Olomoucine 是 ATP 竞争性的CDKs 的抑制剂。Olomoucine 是一种嘌呤 (HY-34431) 衍生物,可抑制 CDC2/cyclin B, Cdk2/cyclin a, Cdk2/cyclin E (IC50=7 μM),CDK/p35 激酶 (IC50=3 μM) 和 ERK1/p44 MAPK 激酶的活性 (IC50=25 μM)。Olomoucine 也具有调节细胞周期和抗黑色素肿瘤的能力。
生物活性 | Olomoucine is an ATP competitive inhibitor ofCDKs. Olomoucine is a purine (HY-34431) derivative and inhibits CDC2/cyclin B, Cdk2/cyclin A, Cdk2/cyclin E (bothIC50=7 μM), CDK/p35 kinase (IC50=3 μM) and ERK1/p44 MAP kinase (IC50=25 μM)[1][2]. Olomoucine regulates cell cycle and shows anti-melanin tumor activity[3][4]. |
IC50& Target[1] | cdk2-cyclin A 7 μM (IC50) | cdk2-cyclin E 7 μM (IC50) | cdk5-p35 25 μM (IC50) |

体外研究 (In Vitro) | Olomoucine inhibits CDK2 and CDC2 kinases with IC50of 7 μM (CDC2/cyclin B), 7 μM (CDK2/cyclin A), 7 μM (CDK2/cyclin E), 3 Μm (CDK5/p35), and 25μM (ERK1/p44 MAPK), respectively[1]. Olomoucine (0, 5, 10, 15, and 25 μM) is a competitive inhibitor for ATP and as a non-competitive inhibitor for histone H[1]. Olomoucine (0-1000 μM) inhibits DNA synthesis in interleukin-2-stimulated T lymphocytes (CTLL-2 cells) and triggers a Gl arrest similar to interleukin-2 deprivation[2]. Olomoucine (0-100 μM) inhibits Gl/S transition of non-small cell lung cancer cell line MB65 cells[2]. Olomoucine (0-150 μM) inhibits prophase/metaphase transition of Rdditapes oocytes[2]. Olomoucine inhibits tumor cells survival with IC50s of 32.35 μM (dog melanoma), 42.15 μM (mouse B16 melanoma), 82.30 μM (human melanoma), respectively[3].

体内研究 (In Vivo) | Olomoucine (8 mg/kg; i.v.; once daily; 7 d) induces apoptosis in tumor cells on the 3rd day after treatment without side effects[3]. Cassette dosing was found to overestimate the AUC while underestimating the Cmax compared with single dosing administration[4].

Note: Single agents dosing=50 mg/kg, cassette dosing=16.66 mg/kg.
Animal Model: | Dog with spontaneous melanoma (oral and maxillofacial tumors)[3] | Dosage: | 8 mg/kg | Administration: | Intravenous injection; once daily; for 7 days | Result: | Induced programmed cell death of cancer cells and resulted in rapid eradication of at least 68% of the tumor cells. |
Animal Model: | Female Balb C– mice (6 weeks of age; weight of 20 g (±1.2 g))[4] | Dosage: | 50 mg/kg (single agent) or 16.6 mg/kg combinded with purines (cassette) | Administration: | Intravenous injection (tail vein); samples taken at 0.25, 0.5, 1, 2, 4, 6, and 24 h post-dosing | Result: | Resulted faster plasma concentration decreasing with 50 mg/kg (as single agent) than 16.6 mg/kg (as cassette). |
