Bufotalin is a steroid lactone. It is functionally related to a bufanolide. Bufotalin is a natural product found in Bufo gargarizans, Duttaphrynus melanostictus Bufotalin is a cardiotoxic bufanolide steroid, cardiac glycoside analogue, secreted by a number of toad species.[2][3] Bufotalin can be extracted from the skin parotoid glands of several types of toad. Rhinella marina (Cane toad), Rhaebo guttatus (Smooth-sided toad), Bufo melanostictus (Asian toad), and Bufo bufo (common European toad) are sources of bufotalin. Traditional medicine Bufotalin is part of Ch'an Su, a traditional Chinese medicine used for cancer. It is also known as Venenum Bufonis or senso (Japanese).[5] Toxicity Specifically, in cats the lethal median dose is 0.13 mg/kg.[1] and in dogs is 0.36 mg/kg (intravenous).[6] Knowing this it is advisable to monitor those functions continuously using an EKG. As there is no antidote against bufotalin all occurring symptoms need to be treated separately or if possible in combination with others. To increase the clearance theoretically, due to the similarities with digitoxin, cholestyramine, a bile salt, might help.[6] Recent animal studies have shown that taurine restores cardiac functions.[7] Symptomatic measures include lignocaine, atropine and phenytoin for cardiac toxicity and intravenous potassium compounds to correct hyperkalaemia from its effect on the Na+/K+ ATPase pump.[6] Pharmacology and mechanism of action After a single intravenous injection, bufotalin gets quickly distributed and eliminated from the blood plasma with a half-time of 28.6 minutes and a MRT of 14.7 min. After 30 minutes after an administration of bufotalin, the concentrations within the brain and lungs are significantly higher than those in blood and other tissues.[8] It also increases cancer cell's susceptibility to apoptosis via TNF-α signalling by the BH3 interacting domain death agonist and STAT proteins.[9] Bufotalin induces apoptosis in vitro in human hepatocellular carcinoma Hep 3B cells and might involve caspases and apoptosis inducing factor (AIF).[10] The use of bufotalin as a cancer treating compound is still in the experimental phase. It also arrests cell cycle at G(2)/M, by up- and down- regulation of several enzymes. Bufotalin. CAS Common Chemistry.

desmethylastemizole is a metabolite of astemizole. Astemizole (R43512, marketed under the brand name Hismanal) was a second generation antihistamine drug which has a long duration of action. Astemizole was discovered by Janssen Pharmaceutica in 1977. It has been withdrawn from the market in most countries because of rare but potentially fatal side effects. (Wikipedia)
