This study aims to elucidate a systematic free-radical quenching ability of synthesized benzo[b]thiophene derivatives using in vitro assays and acrylamide induced oxidatively stressed model in zebrafish larvae.Antioxidant activity of the compounds was evaluated using in vitro methods. The toxicity of the compounds was evaluated in Madin-Darby Canine Kidney (MDCK) cell line and zebrafish embryos. Oxidative stress was generated by acrylamide (1 mM) in zebrafish larvae and treated with compounds to evaluate the in vivo antioxidant ability. Specific fluorescence dyes were used to detect ROS generation, lipid peroxidation, and cell death followed by gene expression using RT PCR. Density functional theory (DFT) and in silico pharmacokinetics were also studied.Compound BP and EP have a greater in vitro free radical scavenging ability. The maximum tolerated concentration (MTC) of the compounds in zebrafish larvae is 80 μM. The antioxidant system in zebrafish larvae was dysregulated due to acrylamide exposure and improvement was found while treating acrylamide exposed larvae with compounds 1-(3-hydroxybenzo[b]thiophen-2-yl) ethanone (BP) and 1-(3-hydroxybenzo[b]thiophen-2-yl) propan-1-one hydrate (EP). Compound BP and EP enhanced the SOD and CAT activity, reduced the ROS and lipid peroxidation level, thus decreasing cell death in zebrafish larvae. Compound BP and EP also improved the glutathione redox cycle by stabilizing glutathione-related gene expressions.Hydroxyl-containing compounds BP and EP are promising lead molecules for pathological conditions related to oxidative stress, which showed an attenuated effect on acrylamide-induced oxidative stress in zebrafish larvae by enhancing the glutathione redox cycle and enzymatic antioxidants. |
