一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

UK 1, an unusual bis-benzoxazole metabolite isolated from Streptomyces sp. 517-02, is an inhibitor of topoisomerase II (Topo II) and hepatitis C viral replication. It is an antifungal and an antibiotic, and displays a wide spectrum of potent anticancer activities against lymphoma, leukemia, and certain solid tumor-derived cell lines with IC50 values as low as 20 nM. However, UK 1 is devoid of antimicrobial activity and is inactive against Pseudomonas aeruginosa and Staphylococcus aureus, a methicillin-resistant strain of S. aureus. Additionally, UK-1 can bind a wide variety of di- and tri-valent metal ions, particularly Mg2+ ions, and form complexes with DNA in the presence of Mg2+ ions. Topo II are ATP-dependent enzymes, which can simultaneously cut both strands of the DNA helix to manage DNA supercoils and tangles.

In vitro: UK 1 strongly blocked the growth of human epitheloid carcinoma HeLa, mouse melanoma B16, mouse leukemia P388 cells with ED50 values of 1.22 μg/ml, 1.17 μg/ml, and 0.11 μg/ml, respectively. UK 1 did not display any growth inhibitory activity against bacteria, fungi and yeasts up to 100 μg/ml [1].

In vivo: Up to now, in vivo study of UK 1 is still in the development stage.
