  • Patent number: 9475824
    Abstract: Disclosed are fused pyrimidine compounds having scaffolds composed of left and right rings, the left ring being a saturated carbocyclic or heterocyclic ring and the right ring being a pyrimidine ring. The left saturated ring is fused to the pyrimidine ring at the 5 and 6 carbons of the pyrimidine. The saturated ring may be 5 or 6 members in size and may be all carbon or may contain a single oxygen, sulfur or nitrogen atom as one of the non-fused members of the ring. The pyrimidine ring is substituted at the two position by a 5:6 bicyclic aromatic heterocycle such as indole, benzimidazole or benzopyrazole and at the four position by an aryl methyl amino group. The 5:6 bicyclic aromatic heterocycle is substituted at its 2 position by hydrogen or an aliphatic or functional aliphatic group and at the 4 position by a functional group as described herein. The aryl methyl amino group may be aminobenzyl or aminomethyl-substituted phenyl.
