Giraldoid B and daphnolin have been studied for their various biological activities, particularly anti-inflammatory and antimicrobial properties. These compounds can inhibit the production of cytokines involved in inflammation, such as TNF-α and IL-6, showing potential as active agents for treating chronic inflammatory conditions like rheumatoid arthritis and gastritis.

In addition, both compounds exhibit antibacterial activity, especially against Gram-positive bacteria such as Staphylococcus aureus, which may lead to the development of alternative antimicrobial drugs in the future. Some research indicates antiviral effects at the cellular level, though these are still in preliminary stages.

Overall, giraldoid B and daphnolin are intriguing natural substances for research and drug development in areas such as immunity and infections. They are also noted for anti-inflammatory and cytotoxic properties, with potential in cancer studies due to their ability to inhibit tumor cell growth, and their complex structures make them candidates in natural product drug discovery.
