abstract = {The proto-oncogenic transcription factor c-MYC plays a
pivotal role in the development of tumorigenesis, cellular
proliferation, and the control of cell death. Its expression
is frequently altered in many cancer types, including
hematological malignancies such as leukemia. The dimer
isoniazide ELI-XXIII-98-2 is a derivative of the natural
product artemisinin, with two artemisinin molecules and an
isoniazide moiety as a linker in between them. In this
study, we aimed to study the anticancer activity and the
molecular mechanisms of this dimer molecule in
drug-sensitive CCRF-CEM leukemia cells and their
corresponding multidrug-resistant CEM/ADR5000 sub-line. The
growth inhibitory activity was studied using the resazurin
assay. To reveal the molecular mechanisms underlying the
growth inhibitory activity, we performed in silico molecular
docking, followed by several in vitro approaches such as the
MYC reporter assay, microscale thermophoresis, microarray
analyses, immunoblotting, qPCR, and comet assay. The
artemisinin dimer isoniazide showed a potent growth
inhibitory activity in CCRF-CEM but a 12-fold
cross-resistance in multidrug-resistant CEM/ADR5000 cells.
The molecular docking of artemisinin dimer isoniazide with
c-MYC revealed a good binding (lowest binding energy of
-9.84 ± 0.3 kcal/mol) and a predicted inhibition constant
(pKi) of 66.46 ± 29.5 nM, which was confirmed by microscale
thermophoresis and MYC reporter cell assays. Furthermore,
c-MYC expression was downregulated by this compound in
microarray hybridization and Western blotting analyses.
Finally, the artemisinin dimer isoniazide modulated the
expression of autophagy markers (LC3B and p62) and the DNA
damage marker pH2AX, indicating the stimulation of both
autophagy and DNA damage, respectively. Additionally, DNA
double-strand breaks were observed in the alkaline comet
assay. DNA damage, apoptosis, and autophagy induction could
be attributed to the inhibition of c-MYC by ELI-XXIII-98-2.},
