DRAinh-A250
DRAinh-A250 is an orally active inhibitor of mouse and human SLC26A3 (DRA). DRAinh-A250 inhibits SLC26A3-mediated anion transport, blocks colonic fluid absorption, reduces luminal fluid alkalization in the distal colonic loops of mice, and alleviates Loperamide (HY-156131)-induced constipation in wild-type and cystic fibrosis mice. DRAinh-A250 can be used in the research of constipation and cystic fibrosis-related constipation.

DRAinh-A250 (compound 4ba) (0.001-1 μM) potently inhibits slc26a3-mediated chloride/iodide exchange in Fischer rat thyroid cells expressing mouse slc26a3 and halide-sensitive yellow fluorescent protein, with an IC50 of 0.15 μM[1].
DRAinh-A250 (0.02-12.5 μM) potently inhibits mouse slc26a3-mediated Cl−/HCO3− exchange in FRT cells, with an IC50 of approximately 0.1 μM[2].
DRAinh-A250 (0.01-3 μM) inhibits Cl−/SCN− exchange mediated by mouse slc26a3 in FRT cells, with an IC50 of approximately 0.3 μM[2].
DRAinh-A250 (1 μM; 0-5 min for inhibition kinetics, 10 min for reversibility washout) rapidly inhibits mouse slc26a3-mediated Cl−/I− exchange in FRT-YFP-slc26a3 cells[2].
DRAinh-A250 (0.156-1.25 μM) potently inhibits human SLC26A3-mediated Cl−/I− exchange in HEK cells, with an IC50 of approximately 0.25 μM[2].
DRAinh-A250 (10 μM; 24 h) shows no cytotoxicity to T84 cells after 24-hour incubation[2].

-
Animal Model:wild-type; cystic fibrosis mice with loss of functional CFTR[2]
-
Dosage:5 mg/kg
-
Administration:p.o.; single dose
-
Result:Partially prevented Loperamide-induced reductions in stool weight, pellet number, and stool water content in wild-type mice.
Significantly increased stool weight, pellet number, and stool water content compared to Loperamide-only treated cystic fibrosis mice, reducing Loperamide-induced constipation.
Demonstrated fully reversible anticonstipation effect, with Loperamide-induced constipation remaining intact when administered 24 hours after treatment.
