Although no solvent was required for the mechanochem. synthesis of the parent complex [CuI(PPh3)2(iq)] (1; iq = isoquinoline), a minimal amount of assisting solvent (PhCN) was required for the mechanochem. syntheses of the three functionalized isoquinoline complexes. The amino-functionalized isoquinoline complexes were successfully synthesized by heating the ground mixture of three types of starting materials at 鈭?00掳, where the PPh3 ligand melted to promote complex formation by acting as the ligand and the solvent. The emission properties strongly depend on the L ligand: Complexes 2 and 3 showed vibronic emission spectra originating from the 3蟺蟺* excited state localized on the L ligand, whereas complex 4 did not show any emission in the visible region.

To describe treatment patterns in Denmark, Norway and Sweden for patients receiving overactive bladder (OAB) pharmacotherapy. This was a prospective, multinational, registry-based study involving three nationwide prescribed drug registries (sample size 6000 patients per country), performed between 1 Jan. and 30 June 2014. Patients were followed prospectively for 12 mo after first pick-up of index medication. The primary objective was to evaluate the proportion of patients picking up first refill of index medication. Secondary objectives included evaluation of the average number of pick-ups collected during 1 yr and time to discontinuation of index medication. A high proportion of patients in the three Nordic countries picked up a first refill of OAB medication: 64-75% for mirabegron and 84-95% for individual antimuscarinics. Amongst treatment-naive patients, the proportion picking up their first mirabegron refill was 60-64%; for individual antimuscarinics it was 30-63%. Mean number of pick-ups during 1 yr ranged from 3.5-5.0 for mirabegron across the countries and for individual antimuscarinics from 3.8-12.3. Median time to discontinuation for mirabegron ranged from 140 (Denmark) to 207 days (Norway) and, for individual antimuscarinics (solifenacin), from 182 (Denmark) to 355 days (Sweden). At 12 mo, the proportion of patients still on treatment with mirabegron and antimuscarinics was 21% and 38%, resp. Treatment patterns in patients with OAB picking up a mirabegron or antimuscarinic prescription in Denmark, Norway and Sweden indicate that persistence remains a challenge.

Berberine alkaloids belong to the class of isoquinoline alkaloids that have been shown to possess anticancer potential, berberine exhibits inhibitory effects on breast cancer development. However, the exact mechanisms of action for anti-breast carcinoma of the alkaloids, including epiberberine, berberrubine and dihydroberberine are still unclear. MTT assay, colony formation, wound healing and transwell invasion assays detected these alkaloids suppressed proliferation, migration and invasion of breast cancer cells. Hoechst and Annexin V-FITC/PI staining were used to analyze the apoptosis of breast cancer cells. Western blotting investigated the changes noted in the expression levels of the key proteins involved in the Wnt/尾-catenin signaling pathway and epithelial to mesenchymal transition (EMT). The results showed that inhibited the proliferation of breast cancer cells. Berberine alkaloids inhibited the cell cycle at G2/M phase in MCF-7 cells, but in MDA-MB-231 cells berberine alkaloids arrested the cell cycle in G0/G1 and G2/M phases. By decreasing 尾-catenin expression, increasing GSK-3尾 expression and decreasing N-cadherin expression, increasing E-cadherin expression, which proved that epiberberine, berberrubine and dihydroberberine inhibited of metastasis of breast cancer cells through Wnt signaling pathway and reversed EMT except berberine. Furthermore, berberine alkaloids exert their anti-breast cancer effects through the synergistic action of intrinsic and extrinsic pathways of apoptosis. These findings highlight the different effects of different berberine alkaloids on breast cancer cells and confirm that berberine alkaloids may be potentially used in the treatment of breast cancer.
