Description
[Technical Field]
[0001] FIELD OF THE INVENTION The present invention relates to novel heterocyclic compounds that exhibit antibacterial properties. The present invention also relates to methods of using these compounds for the treatment or prevention of bacterial infections and resulting diseases, particularly for the treatment or prevention of infections caused by Acinetobacter baumannii and resulting diseases. [Background technology]
[0002] Background of the Invention Acinetobacter baumannii is a Gram-negative, aerobic, non-fermenting bacterium that has been recognized over the past few decades as an emerging pathogen with severely limited treatment options.
[0003] A. baumannii is considered a serious threat by the U.S. Centers for Disease Control and Prevention and currently causes the majority of hospital-acquired infections. It belongs to the so-called "ESKAPE" pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species, and Escherichia coli) that effectively "escape" the activity of antimicrobial agents.
[0004] A. baumannii occurs most frequently in intensive care units and surgical wards, where widespread antibiotic use has allowed it to select for resistance to all known antimicrobial agents and can cause infections such as bacteremia, pneumonia, meningitis, urinary tract infections, and wound infections.
[0005] A. baumannii has an extraordinary ability to upregulate and acquire resistance determinants and exhibits environmental persistence that allows it to survive and spread in hospital environments, making this organism a frequent cause of infectious disease outbreaks and a local healthcare-associated pathogen.
[0006] Due to increasing antibiotic resistance to most, if not all, available therapeutic options, multidrug-resistant (MDR) A. baumannii infections, especially those caused by carbapenem-resistant A. baumannii, are extremely difficult or even impossible to treat, resulting in increased morbidity and length of stay in intensive care units, as well as high mortality.
[0007] According to the Antimicrobial Availability Task Force (AATF) of the Infectious Diseases Society of America (IDSA), Acinetobacter baumannii has been and remains considered "a prime example of the mismatch that exists between unmet medical need and the current antibiotic research and development pipeline." Thus, there is a high demand and need to identify compounds suitable for the treatment of diseases and infections caused by Acinetobacter baumannii.
[0008] The present invention provides novel compounds that exhibit activity against drug-susceptible and drug-resistant strains of Acinetobacter baumannii. Summary of the Invention

[0102] In the ceremony, P.G. 2 is a protecting group, e.g., BOC, SEM, TBS, or PG 2 H (no protection).
[0103] Intermediate G can be prepared according to Scheme 3.

[0109] In addition to the procedures outlined in Scheme 4, intermediates H-K and M-Q can also be prepared according to Scheme 5. Thus, Suzuki coupling of intermediate A with boronic ester intermediate G in the presence of a palladium catalyst and a phosphine ligand provides compound G. Hydrolysis of compound G provides carboxylic acid intermediate L, which is then coupled with a variety of amines in the presence of a condensing agent such as HATU / DIPEA in a solvent such as DMSO to provide intermediates H-K and M-Q.
[0110] [ka]
[0111] In the ceremony, P.G. 1 is a protecting group such as BOC, or PG 1 is H (unprotected), PG 2 is a protecting group, e.g., BOC, SEM, TBS, or P 2 is H (unprotected).
[0112] Examples can be prepared according to Scheme 6. Thus, intermediates HK and MQ can be converted to PG 2 (PG 2 (if not hydrogen) to give compound H. Subsequent PG 1 Removal of (PG 1 is not hydrogen) to finally obtain the Example. The order of the deprotection steps can also be reversed via Compound I. In some cases, the final Example is achieved by alkylation of a particular intermediate, for example, methylation using MeI in the presence of DIPEA in acetonitrile at room temperature. The protecting group PG 1 and P.G. 2 The removal of can be carried out before or after the alkylation step, depending on the requirements of the substitution pattern.
