Piclidenoson (IB-MECA) 是一种首创的,具有口服活性的,选择性的腺苷 A3 受体 (A3AR) 激动剂。Piclidenoson 在不同类型的癌细胞如黑色素瘤、白血病中表现出抗增殖和诱导凋亡 (apoptosis) 的作用。Piclidenoson 可用于自身免疫性炎症疾病和 COVID-19 的研究。
生物活性 | Piclidenoson (IB-MECA) is a first-in-class, orally active and selectiveA3adenosine receptor(A3AR)agonist. Piclidenoson exhibits antiproliferative effect and inducesapoptosisin differentcancercell types like melanoma, leukemia. Piclidenoson can be used for the research of autoimmune inflammatory diseases and COVID-19[1][2][3][4]. |

体外研究 (In Vitro) | Piclidenoson is able to inhibit Forskolin (HY-15371)-stimulated cAMP levels with EC50s of 0.82 μM and 1.2 μM in OVCAR-3 cells and Caov-4 cells, respectively[2]. Piclidenoson (0.0001-100 μM; 48 hours) significantly reduces cell viability in a dose-dependent manner in human ovarian cancer cell lines, with IC50s of 32.14 μM and 45.37 μM for OVCAR-3 and Caov-4 cells, respectively[2]. Piclidenoson (0.001-100 μM; 48 hours) induces apoptosis in ovarian cancer cell line through the caspase pathway[2]. Piclidenoson induces apoptosis via the mitochondrial signaling pathway[2].
Cell Proliferation Assay[2] Cell Line: | OVCAR-3 cells, Caov-4 cells | Concentration: | 0.0001-100 μM | Incubation Time: | 48 hours | Result: | Resulted in a dose-dependent reduction in the cell viability. |
Apoptosis Analysis[2] Cell Line: | OVCAR-3 cells, Caov-4 cells | Concentration: | 0.1 μM, 1 μM, 10 μM, 50 μM, 100 μM | Incubation Time: | 48 hours | Result: | Significant increased in the percentage of apoptosis in a concentration-dependent manner. |
Western Blot Analysis[2] Cell Line: | OVCAR-3 cells, Caov-4 cells | Concentration: | 1 μM, 10 μM, 100 μM | Incubation Time: | 48 hours | Result: | Decreased the expression of Bcl-2 was noticeably and increased the expression of Bax protein. |
