| Sampleprep Summary: | 5 × 106 A549 cells were treated with or without DRB18 for 48 hours. After treatment, cells were washed twice with deionized water and polar metabolites were then extracted with cryogenically cold 80% methanol/water mixture. LC-MS grade water, methanol, and acetonitrile (Fischer Scientific, PA, USA) were used. Methanol-extracted samples were then sonicated in cycles of sonication phase and rest phase for 10 minutes (5 second sonication phase and 10 seconds halt). The samples were then centrifuged at 13,000 rpm for 10 minutes and supernatant was then collected. Supernatants collected from in vitro and in vivo extraction were then lyophilized. Briefly, the supernatant was then lyophilized by using a speed vaccum evaporator. The samples were then dissolved into a mixture of acetonitrile/water (1:1; v/v). |
