Disclosed herein are liquid pharmaceutical formulations comprising levodopa amino acid conjugates that may further comprise a decarboxylase inhibitor, such as carbidopa, an antioxidant, a solvent, or any other pharmaceutically acceptable excipient. Further disclosed are methods of treating generative conditions and/or conditions characterized by reduced levels of dopamine in the brain, such as Parkinson's disease, comprising administering the disclosed liquid pharmaceutical formulations. Disclosed also are LDAA conjugate compounds.
An efficient method for the preparation of arylnaphthalenelignans (ANLs) was developed, which is based on the Photo-Dehydro-Diels–Alder (PDDA) reaction. While intermolecular PDDA reactions turned out to be inefficient, the intramolecular variant using suberic acid as tether linking two aryl propiolic esters smoothly provided naphthalenophanes. The irradiations were performed with a previously developed
