Cytotoxic Potential of Petroleum ether, Ethyl Acetate, Chloroform, and Ethanol Extracts of Lavandula Coronopifolia Against Human Breast Carcinoma Cell line (MDA-MB-321)

Cytotoxic effects of Lavandula angustifolia seed extracts on the viability of Huh-7 and Chang liver cells

Flowering plants are valuable in numerous ways, including food/feed supply for living organisms, fuel production, and medicinal uses. Several plant extracts/products are used to treat variety of serious ailments in human and animals. Lavandula angustifolia is a flowering plant that possesses anti-inflammatory and anti-depressive medicinal properties. Cancer is a deadly disorder affecting millions of people globally. It affects several human organs, including liver, stomach, and lungs. Several researchers are doing efforts to eliminate the disease around the globe. In this study, Chang and Huh-7 liver cell lines were utilized as human normal hepatocyte model and innovation to mimic the liver environment. Cytotoxicity of L. angustifolia seed extracts was investigated at two different concentrations (50% and 100%) against Chang and Huh-7 liver cell lines by colorimetric assay which is used to assess cell metabolic activities. The Chang and Huh-7 liver cell lines were treated with L. angustifolia seeds extracts (50% and 100%) and incubated for 24 and 48 hours under standard conditions (37°C, 5% CO₂). The 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay was employed to quantify cell survival. Seed extracts of L. angustifolia exerted varied cytotoxic effects depending on the concentration and treatment duration. The results indicated that L. angustifolia seed extracts with 100% concentration exhibited the highest cytotoxicity against Huh-7 and Chang liver cell lines. In conclusion, L. angustifolia seed extracts exhibited cytotoxic activity which can be enhanced based on the concentration and treatment duration. The findings of the current study are critical for the development of novel herbal-based therapies for fatal disorders such as liver cancer. However, more investigations are required to reveal cytotoxicity mechanisms of L. angustifolia seed extracts.

Review On Documented Medicinal Plants Used For The Treatment Of Cancer

Background:

Cancer is a frightful disease and it is the second leading cause of death worldwide. Naturally derived compounds are gaining interest of research workers as they have less toxic side effects as compared to currently used treatments such as chemotherapy. Plants are the pool of chemical compounds which provides a promising future for research on cancer.

Objective:

This review paper provides updated information gathered on medicinal plants and isolated phytoconstituents used as anticancer agents and summarises the plant extracts and their isolated chemical constituents exhibiting anticancer potential on clinical trials.

Methods:

An extensive bibliographic investigation was carried out by analysing worldwide established scientific databases like SCOPUS, PUBMED, SCIELO, ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar etc. In next few decades, herbal medicine may become a new epoch of medical system.

Results:

Many researches are going on medicinal plants for the treatment of cancer but it is a time to increase further experimental studies on plant extracts and their chemical constituents to find out their mechanism of action at molecular level.

Conclusion:

The article may help many researchers to start off further experimentation that might lead to the drugs for the cancer treatment.

An In Vitro Evaluation of the Molecular Mechanisms of Action of Medical Plants from the Lamiaceae Family as Effective Sources of Active Compounds against Human Cancer Cell Lines

It is predicted that 1.8 million new cancer cases will be diagnosed worldwide in 2020; of these, the incidence of lung, colon, breast, and prostate cancers will be 22%, 9%, 7%, and 5%, respectively according to the National Cancer Institute. As the global medical cost of cancer in 2020 will exceed about $150 billion, new approaches and novel alternative chemoprevention molecules are needed. Research indicates that the plants of the Lamiaceae family may offer such potential. The present study reviews selected species from the Lamiaceae and their active compounds that may have the potential to inhibit the growth of lung, breast, prostate, and colon cancer cells; it examines the effects of whole extracts, individual compounds, and essential oils, and it discusses their underlying molecular mechanisms of action. The studied members of the Lamiaceae are sources of crucial phytochemicals that may be important modulators of cancer-related molecular targets and can be used as effective factors to support anti-tumor treatment.
