, (2022/01/04)
Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.

We previously discovered a series of novel biaryloxazolidinone analogues bearing a hydrazone moiety with potent antibacterial activity. However, the most potent compound OB-104 exhibited undesirable chemical and metabolic instability. Herein, novel biaryloxazolidinone analogues were designed and synthesized to improve the chemical and metabolic stability. Compounds 6a-1, 6a-3, 14a-1, 14a-3 and 14a-7 showed significant antibacterial activity against the tested Gram-positive bacteria as compared to radezolid and linezolid. Further studies indicated that most of them exhibited improved water solubility and chemical stability. Compound 14a-7 had MIC values of 0.125–0.25 μg/mL against all tested Gram-positive bacteria, and showed excellent antibacterial activity against clinical isolates of antibiotic-susceptible and antibiotic-resistant bacteria. Moreover, it was stable in human liver microsome. From a safety viewpoint, it showed non-cytotoxic activity against hepatic cell and exhibited lower inhibitory activity against human MAO-A compared to linezolid. The potent antibacterial activity and all these improved drug-likeness properties and safety profile suggested that compound 14a-7 might be a promising drug candidate for further investigation.

Disclosed is a novel oxazolidinone derivative represented by Formula 1 above, in particular, a novel oxazolidinone compound having a cyclic amidoxime or cyclic amidrazone group. In Formula 1, R and Q are the same as defined in the detailed description. In addition, disclosed is a pharmaceutical composition for an antibiotic which includes the novel oxazolidinone derivative of Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The novel oxazolidinone derivative, the prodrug thereof, the hydrate thereof, the solvate thereof, the isomer thereof, and the pharmaceutically acceptable salt thereof have broad antibacterial spectrum against resistant bacteria, low toxicity and strong antibacterial effects against Gram-positive and Gram-negative bacteria and thus may be effectively used as antibiotics.
