Abstract
Disclosed are novel compounds that are useful in regulating the expression of interleukin-6 (IL-6) and/or vascular cell adhesion molecule-1 (VCAM-1), and their use in the treatment and/or prevention of cardiovascular and inflammatory diseases and related disease states, such as, for example, atherosclerosis, asthma, arthritis, cancer, multiple sclerosis, psoriasis, and inflammatory bowel diseases, and autoimmune disease(s). Also, disclosed are compositions comprising the novel compounds, as well as methods for their preparation.
Claims12
A method for reducing IL-6 and/or VCAM-1 in a subject, comprising administering a therapeutically effective amount of at least one compound of Formula V:
- or a stereoisomer, tautomer, pharmaceutically acceptable salt, or hydrate thereof, wherein:
- Q is selected from CR6 and nitrogen;
- U is selected from C═O, C=S, SO2, S═O, SRi, CRi R2, CR1OR2, and CR1SR2;
- Y is selected from oxygen, sulfur, NR6, and CR6R7;
- A is C1-C4 alkyl, wherein the alkyl chain may be connected to Y, D, Rb3 and/or Rb5 to form a cycloalkyl or heterocycle;
- D may be absent or present, and if present is selected from ORi, NR1 R2,
- R1 and R2 are independently selected from hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, sulfonamide, carboxamide, acyl, and nitrile, wherein R1 and R2 may be connected to form a cycloalkyl or a heterocycle;
- R6 and R7 are independently selected from hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, C1-C6 alkoxy, hydroxyl, and halogen;
- Ra2 and Ra3 are independently selected from hydrogen, C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, C1-C6 alkoxy, C3-C6 cycloalkyl, halogen, amino, amide, hydroxyl, and heterocycle, wherein Rai and Ra2 and/or Ra2 and Ra3 may be connected to form a cycloalkyl or a heterocycle;
- Ra1 is C1-C6 alkoxy;
- Rb2 and Rb6 are independently selected from hydrogen, halogen, C1-C6 alkyl, and C3-C6 cycloalkyl;
- and
- Rb3 is selected from hydrogen, halogen, C1-C6 alkyl, C3-C6 cycloalkyl, C1-C6 alkoxy, hydroxyl, and amino, wherein
- Rb2 and Rb3 and/or Rb5 and Rb6 may be connected to form a cycloalkyl or a heterocycle,
- provided that
- at least one of Rai, Ra2, and Ra3 is not hydrogen;
- and
- if Ra1 and Ra3 are both hydrogen, and Y is NR6, then Ra2 is not hydrogen, —OAc, or —OMe.
