147776-06-5 Usage
Uses
Used in Pharmaceutical Industry:
L-161,982 is used as an EP4 receptor antagonist for blocking PGE2-induced signal transduction and cell proliferation in HCA-7 colon cancer cells. This application is particularly relevant in the development of targeted therapies for colon cancer and potentially other cancer types where PGE2 plays a role in promoting cell growth and survival.
Additionally, L-161,982 can be used as a research tool to study the role of EP4 receptors in various biological processes, such as inflammation, bone formation, and cancer progression. This can help in the development of new therapeutic strategies and a better understanding of the underlying mechanisms involved in these conditions.
Biological Activity
EP 4 receptor antagonist that is selective over all other members of the prostanoid receptor family (K i values are 0.024, 0.71, 1.90, 5.10, 5.63, 6.74, 19 and 23 μ M for human EP 4 , TP, EP 3 , DP, FP, IP, EP 1 and EP 2 receptors respectively). Suppresses PGE 2 -induced bone formation in rats and prevents the nociceptive response induced by misoprostol in formalin-injected mice.
Biochem/physiol Actions
L-161,982 is a potent EP4 receptor antagonist that is selective over all other members of the prostanoid receptor family (Ki values are 0.024, 0.71, 1.90, 5.10, 5.63, 6.74, 19 and 23 μM for human EP4, TP, EP3, DP, FP, IP, EP1 and EP2 receptors respectively.
Check Digit Verification of cas no
The CAS Registry Mumber 147776-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,7 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 147776-06:
(8*1)+(7*4)+(6*7)+(5*7)+(4*7)+(3*6)+(2*0)+(1*6)=165
165 % 10 = 5
So 147776-06-5 is a valid CAS Registry Number.
