Known as a nonsteroidal anti-inflammatory drug (NSAID), Meloxicam is commonly used to treat pain or inflammation caused by rheumatoid arthritis and osteoarthritis in adults. It is also used to treat juvenile rheumatoid arthritis in children who are at least 2 years old. It is effective to reduce pain, inflammation, swelling, and stiffness of the joints. Developed by Boehringer-Ingelheim, Meloxicam is a derivative of oxicam that can relieve the symptoms of arthritis, primary dysmenorrhea, fever with analgesic and antipyretic properties. Meloxicam was approved for use in April 2000.Anti-inflammatory effects of meloxicam function by inhibiting the prostaglandin synthetase (cyclooxygenase 1 and 2) which results in a decrease of the synthesis of prostaglandins. As prostaglandins are chemicals that contribute to inflammation especially within joints, which leads to the common symptoms of pain, tenderness, and swelling associated with arthritis, inhibition of their synthesis can be associated with the analgesic and antipyretic effects of meloxicam. As a result, inflammation and its accompanying symptoms are reduced. Meloxicam starts to relieve pain about 30 to 60 minutes after administration.

N-acetylglycine is used is in biological research of peptidomimetics. It is used as the blocking agent of the N-terminus to prepare unnatural and unusual amino acids and amino acid analogs as well as to modify peptides. N-Substituted glycine analogs are widely used in peptidomimetics and drug research.N-Acetyl-glycine is a derivative of Glycine (G615990). It is an intermediate used to synthesize rac 3-O-Methyl DOPA (M303805) which is an impurity of Levodopa.

Triethyl phosphite is used as a ligand in organometallic chemistry and as a reagent in organic synthesis. It is used as reference to phosphoric acid standard in 31P NMR spectroscopy. It acts as a reducing agent to prepare 2-phenylindazole from o-nitrobenzylidineaniline as well as reacts with electrophiles to get phosphonates. It forms a stable complex with copper(I) iodide. It finds application in a modified Staudinger reaction for the alkyl bromide to an amine through the azide. Further, it is also used in the preparation of 3-phenyl-2-substituted indoles by reacting with beta-nitro styrenes.Triethyl phosphite is an organophosphorus compound. It is used as a reducing agent; can react with electrophiles to form phosphonates or phosphates; forms a stable complex with copper(I) iodide.This reaction is currently used for the preparation of synthetically useful phosphonate reagents employed in modified retinal studies. Thus, diethyl 3-alkoxycarbonyl-2-propenylphosphonates are prepared in 72-91% yields by the reaction of methyl or ethyl 4-bromocrotonates with triethyl phosphite at 150-160C. Similarly, diethyl 3-(ethoxycarbonyl)-2 methyl-2-propenylphosphonate is prepared in 81% yield from triethyl phosphite and ethyl 3-methyl-4-chlorocrotonate by heating at 180- 200C.The diethyl (E)- and (Z)-3-ethoxycarbonyl-3 fluoro-2 -methyl-2-propenylphosphonates are respectively obtained from triethyl phosphite and (E)- or (Z)-4-bromo-2-fuoro-3-methyl-2-butenoates at 140C.
Reactivity ProfileTriethyl phosphite is colorless, moderately toxic liquid, combustible. Flammable when exposed to heat or flame. When heated to decomposition Triethyl phosphite emits toxic fumes of oxides of phosphorus [Lewis, 3rd ed., 1993, p. 1271].
Triethyl phosphite is a very good nucleophile. The carbon adjacent to the bromine is the most electrophilic position, and phosphorus is the only nucleophile. Triethyl phosphite displaces the bromine in an SN2-like process, and back attack by the bromide which is released generates a phosphonate product, in which the -protons are strongly acidic.The acute toxicity after oral, dermal, and inhalation exposure is relatively low. The oral LD50s in rats ranged between 1840 mg/kg bw (females) and 2470 mg/kg bw (males). Symptoms of rapid breathing and tremors were observed prior to death. In mice LD50 values above 3700 mg/kg bw were recorded. The 6-hour inhalation LC50 with an aerosol of 1.6-3.5 m MMAD in rats was between 11, 100 mg/m3 (females) and 11, 600 mg/m3 (males). Clinical signs included eye and upper respiratory irritation, salivation and rapid, shallow breathing. The dermal LD50 in rabbits was between 2800 mg/kg bw (males) and > 3000 mg/kg bw (females).
