Peyronie's disease (PD) is often physically and psychologically devastating for patients, and the goal of treatment is to improve symptoms and sexual function without adding treatment-related morbidity. The potential for treatment-related morbidity after more invasive interventions, e.g. surgery, creates a...

Histone deacetylase inhibitors have been actively explored as a new generation of chemotherapeutics for cancers, generally known as epigenetic therapeutics. Two novel series of N-(2-amino-phenyl)-4-{[(2/3/4-substituted-phenylcarbamoyl)-methyl]-amino}-butyramide and N-(2-amino-phenyl)-4-{[(2/3/4-substituted-phenylcarbamoyl)-methyl]-amino}benzamide were designed and synthesized as novel histone deacetylase inhibitors. The anticancer potential of...
