Patent number: 6784167
Abstract: 17-beta-hydroxysteroid dehydrogenase-II inhibitors having the structural formula
wherein the phenyl group labeled A and the group —C(R4)(R6)Y are oriented cis to each other; W represents O or S; R1 represents —H or optionally substituted —(C1-C4)alkyl; n represents 0 or an integer of 1-3; and R2 represents any of a variety of substituents on ring A. R4 generally represents —H but may be a bond terminating at the ortho position of ring A. Y represents fluorine, —OR5, or —SR5, and R5 represents —H, optionally substituted —(C1-C4)alkyl, optionally substituted -phenyl, optionally substituted —(C1-C4)alkyl-phenyl, or optionally substituted —(C1-C4)acyl. R6 represents any of a variety of groups as defined in the specification and claims, including heteroaryl, arylalkyl, heteroarylalkyl, arylalkenyl, heteroarylalkenyl, alkynyl, arylalkynyl, heteroarylalkynyl, aryl, and indolyl.

Patent number: 6716840
Abstract: Compounds having the general structure I are provided:
X and Y are independently selected from the group consisting of CH2, N, NR9, C═O, C═S, S═O, SO2, S, O, (CR6R7)n, C(═O)—(CR6R7)n, and C(═S)—(CR6R7)n, where n is 1, 2, or 3. W is selected from the group consisting of
and L is selected from the group consisting of N, O, S, S═O, SO2, C(O), NC(O), NC(S), OC(O), OC(S), C(NR10), C(NOR10), and a covalent bond. Z1, Z2, and Z3 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.
