5087-06-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5087-06-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,8 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5087-06:
(6*5)+(5*0)+(4*8)+(3*7)+(2*0)+(1*6)=89
89 % 10 = 9
So 5087-06-9 is a valid CAS Registry Number.

Activation of sulfonate ester based matrix metalloproteinase proinhibitors by hydrogen peroxide

Daniel, Kevin B.,Major Jourden, Jody L.,Negoescu, Kimberly E.,Cohen, Seth M.

experimental part, p. 313 - 323 (2012/01/13)

This study details the development of matrix metalloproteinase inhibitor prodrugs (proMMPi) that are activated in the presence of reactive-oxygen species (ROS). Conventional matrix metalloproteinase inhibitors (MMPi) utilize a zinc-binding group (ZBG) that chelates to the catalytic zinc(II) ion of matrix metalloproteinases (MMPs) to inhibit their activity. To create ROS-sensitive prodrugs, sulfonate esters were used as a protecting group for the ZBG to block their metal binding ability. Surprisingly, these sulfonate esters were found to be cleaved by H2O2 only when the ZBG contained an N-oxide donor atom moiety. Sulfonate ester derivatives of full-length MMPi based on these ROS-triggerable systems were synthesized. It was found that proMMPi with sulfonate ester protecting groups showed relatively high rates of cleavage in the presence of H2O2 to release the active MMPi. In vitro MMP inhibition studies confirmed a significant increase in inhibitory activity of proMMPi upon addition of H2O2, demonstrating the use of sulfonate esters to act as cleavable triggers for ROS-activated prodrugs.
