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 and evaluation of aniline headgroups for alkynyl thienopyrimidine dual EGFR/ErbB-2 kinase inhibitors, published in 2009-03-01, which mentions a compound: 23856-20-4, Name is 1-Benzyl-5-nitro-1H-indazole, Molecular C14H11N3O2, Application In Synthesis of 1-Benzyl-5-nitro-1H-indazole.
Aniline ‘headgroups’ were synthesized and incorporated into an alkynyl thienopyrimidine series of EGFR and ErbB-2 inhibitors. Potent inhibition of enzyme activity and cellular proliferation was observed In certain instances, protein binding was reduced and oral exposure was found to be somewhat improved relative to compounds containing the reference aniline.
Here is a brief introduction to this compound(23856-20-4)Application In Synthesis of 1-Benzyl-5-nitro-1H-indazole, if you want to know about other compounds related to this compound(23856-20-4), you can read my other articles.
