Using an iterative structure-activity relationship driven approach, we identified a CNS-penetrant 5-(trifluoromethyl)-1,2,4-oxadiazole (TFMO, 12) with a pharmacokinetic profile suitable for probing class IIa histone deacetylase (HDAC) inhibition in vivo.

In order to find novel potential antifungal agrochemicals, a series of new 4-(1,2,4-oxadiazol-3-yl)-N-(4-phenoxyphenyl)benzamide derivatives 3a–j were designed, synthesized and characterized by their 1H-, 13C-NMR and HRMS spectra. Th

A new approach to the synthesis of 4and 3-(5-R-1,2,4-oxadiazol-3-yl)benzoic acids via a selective oxidation of 5-R-3-tolyl-1,2,4-oxadiazoles with air oxygen in the presence of a catalytic system based on cobalt acetate was suggested. This synthesis allowed us to obtain the products in higher yields and with shorter sequence of steps as compared to the known procedures.

Orally active GPIIb/IIIa antagonists: Synthesis and biological activities of masked amidines as prodrugs of 2-[(3S)-4-[(2S)-2-(4-amidinobenzoylamino)-3-(4-methoxyphenyl)propanoyl]-3- (2-methoxy-2-oxoethyl)-2-oxopiperazinyl]acetic acid

To improve the in vivo potency of the potent GPIIb/IIIa antagonist 2-[(3S)-4-[(2S)-2-(4-amidinobenzoylamino)-3-(4-methoxyphenyl)propanoyl]-3- (2-methoxy-2-oxoethyl)-2-oxopiperazinyl]lacetic acid (4), the amidino group was converted to an oxadiazole ring, thiadiazole ring of substituted amidoxime group. These groups were expected to be metabolized to an amidino group in vivo. The compounds synthesized were evaluated for their potency to inhibit the ex vivo adenosine 5′-diphosphate (ADP)-induced aggregation of guinea pig platelets. Among the compounds examined, the methoxycarbonyloxyamidine 8a exhibited the most potent ex vivo inhibitory activity with a fast onset and prolonged duration of action after oral administration.
Direct Synthesis of 5-Methyl-3-aryl-1,2,4-oxadiazoles from Aryl Aldehydes, Nitroethane, and Ammonium Acetate

The condensation of 2,5-dimethoxybenzaldehyde (1b) with nitroethane and ammonium acetate in glacial acetic acid has been found to give three diffrent products, depending on reactant ratio and reaction time.At an aldehyde:nitroethane:ammonium acetate ratio of 1:1.5:0.8 a normal Knoevenagel condensation occured, yielding 1-(2,5-dimethoxyphenyl)-2-nitropropene.At a reactant ratio of 1:3:2 (same reactant sequence), the primary product was 2,5-dimethoxybenzonitrile, and at a reactant ratio of 1:40:8, with extended reflux time, the major product was 3-(2,5-dimethoxyphenyl)-5-methyl-1,2,4-oxadiazole (8b).This last reaction served as a prototype for a new oxadiazole synthesis which was then extended to include six additional 5-methyl-3-aryl-1,2,4-oxadiazoles (8a,c-g; where aryl = Ph, 2,5-dimethoxyphenyl, 2,4-dichlorophenyl, m-chlorophenyl, p-tolyl, 3,5-dimethoxyphenyl, and p-carboxyphenyl), whose structures were assigned on the basis of 13C NMR characteristics of known reference compounds.Benzonitrile also reacted with excess nitroethane and ammonium acetate to yield 5-methyl-3-phenyl-1,2,4-oxadiazole (8a).The overall mechanism of oxadiazole formation is shown to be dependent on a preliminary reaction wherein the nitroalkane, in the presence of ammonium acetate and acetic acid, is first transformed into the corresponding alkanoic acid and hydroxylamine.Hydroxylamine then converts the aromatic aldehyde, via the intermediary nitrile, to the oxadiazoles following reactions of established precedent.
