Abstract: A DDR1 inhibitor compound can have a structure of Formula A, derivative thereof, prodrug thereof, salt thereof, stereoisomer thereof, tautomer thereof, polymorph thereof, or solvate thereof, or having any chirality at any chiral center, ring A is a ring structure; ring B is a ring structure; the X1, X2, X3, X4, and X5 are each independently a carbon or a hetero atom with or without a substituent; the Y is a linker; and each R1, R2, R3, R5, and R6 is independently a substituent; and each n is an integer, such as from 0 to the maximum number of allowed substituents on the linker or ring, wherein R5 and/or R6 is optionally nothing.
