The present invention relates to novel compounds and methods for the manufacture of inhibitors of deubiquitylating enzymes (DUBs). In particular, the invention relates to the inhibition of ubiquitin C-terminal hydrolase 30 or ubiquitin specific peptidase 30 (USP30). The novel compounds have formula (I): (Formula (I)) or are pharmaceutically acceptable salts thereof, wherein: R1a, R1b, R1c, R1d, R1e and R1f each independently represent hydrogen, optionally substituted C1-C6 alkyl or optionally substituted C3-C4 cycloalkyl, or R1b and R1c together form an optionally substituted C3-C6 cycloalkyl ring, or R1d and R1e together form an optionally substituted C3-C6 cycloalkyl ring; R2 represents hydrogen or optionally substituted C1-C6 alkyl; A represents an optionally further substituted 5 to 10 membered monocyclic or bicyclic heteroaryl, heterocyclyl or aryl ring; L represents a covalent bond or linker; B represents an optionally substituted 3 to 10 membered monocyclic or bicyclic heterocyclyl, heteroaryl, cycloalkyl or aryl ring; and when -A-L-B is at position x attachment to A is via a carbon ring atom of A, and either: A cannot be triazolopyridazinyl, triazolopyridinyl, imidazotriazinyl, imidazopyrazinyl or pyrrolopyrimidinyl; or B cannot be substituted with phenoxyl; or B cannot be cyclopentyl when L is an oxygen atom.
本发明涉及新型化合物和制造去泛素化酶(DUB)抑制剂的方法。特别是,本发明涉及对泛素 C 端水解酶 30 或泛素特异性肽酶 30(USP30)的抑制。新型化合物具有式(I):式(I))或其药学上可接受的盐,其中:R1a、R1b、R1c、R1d、R1e 和 R1f 各自独立地代表氢、任选取代的 C1-C6 烷基或任选取代的 C3-C4 环烷基,或 R1b 和 R1c 一起形成任选取代的 C3-C6 环烷基环,或 R1d 和 R1e 一起形成任选取代的 C3-C6 环烷基环;R2 代表氢或任选取代的 C1-C6 烷基;A 代表任选被进一步取代的 5 至 10 个成员的单环或双环杂芳基、杂环烷基或芳基环;L 代表共价键或连接体;B 代表任选被取代的 3 至 10 个成员的单环或双环杂环烷基、杂芳基、环烷基或芳基环;当 -A-L-B 位于 x 位时,通过 A 的碳环原子与 A 连接,且任选其一:A 不能是三唑哒嗪基、三唑吡啶基、咪唑三嗪基、咪唑吡嗪基或吡咯嘧啶基;或 B 不能被苯氧基取代;或当 L 为氧原子时,B 不能是环戊基。
