III published an article in Journal of Medicinal Chemistry. The title of the article was 《1-Amino-4-benzylphthalazines as Orally Bioavailable Smoothened Antagonists with Antitumor Activity》.COA of Formula: C11H14N4 The author mentioned the following in the article:
Abnormal activation of the Hedgehog (Hh) signaling pathway has been linked to several types of human cancers, and the development of small-mol. inhibitors of this pathway represents a promising route toward novel anticancer therapeutics. A cell-based screen performed in our laboratories identified a new class of Hh pathway inhibitors, 1-amino-4-benzylphthalazines, e.g. I, that act via antagonism of the Smoothened receptor. A variety of analogs were synthesized and their structure-activity relationships determined This optimization resulted in the discovery of high affinity Smoothened antagonists, one of which was further profiled in vivo. This compound displayed a good pharmacokinetic profile and also afforded tumor regression in a genetic mouse model of medulloblastoma. After reading the article, we found that the author used (R)-6-(3-Methylpiperazin-1-yl)nicotinonitrile(cas: 1057682-05-9COA of Formula: C11H14N4)
(R)-6-(3-Methylpiperazin-1-yl)nicotinonitrile(cas: 1057682-05-9) belongs to piperazines. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines.COA of Formula: C11H14N4
