In Vitro | Acetazolamide also inhibits hCA II with an IC50 of 130 nM[1]. Acetazolamide (Ace) is a small heteroaromatic sulfonamide that binds to various carbonic anhydrases with high affinity, acting as a carbonic anhydrase (CA) inhibitor[2]. Compared with the control group, the high Acetazolamide concentration (AceH, 50 nM), Cisplatin (Cis; 1 µg/mL) and Cis combined with the low Acetazolamide concentration (AceL, 10 nM) treatments significantly reduces viability of Hep-2 cells[2]. Treatment with the Acetazolamide/Cis combination significantly increases the expression levels of P53, as both AceL+Cis and AceH+Cis treatments result in significantly increased P53 protein expression levels compared with the control group. The Ace/Cis combination treatment significantly reduces the bcl-2/bax expression ratio, and increases the expression of caspase-3 protein, compared with the control group. AceL, AceH, Cis and AceL+Cis treatments significantly reduce the bcl-2/bax ratio compared with the control group[2]. Combined Ace and Cis treatment effectively promotes apoptosis in Hep-2 cells[2]. Combined treatment with Ace/Cis markedly decreases the expression of AQP1 mRNA in Hep-2 cells. Both AceH and AceL+Cis treatments decrease the expression of aquaporin-1 (AQP1) mRNA in Hep-2 cells compared with the control group[2]. |
In Vivo | Acetazolamide (40 mg/kg) significantly potentiates the inhibitory effect of MS-275 on tumorigenesis in neuroblastoma (NB) SH-SY5Y xenografts[3]. Acetazolamide (40 mg/kg) and/or MS-275 treatment reduce expression of HIF1-α and CAIX in NB SH-SY5Y xenograft[3]. Acetazolamide (40 mg/kg), MS-275 and Acetazolamide+MS-275 reduce expression of mitotic and proliferative markers in NB SH-SY5Y xenografts[3]. |
Cell Assay | Cell Viability Assay[2] Cell line: Hep-2 cells and HUVECs Concentration: 10 nM and 50 nM Incubation time: 48 h Assay: The cell viability of Hep-2 cells and HUVECs is measured by MTT assay. Hep-2 cells and HUVECs in logarithmic growth phase are plated in 96-well plates. Following 48 h of drug treatment as indicated, 200 µL MTT (5 mg/mL) is added to each well. Cells are incubated with the MTT solution at 37°C for 4 h. Then, 150 µL DMSO is added for 5 min. The optical density (OD) values are measured at 490 nm with a Versamax Microplate reader. Note: Combined treatment effectively reduced viability in Hep-2 cells. |
Animal Admin | In vivo studies[3] Animal model: 4-6 weeks-old female NOD/SCID mice Dosage: 40 mg/kg, intraperitoneal injection, every day for 2 weeks Administration: Mice are randomized into four groups (5 mice per group). The control and treatment groups receive intraperitoneal injections of vehicle (PBS) or Acetazolamide (40 mg/kg), MS-275 (20 mg/kg) or the combination, respectively, every day for 2 weeks. Experiments are terminated when tumor sizes exceed 2 cm3 in volume or animals show signs of morbidity. Tumor diameters are measured on a daily basis until termination. Note: Inhibited tumor growth of NB xenografts with significant anti-tumor growth potentiation effect. |
