GBT1118 is a potent and orally active allosteric modifier of hemoglobin oxygen affinity. GBT1118 increases tolerance to severe poxia[1].
GBT1118 通过亚胺中间体与血红蛋白 α 链的 N 端缬氨酸共价和可逆地结合,变构地增加细胞内血红蛋白对 O2[1] 的亲和力[1]。
GBT1118 (样本血红蛋白浓度的 25%) 可保护红细胞在严重缺氧期间免受损伤[2]。
GBT1118 (70 or 140 mg/kg; oral; once) 增加小鼠对严重缺氧的耐受性[1]。
Blood and plasma pharmacokinetic parameters of GBT1118 in male mice following 10 mg/kg IV Administration of GBT1118[1]
Matrix | T1/2 (h) | AUC0-∞ (μg⋅h/mL) | Vss (L/kg) | CLs (mL/min/kg) | Blood/Plasma Ratio |
Blood | 13.9 | 2929 | 0.07 | 0.06 | 51.4 |
Plasma | 11.3 | 60 | 2.95 | 3.21 |
Blood and plasma pharmacokinetic parameters of GBT1118 in male mice following 100 mg/kg PO Administration of GBT1118[1]
Matrix | Tmax (h) | Cmax (μg/mL) | AUC0-∞ (μg•h/mL) | F (%) | Blood/Plasma Ratio |
Blood | 2 | 318 | 13428 | 45.8 | 34.1 |
Plasma | 8 | 12 | 224 | 33.5 |
Animal Model: | C57Bl/6 mice, acute poxia model[1] |
Dosage: | 70 or 140 mg/kg |
Administration: | Oral, single dose |
Result: | Improved tolerance to 5% O2 poxia exposure. Increased O2 delivery during poxia, thus preserving MAP, HR, blood flow, and aerobic metabolism. Increased blood O2 loading in the lungs and allowed for increased O2 delivery during poxia. Decreased poxia in vital tissues and lowered lactate levels. |
Animal Model: | C57Bl/6 mice[1] |
Dosage: | 10 or 100 mg/kg |
Administration: | IV or PO (Pharmacokinetic Analysis) |
Result: | Showed good pharmacokinetic parameters. |

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
