Herein we report the first small molecule that disrupts the survivin-Smac interaction taking place in mitochondria. The inhibitor, PZ-6-QN, was identified by initially screening a phenothiazine library using a fluorescence anisotropy assay and then conducting a structure–activity relationship study. Mutagenesis and molecular docking studies suggest that PZ-6-QN binds to survivin similarly to the known Smac peptide, AVPI. The results of the effort also show that PZ-6-QN exhibits good anticancer activity against various cancer cells. Moreover, cell-based mechanistic studies provide evidence for the proposal that PZ-6-QN enters mitochondria to inhibit the survivin-Smac interaction and promotes release of Smac and cytochrome c from mitochondria into the cytosol, a process that induces apoptosis in cancer cells. Overall, the present study suggests that PZ-6-QN can serve as a novel chemical probe for study of processes associated with the mitochondrial survivin-Smac interaction and it will aid the discovery of novel anticancer agents.

The chemoselective oxidation of alcohols containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chemistry. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alcohol oxidation methods.

A series of phenothiazine carboxylic acid derivatives, having 6-amino-pyrimidine-2,4(1H,3H)-dione moiety via a appropriate linker, were synthesized and evaluated for their affinity toward human histamine H1 receptor and Caco-2 cell permeability. Selected compounds were further evaluated for their oral anti-histaminic activity in mice and bioavailability in rats. Finally, promising compounds were examined for their anti-inflammatory potential in mice OVA-induced biphasic cutaneous reaction model. Among the compounds tested, phenothiazineacetic acid compound 27 showed both histamine H1-receptor antagonistic activity and anti-inflammatory activity in vivo model.

A series of phenothiazines demonstrating inhibition of RANTES binding to THP-1 cell membranes has been identified. The lead compound RP23618 (IC50 = 3 μM) was found to inhibit specific binding of 125I-RANTES, but not 125I-MCP-1 to THP-1 cell membranes and furthermore to antagonise RANTES, but not MCP-1-induced chemotaxis of THP-1 cells.
