Finding new cancer treatments from marine microbes

Discovery of PD-1/PDL-1 inhibitors from marine microbial natural products

NIH-funded research University of California, San Diego · NIH-10877154

This study is looking for new small drugs from ocean microbes that can help boost the immune system's ability to fight cancer by blocking a specific checkpoint called PD-1, and if successful, these drugs could offer a fresh option for cancer treatment.

What this research studies

This research focuses on discovering small molecule drugs that can inhibit the PD-1 checkpoint, a target in cancer immunotherapy. By utilizing a vast collection of marine microbial samples, the team will screen for compounds that can effectively bind to PD-1, which is crucial for activating the immune response against cancer cells. The project involves collaboration between the Scripps Institution of Oceanography and Nanjing University, where promising candidates will be tested in laboratory models. If successful, these small molecules could provide a new avenue for cancer treatment, potentially offering advantages over existing antibody therapies.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients with cancers that are currently treated with PD-1 inhibitors.

Not a fit: Patients who do not have cancer or those whose cancers are not responsive to PD-1 inhibitors may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new, more effective cancer treatments that enhance the immune system's ability to fight tumors.

How similar studies have performed: While the approach of using marine microbial metabolites is innovative, similar research has shown promise in discovering new anticancer agents from natural products.
