74939-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74939-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,3 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74939-28:
(7*7)+(6*4)+(5*9)+(4*3)+(3*9)+(2*2)+(1*8)=169
169 % 10 = 9
So 74939-28-9 is a valid CAS Registry Number.

Functionalization of Sulfonamide-Containing Peptides through Late-Stage Palladium-Catalyzed C(sp3)-H Arylation

Bai, Qingqing,Tang, Jian,Wang, Huan

supporting information, p. 5858 - 5861 (2019/08/27)

Bioactive peptides are emerging as promising candidates of clinic therapeutics. Here, we report a method for late-stage functionalization of sulfonamide-containing peptides through Pd-catalyzed C(sp3)-H arylation. In this protocol, the backbone

Structure-Based Rationale Design and Synthesis of Aurantiamide Acetate Analogues - Towards a New Class of Potent Analgesic and Anti-inflammatory Agents

Suhas, Ramesh,Channe Gowda, Dase

, p. 850 - 862 (2012/06/04)

A series of new aurantiamide acetate analogues were synthesized by modifying its N-terminal substitution and the amino acid residue. The structure of all these compounds was established on the basis of analytical and spectral studies. All the new derivatives were evaluated in vivo for their analgesic activity by tail flick method in mice and anti-inflammatory activity against carrageenan-induced oedema in albino rats at different doses (25, 50 and 100mg/kg body weight). All the compounds exhibited significant pharmacological activity with no ulcerogenic liability. In particular, pentapeptides and tricosamers (30 amino acids) containing analogues have demonstrated high potency than the reference standards. These compounds hold promise for further development.

Development of supramolecular organo-gel based on tripeptide skeletons

Azuma, Eriko,Kuramochi, Kouji,Tsubaki, Kazunori

body text, p. 680 - 684 (2010/07/15)

Boc-Ser-Val-Gly-OCH2Ph (31) showed high gelation abilities in the aromatic solvents, particularly in toluene. The minimum gelation concentration of 31 in toluene was 10 mg/ml, suggesting that 2500 molecules of toluene were immobilized by each m
