OTS964
目前情况:
价格xxxx/g 每天用量 50-100 mg 建议联合服用
主要问题: 正作用还待考证,副作用呕吐厉害.
目前策略: 保持观望

摘要
OTS964可以口服,可以注射入人体,其一大特点就是毒性低,采用注射的方式比口服的毒性还可以降低一些
(因为前者包含在一种脂质体中)
从原理上说,OTS964 的靶标是 TOPK (T-lymphokine-activated killer cell-originated protein kinase),这是一种多种人类癌症都会表达的蛋白,其作用被认为是促进肿瘤生长。高表达TOPK与乳腺癌和肺癌患者的预后不良有关。
希望能在2015年开展I期临床试验。

mitosis的意思是有丝分裂。
cytokinesis的意思是胞质分裂,它是指有丝分裂或减数分裂之后发生的细胞质的分裂.在细胞分裂末期时,通常于核分裂之后接着发生的胞质体(cytoplast)的分裂。

Abstract
TOPK (T-lymphokine-activated killer cell-originated protein kinase) is highly and frequently transactivated in various cancer tissues, including lung and triple-negative breast cancers, and plays an indispensable role in the mitosis of cancer cells. We report the development of a potent TOPK inhibitor, OTS964 {(R)-9-(4-(1-(dimethylamino)propan-2-yl)phenyl)-8-hydroxy-6-methylthieno[2,3-c]quinolin-4(5H)-one}, which inhibits TOPK kinase activity with high affinity and selectivity. Similar to the knockdown effect of TOPK small interfering RNAs (siRNAs), this inhibitor causes a cytokinesis defect and the subsequent apoptosis of cancer cells in vitro as well as in xenograft models of human lung cancer. Although administration of the free compound induced hematopoietic adverse reactions (leukocytopenia associated with thrombocytosis), the drug delivered in a liposomal formulation effectively caused complete regression of transplanted tumors without showing any adverse reactions in mice. Our results suggest that the inhibition of TOPK activity may be a viable therapeutic option for the treatment of various human cancers.
一些病友经验:

坚持到胜利
专家建议不加辅料。我加辅料淀粉是因为我的电子秤精度不够(0.01),只好混合淀粉1:4,使重量增大5倍,50mg就称250mg。如果用肠溶胶囊且呕吐可以控制,最好不用辅料。
如果能控制住病情的话,我准备一直采用联药的办法,964剂量最大不超过100mg,直到一期临床结束、推荐剂量出来。
脂质体_百度百科
关于脂质体,我虽不是太懂,但察看最初消息来源,记录如下:
OTS964可以口服,可以注射入人体,其一大特点就是毒性低,采用注射的方式比口服的毒性还可以降低一些
(因为前者包含在一种脂质体中)
推测注射用的OTS964 是有脂质体的,从而毒性更低,但口服也还没有排除使用,如何控制好毒副反应(这里看
到主要是 减白和呕吐) 是可持续用药的关键.
