Dissolved in DMSO-Tween-saline; 75 mg/kg; Oral gavage. Female CrTac:NCr-Fox1(nu) athymic mice bearing established SW620 human colorectal tumors
HCT116 colorectal cancer xenograft model: Female nude mice (6-7 weeks old) were subcutaneously injected with 5×10⁶ HCT116 cells (suspended in PBS/Matrigel, 1:1 v/v) into the right flank. When tumors reached 100-150 mm³, mice were randomly divided into two groups (n=8/group): vehicle control (0.5% carboxymethylcellulose + 0.1% Tween 80) and CCT137690 treatment group. CCT137690 was dissolved in the vehicle at 10 mg/mL and administered orally at 50 mg/kg once daily for 14 days. Tumor volume (length × width² / 2) and mouse body weight were measured every 2 days [1] - IMR-32 neuroblastoma xenograft model: Female nude mice were subcutaneously implanted with 1×10⁷ IMR-32 cells (mixed with Matrigel). When tumors reached ~120 mm³, mice were grouped (n=8/group). CCT137690 was prepared in a vehicle of 5% DMSO + 45% PEG400 + 50% normal saline and administered i.p. at 25 mg/kg once daily for 21 days. At study end, tumors were excised and weighed; tumor tissues were fixed in 10% formalin for immunohistochemical analysis of MYCN and phospho-histone H3 [2] |

Oral bioavailability: In male Sprague-Dawley rats, oral administration of CCT137690 (20 mg/kg) resulted in an oral bioavailability of 35%—a key improvement over earlier analogs. Plasma concentration-time profiles showed a Cmax of 1.2 μg/mL at 2 h post-dosing and a terminal half-life (t₁/₂) of 5.8 h [1]
- Intravenous pharmacokinetics (rats): Intravenous injection of CCT137690 (5 mg/kg) in rats showed a clearance (CL) of 12 mL/min/kg, a volume of distribution at steady state (Vss) of 4.5 L/kg, and a t₁/₂ of 5.2 h [1] - Plasma protein binding: CCT137690 had high plasma protein binding in human (96%), rat (95%), and mouse (94%) plasma, determined by equilibrium dialysis (incubation at 37°C for 4 h, drug concentration: 1 μg/mL) [1] - Metabolic stability: In human liver microsomes, CCT137690 had a t₁/₂ of 4.2 h (moderate stability); in rat liver microsomes, t₁/₂ was 4.8 h. LC-MS/MS identified the major metabolite as a dihydroxylated derivative (accounting for 45% of total metabolites) [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute oral toxicity (mice): Single oral administration of CCT137690 at doses up to 200 mg/kg did not cause mortality. Mice showed transient reduced food intake at doses ≥150 mg/kg but recovered within 48 h. No significant changes in body weight were observed at doses ≤100 mg/kg [1]
- Chronic oral toxicity (rats): Male rats treated with CCT137690 (50 mg/kg oral, daily for 28 days) showed mild myelosuppression: white blood cell count decreased by 15% (vs. control), but red blood cell count and platelet count remained normal. Serum levels of ALT, AST (liver function), and BUN, creatinine (kidney function) were within normal ranges [1] - Toxicity in xenograft models: In the IMR-32 neuroblastoma model, CCT137690 (25 mg/kg i.p., daily for 21 days) caused no significant weight loss (<5%) or histopathological changes in liver, kidney, or heart tissues [2] |

CCT137690 is an imidazo[4,5-b]pyridine derivative developed through lead optimization to improve oral bioavailability and Aurora kinase selectivity—addressing limitations of earlier Aurora inhibitors (e.g., poor solubility, off-target kinase activity) [1]
- The mechanism of action in MYCN-amplified neuroblastoma involves dual effects: inhibition of Aurora B (inducing mitotic arrest and apoptosis) and post-transcriptional downregulation of MYCN (a driver oncogene in neuroblastoma), leading to synergistic antitumor activity [2] - Preclinical data support CCT137690 as a candidate for MYCN-amplified neuroblastoma—an aggressive subtype with limited treatment options. It showed no cross-resistance with standard chemotherapeutics (e.g., cisplatin) in IMR-32 cells [2] |
