Comparison between two classes of selective EP(3) antagonists and their biological activities

Two different series of very potent and selective EP(3) antagonists have been reported: a novel series of ortho-substituted cinnamic acids [Belley, M., Gallant, M., Roy, B., Houde, K., Lachance, N., Labelle, M., Trimble, L., Chauret, N., Li, C., Sawyer, N., Tremblay, N., Lamontagne, S., Carrière, M.-C., Denis, D., Greig, G. M., Slipetz, D., Metters, K. M., Gordon, R., Chan, C. C., Zamboni, R. J. Bioorg. Med. Chem. Lett.2005, 15, 527] and the acylsulfonamides of ortho-(arylmethyl)cinnamates. [(a) Juteau, H., Gareau, Y., Labelle, M., Sturino, C. F., Sawyer, N., Tremblay, N., Lamontagne, S., Carrière, M.-C., Denis, D., Metters, K. M. Bioorg. Med. Chem. 2001, 9, 1977; (b) Juteau, H., Gareau, Y., Labelle, M., Lamontagne, S., Tremblay, N., Carrière, M.-C., Denis, D., Sawyer, N., Metters, K. M. Bioorg. Med. Chem. Lett.2001, 11, 747] The structural differences between the two series, along with their biological activity in vivo, in vitro, and metabolism, are analyzed. Some of those compounds, including hybrids containing the best structural features of both series, possess K(i) as low as 0.6 nM on the EP(3) receptor.

Glucocorticoid receptor-binding site in the human immunodeficiency virus long terminal repeat.

Previous reports (P. D. Katsanakis, C. E. Sekaris, and D. A. Spandidos, Anticancer Res. 11:381-383, 1991; J. Laurence, M. B. Sellers, and S. K. Sikder, Blood 74:291-297, 1989; R. Miksicek, A. Heber, W. Schmid, U. Danesch, G. Posseckert, M. Beato, and G. Schutz, Cell 46:283-290, 1986) have suggested the existence of a glucocorticoid response element in the long terminal repeat of human immunodeficiency virus (HIV) type 1. This study demonstrated a sequence-specific interaction of the glucocorticoid receptor DNA-binding domain with the previously predicted HIV glucocorticoid response element. This interaction may be relevant to the steroid responsiveness of HIV (P. A. Furth, H. Westphal, and L. Hennighausen, AIDS Res. Hum. Retroviruses 6:553-560, 1990; J. Laurence, M. B. Sellers, and S.

Taxonomy and preliminary phylogeny of the parasitic genus Apocephalus, subgenus Mesophora (Diptera: Phoridae)

Abstract. The species of Apocephalus , subgenus Mesophora , are revised and twenty-eight species are recognized, including the following twenty-two new to science: from the Nearctic Region A. brunnipes, A. gemursus, A. pristinus, A. setialvus and A. unitarsus , and from the Neotropical Region A. absentis, A. adustus, A. anfractus, A. angustistylus, A. bisetus, A. brevicercus, A. curtus, A. gracilis, A. hansoni, A. leptotarsus, A. longistylus, A. micrepelis, A. moraviensis, A. prolatus, A. trisetus, A. tritarsus and A. truncaticercus. Additionally, three species known only from female specimens are described but not formally named. A lectotype is designated for A. mortifer Borgmeier, and immature stages of A. borealis, A. antennatus and A. mortifer are described. Unlike larvae of other Apocephalus species, all of which are parasites of ants (Hymenoptera: Formicidae), those of Mesophora species are parasites of various other hosts.

A revision of male ants of the Malagasy Amblyoponinae (Hymenoptera: Formicidae) with resurrections of the genera Stigmatomma and Xymmer

In a male-based revision of ants of the subfamily Amblyoponinae from the Southwest Indian Ocean islands (SWIO: Comoros, Madagascar, Mauritius, Mayotte, Reunion, and Seychelles), we explore and reconsider male morphological characters that distinguish genera within the group. Our investigation redefines Amblyopone Erichson sensu Brown (1960), here referred to as Amblyopone sensu lato, into three genera: Xymmer Santschi stat. rev.,Amblyopone sensu stricto, Stigmatomma Roger stat. rev. All species names under Amblyopone s. l. reassign into Xymmer and Amblyopone s. s., which are small, well-defined genera, and Stigmatomma, a large group with a generic delimitation that still needs further refinement. Based on a study of male mandible characters and our scenario for mandibular evolution of the worker caste within Amblyopone s. l, we conclude that Amblyopone s. s. nests outside of XMAS (Xymmer+Mystrium+Adetomyrma+Stigmatomma) clade. The following names are transferred from Amblyopone s. l. to Xymmer as comb. rev.: muticus. The following names are transferred from Amblyopone s. l. to Stigmatomma as comb. rev.: amblyops, armigerum, bellii, bierigi, bruni, celata, chilense, denticulatum, elongatum, emeryi, feae, impressifrons, luzonicum, minuta, normandi, oregonense, pallipes, quadratum, reclinatum, rothneyi, santschii, saundersi, silvestrii, zwaluwenburgi; as comb. nov.: agostii, annae, besucheti, boltoni, caliginosum, cleae, crenatum, degeneratum, egregium, electrinum, eminia, exiguum, falcatum, ferrugineum, fulvidum, gaetulicum, gingivalis, glauerti, gnoma, gracile, groehni, heraldoi, lucidum, lurilabes, monrosi, mystriops, noonadan, octodentatum, ophthalmicum, orizabanum, papuanum, pertinax, pluto, punctulatum, rubiginoum, sakaii, smithi, trigonignathum, trilobum, wilsoni, zaojun, and testaceum. A male-based key to the genera of Malagasy amblyoponine ants, their diagnoses, and a discussion of the evolution of the morphological character of males in the subfamily are given, and the distinguishing characters of each are illustrated. In addition, our results predict that Paraprionopelta belongs in the XMAS clade and that Concoctio should have males with two mandibular teeth.

Transmission of wheat striate virus by the eggs of the vectorCalligypona pellucida Fabr

Персистентная природа вируса стерилйности и карликовостн овса (ВСКО) и вируса полосатости пшеницы (ВПП) изучалась также в опыте с личинками вектораCalligypona pellucida F. происходящими нз яиц, в условиях исключающих возможность их контаминации сосанием на зараженных вирусом растениях. Яйца происходили от самок из популяции, у которой в преодшествующем теете установелено 14,4% неинфекционных особей, 61,2% зараженных ВСКО, 1,9% зараженных ВПП и 22,5% зараженных одновременно ВСКО и ВПП. При индивидуальном несколько месяцев длившемся изучении инфекционности контрольных личинок, которые никогда не имели возможности сосать на зараженных вирусом растениях, ни одна личинка не перенесла ВСКО, несмотря на то, что им их родители в высокой степени (83,7%) заражены. Наоборот, 14,9% насекомых перенесло ВПП, которым их родители заражены в меньшей степени (24,4%). Опытные личинки, следовательно, приобрели ВПП от родительских самок трансовариально и в высокой степени. Это замечательное снойство позволило отличить ВПП от ВСКО, которые в Чехословакии выступают часто вместе. Личинки, которые прошли приобретающим сосанием на овсе вараженном ВПП, проявляли по сравнению с контрольными повышсние инфективиости на 61,6% носле происшествия срока, отвечающего 26–34-хдневной циркуляции вируса в теле нереносчика и на 98,2% после циркуляционного срока в 40–51 дней. В теле вектора, новиюимому, не имеет места интерферренция между ВСКО и ВПП, так как заражение цикады одним вирусом, повидиному, не являестя препятствием се заражению друтим. Перекрестной защиты между ВСКО и ВПП в растениях—хозяевах или не существует или она незначительна, так как растения могут страдать от обенх вирусов одновременно. Признаки одного вируса, однако, могут в разной стопени, перекрываться симптомами вируса другого.
