Shinohara, Mai published the artcilePhoto-control of Cellular Uptake by the Selective Adsorption of Spiropyran Derivatives on Albumin, HPLC of Formula: 638-45-9, the publication is Chemistry Letters (2022), 51(6), 594-597, database is CAplus.
A photochromic spiropyran derivative (SP6) as a drug tag was prepared SP6 was selectively taken up into cells by photo-controlling the adsorption on albumin, which has attracted attention as a carrier for delivering drugs to tumor cells. The desorption of SP6 from albumin was achieved via the isomerization and hydrolysis of SP6.
