HYDRAZONE DERIVATIVE

A compound represented by the following formula (I): wherein R1 represents hydrogen, aryl which may have a substituent, a saturated or unsaturated 5- to 7-membered heterocyclic group which may have a substituent, etc.; R2 represents hydrogen, aryl which may have a substituent, a saturated or unsaturated 5- to 7-membered heterocyclic group which may have a substituent, etc.; R3 represents hydrogen, etc.; Ar represents a divalent group derived from aromatic hydrocarbon, etc.; X represents a single bond, linear or branched alkylene having from 1 to 3 carbon atoms which may have a substituent, etc.; and G represents halogen, a saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group which may have a substituent, a saturated or unsaturated 5- to 7-membered heterocyclic group which may have a substituent, etc., a salt thereof or a solvate thereof; and an agent for inhibiting aggregation and/or deposition of an amyloid protein or an amyloid-like protein, which comprises the compound, a salt thereof or a solvate thereof

Substituted indolylpropyl-piperazine derivatives as 5-HT1D α agonists

A class of 1-[3-(1H-indol-3-yl)propyl]-4-(2-phenylethyl)piperazine derivatives, substituted at the 5-position of the indole nucleus by a five-membered heteroaromatic moiety, on one or other of the ethylene carbon atoms of the phenethyl moiety by halogen, trifluoromethyl, alkyl, hydroxyalkyl or alkoxyalkyl, and optionally on the phenyl ring of the phenethyl moiety by halogen, trifluoromethyl, alkoxy or an oxazolidinone group and optionally by one or two further substituents, are selective agonists of 5-HT1 -like receptors, being potent agonists of the human 5-HT1D α receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1D α receptor subtype relative to the 5-HT1D β subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.

3-[3-(piperidin-1-yl)propyl]indoles as highly selective h5-HT(1D) receptor agonists

Several 5-HT(ID/1B) receptor agonists are now entering the marketplace as treatments for migraine. This paper describes the development of selective h5-HT(1D)receptor agonists as potential antimigraine agents which may produce fewer side effects. A series of 3-[3-(piperidin-1-yl)propyl]indoles has been synthesized which has led to the identification of 80 (L-772,405), a high- affinity h5-HT(1D) receptor full agonist having 170-fold selectivity for h5- HT(1D) receptors over h5-HT(1B) receptors. L-772,405 also shows very good selectivity over a range of other serotonin and nonserotonin receptors and has excellent bioavailability following subcutaneous administration in rats. It therefore constitutes a valuable tool to delineate the role of h5-HT(1D) receptors in migraine. Molecular modeling and physical properties have been utilized to postulate the binding conformation of these compounds in the receptor cavity.

Imidazole, triazole and tetrazole derivatives

A class of substituted imidazole, triazole and tetrazole derivatives of formula (I), wherein the broken circle represents two non-adjacent double bonds in any position in the five-membered ring; two, three or four of V,W,X,Y and Z represent nitrogen and the remainder represent carbon provided that, when two of V,W,X,Y and Z represent nitrogen and the remainder represent carbon, then the said nitrogen atoms are in non-adjacent positions within the five-membered ring; E represents a bond or a straight or branched alkylene chain containing from 1 to 4 carbon atoms; F represents a group of formula (lI); U represents nitrogen or C--R2 ; B represents oxygen, sulphur or N--R3 ; are selective agonists of 5--HT1 -like receptors and are therefore useful in the treatment of clinical conditions, in particular migraine and associated disorders, for which a selective agonist of these receptors is indicated.
