BTO-1 is a cell-permeable benzothiazolo-N-oxide compound that acts as a Polo-like kinase 1 (Plk1) inhibitor. It targets the ATP-binding pocket of Plk1 and has been shown to inhibit Plk1 kinase activity in cell-free kinase assays with an IC50 of 8.0 μM. BTO-1 treatment in cultured cells leads to mitosis defects consistent with the loss of Plk1 function, such as the appearance of monopolar spindles and the reduction of γ-tubulin at the centrosomes. Additionally, Plk1 inhibition by BTO-1 in HeLa cells results in a blockage of Rho and Rho-GEF recruitment, which is crucial for the assembly of a functional contractile ring.

40647-02-7 Usage

Uses

Used in Pharmaceutical Industry:
BTO-1 is used as a Plk1 inhibitor for targeting the ATP-binding pocket of Plk1, which plays a significant role in cell division and mitosis. By inhibiting Plk1, BTO-1 can potentially be employed in the development of therapeutic strategies for cancer treatment, as abnormal cell division is a hallmark of cancer cells.
Used in Cancer Research:
BTO-1 is used as a research tool for studying the role of Plk1 in cancer cell division and mitosis. Its ability to inhibit Plk1 kinase activity and induce mitosis defects makes it a valuable compound for investigating the molecular mechanisms underlying cancer progression and the potential development of novel cancer therapies.
Used in Drug Development:
BTO-1 is used as a lead compound in the development of new drugs targeting Plk1, which may have applications in various cancer types. Its inhibitory effects on Plk1 activity and its ability to induce mitosis defects make it a promising starting point for the design and synthesis of more potent and selective Plk1 inhibitors.
Used in Cell Biology Research:
BTO-1 is used as a cell biology research tool to study the role of Plk1 in cell division, mitosis, and the assembly of the contractile ring. Its effects on Rho and Rho-GEF recruitment provide insights into the cellular processes that are essential for proper cell division and may help in understanding the underlying mechanisms of various diseases related to cell division abnormalities.

Check Digit Verification of cas no

The CAS Registry Mumber 40647-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,4 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40647-02:
(7*4)+(6*0)+(5*6)+(4*4)+(3*7)+(2*0)+(1*2)=97
97 % 10 = 7
So 40647-02-7 is a valid CAS Registry Number.
