Small molecule compound

The invention provides a small molecule compound. The small molecule compound is characterized in that the small molecule compound is a compound shown in a structural formula in the specification, ora stereoisomer, a geometric isomer, a tautomer, a racemate, a hydrate, a solvate, a metabolite, and a pharmaceutically acceptable salt or pro-drug thereof, wherein X1 and X2 are selected from carbon or nitrogen; Z is carbon or nitrogen; n1 is 0 and 1; n2 and n3 are the same or different, and are 0 or any natural numbers; a cyclic group represented by G is a saturated heterocyclic ring; any one orseveral hydrogen atoms on the saturated heterocyclic ring are substituted by R; and R is selected from hydrogen, halogen, alkyl, substituted alkyl, amino, amine group, substituted amine group, carboxyl, amido, substituted amido, ester group, substituted carbonyl, cycloalkyl, substituted cycloalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, substituted sulfonyl, and substituted sulfoxide group. The small molecule compound of the invention can be used to treat, prevent and alleviate autoimmune diseases and/or immune-related inflammatory skin diseases.

CYCLIC AMINOMETHYL PYRIMIDINE DERIVATIVE

The present invention provides a cyclic aminomethyl pyrimidine derivative and a pharmaceutically acceptable salt thereof with high selectivity for dopamine D4 receptors, which are useful for treating a disease such as attention deficit hyperactivity disorder. Specifically, a compound of formula (1) or a pharmaceutically acceptable salt thereof is provided, wherein n and m are independently 1 or 2; Ra is C1-6 alkyl group, C3-6 cycloalkyl group, or amino group; Rb is hydrogen atom, C1-6 alkyl group or the like, provided that when Ra is amino group, then Rb is hydrogen atom; Rc1 and Rc2 are independently hydrogen atom, or C1-6 alkyl group; Rd1 and Rd2 are independently hydrogen atom, fluorine atom or the like; ring Q is an optionally-substituted pyridyl group or an optionally-substituted isoquinolyl group; and the bond having a dashed line is a single or double bond.
