Abstract:
Compounds of formula (I) wherein: X is —O—, —S(O)r—, —CH2—, or —NR—, wherein r is 0, 1, or 2; X1, X2, and X5 are each independently CR7 or N; one of X3 or X4 is C and is attached by a single bond to -L-, and the other is CR7 or N, provided that no more than three of X1, X2, X3, X or X5 are N; Ring A is monocyclic C5-6scycloalkyl or a 5- to 6-membered monocyclic heterocyclyl comprising from 1 to 5 heteroatoms independently selected from N, S, or O; wherein Ring A is further optionally substituted with from 1 to 3 R4; provided that Ring A is not morpholinyl, thiomorpholinyl or tetrahydro-2H-pyranyl; L is a bond, —O—, —NR—, —S(O)n—, —CH2—, or —C(O)—, wherein n is 0, 1, or 2; 1 2 L1 is an C1-8alkylene, C3-scycloalkylene, —CH2-L2-, or a 3- to 8-membered heterocyclylene comprising 1 to 5; R1 is C6-20alkyl or a monocyclic C3-8cycloalkyl; wherein said C3-8cycloalkyl is substituted with at least one R6 and may be optionally substituted with from 1 to 5 additional R6 substituents, wherein R6 for each occurrence is independently selected; and R2 is —C(O)OR3, —C(O)N(R3)—S(O)2R3, —S(O)2OR3, —C(O)NHC(O)R3, —Si(O)OH, —B(OH)2, —N(R3)S(O)2R3, —S(O)2N(R3)2, —O—P(O)(OR3)2, or —P(O)(OR3)2, —CN, —S(O)2NHC(O)R3, —C(O)NHS(O)2R3, —C(O)NHOH, —C(O)NHCN, —CH(CF3)OH, —C(CF3)2OH, or a selected heteroaryl or heterocyclyl; and pharmaceutically acceptable salts thereof, can modulate the activity of one or more SIP receptors and/or the activity of autotaxin (ATX).
Abstract:
Compounds of formula (I) can modulate the activity of one or more S 1P receptors. Sphingosine 1-phosphate (S IP) is a lysophospholipid mediator that evokes a variety of cellular responses by stimulation of five members of the endothelial cell differentiation gene (EDG) receptor family, namely S1P1, S1P2, S1P3, S1P4, and S1P5 (formerly EDG1, EDG5, EDG3, EDG6 and EDG8). The EDG receptors are G-protein coupled receptors (GPCRs) and on stimulation propagate second messenger signals via activation of heterotrimeric G-protein alpha (Ga.) subunits and beta-gamma (G( )y) dimers.
Abstract:
Provided are compounds of Formula I, or pharmaceutically acceptable salts thereof, and methods for their use and production. Formula (I) The compounds are IRAK-4 inhibitors useful for treating an inflammatory disease, an autoimmune disease, cancer, a cardiovascular disease, a disease of the central nervous system, a disease of the skin, an ophthalmic disease and condition, and a bone disease.
Abstract:
Compounds that have agonist activity at one or more of the S1P receptors are provided. The compounds are sphingosine analogs that, after phosphorylation, can behave as agonists at S1P receptors.
