Gu, Xiaoke published the artcileDiscovery of thiosemicarbazone-containing compounds with potent anti-proliferation activity against drug-resistant K562/A02 cells, COA of Formula: C12H9NO, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(24), 127638, database is CAplus and MEDLINE.
P-glycoprotein (P-gp)-mediated multidrug resistance (MDR) is a major obstacle to successful chemotherapy for leukemia. A series of thiosemicarbazone-containing compounds were synthesized. Biol. evaluation showed that the most active compound (E)-6-(2-(1-(4-bromophenyl)ethylidene)hydrazine-1-carbothioamido)-N-hydroxyhexanamide displayed potent anti-leukemia activity against P-gp overexpressing drug-resistant K562/A02 cells, with an IC50 value of 0.44μM. Notably, compound (E)-6-(2-(1-(4-bromophenyl)ethylidene)hydrazine-1-carbothioamido)-N-hydroxyhexanamide exhibited a selective killing effect on K562/A02 cells by dose-dependently increasing the intracellular levels of reactive oxygen species (ROS), thus exerting a potential collateral sensitivity (CS)-promoting effect in vitro. Moreover, compound (E)-6-(2-(1-(4-bromophenyl)ethylidene)hydrazine-1-carbothioamido)-N-hydroxyhexanamide could inhibit HDAC1 and HDAC6, and induce the apoptosis of K562/A02 cells by increasing the expression of Bax, decreasing Bcl-2 protein level, and promoting the cleavage of caspase-3 and PARP, resp. Overall, (E)-6-(2-(1-(4-bromophenyl)ethylidene)hydrazine-1-carbothioamido)-N-hydroxyhexanamide may be a potential anti-cancer agent against drug-resistant myelogenous leukemia.
