- 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.

- Depsipeptides Featuring a Neutral P1 Are Potent Inhibitors of Kallikrein-Related Peptidase 6 with On-Target Cellular Activity
-
Kallikrein-related peptidase 6 (KLK6) is a secreted serine protease that belongs to the family of tissue kallikreins (KLKs). Many KLKs are investigated as potential biomarkers for cancer as well as therapeutic drug targets for a number of pathologies. KLK6, in particular, has been implicated in neurodegenerative diseases and cancer, but target validation has been hampered by a lack of selective inhibitors. This work introduces a class of depsipeptidic KLK6 inhibitors, discovered via high-throughput screening, which were found to function as substrate mimics that transiently acylate the catalytic serine of KLK6. Detailed structure-activity relationship studies, aided by in silico modeling, uncovered strict structural requirements for potency, stability, and acyl-enzyme complex half-life. An optimized scaffold, DKFZ-251, demonstrated good selectivity for KLK6 compared to other KLKs, and on-target activity in a cellular assay. Moreover, DKFZ-633, an inhibitor-derived activity-based probe, could be used to pull down active endogenous KLK6.

- Mild and highly selective palladium-catalyzed monoarylation of ammonia enabled by the use of bulky biarylphosphine ligands and palladacycle precatalysts
-
A method for the Pd-catalyzed arylation of ammonia with a wide range of aryl and heteroaryl halides, including challenging five-membered heterocyclic substrates, is described. Excellent selectivity for monoarylation of ammonia to primary arylamines was achieved under mild conditions or at rt by the use of bulky biarylphosphine ligands (L6, L7, and L4) as well as their corresponding aminobiphenyl palladacycle precatalysts (3a, 3b, and 3c). As this process requires neither the use of a glovebox nor high pressures of ammonia, it should be widely applicable.

- Synthesis and biological evaluation of new N-substituted-N′-(3,5-di/ 1,3,5-trimethylpyrazole-4-yl)thiourea/urea derivatives
-
Several thiourea and urea derivatives were prepared by the reaction of 4-aminopyrazoles with substituted isothiocyanates or isocyanates. The novel compounds were tested anticonvulsant activity using by pentylenetetrazole- induced seizure (PTZ) and maximal electroshock seizure (MES) tests. Among the tested compounds, thiourea derivatives of 4b were afforded 90 and 100% protection in PTZ and MES tests at 50 mg/kg, respectively. Urea derivatives of 5a and 5b were afforded 82 and 100% protection both at 25 and 50 mg/kg. Also synthesized compounds were screened for antituberculosis activity against Mycobacterium tuberculosis H37Rv at 6.25 μg/mL concentration but they were not found active at these concentration. In addition, some selected compounds were evaluated for in vitro anti-HIV activity and they were all negative.
