Description of UCPH-101

UCPH-101 is an inhibitor of Excitatory Amino Acid Transporter 1 (EAAT1), with an IC50 value of 0.66μM[1]. UCPH-101 acts as a slow-binding, non-competitive EAAT1 inhibitor; it blocks the translocation step within the transport cycle rather than other partial reactions[2]. UCPH-101 is capable of blocking the neuroprotective effects of dexmedetomidine and guanfacine[3]. UCPH-101 induces glioblastoma cell death by promoting the intracellular accumulation of glutamate and has been shown to significantly improve survival in mouse models of glioma[4].

In vitro, treatment of murine MA9-1 cells and human U937 cells with UCPH-101 (20μM) for 6-24 hours significantly increased apoptotic levels in both cell lines, resulting in a decrease in cells in the G1 phase and a corresponding increase in cells in the S and G2/M phases[5]. Treatment of GL261-NS cells, GBM-NS cells, and astrocytes with UCPH-101 (10μM) significantly elevated apoptotic levels in the GL261-NS and GBM-NS cells, while having no effect on the apoptotic levels of the astrocytes[6].

In vivo, intracranial administration of UCPH-101 (10nmol/μL) to mice bearing glioma xenografts significantly improved survival rates. Furthermore, the treatment significantly disrupted the tissue architecture of the brain gliomas, significantly downregulated the expression levels of the glutamate-aspartate transporter (GLAST) within the tumor tissue, and significantly upregulated the expression levels of cleaved Caspase-3[6].

Protocol of UCPH-101

Cell experiment [1]:

Cell lines

Mouse MA9-1 and human U937 cell line

Preparation Method

Mouse MA9-1 cells and human U937 cells were cultured separately and subsequently treated with UCPH-101 at a final concentration of 20µM. After 24h of treatment, the cells were harvested, and apoptosis was detected via flow cytometry using Annexin V-FITC/PI double staining; a treatment group with 250µM TFB-TBOA was included as a control. An additional group of cells was treated with 20µM UCPH-101 for 6h, followed by fixation and PI staining, to analyze cell cycle distribution via flow cytometry.

Reaction Conditions

20µM; 6, 24h

Applications

Following treatment with 20µM UCPH-101 for 24h, apoptosis increased in both murine MA9-1 cells and human U937 cells; conversely, treatment with 250µM TFB-TBOA did not affect cell viability. Cell cycle analysis revealed that UCPH-101 resulted in a decrease in cells in the G1 phase, accompanied by a corresponding increase in cells in the S and G2/M phases.
Animal experiment [2]:

Animal models

Female C57BL/6 N mice、CD1 nude mice

Preparation Method

Five weeks-old female C57BL/6 N (n=10/group for survival studies) and CD1 nude (nude CD1 (HO): CD1-Foxn1nu) mice (n=7/group for survival studies) were intracranially injected with 1×105 GL261-NS or GSCs respectively, in 2μL PBS 1×. The coordinates, with respect to the bregma, were 0.7mm post, 3mm left lateral, 3.5mm deep, and within the nucleus caudatum. Five weeks-old female CD1 nude mice (n=7/group for survival, n=3/group for histolog ical studies); were intracranially injected with 1×105 scram bled or shGLAST GSCs. Five weeks-old female C57BL/6 N mice (n = 7/group for survival analysis; n=4 for histological studies) were injected with 1×105 GL261-NS and treated with 10nmol/μL of UCPH-101 or DMSO as the negative control, 9 days after tumor implantation. For survival studies mice were monitored every day and when suf fering euthanized; for histological studies mice brains were collected and fixed in 4% paraformaldehyde.

Dosage form

10nmol/μL; intracranially injected

Applications

In glioma-bearing mice, a single intratumoral injection of UCPH-101 significantly increased survival by decreasing GLAST expression and inducing apoptosis.
