Abstract
This invention is directed to the novel use of arylurea compounds and aralkylura compounds consisting of phenylurea, benzylurea, and phenylethylurea or by a meta-or para-positioned, ring-substituted homolog of each in which one hydrogen is substituted by one methoxyl, methyl, or hydroxyl radical, for the palliation of sickle cell anemia and other human sickling disease.
The invention is also directed to pharmaceutical formulations containing these aromatic urea compounds.
The invention is also directed to pharmaceutical formulations containing these aromatic urea compounds.
