α-Methyl-N-(p-tolylsulfonylmethyl)-urethan, also known as MTSU, is a chemical compound with the molecular formula C10H14N2O3S. It is a potent and selective inhibitor of serine proteases, a class of enzymes that play a crucial role in various biological processes, including blood clotting, digestion, and immune response. MTSU is particularly effective in inhibiting trypsin and chymotrypsin, two well-known serine proteases. Its structure features a urethane group attached to a methyl group and a p-tolylsulfonyl group, which contributes to its inhibitory activity. MTSU is often used in biochemical research to study the function and regulation of serine proteases, and it has potential applications in the development of therapeutics for conditions related to dysregulated protease activity.
The CAS Registry Mumber 3696-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,9 and 6 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3696-58: (6*3)+(5*6)+(4*9)+(3*6)+(2*5)+(1*8)=120 120 % 10 = 0 So 3696-58-0 is a valid CAS Registry Number.
