dellactinas

Dellactinas is a term that has appeared in a limited set of scientific publications as a provisional label for a proposed class of natural products. The exact definition of the term varies between sources, and it has not gained broad acceptance as a formal chemical family.

Described in some reports as small, lipophilic molecules, Dellactinas are said to feature a lactone-containing core with diverse substituents. Because no consensus structure exists, the term is often used descriptively rather than to denote a single, well-defined scaffold.

Reported occurrences come from a small number of isolation studies involving various microbes and plants in different environments. The claimed biosynthetic origins are not consistently supported, and there is no universally recognized biosynthetic gene cluster tied to the class.

Given the sparse and heterogeneous evidence, some researchers treat Dellactinas as a tentative category awaiting confirmation, while others caution against over-interpretation of early results. The term is sometimes encountered in patents or exploratory reports as a working label rather than a settled taxonomy.
