    摘要: The invention provides crystalline forms of 6-[(5S,9R)-9-(4-cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-7-yl]nicotinic acid, its pharmaceutically acceptable salts, or solvates, thereof Further, a process is provided for preparing substituted spiro-hydantoin compounds of the formula I wherein Z is N or CR4b; K and L are independently O or S; Ar is an optionally substituted aryl or heteroaryl; A1, A2, G, and Q are linkers; and R2, R4a, R4c, and R16 are defined in the specification. The process includes the reaction of N-substituted glycine compound and methylene precursor compound with an alkene compound. The substituted spiro-hydantoin compounds of formulae I and II are useful in the treatment of immune and/or inflammatory diseases.
