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 R
1
and R
2
, which may be the same or different, represents a hydrogen atom, an optionally substituted C
1-6
alkyl group, an optionally substituted C
3-10
cycloalkyl group, an optionally substituted C
6-14
aromatic hydrocarbon group, or an optionally substituted saturated or unsaturated heterocyclic group, or R
1
and R
2
may form, together with the nitrogen atom to which they are attached, an optionally substituted nitrogen-containing heterocyclic ring; R
3
represents a C
1-6
alkyl group; and each of R
4
, R
5
, and R
6
, which may be identical to or different from one another, represents a hydrogen atom, a halogen atom, an optionally substituted C
1-6
alkyl group, a C
1-6
alkoxy group, a C
1-6
alkylamino group, an optionally substituted aromatic hydrocarbon group, or an optionally substituted saturated or unsaturated heterocyclic group, or R
5
and R
6
may form a ring together with the phenyl ring to which they are attached) or a salt thereof.
提供一种抗肿瘤剂,其表现出优异的c-Met抑制作用,并通过选择性地影响c-Met特异表达的肿瘤细胞来减轻副作用。本发明提供一种由式(I)表示的酰基硫脲化合物:(其中,R1和R2中的每一个,可以相同也可以不同,表示氢原子,可选取代的C1-6烷基,可选取代的C3-10环烷基,可选取代的C6-14芳香烃基,或可选取代的饱和或不饱和杂环基,或R1和R2可以与它们所附着的氮原子一起形成一个可选取代的含氮杂环环;R3表示C1-6烷基;R4、R5和R6中的每一个,可以相同也可以不同,表示氢原子,卤素原子,可选取代的C1-6烷基,C1-6烷氧基,C1-6烷基氨基,可选取代的芳香烃基,或可选取代的饱和或不饱和杂环基,或R5和R6可以与它们所附着的苯环一起形成一个环)。或其盐。
