Chemical inhibitors of OBFC2B can exert their inhibitory effects through interference with DNA replication and repair processes, in which OBFC2B is a key player. Aphidicolin acts by targeting DNA polymerase, a critical enzyme for DNA replication. As OBFC2B is implicated in stabilizing replication forks, the inhibition of DNA polymerase can undermine the protein's functional role by impeding the replication process it is meant to safeguard. Similarly, Etoposide and Mitoxantrone, by stabilizing the DNA topoisomerase II complex in an aberrant state and intercalating into DNA respectively, prevent the ligation of DNA strands and promote DNA breaks. This accumulation of DNA damage indirectly restricts OBFC2B's function in DNA repair as the protein is overwhelmed by the increased demand for repair mechanisms. Camptothecin and Topotecan, both topoisomerase I inhibitors, lead to DNA damage during replication and transcription, further burdening the DNA repair machinery involving OBFC2B.
Actinomycin D, by binding to DNA, prevents RNA synthesis, thereby indirectly inhibiting the nucleoprotein complex formation essential for OBFC2B's role in DNA stability. Amsacrine, Daunorubicin, and Doxorubicin, all function as topoisomerase II inhibitors, which disrupt DNA synthesis and function, leading to an indirect inhibition of OBFC2B's DNA repair and replication activities. Bleomycin introduces DNA strand breaks by generating free radicals, adding to the pool of DNA damage that OBFC2B must process, thereby hindering its function. Hydroxyurea undermines OBFC2B's activity by depleting the pool of deoxyribonucleotides necessary for DNA synthesis, indirectly affecting the protein's involvement in DNA replication. Teniposide, like Etoposide, impedes topoisomerase II, exacerbating DNA damage and thus indirectly inhibiting the DNA repair and stabilization functions of OBFC2B, by causing an overload of DNA lesions that OBFC2B is unable to efficiently repair.
