Toward Polymeric Room Temperature Acid Generators.

Although a variety of acid-generating molecules have been developed, the formation of toxic byproducts and the need for light-activation or temperatures that may be incompatible with physiological conditions leave room for the optimization of biocompatible acid-generators. Herein, we report 4-hydroxybenzyl chloride derivatives that generate hydrochloric acid via hydrolysis at the benzylic position at room temperature in the absence of light. Utilizing the acetal protected 4-hydroxybenzyl chloride scaffold, we access a myriad of compounds that generate acid at different rates.

Biometals as conformational modulators of α-synuclein photochemical crosslinking.

Metal dyshomeostasis has long been linked to Parkinson's disease (PD), and the amyloidogenic protein α-synuclein (αS) is universally recognized as a key player in PD pathology. Structural consequences upon coordination of copper and iron to αS have gained attention due to significant dyshomeostasis of both metals in the PD brain. Protein-metal association can navigate protein folding in distinctive pathways based on the identity of the bio-metal in question.
