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。不同厂家不同批次半岛bd体育手机客户端 溶解度各有差异,仅做参考。若实验所需浓度过大至半岛bd体育手机客户端 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。 |
PC-766B is a macrolide antibiotic existed in anactinomycete strain SC-4710.
PC-766B was active against Gram-positive bacteria, and some fungi and yeasts, yet inactive against Gram-negative bacteria. PC-766B exhibited potent cytotoxicity against murine tumor cell lines in vitro. The IC50 values against P388 leukemia and B16 melanoma were 0.1 and 0.5 ng/ml, respectively [1]. Intraperitoneal administration of PC-766B (0.25mg/kg/day) showed in vivo antitumor activity against P388 leukemia. PC-766B showed a weak inhibitory activity against Na+, K+-ATPase [1].
