2′-Chloro-2′-deoxycytidine (CAS 10212-19-8)

2′-Chloro-2′-deoxycytidine is a nucleoside analog used extensively in biochemical and molecular biology research, particularly in studies of DNA synthesis and repair mechanisms. Its mechanism of action involves incorporation into DNA during replication, where it can induce chain termination or cause mutations due to its altered structure. This analog is instrumental in understanding the fidelity and processivity of DNA polymerases, enzymes responsible for synthesizing new DNA strands. Researchers use 2′-chloro-2′-deoxycytidine to investigate the effects of nucleotide analogs on DNA replication and to study the mechanisms of nucleotide excision repair, a critical cellular process that removes damaged nucleotides from DNA. Additionally, it is utilized in research exploring the replication fidelity of various DNA polymerases, including those involved in viral replication, providing insights into antiviral strategies. The compound′s ability to induce specific types of DNA damage makes it a valuable tool in studying mutagenesis and the cellular response to DNA damage, including the activation of DNA damage checkpoints and repair pathways. Recent studies have focused on its application in understanding the mechanisms of drug resistance in cancer cells, where altered DNA repair capabilities can impact the effectiveness of nucleoside analogs. Overall, 2′-chloro-2′-deoxycytidine remains a crucial compound in the study of DNA synthesis, repair, and mutagenesis.
