Inhibitor compounds and cancer treatment methods

A method of treating endometrial cancer in a mammal in need thereof comprising administering a therapeutically effective amount of a compound comprising a compound of Formula I or IA:

• a pharmaceutically-acceptable salt, hydrate, solvate, tautomer, optical isomer, and/or combination thereof;
• wherein:
• R1 and R2 together form a substituted or unsubstituted polycyclic ring comprising at least two ring systems, said at least two ring systems comprising a first ring system bonded to C1 and a second ring system fused to the first ring system, wherein:
• the first ring system is a substituted or unsubstituted aromatic group, the second ring system is a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, a substituted or unsubstituted carbocyclic group, or a substituted or unsubstituted heterocyclic group;
• or
• the first ring system is a substituted or unsubstituted heteroaromatic group, the second ring system is a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, a substituted or unsubstituted carbocyclic group, or a substituted or unsubstituted heterocyclic group;
• or
• the first ring system is a substituted or unsubstituted saturated carbocyclic group, the second ring system is a substituted or unsubstituted aromatic group, a substituted or unsubstituted unsaturated carbocyclic group, a substituted or unsubstituted heterocyclic group, or a substituted or unsubstituted ring B:
• wherein X1 to X6 are each independently selected from carbon or a heteroatom;
• or
• the first ring system is a substituted or unsubstituted unsaturated carbocyclic group, the second ring system is a substituted or unsubstituted aromatic group, a substituted or unsubstituted carbocyclic group, a substituted or unsubstituted heterocyclic group, or a substituted or unsubstituted ring B:
• wherein X1 to X6 are each independently selected from carbon or a heteroatom;
• or
• the first ring system is a substituted or unsubstituted heterocyclic group, the second ring system is a substituted or unsubstituted heteroaromatic group, a substituted or unsubstituted carbocyclic group, or a substituted or unsubstituted heterocyclic group;
• and
• R3 to R11 are each independently selected from H, a substituted or unsubstituted hydrocarbon group, a substituted or unsubstituted heterogeneous group, a substituted or unsubstituted carbocyclic group, a substituted or unsubstituted heterocyclic group, substituted or unsubstituted aromatic, or a substituted or unsubstituted heteroaromatic;
• R12 is selected from H or a hydrocarbyl group;
• Y is selected from a heteroatom;
• Ring is selected from a substituted or unsubstituted thiomorpholinyl group, a substituted or unsubstituted morpholinyl group, or a substituted or unsubstituted piperidinyl group, wherein the nitrogen in the Ring is bonded to A;
• A is selected from a substituted or unsubstituted hydrocarbon group, a substituted or unsubstituted heterogeneous group, a substituted or unsubstituted carbocyclic group, a substituted or unsubstituted heterocyclic group, substituted or unsubstituted aromatic, or a substituted or unsubstituted heteroaromatic;
• and
• n is 0 or 1.
