本発明に用いられる化合物を3次元培地に添加した際の細胞の増殖促進効果を検討した。具体的には、前培養(接着培養)したSKOV3細胞(ヒト卵巣がん由来細胞株)を回収し、3次元細胞培養培地(「FCeM(登録商標)」(日産化学株式会社))に懸濁し、細胞懸濁液を調製した。該細胞懸濁液を384ウェル平底超低接着表面マイクロプレート(コーニング社製、#3827)のウェルに1ウェル当たり1000 cells/40μL/ウェルになるように播種した。プレートに播種された細胞懸濁液を37℃、5%CO2下で一晩静置した。次いで、本発明に用いられる化合物のDMSO希釈溶液を、終濃度5μM(または、5μMおよび10μMの2段階)となるように4.44μLを添加した(添加後撹拌なし)。各化合物の添加後、37℃、5%CO2下で4日間静置培養した。5日目の培養液に対してATP試薬44.4μL(CellTiter-Glo(登録商標)Luminescent Cell Viability Assay, Promega社製)を添加し懸濁させ、15分間室温で静置した。FlexStation3(Molecular Devices社製)にて発光強度(RLU値)を測定し、細胞増殖を評価した。
