GC25560

Larazotide

Also known as 2-[[(2S)-1-[(2S)-5-amino-2-[[(2S)-2-[[(2S)-2-[[(2S)-2-[[2-[(2-aminoacetyl)amino]acetyl]amino]-3-methylbutanoyl]amino]-4-methylpentanoyl]amino]-3-methylbutanoyl]amino]-5-oxopentanoyl]pyrrolidine-2-carbonyl]amino]acetic acid

Larazotide(AT-1001) is an antagonist of Zonulin, which appears safe and well-tolerated and may offer potential benefit as an adjuvant to immune-targeted therapies
