Biologically active fragment of bradykinin
Biochem/physiol Actions
The bradykinin (BK) fragment (1-5) (RPPGF) is among the most stable of naturally occurring metabolites. It may be used as a marker for BK production in vivo. It is known that an intact Arg residue in the C-terminus is required for biological activities. BK 1-5 is the minimal peptide that inhibited α-thrombin-induced platelet aggregation and secretion and calcium mobilization. It also prevented α-thrombin from cleaving the thrombin receptor peptide, NATLDPRSFLLR, between arginine and serine. Such antithrombin activities of BK 1-5 may contribute to the cardioprotective nature of kinins.
Check Digit Verification of cas no
The CAS Registry Mumber 23815-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,1 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23815-89:
(7*2)+(6*3)+(5*8)+(4*1)+(3*5)+(2*8)+(1*9)=116
116 % 10 = 6
So 23815-89-6 is a valid CAS Registry Number.

Scandium(III) triflate-promoted serine/threonine-selective peptide bond cleavage

The site-selective cleavage of peptide bonds is an important chemical modification that is useful not only for the structural determination of peptides, but also as an artificial modulator of peptide/protein function and properties. Here we report site-selective hydrolysis of peptide bonds at the Ser and Thr positions with a high conversion yield. This chemical cleavage relies on Sc(iii)-promoted N,O-acyl rearrangement and subsequent hydrolysis. The method is applicable to a broad scope of polypeptides with various functional groups, including a post-translationally modified peptide that is unsuitable for enzymatic hydrolysis. The system was further extended to site-selective cleavage of a native protein, Aβ1-42, which is closely related to the onset of Alzheimer's disease.
