8-Chloroadenosine is a nucleoside analog; metabolized in vivo to 8-Chloro-ATP. Incorporates into RNA during transcription and inhibits RNA synthesis. Exhibits cytotoxicity in MM.1S, RPMI-8226 and U266 cancer cell lines; induces G2/M cell cycle arrest and mitotic catastrophe in A549 and H1299 cells.
8-Chloroadenosine (cas# 34408-14-5) is a useful research chemical.8-Chloroadenosine is an analog of adenosine which depletes ATP and inhibits tumor growth in hematological malignancies as well as in lung and breast cancer cell lines.
8-Chloroadenosine (8-Cl-Ado), an adenosine analog, is a potential antitumor drug that is currently in phase-I clinical trials for chronic lymphocytic leukemia (CLL). It has been reported that 8-Cl-Ado inhibits cancer cell growth and induces apoptosis in Granta, JeKo, Mino, and SP-53 MCL cell lines by inhibition of both DNA and RNA syntheses. In addition, 8-Cl-Ado induces autophagy in primary CLL cells5 and in MCF-7 and BT-474 breast cancer cells6. Research has shown that 8-Cl-Ado inhibits the proliferation and migration of SK-BR-3, MDA-MB-231, and MCF-7 breast cancer cells by targeting the RNA-editing enzyme ADAR1[1].
