A general, facile, and efficient method is presented for the synthesis of 3-substituted 1,2,4-oxadiazoles from amidoximes and triethyl orthoformate. The procedure employs an iron(III) chloride/l-proline catalytic system and the 3-substituted 1,2,4-oxadiaz

N-Myristoyltransferase (NMT) is an essential eukaryotic enzyme and an attractive drug target in parasitic infections such as malaria. We have previously reported that 2-(3-(piperidin-4-yloxy)benzo[b]thiophen-2-yl)-5-((1,3, 5-trimethyl-1H-pyrazol-4-yl)meth

Page/Page column 63; 100; 101, (2013/06/27)
The invention provides compounds which inhibit N-myristoyltransferase and are selective for protozoal N-myristoyltransferase and, consequently suitable to treat microbial infections, including viral and fungal infections, and protozoan infections such as malaria, leishmaniasis and sleeping sickness.

1,2,4-Oxadiazole derivatives of phenylalanine: potential inhibitors of substance P endopeptidase

The synthesis and the biological activity of a series of benzyl or aryl substituted 1,2,4-oxadiazole derivatives of phenyl-alanine are described.A base-promoted intermolecular cyclization reaction was performed using racemic tert-butyloxycarbonyl protected phenylalanine methyl ester and an amidoxime.After deprotection of the amino function the compounds were evaluated for their affinity to rat brain NK1-receptors and as inhibitors of a specific substance P cleaving enzyme, substance P endopeptidase (SPE), isolated from human cerebrospinal fluid.The results indicate that several compounds are weak inhibitors of SPE.However, all compounds lacked appreciable NK1-receptor affinity.Keywords: 1,2,4-oxadiazoles / substance P endopeptidase / Phe-Phe mimetics / amide bioisostere / NK1-receptor affinity
Synthesis and Serotonergic Activity of 5-(Oxadiazolyl)tryptamines: Potent Agonists for 5-HT1D Receptors

The synthesis and 5-HT1D receptor activity of a novel series of 5-(oxadiazolyl)tryptamines is described.Modifications of the oxadiazole 3-substituent, length of the linking chain (n), and the amine substituents are explored and reveal a large binding pocket in the 5-HT1D receptor domain.Oxadiazole substituents such as benzyl are accommodated without loss of agonist potency or efficacy.The incorporation of polar functionality on a phenyl or benzyl spacer group results in a 10-fold increase in affinity and functional potency.Optimal 5-HT1D activity is observed when the heterocycle is conjugated with the indole and the benzyl sulfonamides 20t and 20u represent some of the most potent 5-HT1D agonist known.Replacement of O for S in the heterocycle leads to a further increase in potency.Deletion of oxadiazole N-2 does not reduce activity, suggesting the requirements for only one H-bond acceptor in this location.The selectivity of these compounds for 5-HT1D receptors over other serotonergic receptors is discussed.Sulfonamide 20t shows 1000-fold selectivity for 5-HT1D over 5-HT2, 5-HT1C, and 5-HT3 receptors and 10-fold selectivity with respect to 5-HT1A receptors.The functional activity of this series of compounds is studied and demonstrates high 5-HT1D receptor potency and efficacy comparable to that of 5-HT.
