生物活性 | Mycophenolic acid is a potent uncompetitive inosine monophosphate dehydrogenase (IMPDH) inhibitor with anEC50of 0.24 μM. Mycophenolic acid demonstrates antiviral effects against a wide range of RNA viruses includinginfluenza. Mycophenolic acid is an immunosuppressive agent. Antiangiogenic and antitumor effects[1][2]. |

体外研究 (In Vitro) | Mycophenolic acid demonstrates antiviral effects against a wide range of RNA viruses including influenza, dengue virus, Zika virus, rotavirus, CCHFV, and hantavirus[1]. IMPDH is the rate-limiting enzyme in the de novo synthesis of guanosine nucleotides[2]. Mycophenolic acid (0.01-1 μM; 72 hours) exhibits preferential antiproliferative activity against the endothelial cells and fibroblasts. Endothelial cells are most sensitive cells to Mycophenolic acid treatment with an IC50 <500 nm for antimitotic effects[2]. Fibroblasts are also prone to Mycophenolic acid-induced cell cycle inhibition but exhibit a higher IC50 (<1 μm) compared with endothelial cells. the two human tumor cell lines a549 non-small lung cancer cells and pc3 prostate show intermediate sensitivity an ic50 >1 μM. U87 glioblastoma cells are resistant against MPA treatment up to 1 μM[2]. Mycophenolic acid (0.05-2 μM; 18 hours) exhibits a dose-dependent down-regulation of HDAC2 and MYC, whereas up-regulates NDRG1[2].
Cell Proliferation Assay[2] Cell Line: | Primary isolated human dermal microvascular endothelial cells (HDMVEC) , fibroblasts, U87 glioblastoma cells, PC3 prostate cancer cells, A549 non-small cell lung cancer cells | Concentration: | 0.01, 0.1, 1 μM | Incubation Time: | 72 hours | Result: | Exhibited preferential antiproliferative activity against HDMVEC and fibroblasts. Whereas U87 glioblastoma cells were resistant to treatment, A549 non-small cell lung cancer and PC3 prostate cancer cells showed intermediate sensitivity. |
Western Blot Analysis[2] Cell Line: | HDMVEC | Concentration: | 0, 0.05, 0.1, 0.5, 1, and 2 μM | Incubation Time: | 18 hours | Result: | Showed a dose-dependent regulation of HDAC2, MYC, and NDRG1. |

体内研究 (In Vivo) | Mycophenolic acid exerts its antitumor effects via modulation of the tumor microenvironment, U87 tumor growth is markedly inhibited in vivo in BALB/c nude mice[2].
Animal Model: | Athymic 8-week-old, 20 g BALB/c nu/nu mice bearing Mycophenolic acid-resistant human U87 tumor model[2] | Dosage: | 120 mg/kg MMF (the morpholinoethyl ester prodrug of Mycophenolic acid) | Administration: | Oral gavage; b.i.d. | Result: | MMF (the morpholinoethyl ester prodrug of Mycophenolic acid) significantly inhibited tumor growth (~70% after day 14 after tumor implantation) in MMF-treated versus control mice. Microvessel density (CD31 staining) and pericyte coverage determined by α-smooth muscle actin staining were markedly reduced in MMF-treated versus control tumors (44% and 78%, respectively). |
