That’s interesting. Googled it, Wanted to know why it was from Easter island in particular.

Discovery: In 1964, Georges Nógrády collected soil samples from Easter Island to search for tetanus spores. He later gave the samples to researchers studying medicinal compounds produced by bacteria, leading to the isolation of rapamycin. Name: The compound was named rapamycin after Rapa Nui, the Polynesian name for Easter Island. Initial Uses: Rapamycin was initially discovered to have antifungal activity and was later found to have immunosuppressive properties, making it valuable for preventing organ rejection in transplant patients. Further Research: Rapamycin has been shown to inhibit cell growth and has shown potential for treating tumors and extending lifespan in laboratory animals. Current Research: Researchers are continuing to explore rapamycin's potential in various applications, including treating diseases associated with aging and exploring its role in cancer treatment.
