Aims: The main goal of this work where is to synthesize new original spirocyclic hydroxamic acids, investigate their cytotoxicity against to the panel of tumor cell lines and possible mechanism of action of these active compounds. Background: Hydroxamic acids are one of the promising classes of chemical compounds with proven has anticancer potential properties. This is manifested in the presence of metal chelating and antioxidant activities, the ability to inhibit histone deacetylase enzymes and a chemosensitizing effect against well known cytostatics. Objective: Original spirocyclic hydroxamic acids were synthesized and spectrums of their antiproliferative activities were investigated. Methods: The cytotoxic activities on different tumor lines (SH-SY5Y, HeLa and healthy cells HEK-293) were investigated and determined possible underlying mechanisms of their activity. Result: New original spirocyclic hydroxamic acids were synthesized. These compounds exhibit antiproliferative properties against of the various tumor cultures cells and also exhibits antioxidant activity, a depolarizing effect on the mitochondrial membrane, inhibit the activity of the histone deacetylase enzyme, and also decrease of basal glycolysis and glycolytic capacity reserve of HeLa and SH-SY5Y tumor cell lines. Conclusion: The most promising are compounds 5j-l containing two chlorine atoms as substituents in the quinazoline part of the molecule and hydroxamate function. Therefore, these compounds can be considered as hit compounds for the development on their basis multi-target anticancer agents.

STAT3 is a master transcriptional regulator that plays an important role in the induction of both immune activation and immune tolerance in dendritic cells (DCs). The transcriptional targets of STAT3 in promoting DC activation are becoming increasingly understood; however, the mechanisms underpinning its role in causing DC suppression remain largely unknown. To determine the functional gene targets of STAT3, we compared the genome-wide binding of STAT3 using ChIP sequencing coupled with gene expression microarrays to determine STAT3-dependent gene regulation in DCs after histone deacetylase (HDAC) inhibition. HDAC inhibition boosted the ability of STAT3 to bind to distinct DNA targets and regulate gene expression. Among the top 500 STAT3 binding sites, the frequency of canonical motifs was significantly higher than that of noncanonical motifs. Functional analysis revealed that after treatment with an HDAC inhibitor, the upregulated STAT3 target genes were those that were primarily the negative regulators of proinflammatory cytokines and those in the IL-10 signaling pathway. The downregulated STAT3-dependent targets were those involved in immune effector processes and antigen processing/presentation. The expression and functional relevance of these genes were validated. Specifically, functional studies confirmed that the upregulation of IL-10Ra by STAT3 contributed to the suppressive function of DCs following HDAC inhibition.
