Synthesis of Polysubstituted Naphthalenes via Metal‐Free Borylative Cyclization of o‐Alkynylstyrenes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A selective, metal‐free method for the synthesis of boron‐functionalized polysubstituted naphthalenes via BCl3‐mediated cyclization of α‐substituted o‐alkynylstyrenes is described. The reaction exhibits broad substrate scope, tolerating various groups such as ethers, sulfides and halogens, and delivers high yields under mild conditions, even ...

Roles of Kdm6a and Kdm6b in Regulation of Mammalian Neural Regeneration

open access: yesAdvanced Science, Volume 12, Issue 16, April 24, 2025.
This study reveals that Kdm6a plays key roles in repressing either peripheral nervous system (PNS) or central nervous system (CNS) axon regeneration, whereas Kdm6b is not involved in regulating CNS axon regeneration. Moreover, both demethylases are able to regulate CNS neuronal survival after injury, but with non‐overlapping mechanisms.

Programmable NIR Responsive Nanocomposite Enables Noninvasive Intratympanic Delivery of Dexamethasone to Reverse Cisplatin Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
In this study, saponin‐coated silica@gold nanocarriers responsive to NIR radiation is developed to enhance intratympanic drug delivery for cisplatin‐induced hearing loss (CIHL) treatment. The biocompatibility and oto‐protective properties are validated both in vitro and in vivo.
