  • Patent number: 11833256
    Abstract: The invention relates to compositions and methods as part of a pharmacotherapeutic strategy that targets the endochondral ossification process in a pharmacologically selective and site-specific manner. A variety of orthopedic pathologies are caused by or associated with generalized or local dysregulation of endochondral ossification, for example trauma to the bone growth plate or diaphysis can cause a serious imbalance in bone growth, leading to progressive deformity that today can only be treated surgically. Dysregulated endochondral ossification is also behind heterotopic ossification, which arises in soft tissues and causes pain, decrease in mobility and other clinical problems. The invention therefore provides RARy agonist and antagonist nanoparticle compositions for treating abnormal endochondral ossification and bone growth that can deliver robust local therapeutic control over a particular long bone's growth with a long-lasting effect.

  • Publication number: 20130079514
    Abstract: (R)-2-Arylpropionamide compounds of formula (I), pharmaceutical preparations of the compounds and a process for making the compounds are described. The 2-Arylpropionamides of the invention are useful in the prevention and treatment of tissue damage due to the exacerbated recruitment of polymorphonuclear leukocytes and monocytes at inflammatory sites. In particular, the invention relates to the R enantiomers of omega-aminoalkylamides of 2-aryl propionic acids, of formula (I), for use as inhibitors of chemotaxis of neutrophils and monocytes induced by the C5a fraction of complement and by other chemotactic proteins whose biological activity is associated with activation of a 7-TD receptor. Selected compounds of formula (I) are dual inhibitors of both the C5a-induced chemotaxis of neutrophils and monocytes and the IL-8-induced chemotaxis of polymorphonuclear leukocytes.
