Abstract

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 R 4 , and R 6 to R 8′ 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.

First claim

What is claimed is:

1. A method for treating a disease or condition associated with dysregulation of at least one of RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways, comprising:
a dosing regimen wherein a therapeutically effective amount of a compound of formula (I) is administered to a patient in need thereof, and the dosing regimen comprises administration in a regular or an irregular schedule of the therapeutically effective amount of the compound of formula (I):

wherein:
X is CH or N;
Y is H, optionally substituted C 1 -C 6 alkyl, OR 1 or NR 2 R 3 ;
T is H or C 1 -C 6 alkoxy;
R 1 is optionally substituted C 1 -C 6 alkyl, optionally substituted (C 1 -C 6 alkyl)OH, optionally substituted (C 1 -C 6 alkyl)OC 1 -C 6 alkyl, optionally substituted C 3 -C 8 cycloalkyl, optionally substituted (C 1 -C 6 alkyl)NH 2 , optionally substituted (C 1 -C 6 alkyl)CO 2 H, or optionally substituted (C 1 -C 6 alkyl)CONH 2 ;
R 2 and R 3 are joined to form an optionally substituted heterocycle;

R 8′ is halogen.

2. The method according to claim 1 , wherein the administration of the compound regulates at least one of RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways.

3. The method according to claim 1 , wherein the compound is administered to the patient orally, by injection, inhalation, ocularly, transdermally, intravascularly, subcutaneously, intramuscularly, sublingually, intracranially, epidurally, rectally, or vaginally.

4. The method of claim 3 , wherein the inhalation administration is orally, intranasally or intratracheally.

5.
