In recent years, the concept of nanoparticles being used as an intelligent drug carrier has gained great attention. In this paper, the formulation of a liposome delivery system loaded with a novel benzothiazole-containing cisplatin derivative (CJM-Pt) was carried out. The particle size distributions were determined using dynamic light scattering, and the prepared liposomes showed a suitable size of around 98 nm. Stability studies showed that the CJM-Pt loaded liposomes were stable at 4 °C for more than four weeks. Investigation of triggered release indicated that the release performance of the prepared liposomes was controllable and the releasing effect was remarkable under low pH (42 °C). To test the suitability of the chosen formulation, CJM-Pt loaded liposomes were investigated against several tumor cell lines: MGC-803, SGC-7901, MCF-7 and MDA-MB-231. Furthermore, the cell cycle arrest was examined. The CJM-Pt loaded liposomes have the potential to be applied in drug delivery systems (DDS) for breast cancer therapy.

The present invention relates to a single-step synthesis method of aryl thiol, and more specifically, to a method of synthesizing aryl thiol in a single-step by making aryl halide react with alkane dithiol in the presence of a transition metal catalyst. According to the present invention, a single-step synthesis method using the transition metal catalyst, the synthesis method which is capable of synthesizing aryl thiol from aryl halide at a high yield, can be provided. Various aryl halides may be applied to the synthesis method. Further, the synthesis method has advantages that an easily usable reagent may be used, operations are simple, and reactions can be performed under mild conditions. In addition, the synthesized aryl thiol may be used in the synthesis of advanced molecules such as diaryl sulfides and benzothiophenes.COPYRIGHT KIPO 2017
Catalytic hydrogenation of sulfur-containing nitrobenzene over Pd/C catalysts: In situ sulfidation of Pd/C for the preparation of PdxSy catalysts

The preparation of supported palladium sulfides catalysts has attracted much attention due to their good sulfur-resistant properties in the hydrogenation of sulfur-containing compounds. In this work, we unambiguously demonstrated that Pd/C catalyst could be in situ sulfided by organic sulfur-containing reactant molecules and the sulfidation was highly dependent on temperature. The in situ sulfidation of Pd/C catalyst was composed of a reaction of Pd with the sulfur derived from the cleavage of C-S bond of sulfur-containing reactant molecules, followed by a transformation to PdxSy at high temperatures (around 120 °C). The sulfided Pd/C catalyst could be used for at least 18 recycles without a significant loss in its activity during the hydrogenation of sulfur-containing nitrobenzene at 180 °C with 3 MPa H2, which could be attributed to the stable presence of Pd4S and Pd16S7.
