The present invention belongs to the technical field of pharmaceutical chemistry, and specifically relates to lysophosphatidic acid receptor antagonists and a preparation method therefor. The compounds of the present invention have high LPAR1 antagonist activity and selectivity, low toxicity, good metabolic stability, promising pharmaceutical development prospects, and may be used for preventing or treating LPAR1-related diseases or illnesses. The IC50 values of some of the compounds may be as low as 300nM or below, even 50nM or below. In addition, the compounds all have good safety, and the CC50 value range may be as high as 200µM or above. Furthermore, the compounds have good metabolic stability in humans, mice and rats, and such excellent inhibitory activity is very promising for their application as LPAR1 inhibitors in the described diseases and illnesses. The preparation method for the compounds is simple, has mild reaction conditions and high product yield, and is suitable for industrial production.
