervasive in the realm of small-molecule catalysis. Herein, we disclose an intriguing example of substrate specificity that was observed whilst exploring catalysis-based routes to ...

Iridium Complex Catalyzed Carbonylative Alkyne−Alkyne Coupling for the Synthesis of Cyclopentadienones

open access: yes, 2016
Catalytic carbonylative alkyne−alkyne coupling proceeds using iridium−phosphine complexes under carbon monoxide at atmospheric pressure or a partial pressure of 0.2 atm.

A New Recruitable E3 Ligase UHRF1 Supporting Targeted Protein Degradation: A Minimal Azide as a Recruitment Ligand

open access: yesAdvanced Science, EarlyView.
Targeted protein degradation is often limited by the scarcity of usable E3 ligases. Herein, we report the first small‐molecule GPX4 degraders that incorporate either electrophilic warheads or a minimal azide group as an E3 recruitment ligand. The azide‐based degrader DK‐5070 effectively drives potent GPX4 degradation; mechanistic studies reveal that ...

Pinwheel-like Curved Aromatics from the Cyclotrimerization of Strained Alkyne Cycloparaphenylenes [PDF]

open access: yes
Curved aromatic hydrocarbons often display better solubility and more desirable electronic properties in comparison to their flat counterparts. Macrocyclic curved aromatics possess these traits as well as shape-persistent pores ideal for host-guest ...
