生物活性

LS-Q2 is a highly selective CDK4/9 inhibitor with IC50 values of 1.4 nM and 6.2 nM. LS-Q2 inhibits cancer cells proliferation, induces G2/M phase arrest, apoptosis and reduces pSer2 RNA polymerase II expression. LS-Q2 interacts synergistically with BET and Bcl-2 inhibitors to drive antitumor activity. LS-Q2 can be used for the research of cancer, such as malignant solid tumors[1].

体外研究
(In Vitro)

LS-Q2 (Compound 6m) 对 CDK4CDK9 表现出强效抑制活性,IC50 值分别为 1.4 nM 和 6.2 nM;对 CDK6 的抑制活性较弱 (IC50 = 52 nM),对 CDK1、2、5、7、8 的抑制活性极低 (IC50 >700 nM)[1]
LS-Q2 可抑制 MIA Paca-2、HCT116、Hela 细胞的肿瘤细胞增殖,其 IC50 值分别为 0.62、0.75、2.77 μM[1]
LS-Q2 (0.5-2 μM; 24 h) 可诱导 HepG2 细胞发生 G2/M 期阻滞和细胞凋亡[1]
LS-Q2 (0.5-2 μM; 24 h) 可降低 HepG2 细胞中 pSer2 RNA 聚合酶 II 的表达水平[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
