Inhibitors of arginase and their therapeutic applications

A method for the treatment of renal cell carcinoma, prostate cancer, colorectal cancer, breast cancer, skin cancer, lung cancer, ovarian cancer, and gastric cancer in a subject, comprising administering to the subject a therapeutically effective amount of at least one compound according to Formula II:

• wherein
• R6 is OH;
• R7 is H;
• X is (C3-C14)-cycloalkylene;
• Y is —NR′R″;
• M is selected from a bond, —(C1-C6)alkylene-, —O—, —C(O)—, —C(S)—, —C(O)NH—, —C(S)NH—, —S, —S(O)—, —S(O)2—, and —NR′—;
• R8 and R9 are each hydrogen,
• D is butylene;
• R′ and R″ are independently selected from H, (C1-C8)alkyl, —C(O)—(C1-C8)alkylene, optionally substituted (C3-C6)aryl, optionally substituted (C3-C14)aryl(C1-C6)alkylene-, optionally substituted (C1-C6)aminoalkyl, optionally substituted (C3-C6)cycloalkyl, optionally substituted (C3-C14)heterocycloalkyl, optionally substituted (C3-C14)heteroaryl;
• and
• wherein any alkyl, alkylene, aryl, heteroaryl, cycloalkyl, or heterocycloalkyl is optionally substituted with one or more members selected from halogen, oxo, —COOH, —CN, —NO2, —OH, —NRdRe, —NRgS(O)2Rh, (C1-C6)alkyl, (C1-C6)haloalkyl, (C1-C6)haloalkoxy, (C1-C6)alkoxy, (C3-C14)aryl, (C3-C14)heteroaryl, (C3-C14)heterocycloalkyl, (C3-C14)heteroaryl-(C1-C6)alkylene and (C3-C14)aryloxy;
• wherein Rd, Re, Rg, and Rh are each independently selected from H, straight or branched (C1-C6)alkyl, optionally substituted (C3-C14)aryl(C1-C6)alkylene-, optionally substituted (C3-C14)aryl, (C1-C6)hydroxyalkyl, (C1-C6)aminoalkyl, H2N(C1-C6)alkylene-, optionally substituted (C3-C6)cycloalkyl, optionally substituted (C3-C14)heterocycloalkyl, optionally substituted (C3-C14)heteroaryl, optionally substituted (C3-C14)aryl-(C1-C6)alkylene-, and NR′R″C(O)—,
• or a pharmaceutically acceptable salt, stereoisomer, tautomer, or prodrug thereof.
