2-Amino-4,8-naphthalenedisulfonic acid is a structural analog of the natural amino acid phenylalanine. It is an inhibitor of the enzyme tyrosinase, which participates in the oxidation of dopamine to DOPA and subsequent conversion to melanin. 2-Amino-4,8-naphthalenedisulfonic acid has been shown to inhibit the growth of probiotic bacteria and can be used as a food additive. The compound also inhibits the oxidation catalyst that is required for some analytical chemistry tests. 2-Amino-4,8-naphthalenedisulfonic acid has been shown to have toxicological properties in animal studies and this toxicity is exacerbated by its ability to bind with pyridine nucleotides found in cells. The toxicological effects are thought to be related to the inhibition of protein synthesis that leads to cell death.

D-Asparagine monohydrate is a white crystalline powder that is soluble in water and has a molecular weight of 98.1 g/mol. It inhibits the growth of bacteria by preventing the formation of β-lactamase, which can lead to antibiotic resistance. D-Asparagine monohydrate is used as an additive in the preparation of polyacrylamide gel for electrophoresis and other purposes. It has been found that it can be used as an inhibitor of recombinant proteins, such as those produced by E. coli, with high kinetic activity. It also inhibits the crystallization process and growth rate of Mycobacterium licheniformis.

22,23-Dihydrobrassicasterol is a sterol present in rhizoma gastrodiae that has been shown to inhibit the growth of oral pathogens. It also has been found to have cholesterol-lowering effects and can be used as an antimicrobial agent to treat gastrointestinal diseases. 22,23-Dihydrobrassicasterol has been found to have inhibitory effects on human serum processes such as the process of producing fibroblasts and on physiological functions such as the inhibition of hepatic steatosis. The pharmacokinetic properties of this drug are not well understood, but it appears to be absorbed from the gut and excreted in urine.

1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.

b-Propiolactone is a plant extract that is found in soybeans. It has been shown to have antiviral properties and can inhibit the growth of certain viruses. b-Propiolactone binds to the active site of an enzyme called RNA polymerase, which blocks RNA synthesis and inhibits viral replication. This compound has also been shown to inhibit virus replication in vitro assays as well as antibody response against hepatitis B. The biological effects of b-propiolactone are thought to be due to its ability to bind with group p2 protein monoclonal antibodies, which may have implications for the prevention of pandemic influenza.

4-Chlorocinnamic acid is a malonic acid derivative and one of the cinnamic acid derivatives that has been shown to inhibit many chemical reactions. It inhibits the production of tyrosinase, which is an enzyme that catalyzes the conversion of tyrosinase to 4-hydroxycinnamic acid. 4-Chlorocinnamic acid also inhibits the growth of Candida glabrata in vitro. The effect on candida is due to its ability to inhibit the production of hydroxyl group and aromatic hydrocarbon, both of which are required for candida's survival. 4-Chlorocinnamic acid binds with aryl halide and neutral ph, preventing it from reacting with other substances.

3-Hydroxy-6,2',4',5'-tetramethoxychalcone (3HTMC) is a fine chemical that is used as a versatile building block in the synthesis of various organic compounds. 3HTMC is soluble in most organic solvents and can be used as an intermediate for the preparation of other organic compounds. This chemical has been shown to be effective in the formation of complex compounds with high quality. 3HTMC is available in bulk quantities at competitive prices.

Pentazocine lactate is an opioid that binds to the kappa-opioid receptor. It has a low potency and is used as an analgesic. Pentazocine lactate has been shown to be effective in the treatment of eosinophilic fasciitis, which is a rare inflammatory disease of the skin and soft tissue. Side effects for this drug include respiratory depression and sedation, constipation, nausea/vomiting, urinary retention, erythema multiforme, pruritus, erythema nodosum, thrombocytopenia, and fever. Pentazocine lactate may also interact with other drugs such as antidepressants or antipsychotics.

Applications Guanosine-5'-triphosphate disodium salt (CAS# 56001-37-7) is a nucleotide used in the preparation of photoreactive GTP affinity probes, and in inhibitors of eukaryotic initiation factor eIF-4E.

Applications N-Acetylethylene Urea-d4 (cas# 1189701-94-7) is a compound useful in organic synthesis.

Sodium N-lauroylsarcosinate is a surfactant that is used in water treatment, wastewater treatment, and as a detergent. It is also used as an analytical tool for the titration calorimetry of sodium salts. Sodium N-lauroylsarcosinate is a sodium salt that belongs to the group of sodium salts. It has been shown to have biological properties such as permeability through human serum and biodegradability. The salt form of this compound has an electrochemical impedance spectrum which can be used to identify it.

1-(3-Chlorophenyl) thiourea is a curcumin analog that has been shown to inhibit the epidermal growth factor (EGF) receptor. It is synthesized from 1,2-dichlorobenzene and urea in a two-step process. The anhydrous potassium carbonate is first converted to the potassium salt with an acid chloride. The second step is the reaction of this salt with urea in the presence of excess anhydrous potassium carbonate. This product has been shown to be effective against cancer cells and may be used as a potential anticancer agent for treatment of skin cancer. 1-(3-Chlorophenyl) thiourea inhibits EGF receptor by binding to it and preventing its activation, which prevents cell proliferation and reduces tumor size.

Applications The formation of p-Cresol-(methyl-13C) via phenol methylation at higher temperature from the deactivation of basic catalyst.
