BICYCLIC KINASE INHIBITORS AND USES THEREOF

The invention relates to kinase inhibitors, in particular inhibitors of protein kinases including the SIK-family, CSF1R, HCK, TEK-family, BRK, ABL, KIT and/or their mutants. Although structurally similar to other bicyclic kinase inhibitors, the kinase inhibitors of the invention are distinctive; possessing a particular class of heterocyclic moiety. Such kinase inhibitors can display one or more certain properties distinct to their structurally similar kinase inhibitors. The kinase inhibitors of the invention or pharmaceutical compositions comprising them may be used in the treatment of a disorder or condition, such as a proliferative disorder, for example, a leukaemia or solid tumour. In particular, these and other structurally related kinase inhibitors may be used in the treatment of a proliferative disorder - such as a mixed phenotype acute leukaemia (MPAL) - characterised by (inter-alia) the presence of MEF2C protein, a human chromosomal translocation at 11q23, and/or a KMT2A fusion oncoprotein. The kinase inhibitors or pharmaceutical compositions of the invention may be used topically to modulate skin pigmentation in a subject, for example to impart UV protection and reduce skin cancer risk.

Synthesis and characterization of the first inhibitor of: N -acylphosphatidylethanolamine phospholipase D (NAPE-PLD)

N-Acylphosphatidylethanolamine phospholipase D (NAPE-PLD) is a membrane-associated zinc enzyme that catalyzes the hydrolysis of N-acylphosphatidylethanolamines (NAPEs) into fatty acid ethanolamides (FAEs). Here, we describe the identification of the first small-molecule NAPE-PLD inhibitor, the quinazoline sulfonamide derivative 2,4-dioxo-N-[4-(4-pyridyl)phenyl]-1H-quinazoline-6-sulfonamide, ARN19874.

Wnt signal pathway inhibitor and use thereof

The invention relates to heterocyclic compounds with Wnt signal channel inhibition activity, particularly including compounds, pharmaceutically acceptable salts, various isotopes, various isomers or various crystal structures thereof having a structure represented by a general formula I (shown in the specification). By the compounds and a composition of the compounds, a Wnt signal channel can be effectively inhibited and diseases related to the Wnt signal channel can be treated or prevented.

Exploration of the linkage elements of porcupine antagonists led to potent Wnt signaling pathway inhibitors

The Wnt signaling pathway is a pivotal developmental pathway. It operates through control of cellular functions such as proliferation, differentiation, migration and polarity. Aberrant Wnt signaling has been implicated in the formation and metastasis of tumors. Porcupine is a component of the Wnt signaling pathway. It is a member of the membrane-bound O-acyltransferase family of proteins. Porcupine catalyzes the palmitoylation of Wnt proteins, a process which is essential to their secretion and activity. Here we report a novel series of compounds obtained by a scaffold hybridization strategy from two known porcupine inhibitor classes. The leading compound 62 demonstrated subnanomolar (IC50 0.11 nM) inhibition of Wnt signaling in a paracrine cellular reporter gene assay. Compound 62 also potently inhibited Wnt secretion into culture medium, an indication of direct inhibition of the porcupine protein. Furthermore, compound 62 showed excellent chemical, plasma and liver microsomal stabilities. Collectively, these results strongly support further optimization of this novel scaffold to develop better Wnt pathway inhibitors.
