Synthesis, antibacterial activities, mode of action and acute toxicity studies of new oxazolidinone-fluoroquinolone hybrids

To combat bacterial resistance, a series of new oxazolidinone-fluoroquinolone hybrids have been synthesized and characterized. All synthetic hybrids were preliminarily evaluated for their in vitro antibacterial activities against 6 standard strains and 3 clinical isolates. The majority of hybrids displayed excellent activities against Gram-positive bacteria, but limited activities against Gram-negative bacteria. Hybrids OBP-4 and OBP-5 were found to be the most promising compounds. Further, in vitro antibacterial activities, mode of action and acute toxicity in mice of hybrids OBP-4 and OBP-5 were investigated. Hybrids OBP-4 and OBP-5 exhibited potent activities against Gram-positive bacteria, including drug-resistant strains. Correspondingly, studies on the mode of action of hybrids OBP-4 and OBP-5 indicated a strong inhibitory activity on protein synthesis by binding the active site of 50S subunit, but a weak inhibitory action on DNA synthesis. In addition, LD50 values of hybrids OBP-4 and OBP-5 in the acute oral toxicity were larger than 2000 mg/kg, suggesting a good safety profile.

HYDRAZINE COMPOUND AS BLOOD COAGULATION FACTOR Xa INHIBITOR

Provided is a compound of formula (I) or a pharmaceutically acceptable salt thereof, wherein X is selected from a 3-9 membered carbon ring or its phenyl ring, and a 4-10 membered heterocyclic ring or its benzo ring; Y and Z are independently selected from 4-9 membered saturated heterocyclic rings respectively; RI-3 are independently selected from H, F, Cl, Br, I, CN, OH, SH,NH2, CHO, COOH respectively, or selected from C1-10 alkyls or heteroalkyls optionally substituted by R01, C3-10 alkyls ring hydrocarbon groups or heterocyclic hydrocarbon groups, C1-10 alkyls or heteroalkyls substituted by C3-10 ring hydrocarbon groups or heterocyclic hydrocarbon group.
