120138-50-3 Usage

Description

Quinupristin is a streptogramin antibiotic that blocks peptide bond formation and peptide extension in bacteria. Quinupristin is usually combined with another streptogramin antibiotic, dalfopristin , to produce quinupristin-dalfopristin complex , known commercially as Synercid. While both quinupristin and dalfopristin have bacteriostatic effects, they act synergistically to kill Gram-positive bacteria, as well as some Gram-negative and anaerobic bacteria.

Uses

Different sources of media describe the Uses of 120138-50-3 differently. You can refer to the following data:
1. Semisynthetic depsipeptide type I streptogramin. An antibacterial agent.
2. Quinupristin is a semi-synthetic analogue of virginiamycin B (ostreogyrcin B, pristinamycin IA, streptogramin B) formed by a Mannich condensation and elimination to generate an exocyclic methylene alpha to the ketone of the 4-piperidinone. Addition of quinucidinylthiol to the methylene group affords quinupristin. The structural changes provide a more hydrophobic compound with a readily ionisable group for generating a salt. Quinupristin is used commercially in synergistic combination with dalfopristin (30:70). There is little published data on the synthesis, biological or antibiotic activity of quinupristin alone, however the combination product is highly effective, including activity against antibiotic resistant strains.

Check Digit Verification of cas no

The CAS Registry Mumber 120138-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,3 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120138-50:
(8*1)+(7*2)+(6*0)+(5*1)+(4*3)+(3*8)+(2*5)+(1*0)=73
73 % 10 = 3
So 120138-50-3 is a valid CAS Registry Number.
