Phenylalanine-based inhibitors of the Large Amino Acid Transporter 1 (LAT1) are disclosed. The compounds are useful in modulating the transcellular transport of substrates of LAT1 such as large neutral amino acids. The compounds are useful in immunomodulation therapies.

Phenylalanine-based LAT1 inhibitors and uses thereof

&#x3b2;-Substituted &#x3b2;-amino acids, &#x3b2;-substituted &#x3b2;-amino acid derivatives, and &#x3b2;-substituted &#x3b2;-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The &#x3b2;-substituted &#x3b2;-amino acid derivatives and &#x3b2;-substituted &#x3b2;-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the &#x3b2;-substituted &#x3b2;-amino acid derivatives and &#x3b2;-substituted &#x3b2;-amino acid analogs and methods of using the compounds for treating cancer are also disclosed. The &#x3b2;-substituted &#x3b2;-amino acid derivatives and &#x3b2;-substituted &#x3b2;-amino acid analogs exhibit selective uptake in tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo. The &#x3b2;-substituted &#x3b2;-amino acid derivatives and &#x3b2;-substituted &#x3b2;-amino acid analogs and (bio)isosteres exhibit cytotoxicity toward several tumor types.

Beta-substituted beta-amino acids and analogs as chemotherapeutic agents

&#x3b2;-substituted &#x3b2;-amino acids and analogs as chemotherapeutic agents and uses thereof

&#x3b2;-Substituted &#x3b3;-amino acids, &#x3b2;-substituted &#x3b3;-amino acid derivatives, and &#x3b2;-substituted &#x3b3;-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The &#x3b2;-substituted &#x3b3;-amino acid derivatives and &#x3b2;-substituted &#x3b3;-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates, capable of passing through the blood-brain barrier, and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the &#x3b2;-substituted &#x3b3;-amino acid derivatives and &#x3b2;-substituted &#x3b3;-amino acid analogs and (bio)isosteres and methods of using the compounds for treating tumors are also disclosed. The &#x3b2;-substituted &#x3b3;-amino acid derivatives and &#x3b2;-substituted &#x3b3;-amino acid analogs and (bio)isosteres exhibit an improved selectivity toward tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo. The &#x3b2;-substituted &#x3b3;-amino acid derivatives and &#x3b2;-substituted &#x3b3;-amino acid analogs and (bio)isosteres exhibit an increased efficacy on a variety of tumor types.

&#x3b2;-substituted &#x3b3;-amino acids and analogs as chemotherapeutic agents

Pantoic acid ester neopentyl sulfonyl ester prodrugs of acamprosate, pharmaceutical compositions comprising such prodrugs, and methods of using such prodrugs and compositions thereof for treating diseases are disclosed. In particular, acamprosate prodrugs exhibiting enhanced oral bioavailability and methods of using acamprosate prodrugs to treat neurodegenerative disorders, psychotic disorders, mood disorders, anxiety disorders, somatoform disorders, movement disorders, substance abuse disorders, binge eating disorder, cortical spreading depression related disorders, tinnitus, sleeping disorders, multiple sclerosis, and pain are disclosed.
