Compounds having general structure I are provided. X and Y are independently selected from the group consisting of CH 2 , N, NR 9 , C=O, C=S, S=O, SO 2 , S, O, (CR 6 R 7 ) n , C(=O)-(CR 6 R 7 ) n , and C(=S)-(CR 6 R 7 ) n , where n is 1, 2, or 3. W is selected from the group consisting of (1a) and (1b). L is selected from the group consisting of N, O, S=O, SO 2 , C(O), NC(O), NC(S), OC(O), OC(S), C(NR 10 ), C(NOR 10 ), and a covalent bond. Z 1 , Z 2 , and Z 3 are independently selected from the group consisting of substituted carbon and nitrogen. Compounds of formula I are agonists of the melanocortin-4 receptor (MC-4R) and therefore may have useful properties for controlling diseases related to MC-4R action in humans, such as obesity and type II diabetes. |
