To provide an antitumor agent which exhibits excellent c-Met inhibitory effect and mitigates side effects by virtue of selectively affecting to tumor cells in which c-Met is specifically expressed.
The invention provides an acylthiourea compound represented by formula (I):
(wherein each of R1 and R2, which may be the same or different, represents a hydrogen atom, an optionally substituted C1-6 alkyl group, an optionally substituted C3-10 cycloalkyl group, an optionally substituted C6-14 aromatic hydrocarbon group, or an optionally substituted saturated or unsaturated heterocyclic group, or R1 and R2 may form, together with the nitrogen atom to which they are attached, an optionally substituted nitrogen-containing heterocyclic ring; R3 represents a C1-6 alkyl group; and each of R4, R5, and R6, which may be identical to or different from one another, represents a hydrogen atom, a halogen atom, an optionally substituted C1-6 alkyl group, a C1-6 alkoxy group, a C1-6 alkylamino group, an optionally substituted aromatic hydrocarbon group, or an optionally substituted saturated or unsaturated heterocyclic group, or R5 and R6 may form a ring together with the phenyl ring to which they are attached) or a salt thereof.
提供一种抗肿瘤药,该抗肿瘤药对特异性表达 c-Met 的肿瘤细胞具有选择性影响,从而显示出卓越的 c-Met 抑制作用并减轻副作用。
本发明提供了一种由式(I)代表的酰基硫脲化合物:
(其中 R1 和 R2(可以相同或不同)各自代表氢原子、任选取代的 C1-6 烷基、任选取代的 C3-10 环烷基、任选取代的 C6-14 芳烃基团或任选取代的饱和或不饱和杂环基团,或 R1 和 R2 可与所连接的氮原子一起形成任选取代的含氮杂环;R3代表C1-6烷基;R4、R5和R6(它们可以彼此相同或不同)分别代表氢原子、卤素原子、任选取代的C1-6烷基、C1-6烷氧基、C1-6烷氨基、任选取代的芳香烃基团或任选取代的饱和或不饱和杂环基团,或R5和R6可与它们所连接的苯基环一起形成环)或其盐。
