Compounds of formula (I) are PLK inhibitors, useful for the treatment of cell proliferative diseases wherein R1 is hydrogen, or an optionally substituted (C1-C6)alkyl, (C2-C6)alkenyl, (C2-C6)alkynyl or (C3-C6)cycloalkyl group; R2 is hydrogen, or an optionally substituted (C1-C6)alkyl, (C2-C6)alkenyl, (C2-C6)alkynyl or (C3-C6)cycloalkyl group; R3 is hydrogen, -CN, hydroxyl, halogen, optionally substituted (C1C6)alkyl, (C2-C6)alkenyl, (C2-C6)alkynyl or (C3-C6)cycloalkyl, -NR6R7 or C1-C4 alkoxy, wherein R6 and R7 are independently hydrogen or optionally substituted (C1C6)alkyl; ring A is an optionally substituted mono- or bi-cyclic carbocyclic or heterocyclic ring or a ring system having up to 12 ring atoms; T is a radical of formula (II) wherein R4 is a carboxylic acid group (-COOH), or an ester group which is hydrolysable by one or more intracellular esterase enzymes to a carboxylic acid group; R5 and R15 independently represent the side chain of a natural or non-natural alpha amino acid but neither of R5 and R15 is hydrogen, or R5 and R15 taken together with the carbon atom to which they are attached form a C3-C7 cycloalkyl ring; and Y, L1 and X1 are as defined in the claims.
式(I)的化合物是PLK抑制剂,用于治疗细胞增殖性疾病,其中R1是氢,或者是一个可选择取代的(C1-C6)烷基,(C2-C6)烯基,(C2-C6)炔基或(C3-C6)环烷基;R2是氢,或者是一个可选择取代的(C1-C6)烷基,(C2-C6)烯基,(C2-C6)炔基或(C3-C6)环烷基;R3是氢,-CN,羟基,卤素,可选择取代的(C1C6)烷基,(C2-C6)烯基,(C2-C6)炔基或(C3-C6)环烷基,-NR6R7或C1-C4烷氧基,其中R6和R7分别独立地是氢或可选择取代的(C1C6)烷基;环A是一个可选择取代的单环或双环碳环或杂环,或者是一个具有最多12个环原子的环系统;T是式(II)中的基团,其中R4是一个羧酸基(-COOH),或者是一个可被一个或多个胞内酯酶水解为羧酸基的酯基;R5和R15独立地代表天然或非天然α-氨基酸的侧链,但R5和R15中的任何一个都不是氢,或者R5和R15与它们连接的碳原子一起形成一个C3-C7环烷基环;Y,L1和X1如权利要求中所定义。
