  Synthesis and histamine H2 agonistic activity of arpromidine analogues: replacement of the pheniramine-like moiety by non-heterocyclic groups

  摘要：

  Analogues of the potent histamine H-2 agonist arpromidine, characterized by non-heterocyclic groups (phenyl, cyclo-hexyl, alkyl) instead of the pheniramine-like portion, were prepared and tested for their H-2 agonistic and H-1 antagonistic activity in the isolated guinea pig right atrium and ileum, respectively. In the diphenylpropylguanidine series an increase in H-2 agonistic potency resulted from mono- or difluorination at one or both phenyl rings in the meta and/or para position (pD2 less-than-or-equal-to 7.75 vs pD2 = 7.15 for the unsubstituted parent compound). Compounds chlorinated at both phenyl rings were considerably less potent. Highest combined H-2 agonistic/H-1 antagonistic potency was found in the 4-fluorophenyl series. The arpromidine analogue with cyclohexyl and methyl group instead of phenyl and pyridine ring proved to be 30 times more potent than histamine in the atrium. The H-1 antagonistic potency in cyclohexyl compounds was lower than in the diaryl series. Thus, aromatic rings appear not to be required for high H-2 agonistic potency but are useful for combined H-2 agonistic/H-1 antagonistic activity.

  Regioselective addition of pyrrole to methyl 3-aryl-2-cyanoacrylates was achieved, in high yields, with copper(II) triflate as the catalyst in toluene. C-Alkylated pyrroles afforded novel pyrrolizin-3-ones, in good to high yields and high diastereomeric ratio by an intramolecular cyclization reaction under mild reaction conditions.

  α-proton in the cyclization process. The acidity dependence of the cyclization reactions and 13C NMR studies of a model compound, methyl cyanoacetate, in various acidic media were consistent with the involvement of the O,N-diprotonated dication of methyl cyanoacetate, a distonic dication, in strong acid, and this is considered to be the de facto electrophile in the present cyclization reaction of arylcyanopropionates

  A core–shell structured nanocomposite, with hexagonal Mg–Al mixed oxide nanoplates derived from LDHs as the inner core and Al-containing mesoporous silica as the outer shell, was prepared using an inorganic, low cost and simple route. The mesoporous silica shell was not only capable of protecting the MgAl-LDO core, but also offered a high surface area for the derivation of functional acid catalytic

The diastereoselectivity was affected by the halogen of the catalyst and electron‐withdrawing groups on the cyanoalkene. The transformation of the spirohexane was carried out to afford a cyclopentanoid which has been prepared only by a transition metal catalyst.
