Flavone inspired discovery of benzylidenebenzofuran-3(2H)-ones (aurones) as potent inhibitors of human protein kinase CK2.

In this work, we describe the design, synthesis and SAR studies of 2-benzylidenebenzofuran-3-ones (aurones), a new family of potent inhibitors of CK2. A series of aurones have been synthesized. These compounds are structurally related to the synthetic flavones and showed nanomolar activities towards CK2. Biochemical tests revealed that 20 newly synthesized compounds inhibited CK2 with IC50 values in the nanomolar range. Further property-based optimization of aurones was performed, yielding a series of CK2 inhibitors with enhanced lipophilic efficiency. The most potent compound 12m (BFO13) has CLipE = 4.94 (CLogP = 3.5; IC50 = 3.6 nM) commensurable with the best known inhibitors of CK2.

The ASAS-OMERACT core domain set for axial spondyloarthritis.

BACKGROUND: The current core outcome set for ankylosing spondylitis (AS) has had only minor adaptations since its development 20 years ago. Considering the significant advances in this field during the preceding decades, an update of this core set is necessary. OBJECTIVE: To update the ASAS-OMERACT core outcome set for AS into the ASAS-OMERACT core outcome set for axial spondyloarthritis (axSpA). METHODS: Following OMERACT and COMET guidelines, an international working group representing key stakeholders (patients, rheumatologists, health professionals, pharmaceutical industry and drug regulatory agency representatives) defined the core domain set for axSpA. The development process consisted of: i) Identifying candidate domains using a systematic literature review and qualitative studies; ii) Selection of the most relevant domains for different stakeholders through a 3-round Delphi survey involving axSpA patients and axSpA experts; iii) Consensus and voting by ASAS; iv) Endorsement by OMERACT. Two scenarios are considered based on the type of therapy investigated in the trial: symptom modifying therapies and disease modifying therapies. RESULTS: The updated core outcome set for axSpA includes 7 mandatory domains for all trials (disease activity, pain, morning stiffness, fatigue, physical function, overall functioning and health, and adverse events including death). There are 3 additional domains (extra-musculoskeletal manifestations, peripheral manifestations and structural damage) that are mandatory for disease modifying therapies and important but optional for symptom modifying therapies. Finally, 3 other domains (spinal mobility, sleep, and work and employment) are defined as important but optional domains for all trials. CONCLUSION: The ASAS-OMERACT core domain set for AS has been updated into the ASAS-OMERACT core domain set for axSpA. The next step is the selection of instruments for each domain.

Two "selection" sub-populations (ris- and ris+), as well as two "temperature" ones (ric113 and ric149) were earlier developed from the control ric sub-population with interrupted vein of the fly wing. All five sub-populations were investigated for hybridization of MGE Dm-412 with drosophila polytene chromosomes in situ. The tree of similarity of MGE Dm-412 hybridization patterns was built by the methods of matrix clusterization. The sub-populations with the most resembling expressions of characters (ris- and ric113, ris+ and ric149) were found to be also most similar in patterns of MGE localization and their changes. Nonrandomness of these changes was shown, the similarity of patterns being demonstrated to be mainly the result of the changes. There is evidence that such effects cannot be accounted for by genetic drift and independent stochastic changes in MGE localization.
