标题:Synthesis And Biological Screening Of 2-Substituted 5,6-Dihydro-5-Oxo-4H-1,3,4-Oxadiazine-4-Propanenitriles And Of Their Intermediates
摘要:To Evaluate The Effect Of Substituents On Biological Activities Of Electron-Rich N-Containing Heterocycles,The Variably 2-Substituted 5,6-Dihydro-5-Oxo-4H-1,3,4-Oxadiazine-4-Propanenitriles 26-33 Were Synthesized And Evaluated For Antibacterial,Antifungal,And Enzyme-Inhibition Activities. The Target Compounds Were Obtained From Alkyl 4-Or 3-Hydroxy Benzoates 1 And 2,Respectively,And From Methyl Indoleacetate 3. The Phenolic Oh Group Of Benzoates I And 2 Were Substituted With P-Toluenesulfonyl (--> 4 And 5),Benzoyl ( 6 And 7),And Benzyl Groups ( 8 And 9) And Then Converted To 5,6-Dihydro-5-Oxo-4H-1,3,4-Oxadiazine-4-Propanenitriles. To Establish Structure-Activity Relationships (Sar),A Pharmacological Screening Of The Intervening Intermediates Was Also Conducted,Which Revealed That The Intermediate Hydrazide 11 Possesses Significant Antimicrobial And Mao-A Inhibiting Properties And Intermediates 12,24,28,And 29 Appreciable Antifungal Activities. Compound 7 Inhibits A-Chymotrypsin.
