delivers the desired 1,2-diarylated and 1,2-arylalkenylated products with excellent regiocontrol. To demonstrate the synthetic utility of the method, a representative product is prepared on gram scale and then diversified to eight 1,2,3-trifunctionalized building blocks using two-electron and one-electron logic. Using this method, three routes toward bioactive molecules are improved in terms of yield

Compounds and methods for treating or preventing cancer associated with binding to the urokinase receptor are provided. Biological processes affected by the compounds include cell migration, cell growth, cell adhesion, angiogenesis, cancer cell invasion, apoptosis, tumor formation, tumor progression, metastasis, degradation of the extracellular matrix, pericellular proteolysis, activation of plasminogen, changes in the levels of an extracellular protease, and changes in the levels of a VEGF receptor.

Virtual screening targeting the urokinase receptor (uPAR) led to (+/-)-3-(benzo[d][1,3]dioxol-5-yl)-N-(benzo[d][1,3]dioxol-5-ylmethyl)-4-phenylbutan-1-amine 1 (IPR-1) and N-(3,5-dimethylphenyl)-1-(4-isopropylphenyl)-5-(piperidin-4-yl)-1H-pyrazole-4-carboxamide 3 (IPR-69). Synthesis of an analogue of!, namely, 2 (IPR-9), and 3 led to breast MDA-MB-231 invasion, migration and adhesion assays with IC50 near 30 mu M. Both compounds blocked angiogenesis with IC50 of 3 mu M. Compounds 2 and 3 inhibited cell growth with IC50 of 6 and 18 mu M and induced apoptosis. Biochemical assays revealed leadlike properties for 3, but not 2. Compound 3 administered orally reached peak concentration of nearly 40 mu M with a half-life of about 2 h. In NOD-S CID mice inoculated with breast TMD-231 cells in their mammary fat pads, compound 3 showed a 20% reduction in tumor volumes and less extensive metastasis was observed for the treated mice. The suitable pharmacokinetic properties of 3 and the encouraging preliminary results in metastasis make it an ideal starting point for next generation compounds.
