Herein, we disclose a new series of TYK2/ JAK1 inhibitors based upon a 3.1.0 azabicyclic substituted pyrimidine scaffold. We illustrate the use of structure-based drug design for the initial design and subsequent optimization of this series of compounds. One advanced example 19 met program objectives for potency, selectivity and ADME, and demonstrated oral activity in the adjuvant-induced arthritis rat model.

Paragraph 0643, (2016/03/14)
A compound having the structure: or a pharmaceutically acceptable salt thereof, wherein X is N or CR, where R is hydrogen, deuterium, C1-C4 alkyl, C1-C4 alkoxy, C3-C6 cycloalkyl, aryl, heteroaryl, aryl(C1-C6 alkyl), CN, amino, alkylamino, dialkylamino, CF3, or hydroxyl; A is selected from the group consisting of a bond, C═O, —SO2—, —(C═O)NR0—, and —(CRaRb)q—, where R0 is H or C1-C4 alkyl, and Ra and Rb are independently hydrogen, deuterium, C1-C6 alkyl, C3-C6 cycloalkyl, aryl, aryl(C1-C6 alkyl), heteroaryl, (C1-C6 alkyl)heteroaryl, etc.; A′ is selected from the group consisting of a bond, C═O, —SO2—, —(C═O)NR0′, —NR0′(C═O)—, and —(CRa′Rb′)q—, where R0′ is H or C1-C4 alkyl, and Ra′ and Rb′ are independently hydrogen, deuterium, C1-C6 alkyl, C3-C6 cycloalkyl, aryl, aryl(C1-C6 alkyl), heteroaryl, (C1-C6 alkyl)heteroaryl, heteroaryl(C1-C6 alkyl), and heterocyclic(C1-C6 alkyl); Z is —(CH2)h— or a bond, where one or more methylene units are optionally substituted by one or more C1-C3 alkyl, CN, OH, methoxy, or halo, and where said alkyl may be substituted by one or more fluorine atoms; R1 and R1′ are independently selected from the group consisting of hydrogen, deuterium, C1-C4 alkyl, C3-C6 cycloalkyl, aryl, heteroaryl, aryl(C1-C6 alkyl), CN, etc., wherein said alkyl, aryl, cycloalkyl, heterocyclic, or heteroaryl is further optionally substituted with one or more substituents selected from the group consisting of C1-C6 alkyl, halo, CN, C1-C4 alkylamino, C3-C6 cycloalkyl, etc.; R2 is selected from the group consisting of hydrogen, deuterium, C1-C6 alkyl, C3-C6 cycloalkyl, halo, and cyano, where said alkyl may be substituted by one or more fluorine atoms; R3 is selected from the group consisting of hydrogen, deuterium, and amino; R4 is monocyclic or bicyclic aryl or monocyclic or bicyclic heteroaryl wherein said aryl or heteroaryl is optionally substituted with one or more substituents selected from the group consisting of C1-C6 alkyl, heterocycloalkyl, halo, C3-C6 cycloalkyl, etc., where said alkyl, cycloalkyl, alkoxy, or heterocycloalkyl may be substituted by one or more C1-C6 alkyl, halo, CN, OH, alkoxy, amino, —CO2H, —(CO)NH2, —(CO)NH(C1-C6 alkyl), or —(CO)N(C1-C6 alkyl)2, and where said alkyl may be further substituted by one or more fluorine atoms; R5 is independently selected from the group consisting of hydrogen, C1-C6 alkyl, C1-C6 alkoxy, and hydroxyl; h is 1, 2 or 3; j and k are independently 0, 1, 2, or 3; m and n are independently 0, 1 or 2; and, q is 0, 1 or 2. Also provided are methods of treatment as Janus Kinase inhibitors and pharmaceutical compositions containing the compounds of the invention and combinations with other therapeutic agents.
