A series of dipeptide derivatives of l-dopa were synthesized and investigated for their pharmacological activity using the unilaterally 6-hydroxydopamine (6-OHDA)-lesioned rat as an experimental model of Parkinson's disease. Among them, (S)-isopropyl 2-(2-amino-2-methylpropanamido)-3-(3,4- dihydroxyphenyl)propanoate (4g) was found to be the most active compound, with 106% AUC activity and 149% peak activity of l-dopa after oral administration.

Effervescent enteric coated L-dopa formulation and method of using the same

Therapeutic levels of L-DOPA are achieved by orally administering a pharmaceutical effervescent-enteric coated tablet comprising: A. a member selected from the group consisting of L-DOPA or a derivative thereof capable of enzymatically cleaving and reverting to L-DOPA in vivo, B. a non-toxic pharmaceutically acceptable inert diluent, C. a non-toxic pharmaceutically acceptable carbon dioxide releasing agent, D. a non-toxic pharmaceutically acceptable effervescing agent, and E. a non-toxic pharmaceutically acceptable enteric coating. This composition is extremely useful in the treatment of Parkinsonism. When administered to warm-blooded animals (e.g., humans), superior therapeutic blood levels of L-DOPA are observed over that normally observed with conventional enteric coated formulations.

There is provided, novel, transient pro-drug forms of L-DOPA (3,4-dihydroxy-L-phenylalanine), having the formula: STR1 wherein n represents an integer of from 2 to 50 with respect to formula (V-A), and wherein n represents an integer of from 1 to 50 with respect to formula (V-B); R represents a hydrogen atom, an acyl group, STR2 --CO-pyridyl, or --CO--R3, wherein R3 is the residue of any N,N-C1 -C2 dialkylamino acid or a C4 -C6 cycloalkylamino acid; R1 represents --OH, --O-lower alkyl, --O-benzyl, or a naturally occurring protein amino acid; and R2 represents STR3 --CO-pyridyl, a naturally occurring protein amino acid, 3',4'-L-diacyloxy phenylalanine, or --CO-R3. These compounds are all useful in the treatment of Parkinson's Disease.
