  • Patent number: 6384076
    Abstract: It has now been found that N-L-alpha-aspartyl-L-phenylalanine 1-methyl ester (APM) exhibits antisickling properties. In vitro testing verified that APM significantly lowered the frequency of sickling of red blood cells from each of twelve pediatric aged patients being treated for sickle-cell anemia by exchange transfusion. Sickling was also inhibited in an “index” patient after oral administering of APM. These in vitro and in vivo results identify APM as a therapeutic agent for the family of sickle cell molecular diseases.

  • Patent number: 6365591
    Abstract: The invention relates to novel N-(substituted phenyl)-N′-[&ohgr;-(3-substituted phenyl-4-isoxazolecarbonylamino)alkyl]piperazines, their N-oxides, and pharmaceutically acceptable salts thereof. The compounds are endowed with enhanced selectivity for alpha1-adrenergic receptors and a low activity in lowering blood pressure. The compounds are useful in the treatment of obstructive syndromes of the lower urinary tract, including benign prostatic hyperplasia (BPH), and in the treatment of lower urinary tract symptoms (LUTS) and neurogenic lower urinary tract dysfunction (NLUTD), and other conditions.
