FA-Ala-Lys-OH is a lysine derivative with a molecular weight of 243.2 daltons and a pKa of 6.5. It has been shown to be biologically active in humans and animals, and can be used as an amino acid supplement for patients with liver disease or kidney failure who require dialysis. FA-Ala-Lys-OH binds to the creatine kinase receptor on the surface of cells and causes cell lysis, which may be due to its ability to bind to the enzyme's allosteric site. This compound also has anti-viral properties, inhibiting the growth of recombinant virus mcf-7 in vitro by binding to erythrocyte membranes and disrupting protein synthesis. The 6-Fluoro-3-indoxyl beta D galactopyranoside is an antituberculosis drugs that belongs to the class of rifamycins. Rifapentine inhibits bacterial

Z-Phe-Leu-OH is a protease inhibitor that belongs to the group of peptidyl-protease inhibitors. It inhibits the activity of a wide range of proteases and is specifically active against carboxypeptidases A and B. Z-Phe-Leu-OH has been shown to be specific for these enzymes, with no inhibitory activity against other proteases such as aminopeptidases, serine proteases, or metalloproteases. The amino acid composition of this protease inhibitor is different from other inhibitors that have been studied in detail. This agent was found to be more effective than phenylmethylsulfonyl fluoride (PMSF) at inhibiting carboxypeptidase A and B.
Z-Phe-Leu-OH has been shown to be an acidic compound with a pKa of 5.5; however, it does not react with chloromethyl ketone

Suc-Ala-Gly-Pro-Phe-pNA is an amide that has been synthesized for the stabilization of proteins, peptides and nucleic acids. It has shown to be effective in preventing isomerization of casein and phosphatase (casein kinase II) by stabilizing the alpha helix structure. Suc-Ala-Gly-Pro-Phe-pNA also prevents fk506 binding to endoplasmic reticulum protein tyrosine kinases and isomerizes tyrosine to phenylalanine. The tetrapeptide sequence has been shown to be similar to sequences found in cellular proteins. This compound is a synthetic analog of the natural amino acid proline and can be used as a substitute in peptides or nucleotide sequences, due to its ability to stabilize these molecules against proteolysis or hydrolysis.

F-Phe-Ala-OH is a peptidyl amide that is ionizable at physiological pH. It has a constant and kinetic residue, as well as a hydrophobic, uncharged, and carboxypeptidase activity. F-Phe-Ala-OH catalyzes transpeptidation reactions between the amino acid residues of proteins. This reaction involves the elimination of one water molecule from the peptide bond to form an amine and an imine, which are then hydrolyzed to form the new peptide bond. The optimum pH for this catalysis is acidic.

Z-Phe-Leu-Ala-OH is a homologous protein that has been shown to have proteolytic activity. It has a neutral pH and is stable in the presence of metal ions. This enzyme is structurally similar to subtilisin, with a sequence of residues containing two histidine residues, which are important for stability. The kinetic parameters of this enzyme were determined by analyzing its activity under different conditions and at different temperatures. The mutant Z-Phe-Leu-Ala-OH was found to be more active than the wild type at high temperature, but less active at low temperature, suggesting that the protein could be used as an industrial catalyst in food processing or chemical production.

Fmoc-N-Me-Arg(Pbf)-OH is a radiopharmaceutical that is used in binding assays for the detection of cancer. It is a synthetic analog of the natural amino acid, lysine. The Fmoc group attaches to the terminal amine on one end of the molecule and is linked to the carboxylic acid on the other end through an ester bond. This allows for attachment of different drugs or other molecules to create a variety of analogs. Fmoc-N-Me-Arg(Pbf)-OH has been shown to have good binding properties with respect to cancer cells in vivo and diagnostic applications.

Ac-Ala-Ala-Ala-Ala-OMe is a peptidase that hydrolyzes the ester bonds of the hydrophobic amino acid residues, such as alanine, valine, leucine, and isoleucine. This enzyme deacylates and releases these amino acids from the side chain of their corresponding fatty acyl groups. Ac-Ala-Ala-Ala-Ala-OMe also acts on N terminal and C terminal residues. The presence of a scissile bond in the peptide substrate is required for this enzyme to function. Acetylation reactions are concurrent with acylation reactions, which produce an acetylated peptide product.

H-Phe-Met-OH is a postulated, synthetic, odorant binding molecule that has been reported to have high specificity for leukemia cells. H-Phe-Met-OH binds specifically to the surface of leukemia cells and stabilizes them. It also potentiates the effect of other drugs used in leukemia therapy. These properties make it an ideal candidate for developing new treatments for leukemias.
