9-(3-Mesityl-4,5-dihydroisoxazol-5-yl) homo-N-nucleosides were prepared from the 1,3-dipolar cycloaddition reactions of mesityl nitrile oxide with 9-allyl derivatives of 6-chloropurine, 6-piperidinylpurine, 6-morpholinylpurine, 6-pyrrolidinylpurine, and 6-N,N-dibenzoyladenine. The new compounds were tested in vitro for their ability: (i) to interact with 1,1-diphenyl-2-picryl-hydrazyl (DPPH) stable
由1,3-二异丁腈腈与6-氯嘌呤,6-哌啶基嘌呤的9-烯丙基衍生物的1,3-偶极环加成反应制备了9-(3-Mesityl-4,5-dihydroisoxazol-5-yl)homo- N -nucleosides。 ,6-吗啉基嘌呤,6-吡咯烷基嘌呤和6- N,N-二苯甲酰腺嘌呤。在体外测试了这些新化合物的能力:(i)与1,1-二苯基-2-picryl-肼基(DPPH)稳定的自由基相互作用,(ii)抑制脂质过氧化,(iii)清除超氧化物。阴离子,(iv)抑制大豆脂氧合酶的活性,(v)抑制体外凝血酶。他们中的大多数被发现是有效的凝血酶抑制剂,并抑制体外脂质过氧化。大多数化合物显示出明显的脂氧合酶抑制活性。
