Nω-Nitro-L-arginyl-L-leucin, also known as Nω-nitro-L-arginine-L-leucine, is a synthetic dipeptide consisting of L-arginine and L-leucine linked together. The L-arginine residue is modified with a nitro group at the ω position, which is the amino group of the L-arginine. Nω-Nitro-L-arginyl-L-leucin is of interest in scientific research due to its potential effects on nitric oxide (NO) production. Nitric oxide is a signaling molecule that plays a crucial role in various physiological processes, including vasodilation and neurotransmission. The nitro group in Nω-nitro-L-arginine-L-leucine can inhibit nitric oxide synthase (NOS), the enzyme responsible for NO production, by competing with L-arginine, the natural substrate of NOS. This inhibition can be used to study the role of NO in various biological systems and diseases. The compound is also used as a research tool to understand the mechanisms of NO-mediated signaling and to develop potential therapeutic strategies for conditions where NO production is dysregulated.
The CAS Registry Mumber 2418-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,1 and 8 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2418-78: (6*2)+(5*4)+(4*1)+(3*8)+(2*7)+(1*8)=82 82 % 10 = 2 So 2418-78-2 is a valid CAS Registry Number.
