We have discovered two related chem. series of nonpeptide urotensin-II (U-II) receptor antagonists based on piperazino-phthalimide (5 and 6) and piperazino-isoindolinone (7) scaffolds. These structure types are distinctive from those of U-II receptor antagonist series reported in the literature. One of the antagonists exhibited single-digit nanomolar potency in rat and human cell-based functional assays, as well as strong binding to the human U-II receptor. In advanced pharmacol. testing, one of the antagonists blocked the effects of U-II in vitro in a rat aortic ring assay and in vivo in a rat ear-flush model. A discussion of U-II receptor antagonist pharmacophores is presented, and a specifically defined model is suggested from tricycle compound, which has a high degree of conformational constraint.

A series of substituted isoindolinone ureas was prepared and evaluated for enzymic and cellular inhibition of KDR kinase activity. Several of these analogs, such as I, are potent inhibitors of KDR both enzymically (<50 nM) and cellularly (≤100 nM). A 3D KDR/CDK2/MAP kinase overlay model with several structurally related tyrosine kinase inhibitors was used to predict the binding interactions of the isoindolinone ureas with the KDR active site.

Troeger, Armin; Svensson, Glenn P.; Galbrecht, Hans-Martin; Twele, Robert; Patt, Joseph M.; Bartram, Stefan; Zarbin, Paulo H. G.; Segraves, Kari A.; Althoff, David M.; von Reuss, Stephan; Raguso, Robert A.; Francke, Wittko published the artcile< Tetranorsesquiterpenoids as Attractants of Yucca Moths to Yucca Flowers>, SDS of cas: 1530-33-2, the main research area is Tegeticula Yucca flower tetranorsesquiterpenoids attractants; DMNT-derivatives; Floral scent; Pollinator attraction; Structure elucidation; Tetranorsesquiterpenoids; Total synthesis; Yucca.

The obligate pollination mutualism between Yucca and yucca moths is a classical example of coevolution. Oviposition and active pollination by female yucca moths occur at night when Yucca flowers are open and strongly scented. Thus, floral volatiles have been suggested as key sensory signals attracting yucca moths to their host plants, but no bioactive compounds have yet been identified. In this study, we showed that both sexes of the pollinator moth Tegeticula yuccasella are attracted to the floral scent of the host Yucca filamentosa. Chem. anal. of the floral headspace from six Yucca species in sections Chaenocarpa and Sarcocarpa revealed a set of novel tetranorsesquiterpenoids putatively derived from (E)-4,8-dimethyl-1,3,7-nonatriene. Their structure elucidation was accomplished by NMR anal. of the crude floral scent sample of Yucca treculeana along with GC/MS anal. and confirmed by total synthesis. Since all these volatiles are included in the floral scent of Y. filamentosa, which has been an important model species for understanding the pollination mutualism, we name these compounds filamentolide, filamentol, filamental, and filamentone. Several of these compounds elicited antennal responses in pollinating (Tegeticula) and non-pollinating (Prodoxus) moth species upon stimulation in electrophysiol. recordings. In addition, synthetic (Z)-filamentolide attracted significant numbers of both sexes of two associated Prodoxus species in a field trapping experiment Highly specialized insect-plant interactions, such as obligate pollination mutualisms, are predicted to be maintained through “”private channels”” dictated by specific compounds The identification of novel bioactive tetranorsesquiterpenoids is a first step in testing such a hypothesis in the Yucca-yucca moth interaction.

In the presence of Cu(OTf)2 and a nonracemic bis(oxazoline), terminal and 1,1-disubstituted and 1,2-disubstituted alkenols such as I underwent enantioselective intramol. hydroalkoxylation with 1,4-cyclohexadiene as a reducing agent and either MnO2 or Ag2CO3 as oxidant in PhCF3 to yield nonracemic cyclic ethers such as II. Tetrahydrofurans, phthalans, isochromans, and morpholines were prepared from 4- and 5-alkenols using this method; the substrate scope is complementary to existing enantioselective alkene hydroalkoxylations and is broad with respect to substrate backbone and alkene substitution. The method was used for an enantioselective preparation of the antifungal insecticide furametpyr. A polar/radical mechanism involving enantioselective oxycupration followed by homolysis of the copper-carbon bond and hydrogen atom transfer is proposed.
