  Alantrypinone and its derivatives: Synthesis and antagonist activity toward insect GABA receptors

  摘要：

  The gamma-aminobutyric acid (GABA) receptor bears important sites of action for insecticides. Alantrypinone is an insecticidal alkaloid that acts as a selective antagonist for housefly (vs rat) GABA receptors, and is considered to be a lead compound for the development of a safer insecticide. In an attempt to obtain compounds with greater activity, a series of racemic alantrypinone derivatives were systematically synthesized using hetero Diels-Alder reactions, and a total of34 compounds were examined for their ability to inhibit the specific binding of [H-3]4'-ethynyl-4-n-propylbicycloorthobenzoate, a high-affinity non-competitive antagonist, to housefly-head membranes. The assay results showed that (1) there is no significant difference between the potencies of natural (+)-alantrypinone and its synthetic racemate; (2) the amide NHs at the 2- and 18-positions are important for high activity; (3) there is a considerable drop in potency for compounds without an aromatic ring at the 16-position; and (4) a large substituent at the 3-position is detrimental to high activity.

  Using scandium triflate and microwaves, the direct double dehydrocyclization of anthranilate-containing tripeptides was achieved, affording the total syntheses of (i) quinazolino[3,2-a]benzodiazepinediones (1a–f), (ii) diazepino[2,1-b]quinazolinediones (2a–e), and (iii) pyrazino[2,1-b]quinazolinediones (3a–e) with good overall isolated yields (23–43%, 37–47% and 31–56%, respectively). Among the quinazolino[3,2-a]benzodiazepinediones synthesized, 1a (sclerotigenin), 1b (circumdatin F), and 1f (asperlicin C) are natural products.
