Synthesis and in vitro antibacterial activities of 7-(3-aminopyrrolo[3,4-c]pyrazol-5(2H,4H,6H)-yl)quinolone derivatives
摘要:
A series of novel 7-(3-aminopyrrolo[3,4-c]pyrazol-5(2H,4H,6H)-yl)quinolone derivatives were designed, synthesized and evaluated for in vitro antibacterial activities. Compounds 6g, 7g and 7h with the potencies similar to those of gemifloxacin, moxifloxacin, gatifloxacin and levofloxacin against Gram-positive organisms, worth further investigation.

The present invention relates to novel compounds and methods for the manufacture of inhibitors of deubiquitylating enzymes (DUBs) and/or desumoylating enzymes. In particular, the invention relates to the inhibition of ubiquitin C-terminal hydrolase 7 or ubiquitin specific peptidase 7 (USP7). The invention further relates to the use of DUB or desumoylating inhibitors in the treatment of cancer.
