Paragraph 0166-0169; 0190-0192, (2021/08/19)
The invention discloses a preparation method and medical application of benzisothiazole and benzothiophene, and telates to the field of pharmaceutical chemistry. According to the invention, benzisothiazole and benzothiophene are the first type of HIF-2 agonists; compared with a compound M1001 found by the applicant in the earlier stage, the invention has better HIF-2 agonist activity, and has remarkable enhancement activity on expression of mRNA and protein of EPO, VGEF, Glut1, NDRG1 and the like at the downstream of HIF-2, so that the invention can be used for preparing drugs for treating and/or preventing chronic kidney diseases/chronic renal anemia, dyslipidemia and high cholesterol caused by abnormal expression of HIF-2; and the method has a good industrialization prospect.
