The present invention is related to the development of therapeutics and prophylactics for the treatment and/or prevention of bacterial infections in humans and other mammals. A new class of small molecules is disclosed that inhibits the bacterial trans-translation/ribosome rescue mechanism and thus blocks infection of host cells by bacteria. Also disclosed are methods of using the small molecule inhibitors in the treatment/prevention of bacterial infections.

The present invention belongs to the field of medicine, and specifically discloses an amino alcohol derivative represented by Formula I, a pharmaceutically acceptable salt, solvate, polymorph or prodrug thereof. In addition, the present invention also discloses a pharmaceutical composition comprising the above substances, and a use of the substance in the preparation of a medicament for the prevention and treatment of an immune inflammatory disease, or a disease or condition associated with immunological competence such as multiple sclerosis, ALS, CIDP, systemic lupus erythematosus, rheumatoid arthritis, ulcerative colitis, psoriasis, polymyositis, etc.
