Efficacy of 5-(2-aroyl)aryloxy methyl-2-phenyl-1,3,4-oxadiazoles as antibacterial and antifungal agents

Research and development of potent and effective antimicrobial agents represent one of the most important advances in therapeutics; the main aim of these efforts is not only control the serious infections, but also prevention and treatment of some infectious complications of other therapeutic modalities. A series of 5-(2-aroyl)aryloxy methyl-2-phenyl-1,3,4-oxadiazoles were screened for their antibacterial and antifungal activities. Anti-bacterial activity against B. cereus, S. aureus, B. subtilis, S. aureus (MRSA), E. aerogenes, M. luteus, K. pneumonia, P. aeruginosa, S. typhimurium, E. coli, paratyphi-B, P. vulgaris bacterial strains and anti-fungal activity against C. albicans, A.niger, F.solani, A.flavus, B.cinerea, C.krusei, M. pachydermatis, C.parapsilosis, F.moniliforme, C.gloeosporioides fungal strains were carried out. The bioassays indicated that most of the synthesized compounds showed potential antibacterial and anti-fungal activity

Synthesis and anti-inflammatory activity of 2-aryloxy methyl oxazolines

A series of potential biologically active 2-aryloxy methyl oxazolines 3a–n have been synthesized from substituted hydroxybenzenes 1a–n with good chemical yield. The compounds 3a–n were screened for their anti-inflammatory, ulcerogenic, cyclooxygenase activities and also for their acute toxicity. The potency of the compounds was compared with that of the standard drugs, aspirin and phenyl butazone. The outcome indicates that compounds 3b (48.2), 3h (48.5) and 3l (46.5) offered significant anti-inflammatory activity with low ulcerogenic activity than the standard drugs

Synthesis of 2-(2-aroylaryloxy)methyl-oxazolines as potent analgesic and anti-inflammatory agents

The synthetic strategies and characterization of some novel benzophenone derivatives carrying oxazoline ring are described using microwave irradiation technique. The compounds 2a-h, 3a-h and 4a-h were screened for their analgesic, anti-inflammatory, ulcerogenic, cyclooxygenase activities and acute toxicity. The results revealed that halo compounds 4a (48.3%), 4c (45.4%) and 4f (40.2%) displayed significant anti-inflammatory activity with low ulcerogenic activity in comparison with that of the standard drugs, aspirin (35.3%) and phenyl butazone (35.5%
