Figures & data

Figure 1. The Pharmacokinetics of Botryllamide G in Mice. The maximum soluble dose (13 mg/kg) of botryllamide G was administered to mice (n = 3 for each timepoint) via IV tail vein injection. Botryllamide G demonstrate biphasic elimination, which involves rapid distribution into tissues and a plasma exposure that quickly dropped below the in vitro IC50 of 6.9 µM. Error bars represent mean standard deviation.
