Establishment of the method for screening the potential targets and effective components of huatuo reconstruction pill.

Huatuo reconstruction pill (HTRP) is a traditional Chinese medicine prescription that mainly treats for hemiplegia and postoperation of brain stroke. Existing pharmacological studies have previously shown that HTRP could inhibit in vitro thrombosis, delay platelet adhesion, dilate blood vessels, and improve the microcirculation disturbances. In this paper, we chiefly concerned about the potential targets of HTRP and tried to figure out the active components of it.

[Anti-MDR tumor mechanism of CIP-36, a podophyllotoxin derivative].

This study is to investigate the antitumor activity of CIP-36 on multidrug resistant human oral squamous carcinoma cell line (KBV200 cells) in vitro and the possible anticancer mechanisms. MTT assay, Hoechst fluorescein stain, RT-PCR and immunohistochemistry were carried out on KBV200 and KB cells. The growth of many tumor cells was obviously inhibited by CIP-36, especially the multidrug resistant cells KBV200.

Virtual screening for natural product inhibitors of HIV-1 integrase.

Since there is no human homolog of this enzyme, HIV-1 integrase (IN) represents a rational and important target for treating HIV infection and preventing AIDS. The 3D structure of full-length HIV-1 IN, either separately or in complex with its inhibitors, has been lacking. Thus, scarce information about the interactions between the HIV-1 IN and its inhibitors can be referenced.
