TY - JOUR T1 - IN VITRO ANTIOXIDANT ACTIVITY OF NOVEL 4-HYDROXY-1-METHYL-3-(3-SUBSTITUTED)-4,5-DIHYDROISOXAZOL-5-YL)QUINOLIN-2(1H)-ONE DERIVATIVES A1 - Arunadevi Parlapalli and Sarangapani Manda JF - Pharmacophore JO - Pharmacophore SN - 2229-5402 Y1 - 2015 VL - 6 IS - 5 SP - 243 EP - 248 N2 - A series of novel 4-Hydroxy-1-methyl-3-(3-substituted)-4,5-dihydroisoxazol-5-yl)quinolin-2(1H)-one derivatives were synthesized from chalcones (α, β-unsaturated compounds) well known compounds to exhibit antioxidant activities. All the synthesized compounds were characterized by spectral and analytical data and were evaluated for antioxidant activity by DPPH method using standard Ascorbic acid. All the compounds are known to exhibit antioxidant activity. Among them, compound (5f) exhibited the IC50 = 7.2 μM, standard (IC50 = 5.85 μM) UR - https://pharmacophorejournal.com/article/in-vitro-antioxidant-activity-of-novel-4-hydroxy-1-methyl-3-3-substituted-45-dihydroisoxazol-5-ylquinolin-21h-one-derivatives ER -
