Disclosed are SH-labeling reagents containing acridine compounds represented by the following formula (I):
wherein
A represents the following group:
-(CH2)m1-
or
-(CH2)m2-Q-(CH2)n-
in which Q represents a group -S+RX--, a group -N+RR1X-- wherein R1 represents an alkyl group having 1 to 6 carbon atoms or an aryl group, a group
wherein R2 and R3 may be the same or different and are each independently a group -(CH2)k- (k: a number of 1 to 3) or -O(CH2CH2O)ℓ- (ℓ: a number of 1 to 3),
m1 stands for a number of 1 to 6,
m2 denotes a number of 0 to 2,
n means a number of 1 to 2;
R represents an alkyl group having 1 to 6 carbon atoms or an aryl group; and
X- represents an anion, or intermediates thereof; preparation processes of the acridine compounds; and methods for labeling analytes by using the compounds.

A mild and efficient method for the deprotection of aryl t-butyldimethysilyl (TBS) ethers is described. The protecting group TBS could be cleaved from aryl silyl ethers using cesium carbonate in DMF-H2O at room temperature to give the corresponding phenols in excellent yields. The reaction conditions allowed selective deprotection of aryl TBS-protected phenols in the presence of TBS, pbenyloxycarbonyl or tetrahydropyranyl-protected alcohols. (C) 2003 Elsevier Science Ltd.

GSH/ROS Dual-Responsive Supramolecular Nanoparticles Based on Pillar[6]arene and Betulinic Acid Prodrug for Chemo–Chemodynamic Combination Therapy
therapy were constructed via host–guest complexation between water-soluble pillar[6]arene and the ferrocene-modified natural anticancer product betulinic acid (BA) prodrug, followed by encapsulation of glucose oxidase (GOx) in the nanoparticles. The novel supramolecular nanoparticles could be activated by the overexpressed GSH and ROS in the tumor microenvironment (TME), not only accelerating the dissociation
