Check Digit Verification of cas no

The CAS Registry Mumber 51686-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,8 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 51686-78:
(7*5)+(6*1)+(5*6)+(4*8)+(3*6)+(2*7)+(1*8)=143
143 % 10 = 3
So 51686-78-3 is a valid CAS Registry Number.

Imidazolyl benzimidazoles and imidazo[4,5-b]pyridines as potent p38α MAP kinase inhibitors with excellent in vivo antiinflammatory properties

Mader, Mary,de Dios, Alfonso,Shih, Chuan,Bonjouklian, Rosanne,Li, Tiechao,White, Wesley,de Uralde, Beatriz Lopez,Sanchez-Martinez, Concepcion,del Prado, Miriam,Jaramillo, Carlos,de Diego, Eugenio,Martin Cabrejas, Luisa M.,Dominguez, Carmen,Montero, Carlos,Shepherd, Timothy,Dally, Robert,Toth, John E.,Chatterjee, Arindam,Pleite, Sehila,Blanco-Urgoiti, Jaime,Perez, Leticia,Barberis, Mario,Lorite, Maria Jose,Jambrina, Enrique,Nevill Jr., C. Richard,Lee, Paul A.,Schultz, Richard C.,Wolos, Jeffrey A.,Li, Li C.,Campbell, Robert M.,Anderson, Bryan D.

, p. 179 - 183 (2008)

Herein we report investigations into the p38α MAP kinase activity of trisubstituted imidazoles that led to the identification of compounds possessing highly potent in vivo activity. The SAR of a novel series of imidazopyridines is demonstrated as well, resulting in compounds possessing cellular potency and enhanced in vivo activity in the rat collagen-induced arthritis model of chronic inflammation.

Effective synthesis of benzimidazoles-imidazo[1,2-a]pyrazine conjugates: A comparative study of mono-and bis-benzimidazoles for antitumor activity

Singh, Iqubal,Luxami, Vijay,Paul, Kamaldeep

, p. 546 - 561 (2019/08/01)

A novel series of 6-substituted-8-(1-cyclohexyl-1H-benzo[d]imidazole-6-yl)imidazo[1,2-a]pyrazine and 6-substituted-8-(1-benzyl-1H-benzo[d]imidazole-6-yl)imidazo[1,2-a]pyrazine is first time synthesized and screen in vitro biological activity for 60 human cancer cell lines representing nine different cancer types. Derivatives 10 and 36 show antitumor activity for all tested cell lines, display comparable full panel mean-graph midpoint growth inhibition (MG_MID GI50) values of 2.10 and 2.23 μM, respectively. Furthermore, these derivatives show strong binding interactions with DNA and bovine serum albumin (BSA), studied through absorption, emission, and circular dichroism techniques. These spectroscopic studies reveal that imidazo[1,2-a]pyrazine-benzimidazoles 10 and 36, intercalate with ct-DNA as a leading interaction for fundamental biologically significant effects, with monobenzimidazole show better activity than bisbenzimidazole. These experiments have confirmed that the imidazo[1,2-a]pyrazine and benzimidazole moieties are efficient pharmacophores to trigger binding to DNA. These compounds have also interacted with bovine serum albumin protein that demonstrating high values of binding constant.

Synthesis and: In vitro evaluation of naphthalimide-benzimidazole conjugates as potential antitumor agents

Singh, Iqubal,Luxami, Vijay,Paul, Kamaldeep

, p. 5349 - 5366 (2019/06/07)

A series of novel naphthalimide-benzimidazoles was designed and synthesized for the first time and studied for their effect on antiproliferative activity. Some of these compounds possessed good antitumor activity towards the tested cancer cell lines. Noticeably, (diethylamino)ethyl 15 and (dimethylamino)ethyl 23 derivatives displayed superior antiproliferative activity towards human cancer cell lines with MG-MID GI50 values of 1.43 and 1.83 μM, respectively. Preliminary investigation revealed that compounds 15 and 23 might bind with ct-DNA through the intercalation mode which is responsible for potent bioactivity. Moreover, transportation behaviour indicated that these molecules could efficiently bind to and be carried by bovine albumin, and the hydrogen bonding and hydrophobic interactions played important roles in interaction with serum albumin.

Importance of 5/6-aryl substitution on the pharmacological profile of 4?-((2-propyl-1H-benzo[d]imidazol-1-yl)methyl)-[1,1?-biphenyl]-2-carboxylic acid derived PPARγ agonists

Obermoser, Victoria,Mauersberger, Robert,Schuster, Daniela,Czifersky, Monika,Lipova, Marina,Siegl, Monika,Kintscher, Ulrich,Gust, Ronald

supporting information, p. 590 - 603 (2016/12/09)

In this structure-activity relationship study, the influence of aryl substituents at position 5 or 6 on the pharmacological profile of the partial PPARγ agonist 4‘-((2-propyl-1H-benzo[d]imidazol-1-yl)methyl)-[1,1‘-biphenyl]-2-carboxylic acid was investigated. This lead was previously identified as the essential part of telmisartan to induce PPARγ activation. Para-OCH3-phenyl substitution strongly increased potency and efficacy independent of the position. Both compounds represent full agonists because of strong hydrophobic contacts with the amino acid Phe363 in the ligand binding domain. Partial agonists with higher potency than telmisartan or the lead were obtained with OH or Cl substituents at the phenyl ring. Molecular modeling suggested additional hydrogen or halogen bonds with Phe360 located at helix 7. It is assumed that these interactions fix helix 7, thereby promoting a partial agonist conformation of the receptor. The theoretical considerations correlate very well with the results from the luciferase transactivation assay using hPPARγ-LBD as well as those from a time-resolved fluorescent resonance energy transfer (TR-FRET) assay in which the coactivator (TRAP220, PGC-1α) recruitment and corepressor (NCoR1) release pattern was investigated.
