Mito-LND (Mito-Lonidamine) is an orally active and mitochondria-targeted inhibitor of oxidative phosphorylation (OXPHOS). Mito-LND inhibits mitochondrial bioenergetics, stimulates the formation of reactive oxygen species, and induces autophagic cell death in lung cancer cells[1].
Mito-LND blocks lung cancer growth, migration, and invasion. Mito-LND inhibits cell growth of H2030BrM3 and A549 cells with IC50 values of 0.74 µM and 0.69 µM, respectively[1].Mito-LND inhibits mitochondrial complex I and II activities with IC50 values of 1.2 µM and 2.4 µM, respectively in H2030BrM3 cells[1]. Mito-LND (1 µM) increases ROS generation in H2030BrM3 lung cancer cells. Mito-LND potently induces mitochondrial ROS generation in H2030BrM3 lung cancer cells[1].Mito-LND (2 µM) decreases the levels of phosphorylated AKT. Mito-LND also decreases the phosphorylation of P70S6K and other energy-sensing proteins in both the parental and metastatic lung cancer cell lines, indicating that Mito-LND specifically downregulates mTOR signaling[1].
Mito-LND (7.5 µmol/kg; oral gavage; 5 days per week; for 3 consecutive weeks) treatment markedly enhanced potency against both lung cancer progression and metastasis[1]. Mito-LND also decreases the rate of growth of A549 tumor xenografts[1].Mito-LND treatment shows a marked decrease in lung cancer brain metastasis in NOD/SCID mice bearing H2030BrM3 cells[1].

Chemoprevention of Lung Cancer with a Combination of Mitochondria-Targeted Compounds
Cancers (Basel) 2022 May 21;14(10):2538.PMID:35626143DOI:10.3390/cancers14102538.
Combined treatment targeting mitochondria may improve the efficacy of lung cancer chemoprevention. Here, mitochondria-targeted honokiol (Mito-HNK), an inhibitor of mitochondrial complex I and STAT3 phosphorylation, and mitochondria-targeted lonidamine (Mito-LND), an inhibitor of mitochondrial complexes I/II and AKT/mTOR/p70S6K signaling, were evaluated for their combinational chemopreventive efficacy on mouse lung carcinogenesis. All chemopreventive treatments began one-week post-carcinogen treatment and continued daily for 24 weeks. No evidence of toxicity (including liver toxicity) was detected by monitoring serum levels of alanine aminotransferase and aspartate aminotransferase enzymes. Mito-HNK or Mito-LND treatment alone reduced tumor load by 56% and 48%, respectively, whereas the combination of Mito-HNK and Mito-LND reduced tumor load by 83%. To understand the potential mechanism(s) of action for the observed combinatorial effects, single-cell RNA sequencing was performed using mouse tumors treated with Mito-HNK, Mito-LND, and their combination. In lung tumor cells, Mito-HNK treatment blocked the expression of genes involved in mitochondrial complex ǀ, oxidative phosphorylation, glycolysis, and STAT3 signaling. Mito-LND inhibited the expression of genes for mitochondrial complexes I/II, oxidative phosphorylation, and AKT/mTOR/p70S6K signaling in lung tumor cells. In addition to these changes, a combination of Mito-HNK with Mito-LND decreased arginine and proline metabolism, N-glycan biosynthesis, and tryptophan metabolism in lung tumor cells. Our results demonstrate that Mito-LND enhanced the antitumor efficacy of Mito-HNK, where both compounds inhibited common targets (oxidative phosphorylation) as well as unique targets for each agent (STAT3 and mTOR signaling). Therefore, the combination of Mito-HNK with Mito-LND may present an effective strategy for lung cancer chemoprevention.
Targeting lonidamine to mitochondria mitigates lung tumorigenesis and brain metastasis
Nat Commun 2019 May 17;10(1):2205.PMID:31101821DOI:10.1038/s41467-019-10042-1.
Lung cancer often has a poor prognosis, with brain metastases a major reason for mortality. We modified lonidamine (LND), an antiglycolytic drug with limited efficacy, to mitochondria-targeted mito-lonidamine (Mito-LND) which is 100-fold more potent. Mito-LND, a tumor-selective inhibitor of oxidative phosphorylation, inhibits mitochondrial bioenergetics in lung cancer cells and mitigates lung cancer cell viability, growth, progression, and metastasis of lung cancer xenografts in mice. Mito-LND blocks lung tumor development and brain metastasis by inhibiting mitochondrial bioenergetics, stimulating the formation of reactive oxygen species, oxidizing mitochondrial peroxiredoxin, inactivating AKT/mTOR/p70S6K signaling, and inducing autophagic cell death in lung cancer cells. Mito-LND causes no toxicity in mice even when administered for eight weeks at 50 times the effective cancer inhibitory dose. Collectively, these findings show that mitochondrial targeting of LND is a promising therapeutic approach for investigating the role of autophagy in mitigating lung cancer development and brain metastasis.
Multifaceted Elevation of ROS Generation for Effective Cancer Suppression
Nanomaterials (Basel) 2022 Sep 11;12(18):3150.PMID:36144938DOI:10.3390/nano12183150.
The in situ lactate oxidase (LOx) catalysis is highly efficient in reducing oxygen to H2O2 due to the abundant lactate substrate in the hypoxia tumor microenvironment. Dynamic therapy, including chemodynamic therapy (CDT), photodynamic therapy (PDT), and enzyme dynamic therapy (EDT), could generate reactive oxygen species (ROS) including ·OH and 1O2 through the disproportionate or cascade biocatalytic reaction of H2O2 in the tumor region. Here, we demonstrate a ROS-based tumor therapy by integrating LOx and the antiglycolytic drug Mito-LND into Fe3O4/g-C3N4 nanoparticles coated with CaCO3 (denoted as FGLMC). The LOx can catalyze endogenous lactate to produce H2O2, which decomposes cascades into ·OH and 1O2 through Fenton reaction-induced CDT and photo-triggered PDT. Meanwhile, the released Mito-LND contributes to metabolic therapy by cutting off the source of lactate and increasing ROS generation in mitochondria for further improvement in CDT and PDT. The results showed that the FGLMC nanoplatform can multifacetedly elevate ROS generation and cause fatal damage to cancer cells, leading to effective cancer suppression. This multidirectional ROS regulation strategy has therapeutic potential for different types of tumors.
