Nivealin
Nivealin is a naturally occurring alkaloid found in certain plant species, notably those belonging to the *Annona* genus, such as *Annona muricata* (soursop). Chemically, it is classified as a tetrahydroisoquinoline alkaloid. Nivealin has been a subject of scientific interest due to its potential biological activities. Research has explored its pharmacological properties, with some studies investigating its cytotoxic effects against various cancer cell lines. These investigations often focus on its potential as an antineoplastic agent, though much of this work remains in the preclinical stages. Beyond its cytotoxic potential, nivealin has also been examined for other biological activities, including anti-inflammatory and antioxidant properties. The extraction and purification of nivealin from plant sources are typically achieved through standard phytochemical methods. While nivealin shows promise in preliminary research, further studies are required to fully understand its efficacy, safety, and mechanisms of action before any therapeutic applications can be considered. Its presence in traditional medicine practices involving plants like soursop has also contributed to scientific curiosity surrounding its compounds.
