Therefore, Zinc finger protein 726 (ZNF726) can be considered an attractive therapeutic target for the treatment of breast cancer. Based on these views, this study aimed to identify potent inhibitors targeting ZNF726 activity utilizing a structure-based molecular docking method. Virtual screening with the LOPAC library led to the identification of zoledronic acid monohydrate as a top-hit compound featuring good docking and MMGBSA scores. Further, zoledronic acid monohydrate was found to inhibit the proliferation potential of breast cancer cells. Ectopic expression of ZNF726 led to an increase in the cholesterol levels of breast cancer cells. Further, this study confirms that zoledronic acid tends to decrease the cholesterol content in ZNF726-overexpressed cells along with an inhibitory effect on breast cancer cell proliferation. Conclusively, these findings suggested that the cholesterol pathway and oncogenic ZNF726 form an interdependent relationship, and therefore, targeting the cholesterol pathway may prove to be a promising strategy to inhibit oncogenic ZNF726 expression in breast cancer. Additionally, this study also reveals nine phytochemicals that might target ZNF726 activity, identified through virtual screening by the IMPPAT library. Three phytochemicals (Swertiamacroside, Terflavin A, and N-(3-Carboxy-2,3-dihydroxypropyl)-4-((carboxymethyl)amino) threonine) out of the nine phytochemicals are still unknown for their anticancer role which needs further exploration.

In addition, both analogues were more effective in inhibiting the proliferation of the MCF-7 cancer cell line. All tested compounds exhibited binding affinity towards caspase-3 and the receptors EGFR, HER2 and VEGFR.

Our study found that NF-1 effectively attenuated placental dysfunction by reducing glucocorticoid (GC) production and boosting 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) expression, a key enzyme for GC inactivation. Furthermore, NF-1 reduced OS markers such as malondialdehyde (MDA) and reactive oxygen species (ROS) in both placental tissue and HTR8/SVneo cells. The protective effects of NF-1 were correlated with the suppression of the general control nonderepressible 2 (GCN2)/eukaryotic initiation factor 2α (eIF2α) signaling pathway, which became activated under OS conditions.
