2-Methyl-2-[(dodecylsulfanylthiocarbonyl) sulfanyl]
propanoic acid was prepared in this laboratory by following a previous method in the literature [33],
Flurbiprofen (2-[3-Fluoro-4-biphenyl]
propanoic acid) belongs to
propanoic acid derivatives (Chunhua et al., 2012) which represent the largest class of NSAIDs (Elliott et al., 1988).

Kainic acid, 2-amino-3-(5-methy1-3-oxo-1,2-oxazol-4-y1),
propanoic acid (AMPA), and cyclothiazide (CTZ) were purchased from Tocris Biosciences (UK).
Nishiyama reports that midazolam, which is itself a water soluble benzodiazepine derivative by virtue of being a benzodiazepine-GABAA receptor complex agonist, exhibits synergistic analgesia for thermally-induced acute nociception as well as persistent inflammatory nociceptive activation both with N-Methyl-DAspartica Acid (NMDA) and 2-amino-3-(5- methyl-3-oxo-12-oxazol-4-yl)
Propanoic Acid (AMPA) receptor antagonists.18 Goodchild et al also reported that intra-thecal midazolam caused spinally mediated anti- nociception by a mechanism involving opioid receptor activation, and Bahar et al showed its anaesthetic affects.19,20

Lactic acid is capable to produce various chemicals such as acrylic acid,
propanoic acid, acetaldehyde, 2,3-pentanedione (Gunter et al., 1994, 1995; Waldley et al., 1997; Varadarajan and Miller, 1999), as well as biodegradable poly lactic acid.
Studies have shown that analogs of AMPA (2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)
propanoic acid and Br-HIBO (2-amino-3-(4-bromo-3-hydroxyisoxazol-5-yl)
propanoic acid are antagonists for the metabotropic glutamic acid receptors.
The thiadiazolate containing potassium based framework was synthesized by adding 2-(2-fluorobiphenyl-4-yl)
propanoic acid hydrazide (1 mmol, 0.258 g) to an ice cooled alcoholic potassium hydroxide solution containing 2 mmoles (0.112 g) of KOH.
Due to the existence of a chlorine atom in the [alpha]-chloropropanoic acid's molecular structure, its acidic density and reactivity are stronger than those of
propanoic acid, which is more active in chemical reactions [1-4].
Byproducts such as acetic acid, 1--pentanol,
propanoic acid were produced along with ethanol in negligible quantity.
