Methanol, or methyl alcohol, is a colorless solvent found in a variety of automotive products including windshield washer fluid, gasoline antifreeze and alternative fuels. It is also used as an industrial solvent for household products such as paint removers and rubbing alcohol. <\/p>\n
While the toxicity of methanol to humans is well known, the compound is found naturally in the human body in small amounts. Certain fruits and vegetables contain it, and methanol may be produced as an unintended byproduct of the fermentation process. <\/p>\n
Now, researchers at universities in Cameroon and Turkey are using the compound in an unusual way as a treatment against malignant mesothelioma cell lines. <\/p>\n
Dr. Victor Kuete, a biochemist at the University of Dschang in Cameroon, led the research team that tested methanol extracts found in African plants on mesothelioma and four other cancers. <\/p>\n
The results, published recently in the journal BMC Complementary and Alternative Medicine, are promising. <\/p>\n
These data highlight the usefulness of these extracts in the fight against solid cancers, Kuete wrote in the study. This hypothesis is strengthened by the good selectivity index of the tested extract, which is compatible with their possible use in cancer chemotherapy. <\/p>\n
Kuete has spent many years investigating the cytotoxicity, or toxicity to living cells, of compounds and extracts found in African plants. <\/p>\n
In December 2016, Kuete discovered that an organic compound called rapanone caused cell death (apoptosis) in mesothelioma cell lines. <\/p>\n
We found that rapanone likely induced apoptosis via loss of mitochondrial membrane potential, Kuete told Asbestos.com. <\/p>\n
The latest naturally derived compound with success fighting mesothelioma cells comes from the leaves of Kalanchoe crenata, a perennial succulent shrub native to tropical regions of Africa. <\/p>\n
Methanol extracts from Kalanchoe crenata leaves (KCL) were tested against five cancers: Mesothelioma, colon cancer, non-small cell lung cancer, hepatocellular carcinoma (liver cancer) and breast cancer. <\/p>\n
KCL was most potent against mesothelioma cell lines, while it didnt have a significant effect against the other cancers tested. <\/p>\n
Kuete noted that this is the first report on the anti-cancer activity of KCL. The plant is traditionally used in alternative medicine as a diabetic and anti-inflammatory drug. <\/p>\n
Other medicinal plants tested in the study included: <\/p>\n
Overall, the Elephantopus mollis extract was most effective against the five cancer cell lines. <\/p>\n
Elephantopus mollis and Millettia macrophylla are traditionally used in the treatment of cancers, Kuete wrote. The two plants, [especially]mollis, had cytotoxic effects on the tested carcinoma cells, validating their traditional use in the management of malignancies. <\/p>\n
Small-cell lung cancer was the least responsive to elephants foot and the least responsive cancer overall. Only KCL showed significant cell death against the lung cancer cell lines. The only cancer with better results from KCL was mesothelioma. <\/p>\n
Despite the promising results, using organic compounds to treat mesothelioma is a novel therapy at this point, but Kuete hopes his continued work in the area will spark future investigations into using KCL and other plants as a basis for cytotoxic drugs. <\/p>\n
For his latest study, Kuete and his team used untreated cells as a control and doxorubicin a popular chemotherapeutic agent used to treat a number of cancers, including mesothelioma as a drug control. <\/p>\n
Of the five cancers in the study, doxorubicin was most effective against mesothelioma, followed by hepatocellular carcinoma. <\/p>\n
All of the doxorubicin results were significantly better than any of the plant extracts, but the findings could give clinical researchers another option to possibly enhance the effectiveness of future cancer drugs. <\/p>\n
This study provides evidences of the cytotoxicity of the tested plant extract and highlights the good activity of Elephantopus mollis and Kalanchoe crenata, Kuete wrote. They deserve more exploration to develop novel cytotoxic drugs. <\/p>\n
