In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis, Structure-Activity Relationships, and in Vivo Efficacy of the Novel Potent and Selective Anaplastic Lymphoma Kinase (ALK) Inhibitor 5-Chloro-N2-(2-isopropoxy-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(2-(isopropylsulfonyl)phenyl)pyrimidine-2,4-diamine (LDK378) Currently in Phase 1 and Phase 2 Clinical Trials, published in 2013-07-25, which mentions a compound: 1184917-16-5, Name is 4-Bromo-2,5-dichloropyridine, Molecular C5H2BrCl2N, Computed Properties of C5H2BrCl2N.

The synthesis, preclin. profile, and in vivo efficacy in rat xenograft models of the novel and selective anaplastic lymphoma kinase inhibitor (I; LDK378) are described. In this initial report, preliminary structure-activity relationships (SARs) are described as well as the rational design strategy employed to overcome the development deficiencies of the first generation ALK inhibitor (II; TAE684). Compound I is currently in phase 1 and phase 2 clin. trials with substantial antitumor activity being observed in ALK-pos. cancer patients.

This literature about this compound(1184917-16-5)Computed Properties of C5H2BrCl2Nhas given us a lot of inspiration, and I hope that the research on this compound(4-Bromo-2,5-dichloropyridine) can be further advanced. Maybe we can get more compounds in a similar way.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Temple, Kayla J.; Engers, Julie L.; Long, Madeline F.; Gregro, Alison R.; Watson, Katherine J.; Chang, Sichen; Jenkins, Matthew T.; Luscombe, Vincent B.; Rodriguez, Alice L.; Niswender, Colleen M.; Bridges, Thomas M.; Conn, P. Jeffrey; Engers, Darren W.; Lindsley, Craig W. researched the compound: 4-Bromo-2,5-dichloropyridine( cas:1184917-16-5 ).Quality Control of 4-Bromo-2,5-dichloropyridine.They published the article 《Discovery of a novel 3,4-dimethylcinnoline carboxamide M4 positive allosteric modulator (PAM) chemotype via scaffold hopping》 about this compound( cas:1184917-16-5 ) in Bioorganic & Medicinal Chemistry Letters. Keywords: muscarinic acetylcholine receptor M4 pos allosteric modulator SAR; M(4); Muscarinic acetylcholine receptor; Positive allosteric modulator (PAM); Structure activity relationship (SAR). We’ll tell you more about this compound (cas:1184917-16-5).

This Letter details our efforts to replace the 2,4-dimethylquinoline carboxamide core of our previous M4 PAM series, which suffered from high predicted hepatic clearance and protein binding. A scaffold hopping exercise identified a novel 3,4-dimethylcinnoline carboxamide core that provided good M4 PAM activity and improved clearance and protein binding profiles.

There are many compounds similar to this compound(1184917-16-5)Quality Control of 4-Bromo-2,5-dichloropyridine. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
