A Simple, Practical and Efficient Method for the Synthesis of New Disubstituted 1,3,4-oxadiazoles
Reactions of N-isocyaniminotriphenylphosphorane with α- chloroketones in the presence ofaromatic carboxylic acids proceed smoothly at room temperature and in neutral conditions toafford new disubstituted 1,3,4-oxadiazole derivatives in high yields.
متن کاملIdentification of 1, 2, 5-Oxadiazoles as a New Class of SENP2 Inhibitors Using Structure Based Virtual Screening
Small ubiquitin like modifier (SUMO) specific proteases (SENPs) are cysteine proteases that carry out the proteolytic processing of SUMO from its pro form as well as the deconjugation of SUMO from substrate proteins. SENPs are attractive targets for drug discovery due to their crucial role in the development of various diseases. However, the SENPs inhibitor discovery efforts were limited, and o...
متن کاملSynthesis and Pharmacological Activity Evaluation of Oxadiazoles Containing Substituted Dihydropyrimidinone and Chloroquinoline Moities
In the present paper, synthesis of new series of 1,3,4oxadiazole derivatives incorporating substituted dihydropyrimidinone and chloroquinoline moieties 4(a-j) has been reported. All the synthesized compounds were characterized by FTIR, 1 H NMR and Mass spectroscopy. The compounds were screened for their in vivo anti-inflammatory activity by the carrageenan induced rat paw edema method and in vi...
متن کاملToxicological Evaluation of Anti-Scrapie Trimethoxychalcones and Oxadiazoles.
An altered form of the cellular prion protein, the PrPScor PrPRes, is implicated in the occurrence of the still untreatable transmissible spongiform encephalopathies. We have previously synthesized and characterized aromatic compounds that inhibit protease-resistant prion protein (PrPRes) accumulation in scrapie-infected cells. These compounds belong to different chemical classes, including acy...
متن کاملSynthesis of fluorinated oxadiazoles with gelation and oxygen storage ability.
A new family of fluorinated low molecular weight (LMW) gelators has been synthesized through SNAr substitution of 5-polyfluoroaryl-3-perfluoroheptyl-1,2,4-oxadiazoles with glycine ester. The obtained compounds give thermal and pH-sensitive hydrogels or thermo-reversible organogels in DMSO. Oxygen solubility studies showed the ability to maintain high oxygen levels in solution and in gel blend w...
