FooDB Name | ajmaline |

Description | Ajmaline, also known as (+)-ajmaline, is a member of the class of compounds known as ajmaline-sarpagine alkaloids. Ajmaline-sarpagine alkaloids are organic compounds containing either of the ajmalan, sarpagan skeleton, or derivative thereof. The Sarpagine (Akuammidine) group, based on the sarpagan nucleus, arises from bond formation between C-16 and C-5 of the corynantheine precursor. Ajmaline alkaloids are based on a 17,19-secoyohimban skeleton (oxayohimban) which is invariably present as an ether. Ajmaline is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Ajmaline can be synthesized from ajmalan. Ajmaline is also a parent compound for other transformation products, including but not limited to, vinorine, norajmaline, and 17-O-acetylajmaline. Ajmaline can be found in a number of food items such as soursop, jew's ear, small-leaf linden, and soft-necked garlic, which makes ajmaline a potential biomarker for the consumption of these food products. Ajmaline can be found primarily in blood and urine. Ajmaline is a drug which is used for use as an antiarrhythmic agent. The compound was first isolated by Salimuzzaman Siddiqui in 1931 from the roots of Rauvolfia serpentina. He named it ajmaline, after Hakim Ajmal Khan, one of the most illustrious practitioners of Unani medicine in South Asia. Ajmaline can be found in most species of the Rauvolfia genus as well as Catharanthus roseus. In addition to Southeast Asia, Rauvolfia species have also been found in tropical regions of India, Africa, South America, and some oceanic islands. Other indole alkaloids found in Rauvolfia include reserpine, ajmalicine, serpentine, corynanthine, and yohimbine. While 86 alkaloids have been discovered throughout Rauvolfia vomitoria, ajmaline is mainly isolated from the stem bark and roots of the plant . The class I antiarrhythmic agents interfere with the sodium channel. A class IA agent lengthens the action potential (right shift) which brings about improvement in abnormal heart rhythms. This drug in particular has a high affinity for the Nav 1.5 sodium channel (DrugBank). |
