Praziquantel
C19H24N2O2 (312.18376839999996)
Praziquantel is only found in individuals that have used or taken this drug. It is an anthelmintic used in most schistosome and many cestode infestations. [PubChem]Praziquantel works by causing severe spasms and paralysis of the worms muscles. This paralysis is accompanied - and probably caused - by a rapid Ca 2+ influx inside the schistosome. Morphological alterations are another early effect of praziquantel. These morphological alterations are accompanied by an increased exposure of schistosome antigens at the parasite surface. The worms are then either completely destroyed in the intestine or passed in the stool. An interesting quirk of praziquantel is that it is relatively ineffective against juvenile schistosomes. While initially effective, effectiveness against schistosomes decreases until it reaches a minimum at 3-4 weeks. Effectiveness then increases again until it is once again fully effective at 6-7 weeks. Glutathione S-transferase (GST), an essential detoxification enzyme in parasitic helminths, is a major vaccine target and a drug target against schistosomiasis. Schistosome calcium ion channels are currently the only known target of praziquantel.

norajmaline
C19H24N2O2 (312.18376839999996)
Norajmaline 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. Norajmaline is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Norajmaline can be found in a number of food items such as roselle, chayote, savoy cabbage, and onion-family vegetables, which makes norajmaline a potential biomarker for the consumption of these food products.
