Tremorgenic neuromycotoxicosis in 2 dogs ascribed to the ingestion of penitrem A and possibly roquefortine in rice contaminated with Penicillium crustosum.
    Journal of the South African Veterinary Association, 2002, Volume: 73, Issue:4

    Two dogs developed alarming tremorgenic nervous stimulation shortly after ingesting discarded rice that had been forgotten in a refrigerator for an undetermined period and that was covered with a grey-green mould. Both dogs exhibited vomition followed by slight salivation, tremors and ataxia and 1 showed such severe agitation and seizures that it necessitated anaesthesia with thiopentone followed, on recovery, by xylazine. The other dog was only sedated with xylazine. They made an uneventful recovery. The rice vomitus yielded a pure culture of Penicillium crustosum. On chemical analysis it was negative for organochlorine, organophosphor and carbamate insecticides, as well as for strychnine, but contained 2.6 microg/g of the mycotoxins penitrem A as well as 34 microg/g of roquefortine as determined by LC-MS and confirmed by MS-MS. This is the 1st South African case of naturally occurring penitrem A toxicosis and also the 1st case where quantification of the levels of mycotoxins in dog vomitus is reported. The tremorgenicity of roquefortine and its contribution towards this syndrome, is questioned.

Effects of a 5-HT1A receptor agonist on acute and delayed cyclophosphamide-induced vomiting.
    European journal of pharmacology, 1997, Dec-11, Volume: 340, Issue:2-3

    LY228729 [(-)-4(dipropylamino)-1,3,4,5-tetrahydrobenz-[c,d]indole-6-carboxa mide]], an agonist at the 5-HT1A subtype of 5-HT receptor, was studied as an antiemetic in pigeons dosed with a highly emetic oncolytic agent, cyclophosphamide. An intramuscular injection of 0.32 mg/kg of LY228729 administered 15 min prior to the intravenous injection of 200 mg/kg of cyclophosphamide totally prevented the acute emetic response induced by cyclophosphamide. When used as a rescue therapy in a separate group of pigeons, LY228729 (0.32 mg/kg, i.m.) prevented further emetic episodes when it was administered after vomiting had already been induced by cyclophosphamide. Injections of LY228729 given at intervals over the next 2 d also attenuated the delayed emetic response induced by cyclophosphamide. LY228729 appears to be a broad spectrum antiemetic agent that is effective against the anticipatory, the acute and the delayed stages of emesis induced by oncolytic agents.

Comparison of the antiemetic effects of a 5-HT1A agonist, LY228729, and 5-HT3 antagonists in the pigeon.
    Pharmacology, biochemistry, and behavior, 1995, Volume: 52, Issue:3

    Vomiting may be induced by a variety of agents such as drugs, oncolytics, and provocative motion, as well as being conditioned to occur to environmental stimuli. Such emesis has recently been shown to be blocked by agonists at the 5-HT1A subtype of serotonin receptor. The antiemetic effects of LY228729 [(-)-4-(dipropylamine)-1,3,4,5-tetrahydrobenz-(c,d)indole-6- carboxamide], a 5-HT1A receptor agonist, were tested and compared to the antiemetic effects of the 5-HT3 receptor antagonists ondansetron, tropisetron, and MDL 72222 (3-tropanyl-3,5-dichlorobenzoate). The emetic stimuli tested are known to be blocked by 5-HT3 antagonists in species other than the pigeon. In the pigeon, LY228729 totally abolished vomiting induced by fully emetic doses of cisplatin (10 mg/kg), ipecac (3 ml/kg), emetine (10 mg/kg), and a 5-HT3 agonist, m-(chlorophenyl)-biguanide (1.25 mg/kg). MDL 72222 blocked ipecac-induced vomiting in a dose-related manner and was partially effective in attenuating cisplatin-induced emesis. Ondansetron and tropisetron were partially effective in blocking emetine- and mCPBG-induced vomiting. Ondansetron exhibited an intrinsic emetic response that could not be blocked by MDL 7222, but which was eliminated by LY228729. It was concluded that 5-HT1A agonists are more effective in the pigeon than are 5-HT3 antagonists against these types of emetic stimuli. These results broaden the range of emetic stimuli that are blocked by 5-HT1A agonists in the pigeon.

[Clinical experiences with the prolactin-inhibiting serotonin antagonist metergoline].
    Wiener klinische Wochenschrift, 1983, Jun-24, Volume: 95, Issue:13

    20 puerperal women who did not wish to breast feed their infants were treated with the serotonin antagonist metergoline. In 19 cases effective suppression of puerperal lactation was achieved by the administration of metergoline without the side effects or signs of intolerance. Of 9 women with hyperprolactinaemic amenorrhoea treated with metergoline the raised prolactin level was lowered, followed by menstruation in 7 patients. Ovulation even occurred in 5 of these women. One patient had to discontinue therapy due to intolerance. in normoprolactinaemic amenorrhoea regular menstruation reappeared in 4 out of 5 women; 2 patients even ovulated.

Synthesis and central dopaminergic activities of (+/-)-hexahydro-7H-indolo[3,4-gh][1,4]benzoxazine derivatives [(+/-)-9-oxaergolines].
    Journal of medicinal chemistry, 1983, Volume: 26, Issue:4

    The synthesis and biological activities of a series of (+/-)-hexahydro-7H-indolo[3,4-gh][1,4]benzoxazine derivatives [(+/-)-trans-9-oxaergolines] with central dopamine (DA) agonist properties are described. The compounds were prepared from [2aRS-(2a alpha,4 beta,5 alpha)]-4-amino-1,2,2a,3,4, 5-hexahydro-1-(phenylmethyl)benz[cd]indol-5-ol (6b) by alkaline cyclization of the corresponding N-chloracetamide 7b, followed by reduction of the amido group [5aRS-(5a alpha, 6a beta, 10a alpha)]-4,5,5a,6,6a,7,9, 10a-octahydro-4-(phenylmethyl)-7H-indolo[3,4-gh][1,4]benzoxazin-8-one (8b) with LiAlH4. After debenzylation of the resulting amine 9a, the indoline ring of [5aRS-(5a alpha, 6a beta, 10a alpha)]-4,5,5a,6,6a,8,9, 10a-octahydro-7H-indolo[3,4-gh][1,4 ]benzoxazine (10a) was dehydrogenated with MnO2 to give (+/-)-trans-9-oxaergoline (11a), which can be alkylated on the nitrogen (11b,c and 12) and brominated in position 2 (13a,b). The compounds were examined in vitro for their ability to bind to DA receptors and to inhibit prolactin (PRL) secretion in pituitary cells in culture, in vivo both for their DA stimulant effects at the striatal level (circling in 6-OHDA-lesioned animals, DA turnover, and stereotypy) and inhibitory effects on plasma PRL levels in rats, and for their emetic effects in dogs. Most of the tested compounds were active in these tests, and the potency of (+/-)-trans-6-n-propyl-9-oxaergoline (11c) was comparable to that of pergolide mesylate.
