title: Chemical characterization of acylpolyamine toxins from venom of a trap-door spider and two tarantulas.
abstract: Two acylpolyamines are identified from venom of the trap-door spider, Hebestatis theveniti. These toxins (paralytic to lepidopteran insect larvae) are amides containing 3-(3-indolyl)lactic acid joined to spermine or 1,13-diamino-4,10-diazatridecane (Het389 and Het403, respectively). Het389 is also abundant in venom from a tarantual from Mozambique (Harpactirella sp.). Two additional acylpolyamines (Apc600 and Apc728) are partially characterized from venom of another tarantula, Aphonopelma chalcodes.
