Senecio herb is used /as a folk remedy/ for diabetes mellitus, hemorrhage, high blood pressure, for spasms, and as a uterine stimulant.
Blumenthal M, ed; The Complete German Commission E Monographs: Therapeutic Guide to Herbal Medicines p. 376 (1998)
Senecio herb contains varying amounts of toxic pyrrolizidine alkaloids (PA) which are known to have organotoxic, in particular hepatotoxic,effects
Blumenthal M, ed; The Complete German Commission E Monographs: Therapeutic Guide to Herbal Medicines p. 376 (1998)
The therapeutic administration of senecio herb is not justifiable because of its insufficient or undocumented effectiveness and the presence of toxic pyrrolizidine alkaloids.

Antineoplastic Agents, Phytogenic
Agents obtained from higher plants that have demonstrable cytostatic or antineoplastic activity. (See all compounds classified as Antineoplastic Agents, Phytogenic.)
In animal studies highest concentrations were found in the liver, lungs, kidneys and spleen. /pyrrolizidine alkaloids/

Blood levels of senecionine in rats given 0.1 LD50 ip were determined. The levels were 0.38, 0.32, and 0.14 mg/litre at 0.5, 1, and 2 h after injection, respectively.

...Senecionine... /was/ studied regarding the distribution, excretion, transfer into milk, and covalent binding to hepatic macromolecules in BALB/c mice. After injection, radioactivity was rapidly excreted in the urine and feces (84% or greater) within 16 hr. The liver contained over 1.5% of the dose at 16 hr. A small amount, 0.04%, of the dose was transferred into the milk in 16 hr; the majority of radioactivity was found in the skim-milk fraction, suggesting that the PA's were transferred to the milk as water-soluble metabolites. ...The binding to calf thymus DNA and microsomal macromolecules was measured in vitro. The binding was diminished in the absence of O2 or a NADPH-generating system or by boiling the microsomes.

...Following intravenous administration of [14C]SEN (60 mg/kg, 10 microCi/kg), bile, urine and blood were collected over a 7-hr period. Of the total administered radioactivity, 44% and 43% were excreted in the bile and urine, respectively. Using mass spectroscopy, senecionine N-oxide (SENNOX) was identified as the major metabolite in bile (52% of 44%) and urine (30% of 43%). For the total 7 hr, <5% in bile and 18% in urine was excreted as parent alkaloid.

Using microsomes from livers of phenobarbitone-pretreated male rats, pyrrolizidine alkaloids tested were metabolized to n-oxides and pyrroles.

The in vitro mouse hepatic microsomal metabolism of the macrocyclic pyrrolizidine alkaloid senecionine was studied. Senecic acid, senecionine n-oxide and 19-hydroxysenecionine, a new metabolite, were isolated from the microsomal enzyme system of balb/c mice.

The toxic pyrrolizidine alkaloids, such as senecionine, are cyclic arylamines that are dehydrogenated by cytochrome P450 (CYP3A4) to the corresponding pyrroles. Pyrroles themselves are nucleophiles, but electrophiles are generated through the loss of substituents on the pyrrolizidine nucleus... .

In animals, the major metabolic routes of pyrrolizidine alkaloids are: (a) hydrolysis of the ester groups; (b) N-oxidation; and (c) dehydrogenation of the pyrrolizidine nucleus to pyrrolic derivatives. Routes (a) and (b) are believed to be detoxification mechanisms. Route (c) leads to toxic metabolites. Route (a) occurs in liver and blood; routes (b) and (c) are brought about in the liver by the microsomal mixed function oxidase system. /pyrrolizidine alkaloids/

Within a few hours, only a relatively small proportion of the administered dose remains in the body. Much of this is in the form of metabolites bound to tissue contents. A pyrrolizidine N-oxide disappeared from the serum after IV administration in animals, with initial half-lives of 3 to 20 minutes. /pyrrolizidine alkaloids/

On the isolated guinea pig ileum preparation, platyphylline, supinine, heleurine, and cynaustraline were more potent in antagonizing responses to acetylcholine (ii). Their anticholinergic activity appeared to involve a competitive mechanism. The pyrrolizidine alkaloids had no appreciable activity as antagonists of (ii) in the isolated toad rectus abdominis preparation.

The activation of the alkaloids by mixed-function oxidases leads to pyrrolic dehydro-alkaloids which are reactive alkylating agents. The liver necrosis results from binding of the metabolites with the liver cell. Some metabolites are released into the circulation and are believed to pass beyond the liver to the lung causing vascular lesions. The pyrrolic metabolites are cytotoxic and act on the hepatocytes and on the endothelium of blood vessels of the liver and lung. /pyrrolizidine alkaloids/
