develop new antibacterial agents with non-traditional mechanisms to combat the nonstop emerging resistance to most of the antibiotics used in clinical settings. We identified novel pyrazolidinone derivatives as antibacterial hits in an in-house library screening and synthesized several derivatives in order to improve the potency and increase the polarity of the discovered hit compounds. The oxime derivative

A novel, reformed polysilazane obtained by reacting a polysilazane with a compound selected from ammonia, primary and secondary amines, hydrazine and mono-, di- and tri-substituted hydrazines to cross-link the polysilazane with the compound serving as a cross-linking agent or to link the compound to the polysilazane.
