BACKGROUND: Acne is a prominent skin condition affecting >80% of teenagers and
young adults and ~650 million people globally. Isotretinoin, a vitamin A
derivative, is currently the standard of care for treatment. However, it has a
well-established teratogenic activity, a reason for the development of novel and
low-risk treatment options for acne. OBJECTIVE: To investigate the effectiveness
of Zolav(®), (a p-carboethoxy-tristyrylbenzene derivative) [corrected] a novel
antibiotic as a treatment for acne vulgaris. MATERIALS AND METHODS: Minimum
inhibitory concentration of Zolav(®) (a p-carboethoxy-tristyrylbenzene
derivative) against Propionibacterium acnes was determined by following a
standard protocol using Mueller-Hinton broth and serial dilutions in a 96-well
plate. Cytotoxicity effects on human umbilical vein endothelial cells and lung
cells in the presence of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative)
were investigated by determining the growth inhibition (GI50) concentration,
total growth inhibition concentration, and the lethal concentration of 50%
(LC50). The tryptophan auxotrophic mutant of Escherichia coli strain, WP2 uvrA
(ATCC 49979), was used for the AMES assay with the addition of Zolav(®) (a
p-carboethoxy-tristyrylbenzene derivative) tested for its ability to reverse the
mutation and induce bacterial growth. The in vivo effectiveness of Zolav(®) (a
p-carboethoxy-tristyrylbenzene derivative) was tested in a P. acnes mouse
intradermal model where the skin at the infection site was removed, homogenized,
and subjected to colony-forming unit (CFU) counts. RESULTS: Susceptibility
testing of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) against P.
acnes showed a minimum inhibitory concentration of 2 µg/mL against three strains
with no cytotoxicity and no mutagenicity observed at the highest concentrations
tested, 30 µM and 1,500 µg/plate, respectively. The use of Zolav(®) (a
p-carboethoxy-tristyrylbenzene derivative) at a concentration of 50 µg/mL (q8h)
elicited a two-log difference in CFU/g between the treatment group and the
control. CONCLUSION: This study demonstrates the potential of Zolav(®) (a
p-carboethoxy-tristyrylbenzene derivative) as a novel treatment for acne
vulgaris.
