Both reverse transcriptase (RT) and integrase (IN) play crucial roles in the life cycle of HIV-1, which are also key targets in the area of anti-HIV drug research. Reverse transcriptase inhibitors are involved in the most employed drugs used to treat AIDS patients and HIV-infected people, while one of the integrase inhibitors has already been approved by US FDA to appear on the market. Great achievement has been made in the research on both, separately. Recently, much more attention of medicinal chemistry researchers has been attracted to the strategies of multi-target drugs. Compounds with excellent potency against both HIV RT and IN, evidently defined as dual inhibitors targeting both enzymes, have been obtained through considerable significant exploration, which can be classified into two categories according to different strategies. Combinatorial chemistry approach together with high throughput screening methods and multi-target-based virtual screening strategy have been useful tools for identifying selective anti-HIV compounds for long times; Rational drug design based on pharmacophore combination has also led to remarkable results. In this paper, latest progress of both categories in the discovery and structural modification will be covered, with a view to contribute to the career of anti-HIV research.

This study was aimed to evaluate the effectiveness of solution form of 17% ethylenediaminetetraacetic acid (EDTA) on removing smear layer of root canals at different exposure time periods and to provide scientific basis for EDTA as a choice of root canal irrigation in clinical practice. Twenty-five single-rooted teeth were randomly divided into 5 groups: control group (group A) was given 2.5% NaOCl, and 4 experimental groups were given 2.5% NaOCl and 17% EDTA, including groups B, C, D and E with exposure time of 1, 3, 5 and 7 min, respectively. After preparation of the root canals, the teeth were split along their longitudinal axis, and the root sections were examined under scanning electron microscope for evaluation of smear layer removal and erosion on the surface of the root canal walls. The specimens in group B showed presence of smear layer on the walls of the root canal with no statistical difference from that in group A (P>0.05). In groups C and D, partial removal of smear layer was obtained, and there was no significant difference between the two groups (P>0.05), but there was significant difference in removal of smear layer between group C and group B (P<0.05). Root canal walls in group E specimens showed almost complete removal of smear layer, and the removal of smear layer was significantly different from that in group D (P<0.01). There was no significant change in the structure of the surface of root canal for each sample. It was concluded that combined irrigation with 17% EDTA and 2.5% NaOCl could remove the smear layer with no significant alteration in dentinal structure when the chelating agent was applied for 7 min. At 3 and 5 min of application, partial removal of smear layer was observed and at 1 min negligible removal of smear layer was achieved.

AIM: To investigate the effect of ginsenoside-Rg3 on the expression of vascular endothelial growth factor (VEGF) and tumor necrosis factor-α (TNF-α) in retina with diabetic rats and its roles in preventing neovascularization in diabetes. METHODS: Sixty male Wistar rats were divided into 3 groups randomly: negative control group, diabetic control group and ginsenoside-Rg3 treatment group (5mg/kg, 0.2mg/mL) followed by establishing diabetic model. The expression of VEGF and TNF-α were measured after 8 weeks. RESULTS: There were significant differences among negative control group, diabetic control group and ginsenoside-Rg3 treatment group in the expression of VEGF and TNF-α (F=129.363, 211.992; all the P<0.01). VEGF and TNF-α expression were significantly higher in diabetic control group and ginsenoside-Rg3 treatment group than that in negative control group (P<0.01), with a significant reduction in ginsenoside-Rg3 treatment group than that in diabetic control group (P<0.01). CONCLUSION: Ginsenoside-Rg3 can down-regulate the expression of VEGF and TNF-α in retina, which may interfere in the development of diabetic retinopathy.
