Reaction of silver nitrate with N,N,N',N'-tetra(diphenylphosphanylmethyl)ethylenediamine (dppeda) in the presence of aminothiocarbamide in CH2Cl2/MeOH afforded an unexpected and low-yield binuclear complex [Ag-2(dppatc)(2)](NO3)(2)center dot 2MeOH (dppatc = N,N-bis( diphenylphosphanylmethyl)aminothiocarbamide) (1). An X-ray analysis revealed that the [Ag-2(dppatc)(2)](2+) dication of 1 contains a centrosymmetric double half-open cage structure in which two Ag centers are bridged by a pair of the heteroscopionate dppatc ligands via four Ag-mu-S and four Ag-P bonds. The in situ-formed dppatc ligand in 1 could be readily generated by one-pot and high-yield reaction of diphenylphosphine with formaldehyde and aminothiocarbamide. Further reaction of AgNO3 with dppatc could produce 1 in a relatively high yield. The results provided an efficient route to the synthesis of dppatc and also an interesting insight into its coordination chemistry. (C) 2011 Elsevier B.V. All rights reserved.

Xin Chen, Duanxiu Li, Hailu Zhang, Yanwen Duan, Yong Huang

Summary: In this study, three phenolic acids were used as coformers to prepare binary SIN-phenolic acid coamorphous systems, which showed better physicochemical stability and slower release compared to crystalline SIN and commercial SIN-HCl. This suggests that phenolic acids may be a new type of coformers in the preparation of coamorphous systems for active pharmaceutical ingredients.

Co-amorphous Systems of Sinomenine with Platensimycin or Sulfasalazine: Physical Stability and Excipient-Adjusted Release Behavior

Xin Chen, Duanxiu Li, Hailu Zhang, Yanwen Duan, Yong Huang

Summary: This study presents a drug-drug co-amorphous strategy against infection-associated rheumatoid arthritis (RA) by preparing and characterizing two co-amorphous systems of sinomenine (SIN) with platensimycin (PTM) or sulfasalazine (SULF). Both systems exhibit satisfactory physical stability but reduced SIN release, which may lead to poor therapeutic effect. A controlled release strategy for SIN is demonstrated by adding a small percentage of polymers and a small-molecule surfactant to improve the dissolution behavior. These drug-drug co-amorphous systems could be a potential strategy for the treatment of infection-associated RA.

Dandan Hu, Xin Chen, Duanxiu Li, Hailu Zhang, Yanwen Duan, Yong Huang

Summary: There is a strong interest in developing co-amorphous drug delivery systems to enhance the solubility of BCS class II and IV drugs. Most reported systems have only resulted in limited improvements in solubility. In this study, a co-amorphous system of tranilast (TRA) and matrine (MAR) was successfully prepared, which showed excellent physical stability and significantly enhanced solubility (over 100-fold) and rapid release behavior in vitro. This study demonstrated the great potential of the co-amorphization approach to improve the dissolution behaviors of BCS class II and IV drugs.

CaCO3/TiO2 hybrid microcapsules with self-cleaning and self-repairing functions for decorative coatings

Xingang Wang, Chao Ma, Fubing Zou, Hai Hu, Jiayu Li, Hongyun Luo

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
