Chromatographic lipophilicity as a predictor of antiproliferative activity of 17-picolyl and 17-picolinylidene androstane derivatives toward prostate cancer
Lipophilicity is a molecular parameter widely used in estimation of biological and environmental behavior of many substances (1-3).
Nonclinical and pharmacokinetic assessments to evaluate the potential of tedizolid and linezolid to affect mitochondrial function
Prolonged treatment with the oxazolidinone linezolid is associated with myelosuppression, lactic acidosis, and neuropathies, toxicities likely caused by impairment of mitochondrial protein synthesis (MPS). To evaluate the potential of the novel oxazolidinone tedizolid...
