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 L1 (UCHL1). The invention further relates to the use of DUB inhibitors in the treatment of cancer and other indications. Compounds of the invention include compounds having the formula (I) or a pharmaceutically acceptable salt thereof, wherein R1 to R8 are as defined herein.
The present invention provides compounds of formula I or II: wherein X1, X3, R1, R2, R3, R4 and R5 are as described herein, as well as pharmaceutically acceptable salts thereof. Further the present invention is concerned with the manufacture of the compounds of formula I, pharmaceutical compositions comprising them and their use as medicaments.

describes the development of an improved and scalable method for the manufacture of nemiralisib, a phosphatidylinositol-3-kinase delta inhibitor. Incorporation of three consecutive catalytic reactions, including a palladium-catalyzed C–H functionalization and an iridium-catalyzed borylation, significantly simplified and shortened the synthetic sequence. The revised route was successfully implemented in a pilot
EP300 and its paralog CBP play an important role in post-translational modification as histoneacetyltransferases (HATs). EP300/CBP inhibition has been gaining attention as an anticancer treatment target in recent years. Herein, we describe the identification of a novel, highly selective EP300/CBPinhibitor, compound 11 (DS17701585), by scaffold hopping and structure-based optimization of a high-throughput
