Salt-Adapted Microorganisms: A Promising Resource for Novel Anti-Cancer Drug Discovery.

Area of Science:

• Microbiology
• Pharmacology
• Oncology

Background:

• Microorganisms are a key source of natural anticancer agents used in clinical oncology.
• Salt-adapted microbes (halophilic and halotolerant) from high-salinity environments are gaining attention for drug discovery.
• These microbes possess unique adaptations and diverse secondary metabolites with therapeutic potential.

Purpose of the Study:

• To review two decades of research on salt-adapted microorganisms and cancer.
• To evaluate the therapeutic potential of these microbes against major cancer cell lines.
• To assess their role in addressing chemotherapy resistance and toxicity.

Main Methods:

• Literature review consolidating research on salt-adapted microbes and anticancer activity.
• Analysis of global cancer statistics to identify key targets.
• Evaluation of secondary metabolites from halophilic and halotolerant species.

Main Results:

• Salt-adapted microbes show significant promise as sources of anticancer agents.
• Their bioactive metabolites exhibit potent inhibitory effects on major cancer cell lines, especially lung and breast cancer.
• Structurally unique metabolites display enhanced cytotoxicity compared to conventional drugs.

Conclusions:

• Salt-adapted microorganisms are an underexplored, high-value resource for novel anticancer drug discovery.
• Their unique metabolites offer potential solutions for overcoming chemotherapy resistance.
• These microbes may help mitigate treatment-related toxicity in cancer patients.
