Notes: 2'-O-(5-Chloroanthraniloyl)inosine-5'-O-triphosphate (2'-chloro ANT-ITP) and 3'-chloro ANT-ITP are fluorescent ITP derivatives, which undergo spontaneous isomerization.{69332} 2'(3')-chloro ANT-ITP selectively inhibits mammalian adenylyl cyclase 1 (AC1), AC2, and AC5 over B. pertussis AC toxin CyaA (Kis = 3.3, 8, 2, and 700 nM, respectively). A related derivative, 2'(3')-ANT-ATP (Item No. 38546), displays an emission maximum of 428 nm upon excitation at 330 nm.{67581}
