Paragraph 0117; 0118; 0121-0127; 0172; 0172, (2020/01/12)
The invention discloses polysubstituted thieno[2,3-b]pyridine derivatives, and a preparation method and an application thereof. The structural formula of the derivatives are represented by formula I shown in the description. A compound for inhibiting a urea transporter is screened by using an erythrocyte model. Experimental results show that the compounds (represented by formula I-1) can inhibit the permeation of a urea transporter UT-B mediated erythrocyte membrane to urea, and the effect of the compounds has a dose-dependent relationship; the compounds represented by the formula I-1 have nocytotoxic effect on MDCK cells within an effective dose range, so the effect of the compounds represented by the formula I-1 on inhibiting cell permeation urea is irrelevant to the cytotoxicity of thecompounds; the inhibition effect of the compounds represented by the formula I-1 on the urea transporter UT-B is gradually enhanced; the inhibiting effect of the compounds represented by the formulaI-1 on the UT-B is reversible; and in-vivo test results show that the compounds represented by the formula I-1 can significantly increase the urination volume of rats, reduce the concentration of ureain rat urine and reduce the osmotic pressure, so that the compounds represented by the formula I-1 generate a urea selective diuresis effect in vivo.
