CYP2C9 and ABCG2 polymorphisms as risk factors for developing adverse drug reactions in renal transplant patients taking fluvastatin: a case-control study.

Aim: To investigate whether an association exists between fluvastatin-induced adverse drug reactions (ADRs) and polymorphisms in genes encoding the metabolizing enzyme CYP2C9 and the drug transporter ABCG2 in renal transplant recipients (RTRs).

Materials & Methods: Fifty-two RTRs that experienced fluvastatin ADRs and 52 controls matched for age, gender, dose of fluvastatin and immunosuppressive use were enrolled in the study. Genotyping for CYP2C9*2, *3 and ABCG2 421C>A variants was performed by real-time PCR.

Fenoprofen and ketoprofen amides as potential antitumor agents.

Following numerous experimental observations that various non-steroidal anti-inflammatory drugs have antitumor potentials, a series of fenoprofenamides (1a-g) and ketoprofenamides (2a-c) was tested on proliferation of different human tumor cell lines and normal human fibroblasts in vitro. Fenoprofen and ketoprofen showed modest antiproliferative activity, whereas the growth inhibitory activity of the tested amides clearly demonstrates that the substituents linked by an amide bond are essential for the significantly stronger cytostatic activity, probably because of a greater lipophilicity and/or better cell uptake. Additionally, it was shown that the most active derivatives (1d and 2a) induced cell cycle arrest at the G1 phase, as well as apoptosis.
