Chemically synthesized sugar-cholestanols possess a preferential anticancer activity involving promising therapeutic potential against human esophageal cancer.

The understanding of the cell signaling pathways and the molecular events leading to cell death of cancer cells will provide in-depth perspective into the identification and development of potent anticancer agents. A balance between cell proliferation and cell death has been raised as a rational target for the management of malignant tumors. In the present study, the authors demonstrated that chemically synthesized sugar-cholestanols consisting of GlcNAcbeta-, Galbeta- and GlcNAcbeta1,3Galbeta-cholestanols exerted a strong inhibiting activity against cell proliferation of esophageal cancer cells, but cholestanol itself did not show such an activity against the same cancer cells at all.

The pharmacokinetics of toborinone in subjects with congestive heart failure and concomitant renal impairment and/or concomitant hepatic impairment.

The pharmacokinetics of toborinone was studied in subjects with congestive heart failure (CHF) and concomitant renal and/or hepatic disease. At the time of admission, subjects were grouped based on estimated creatinine clearance and serum bilirubin. Glomerular filtration rate was assessed using iothalamate clearance.

The effects of concomitant administration of theophylline and toborinone on the pharmacokinetics of both compounds in poor and extensive metabolizers via CYP2D6.

This study investigated the effects of the concomitant administration of theophylline and toborinone on the pharmacokinetics of both compounds in poor and extensive metabolizers via CYP2D6. In period 1, a single dose of 3.5 mg/kg theophylline was administered orally.
