-
Paragraph 0152; 0156, (2017/08/25)
The invention discloses a tricyclic compound as a PI3K/mTOR inhibitor. The tricyclic compound is a compound with the general formula (I) in the specification, wherein Ar is selected from aryl or heteroaryl; X, Y and Z are independently selected from O, CR2R3 and NR4 respectively; Q is selected from O, CR2R3 and NR4 or does not exists; R1 represents C1-C6 alkyl; n is selected from integers from 0 to 4; when n is more than or equal to 2, two R1 and a morpholine cycle can be combined into a combined cycle, a bridge cycle or a spiral cycle; R2 and R3 are selected from hydrogen and C1-C6 alkyl; R4 is selected from hydrogen, C1-C6 alkyl, C3-C7 cycloalkyl, heterocyclic radical, acyl and sulfonyl. The invention further discloses a perpetration method of the compound with the general formula (I) as well as a pharmaceutical composition and application of the compound with the general formula (I).

The unprecedented carbodiimide-mediated condensation between pyridines and anthranilic acids via pyridine dearomatization at room temperature has been developed to provide a straightforward approach to pyridoquinazolones. The value of this approach has further been demonstrated by its application to one-step, gram-scale syntheses of a series of pyridoquinazolone-based natural products and their analogues from readily available starting materials.

The series of vasicine (1) analogues, an alkaloid from Adhatoda vasica Nees., were synthesized with changes in A, B or C rings. Compounds 3-19 were evaluated for in vitro bronchodilatory activity using isolated guinea pig tracheal chain. Compounds 3-8 were also synthesized in good yields using microwave-mediated synthesis under solvent free conditions. Compounds 5 and 8 with seven-member C ring were more active than etofylline and caused 100% relaxation of both the histamine and acetylcholine pre-contracted guinea pig tracheal chain. The structure-activity relationship studies showed that the quinazoline and oxo functionalities were essential for activity. The compounds without C ring and instead having aliphatic and phenyl substitutions in B ring showed relaxation against histamine pre-contracted tracheal chain only, 2-methyl substituted analogues, 12 and 13, being most active with 100% relaxation effect.
