The invention disclose a compound of formula (I), wherein, R1 is selected from —H or C1-C6 hydrocarbon group, —NH2, —OH, —O(CH2)nCH3 (n=0, 1 or 2), —N(CH3)2, or —CH2N(CH3)2, R2 is selected from an amino acid
or an hydroxy acid
or —OH (R1, R2 are not —CH3 and —OH at the same time), wherein X, Y are
—H, —CH3, —CH2OH, —CH(OH)CH3, —CH2SH, —CH(CH3)2, —CH2CH(CH3)2, —CH(CH3)CH2CH3, —CH2CH2SCH3, —CH2COOH, —CH2CONH2, —CH2CH2COOH, —CH2CH2CH2CH2NH2, or —CH2CH2CONH2, R3-R5 are H or C1-C6 hydrocarbon group. The compound has a low toxicity, can significantly inhibit the migration and invasion of tumor cells in vitro, and can inhibit tumor metastasis in vivo in mice at low concentration, while showing notable sensitizing effect on cytotoxic anti-tumor drugs such as Paclitaxel etc.
本发明公开了式 (I) 的化合物,其中,R1 选自-H 或 C1-C6 烃基、-NH2、-OH、-O(
CH2)n (n=0, 1 或 2)、-N(
CH3)2 或- N( )2,R2 选自
氨基酸
或羟基酸
或-OH(R1、R2 不能同时为- 和-OH),其中 X、Y 为
-H、- 、- OH、-CH(OH) 、- SH、-CH( )2、- CH( )2、-CH( ) 、- S 、- COOH、- CONH2、- COOH、- NH2或- CONH2,R3-R5为H或C1-C6烃基。该化合物毒性低,在体外能显著抑制肿瘤细胞的迁移和侵袭,在小鼠体内低浓度时能抑制肿瘤转移,同时对
紫杉醇等细胞毒性
抗肿瘤药物有明显的增敏作用。
