, (2018/10/27)
The invention belongs to the field of pharmaceutical and chemical industry, and provides a preparation method of a novel substituted pyridine pyrimidine compound. The pyridine pyrimidine compound is of great significance to medical research and new drug development. The problem that an amide compound is easily destroyed by strong alkalis in a synthesis process under a high temperature condition issolved, and meanwhile the problem that a pyrimidine 4-amino group is difficult to react to synthesize amide due to poorer amino activity is solved. Moreover, a two-step reaction for reducing a nitrogroup into an amino group and hydrolyzing cyano group into the amide group is completed in a one-step reaction, thereby simplifying the reaction flow. The invention provides a preparation method of the compound. The compound provides important support for the application of the compound in the field of new drug development in the future in terms of synthesis conditions, methods and processes.

Natriuretic peptide receptor A (NPR-A) agonists were evaluated in vivo by optimizing the structure of quinazoline derivatives to improve agonistic activity for rat NPR-A. A 1,4-Cis-aminocyclohexylurea moiety at 4-position and hydroxy group of D-alaninol at 2-position on the quinazoline ring were found to be important factors in improving rat NPR-A activity. We identified potent quinazoline and pyrido[2,3-d]pyrimidine derivatives against rat NPR-A, with double-digit nanomolar EC50 values. The in vivo results showed that compound 56b administered at 1.0 mg/kg/min significantly increased plasma cGMP concentration and urine volume in rats. We discovered novel potent NPR-A agonists that showed agonistic effects similar to those of atrial natriuretic peptide.

The present application provides novel quinazolines and azaquinazolines and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in for co-regulating RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways by administering a therapeutically effective amount of one or more of the compounds of formula (I), wherein X, Y, T and R4, and R6 to R8' are defined herein, to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment/ the disease is cancer.
