TKL002

Revisión del cliente

Based on 1 Customer Validation

TKL002 is a blood-brain barrier-permeable inhibitor of the CTH/H₂S/NF-κB/EMT signaling axis. TKL002 induces G₂/M phase cell cycle arrest and apoptosis in glioblastoma cells. TKL002 inhibits the migration and invasion of glioblastoma cells by upregulating E-cadherin and downregulating N-cadherin and vimentin. TKL002 is applicable to relevant research on glioblastoma.

LNCaP	IC₅₀	1.62 μM Compound: 7d	Cytotoxicity against human LNCaP cells assessed as inhibition of cell viability incubated for 48 hrs by MTT assay Cytotoxicity against human LNCaP cells assessed as inhibition of cell viability incubated for 48 hrs by MTT assay	[PMID: 39908792]

In Vitro

TKL002 (0.625-10 μmol/L; 24-72 h) potently inhibits the proliferation of U87MG, U118MG, and U251MG glioblastoma cells in a dose- and time-dependent manner with selectivity over normal LX2 cells, exhibiting IC₅₀ values ranging from 4.141 to 6.506 μmol/L across cell lines and time points^[1].
TKL002 (6 μmol/L; 48 h) induces late apoptosis in U87MG glioblastoma cells, mediated via upregulation of Bax and caspase-3 and downregulation of Bcl-2 and active-caspase-3^[1].
TKL002 (2-6 μmol/L; 24 h) induces G₂/M phase cell cycle arrest in U87MG and U118MG glioblastoma cells in a concentration-dependent manner, with maximum G₂/M fractions of 22.68% and 30.31% at 6 μmol/L respectively^[1].
TKL002 (2-6 μmol/L; 48 h) reduces CTH, cysteine, and H₂S levels, increases GSH levels, and inhibits NF-κB signaling and pro-inflammatory cytokine expression in U87MG and U118MG glioblastoma cells in vitro in a dose-dependent manner^[1].
TKL002 (2-6 μmol/L; 48 h) inhibits migration and invasion of U87MG and U118MG glioblastoma cells in a dose-dependent manner, mediated via upregulation of E-cadherin and downregulation of N-cadherin and vimentin to suppress epithelial-mesenchymal transition^[1].

In Vivo

TKL002 (5-20 mg/kg; i.p.; once every other day, 7 total administrations) inhibits the growth of subcutaneous glioblastoma xenografts in a dose-dependent manner^[1].
TKL002 (10-20 mg/kg; i.v., once every three days for a total of 5 administrations) can cross the blood-brain barrier, inhibit the growth of orthotopic glioblastoma in a dose-dependent manner, reduce tumor burden, maintain the physical condition of mice, and cause no obvious organ toxicity^[1].

Animal Model:

BALB/c nude (male, 4−5 weeks old, 16−18 g, subcutaneous xenograft model)^[1]
Dosage:

5 mg/kg; 20 mg/kg
Administration:

i.p.; every other day; 7 total doses
Result:

Reduced mean subcutaneous tumor weight to 1.117 g (5 mg/kg) and 0.530 g, compared to 1.458 g in vehicle control.
Achieved similar tumor weight and volume reduction as 5 mg/kg temozolomide at 20 mg/kg.
Showed dose-dependent reductions in splenic index.
Caused minimal pathological changes in liver, spleen, and kidney; no significant changes in heart, liver, lung, or kidney indices.

Animal Model:

BALB/c nude (male, 4−5 weeks old, 16−18 g, orthotopic xenograft model)^[1]
Dosage:

10 mg/kg; 20 mg/kg
Administration:

i.v. via tail vein; every 3 days; 5 total doses
Result:

Reduced in vivo bioluminescent signal intensity to 13.62×10⁴ photons/s (10 mg/kg) and 8.52×10⁴ photons/s (20 mg/kg) on days 15 and 20, versus 25.21×10⁴ photons/s in vehicle control.
Reduced ex vivo tumor bioluminescent signal intensity to 21.48×10⁴ photons/s (10 mg/kg) and 9.20×10⁴ photons/s (20 mg/kg), versus 63.88×10⁴ photons/s in controls.
Maintained normal body condition in 20 mg/kg group, while control mice exhibited weight loss, reduced activity, and cachexia.
Showed marked, dose-dependent reductions in CTH-positive tumor area, with the 20 mg/kg group showing the most pronounced decrease.
Showed a higher survival rate in the 20 mg/kg group, though the difference was not statistically significant.
Caused no significant differences in organ indices among groups.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
