Previously we described a novel series of pyrimidinol antioxidants and their structural optimization as potential therapeutic agents for neurodegenerative and mitochondrial disorders. Our initial lead compound was a potent antioxidant in vitro, but was subsequently found to exhibit poor stability to oxidative metabolism. The current study focused on balancing potency with metabolic stability through structural modification, and involved modifications at positions 2 and 4 of the pyrimidinol redox core, likely sites of oxidative metabolism. Eight new analogues have been prepared and their ability to suppress lipid peroxidation and reactive oxygen species (ROS), and to preserve mitochondrial membrane potential (Δψm) and support ATP production, has been investigated. The metabolic stability of the prepared compounds was also assessed in vitro using bovine liver microsomes to obtain preliminary insight on this class of compounds. This study revealed the complexity of balancing reasonable metabolic stability with efficient antioxidant properties. While a few analogues appear promising, especially in terms of metabolic stability, a 4-isopropoxy derivative conserved the favorable biological activity and exhibited good metabolic stability. The favorable metabolic stability conferred by the combination of the azetidine and isopropoxy moieties in analogue 6 makes this compound an excellent candidate for further evaluation.

The chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus, and it is the causative agent of chikungunya fever (CHIKF). Although it has re-emerged as an epidemic threat, so far there are neither vaccines nor pharmacotherapy available to prevent or treat an infection. Herein, we describe the synthesis and structure-activity relationship studies of a class of novel small molecule inhibitors against CHIKV and the discovery of a new potent inhibitor (compound 6a). The starting point of the optimization process was N-ethyl-6-methyl-2-(4-(4-fluorophenylsulfonyl)piperazine-1-yl)pyrimidine-4-amine (1) with an EC50 of 8.68 μM, a CC50 of 122 μM, and therefore a resulting selectivity index (SI) of 14.2. The optimized compound 6a, however, displays a much lower micromolar antiviral activity (EC50 value of 3.95 μM), considerably better cytotoxic liability (CC50 value of 260 μM) and consequently an improved SI of greater than 61. Therefore, we report the identification of a promising novel compound class that has the potential for further development of antiviral drugs against the CHIKV.
