This study has demonstrated that acetylshikonin (ACS), the isolated ingredient from Lithospermum canescens Lehm. roots, in a daily dose of 200 microg for 3 days, inhibited cutaneous angiogenesis induced by L-1 sarcoma cells in Balb/c mice.
Shikonin, a major component of Lithospermum erythrorhizon and Arnebia euchroma, exhibits antiinflammatory, immunomodulatory and antitumour activities. Although many recent studies have focused on the antitumour effects of shikonin, the exact mechanisms underlying its antitumour and immunomodulatory
To search for compounds that disrupt binding of the EWS-FLI1 fusion protein to its cognate targets, we developed a homogeneous high-throughput proximity assay and screened 5200 small molecule compounds. Many well-known DNA-binding chemotherapeutic agents, such as actinomycin D, cisplatin,
2- or 6-(1-hydroxyiminoalkyl)-5,8-dimethoxy-1, 4-naphthoquinone(2- or 6-hyim-DMNQ) derived from the roots of Lithospermum erythrorhizon was synthesized for the evaluation of antitumor activities. Among those derivatives, 2-hyim-DMNQ-S33 was found to be a potent anticancer agent. This compound
