Tamoxifen (TAM) is a widely used drug in the prophylaxis and treatment of breast cancer. TAM is metabolized to the more active 4-hydroxytamoxifen (4-OH-TAM) and endoxifen by cytochrome P450 (CYP) mainly CYP2D6 and CYP3A4 enzymes. Due to the genetic polymorphisms in CYP2D6 genes, high variation in the clinical outcomes of TAM treatment is observed among(More)
Tadalafil is a clinically approved phosphodiesterase-5 inhibitor for the treatment of erectile dysfunction and pulmonary arterial hypertension. It contains two chiral carbons, and the marketed isomer is the 6R, 12aR isomer with a methyl substituent on the terminal nitrogen of the piperazinedione ring. In this report, tadalafil analogues with an extended(More)
The protein kinase PKCζ is involved in the fine regulation of the NF-κB transcriptional activity and, therefore, represents a potential pharmacological target in inflammatory diseases. We previously developed a selective, allosteric inhibitor (MA130) of PKCζ. Now, we investigated which of the NF-κB-regulated gene expressions are suppressed by MA130 after(More)
In cancer cells, kinases of the Clk family control the supply of full-length, functional mRNAs coding for a variety of proteins essential to cell growth and survival. Thus, inhibition of Clks might become a novel anticancer strategy, leading to a selective depletion of cancer-relevant proteins after turnover. On the basis of a Weinreb amide hit compound, we(More)
