247035-44-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 247035-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,3 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 247035-44:
(8*2)+(7*4)+(6*7)+(5*0)+(4*3)+(3*5)+(2*4)+(1*4)=125
125 % 10 = 5
So 247035-44-5 is a valid CAS Registry Number.

(2S)-Benzeneslfonylamino-3-[3-methoxy-4-{4-(1,4,5,6-tetrahydropyrimidin-2- ylamino)piperidin-1-yl}benzoylamino]propionic acid, MN-447, is a potent antagonist of the integrins αvβ33 and αIIbβ3 Herein, we report a novel synthetic protocol that produces MN-447 in an overall yield of 45%. This protocol, when compared with the original synthetic route for MN-447, is more cost-effective, requires fewer steps, does not require chromatographic purification of intermediates and MN-447, and increases the overall yield by 35%. This report focuses on the synthetic strategies that were developed for this protocol. Now, the large quantities of MN-447 that are needed for preclinical and toxicological studies can be readily obtained.

, (2008/06/13)

An objective of the present invention is to provide compounds having integrin αvβ3antagonistic activity, cell adhesion inhibitory activity, GP IIb/IIIa antagonistic activity, and/or human platelet aggregation inhibitory activity, and, therapeutic agents for treating cardiovascular diseases, angiogenesis-related diseases, cerebrovascular diseases and the like and for inhibiting platelet aggregation. The derivatives according to the present invention are compounds represented by formula (I) or pharmaceutically acceptable salts or solvates thereof: wherein A represents a five- to seven-membered heterocyclic group containing two nitrogen atoms or the like; D represents >NH2, >CH2or the like; X and Z represent CH or a nitrogen atom; R7and R8represent alkyl, halogen or the like; Q represents >C═O, >CH2or the like; R9represents H, alkyl, aralkyl or the like; R10represents H, alkynyl or the like; R11represents H, substituted amino or the like; R12represents H or alkyl; m is 0 to 5; n is 0 to 4; p and q are each 1 to 3; and r is 0 or 1.
