The entire contents of the aforementioned Chinese patent applications are incorporated herein by reference. Technical Field

[0002] The present invention relates to a class of cyclic peptides for use against Acinetobacter baumannii and applications thereof, and specifically to a compound represented by formula (I), its tautomers, stereoisomers, hydrates, solvates, pharmaceutically acceptable salts or prodrugs, and preparation methods thereof, as well as applications thereof in the preparation of drugs for treating or preventing infections and diseases caused by Acinetobacter baumannii. Background Art

[0003] Acinetobacter baumannii (scientific name: Acinetobacter baumannii, commonly known as "AB bacteria"), a Gram-negative bacterium, is a strictly aerobic, non-lactose-fermenting, opportunistic pathogen. It lacks flagella and is not very mobile, but is extremely resilient and widely found in nature. Furthermore, the bacterium has strong adhesion, readily attaching to various medical materials. It is also found on healthy human skin (25%) and pharynx (7%), as well as in conjunctivae, saliva, gastrointestinal tract, and vaginal secretions. It has been identified as an ESKAPE pathogen (Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp., Enterococcus faecalis, Staphylococcus aureus), a group of highly antibiotic-resistant pathogens that cause the majority of nosocomial infections.

[0004] The treatment of Acinetobacter baumannii infections has always been a significant clinical challenge, as the bacterium can easily develop resistance to various disinfectants and antimicrobial agents, posing a significant threat to critically ill patients and those in ICUs. The widespread spread of strains such as CRAB (carbapenem-resistant Acinetobacter baumannii), MDR-AB (multidrug-resistant Acinetobacter baumannii), and XDR-AB (pandrug-resistant Acinetobacter baumannii) has become a nightmare for both physicians and patients. Therefore, the development of drugs to treat infections and diseases caused by Acinetobacter baumannii is urgent.

Resolution of a racemic mixture of a compound can be carried out by any of a number of methods known in the art. An exemplary method includes fractional recrystallization using a chiral resolving acid that is an optically active, salified organic acid. Suitable resolving agents for fractional recrystallization methods are, for example, optically active acids, such as tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid, or various optically active camphorsulfonic acids such as the D and L forms of β-camphorsulfonic acid.

High performance liquid chromatography (HPLC) can also be used to carry out supercritical fluid chromatography (SFC). The selection of specific methods and elution conditions, chromatographic column selection can be selected by those skilled in the art according to the structure of the compound and test results.

The compounds of the present invention may exhibit tautomerism. Tautomeric compounds may exist as two or more interconvertible species. Prototropic tautomers arise from the migration of a covalently bonded hydrogen atom between two atoms. Tautomers generally exist in equilibrium, and attempts to isolate a single tautomer usually produce a mixture whose physical and chemical properties are consistent with a mixture of compounds. The position of equilibrium depends on the chemical properties within the molecule. For example, in many aliphatic aldehydes and ketones such as acetaldehyde, the keto form predominates, while in phenols, the enol form predominates. The present invention encompasses all tautomeric forms of the compounds.

[0404] Antibiotic minimum inhibitory concentration (MIC) testing

[0405] The in vitro antibacterial activity of antibiotics was tested by the minimum inhibitory concentration experiment. The test bacteria was Acinetobacter baumannii (ATCC19606) and the culture medium was sterile cation-adjusted MH II broth (BD, Cat. No. 212322). The test compound was dissolved in cation-adjusted MH II broth medium and prepared into a maximum concentration of 64 μg / mL working solution. The solution was serially diluted two-fold with the culture medium and the diluted culture medium was transferred to a sterile 96-well culture plate with 100 μL per well. A control well without compound was also set up. The culture medium was then used to prepare Acinetobacter baumannii to a final concentration of ~1×106 CFU / mL working solution was added to each well of a 96-well plate, 100 μL per well, and blank wells containing no compound and no bacteria were set up at the same time. After mixing, the 96-well plate was placed in a 37°C incubator and incubated for 16 hours. After the incubation was completed, the 96-well plate was transferred to a microplate reader (Molecular Devices, SpectraMax iD5), the absorbance at OD600 of each well was measured, and the inhibition rate of bacterial growth at different compound concentrations was calculated. The lowest concentration at which the compound inhibited bacteria by ≥80% was the minimum inhibitory concentration of the compound.
