Pyrrolobenzodiazepines |
In Vitro
The unique structure of the pyrrolobenzodiazepine (PBD) dimers which contain two alkylating imine functionalities allows them to form interstrand or intrastrand DNA cross‐links in addition to mono‐alkylated adducts, thus resulting in greater DNA stabilization compared to monomeric PBDs. Due to the additional types of DNA adducts possible and the greater adduct stability, the C8‐linked PBD dimers generally have significantly greater cytotoxicity, antitumor activity and antibacterial activity compared to PBD monomers, and one such agent, SJG‐136, has reached Phase II clinical trials in ovarian cancer and leukaemia. Furthermore, related PBD dimers are now being used as payloads for antibody-drug conjugates (ADCs) due to their significant cytotoxicity[1].

PCNA Immunodetection Proliferation Assay
PCNA immunodetection measures proliferative activity by detecting proliferating cell nuclear antigen, a nuclear protein associated with DNA polymerase δ function and DNA replication. The assay readout is the proportion of PCNA-positive nuclei among total counted cells, but PCNA labeling is not identical to BrdU labeling because PCNA can mark late G1/early S-associated replication competence and may persist beyond active DNA synthesis depending on fixation and extraction conditions.
