| Common Name | (+)-maackiain |
|---|
| Description | (+)-Maackiain, also known as inermin, belongs to the class of organic compounds known as pterocarpans. These are benzo-pyrano-furano-benzene compounds, containing the 6H-[1]benzofuro[3,2-c]chromene skeleton. They are derivatives of isoflavonoids (+)-maackiain is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. (+)-maackiain is found in Aldina heterophylla, Artemisia indica, Maackia amurensis, Machaerium aristulatum, Millettia leucantha, Ononis vaginalis, Sophora flavescens, Styphnolobium japonicum and Thermopsis fabacea. (+)-maackiain was first documented in 2022 (PMID: 35583301). Based on a literature review a small amount of articles have been published on (+)-maackiain (PMID: 35782063) (PMID: 36010884) (PMID: 35405595) (PMID: 35367764). |
