Trithio‐naphthalic anhydride‐based photosensitizer for photodynamic activity

open access: yesBulletin of the Korean Chemical Society, EarlyView.
A trithio‐naphthalic anhydride photosensitizer (NapS) is created by simple thionation, switching excited‐state pathways to deliver both type I and type II reactive oxygen species. NapS enables efficient photodynamic therapy under normoxia and hypoxia, achieving strong cancer cell killing with low dark toxicity.

Sequential, chromosome‐specific glutamine synthetase double knockout with Cas‐CLOVER establishes enhanced CHO platforms for cell line development

open access: yesBiotechnology Progress, EarlyView.
This study established the first creation of a commercially available double GS knockout (DKO) from a single KO in CHO‐K1 cells, called CleanCut GS CHO using Cas‐CLOVER. When combined with the Harbor‐IN transposase system, CleanCut GS CHO cells demonstrated a highly antibody productivity.
