7-Amino-4-methylcoumarin-3-acetic acid (7-Amino-4-methylcoumarin) 是荧光蛋白质标记剂，能够被紫外光(350 nm) 激活，可在蓝色区域 (440-460 nm) 发光。

HSV-1/HSV-2-IN-3 是一种抑制单纯疱疹病毒（HSV）解旋酶-引物酶复合物的化合物，能够阻止病毒基因组复制过程中所需的 DNA 解旋和引物合成步骤。在含有 2% FBS 的 gD 免疫荧光细胞分析中，HSV-2 的 EC50 为 7.0 nM，而在含有 10% 人血清的条件下，其 EC50 为 57.5 nM。在 qPCR 复制分析中，它的 EC50 为 1.1 nM。HSV-1/HSV-2-IN-3 对人类碳酸酐酶表现出高度选择性，其脱靶作用 IC50 为 hCA II 约 2.9 µM，hCA I 大于 35 µM。该化合物可用于抗 HSV 研究。

TAS-103 is a dual inhibitor of DNA topoisomerase I/II, used for cancer research. TAS-103 is a dual inhibitor of DNA topoisomerase I/II. TAS-103 (0.1-10 μM) is active on CCRF-CEM cells, with an IC50 value of 5 nM. TAS-103 (0.1 μM) significantly increases levels of topo IIα FITC immunofluorescence in individual CCRF-CEM cells[1]. TAS-103 (0.01-1 μM) is highly cytotoxic to Lewis lung carcinoma (LLC) cells, and Liposomal TAS-103 is almost as active as free TAS-103[2]. TAS-103 inhibits the viability of HeLa cells, with an IC50 of 40 nM. TAS-103 (10 μM) disrupts signal recognition particle (SRP) complex formation, and induces destabilization of SRP14 and SRP19 and its eventual degradation[3]. TAS-103 (30 mg/kg, i.v.) causes significant tumor growth suppression in mice bearing Lewis lung carcinoma (LLC) cells, without obvious body weight loss, and the liposomal TAS-103 is more active than free TAS-103[2].
