|Section2= |Section3= }} Allopumiliotoxin 267A is a toxin found in the skin of several poison frogs of the family ''Dendrobates''.〔Edwards MW, Daly JW, Myers CW. Alkaloids from a panamanian poison frog, Dendrobates speciosus: identification of pumiliotoxin-A and allopumiliotoxin class alkaloids, 3,5-disubstituted indolizidines, 5-substituted 8-methylindolizidines, and a 2-methyl-6-nonyl-4-hydroxypiperidine. ''Journal of Natural Products''. 1988 Nov-Dec;51(6):1188-97. PMID 3236011〕 It is a member of the class of compounds known as allopumiliotoxins. The frogs produce the toxin by modifying the original version, pumiliotoxin 251D.〔Daly JW, Garraffo HM, Spande TF, Clark VC, Ma J, Ziffer H, Cover JF Jr. Evidence for an enantioselective pumiliotoxin 7-hydroxylase in dendrobatid poison frogs of the genus Dendrobates. ''Proceedings of the National Academy of Sciences USA''. 2003 Sep 16;100(19):11092-7. PMID 12960405〕 It has been tested on mice and found to be five times more potent than the former version. It has been produced synthetically through a variety of different routes.〔Comins DL, Huang S, McArdle CL, Ingalls CL.
