GSK3179106 是一种具有口服活性的，选择性的RET激酶抑制剂，对人和大鼠 RET 的IC50分别为 0.4 nM 和 0.2 nM。GSK3179106 通过减轻炎症后和应激引起的内脏超敏反应而具有用于肠易激综合征 (IBS) 的潜力。
| 生物活性 | GSK3179106 is an orally active and selectiveRETkinase inhibitor withIC50s of 0.4 nM, 0.2 nM for humanRETand ratRET, respectively. GSK3179106 has the potential for irritable bowel syndrome (IBS) through the attenuation of post-inflammatory and stress-induced visceral hypersensitivity[1]. |
| IC50& Target | IC50: 0.4 nM (human RET), 0.2 nM (rat RET)[1] |
体外研究
(In Vitro) | GSK3179106 (10 nM-100 μM; 8 days for TT cells, 3 days for SK-N-AS and A549 cells) inhibits the proliferation of the RET-dependent TT cell line with a mean IC50value of 25.5 nM however has no effect on the proliferation of the RET-independent SK-NAS and A549 cell lines (mean IC50>10 μM and IC30>17 μM, respectively)[1].
GSK3179106 inhibits RET phosphorylation in SK-N-AS cells and TT cells with mean IC50s of 4.6 nM and 11.1 nM, respectively[1].
Cell Viability Assay[1] | Cell Line: | TT, SK-N-AS and A549 cells | | Concentration: | 10 nM-100 μM | | Incubation Time: | 8 days for TT cells, 3 days for SK-N-AS and A549 cells | | Result: | Inhibited the proliferation of TT cell line with a mean IC50 value of 25.5 nM however had no effect on the proliferation of the SK-NAS and A549 cell lines (mean IC50>10 μM and IC30>17 μM, respectively). |

体内研究
(In Vivo) | GSK3179106 (3 or 10 mg/kg; orally; for 3.5 days BID) reduces the visceromotor response (VMR) in comparison to rats given an acetic acid enema and dosed with vehicle[1].
| Animal Model: | Seventy male Sprague Dawley rats (225-250 g, ~7-8 weeks old); Fifty male Fischer 344 rats (225-250 g, ~10-12 weeks old); Sprague Dawley female rats[1] | | Dosage: | 3 and 10 mg/kg | | Administration: | Oral gavage ; administered BID at 8:00 and 16:00 for 3.5 days | | Result: | Reduced the visceral motor response.
Led to a 34-43% inhibition in VMR to colorectal distension (CRD) at 10 mg/kg. |
