3,4,5-Trimethoxybenzoic acid anhydride is a synthetic chemical compound that is used as a pharmaceutical intermediate. It is mainly used to prepare potent anticancer agents and potent anticancer drugs. 3,4,5-Trimethoxybenzoic acid anhydride reacts with amines in the presence of a base to form substituted amides. This reaction has been shown by crystal x-ray diffraction to be sensitive to the solvent polarity and temperature of the reaction medium. The compound can also react with chloride ion to form 3,4,5-trichlorobenzoic acid anhydride (3TCBA).

H-Gly-Arg-Gly-Asp-Ser-Pro-Cys-OH trifluoroacetate salt is a peptide that has been shown to inhibit the growth of tumor cells. It has also been shown to have biological properties in a number of experimental models, including in vitro and in vivo studies. H-Gly-Arg-Gly-Asp-Ser-Pro-Cys-OH trifluoroacetate salt inhibits muscle cell proliferation by binding to the extracellular matrix protein collagen type I. This inhibition leads to reduced tissue formation and body growth. This peptide also inhibits the proliferation of cancer cells by blocking the production of growth factor beta 1 (GFβ1).

H-Gly-Arg-Gly-Asp-D-Ser-Pro-OH trifluoroacetate salt (HGGDS) is a collagen gel that is used in the treatment of autoimmune diseases, such as arthritis and lupus. HGGDS inhibits the production of fibrinogen, which is a protein involved in blood clotting, by binding to its receptor on human fibroblasts. It also inhibits the production of basic proteins needed for the generation of collagen and activation of integrin receptors, which are involved in cell adhesion and migration. HGGDS also blocks transcription polymerase chain reactions (PCRs), which are necessary for the synthesis of DNA. This can lead to a decrease in cell proliferation and an increase in apoptosis.

H-Met-Arg-OH acetate salt is a metabolite of the amino acid L-methionine. It is also a dipeptide, which consists of two amino acids that are linked by an amide bond. The linkage between the amino acids in this compound is clockwise instead of the usual left to right orientation. This means that H-Met-Arg-OH acetate salt is not an essential amino acid and can be synthesized by the body. Salmonella typhimurium uses H-Met-Arg-OH acetate salt as a precursor for its synthesis of L-arginine and L-methionine, which are essential to bacterial growth and survival. Residues have been found in foods such as milk and eggs, and it has been shown that cotransduction can lead to resistance against antibiotics such as streptomycin and tetracycline.
