Carnosic acid, a phenolic diterpene, is enriched in the leaves of Lamiaceae plants, and is particularly high in dried leaves of Rosmarinus officinalis L. and Salvia officinalis. Carnosic acid has demonstrated inhibition of oxidative stress and inflammation, suppression of cell proliferation, and antibacterial activity. It is widely reported that Carnosic acid has a therapeutic potential in different types of cancer, mostly based on in vitro experiments. Carnosic acid has also shown neuroprotective effects in experimental models of neurodegenerative diseases, mainly through activation of the antioxidant NRF2/ARE pathway[1].

Carnosic acid (CA, 70 μM) inhibited Akt. PC-3 cells were treated without (Control) or with the indicated concentrations of CA or DTX for 24 or 48 h followed by whole cell lysate preparation and total protein yield assessment. Lysates (20 µg of protein) were resolved by SDS-PAGE and immunoblotted with specific antibodies against total or phosphorylated Akt (Ser473) or β-actin.

Western blots were used to analyze the expression of ferroptosis-related proteins and Mfn2 in A/R-induced cells after Carnosic acid (CA) or Fer-1 pretreatment. H9c2 cells in the CA + A/R group were treated with 10 μM CA for 48 h; H9c2 cells in the Fer-1 + A/R group were pretreated with 10 μM Fer-1 for 2 h. The protein level of PTGS2 was higher, and that of GPX4 was lower in the A/R group than in the control group. However, pretreatment with CA and Fer-1 prevented these changes.

Carnosic acid (CA) induced apoptosis of H1299 NSCLC cells. H1299 cells were treated for 24 h with 5 nM paclitaxel (PTX), 25 µM CA, or 50 µM CA, and nuclear morphology was assessed qualitatively using Hoechst 33342 and a BioTek Cytation 5 plate reader. CA-treated cells had noticeably smaller nuclei, which was consistent with the nuclear condensation that occurred during apoptosis.
